a “usual state of air quality” after the fire

The results – eagerly awaited – of the first analyzes of deposits and concentrations of toxins in the air following the fire at the Lubrizol factory on September 26 in Rouen were made public Saturday afternoon by the prefect of the department during a press conference. These analyzes, which are available on the prefecture’s website, were carried out by the National Institute for the Industrial Environment and Risks (Ineris).

Pierre-André Durand wanted to be reassuring by announcing that the air quality in Rouen was in its “usual state”, even if he recognized that the “persistent and uncomfortable” smell was “anxiety-provoking”. “Tonight we have most of the analysis results which are encouraging in the sense that they translate to a normal situation for air quality,” insisted the prefect, who said that “the only exception” concerned the site itself, “where there is a presence of benzene”.

“We note the presence of lead in certain places, it being specified that it may be a historic source which is not due to the fire because the company does not use or had no device for lead whereas in urban areas there can be traces of lead right away, ”explained the prefect. Pierre-André Durand also confirmed “the presence of asbestos in the roofs of buildings” of the factory, ensuring that “the subject was identified and followed up”.

Published in the evening on the prefecture site, the results of the soot fallout analyzes generated by the thick cloud of smoke “do not highlight significant differences between the control sample and the five other sites located under the plume for PAHs (polycyclic aromatic hydrocarbons) ”.

Investigation extended to endangering others

The prefect of the Normandy region has also announced a “production and harvest freeze”: vegetables, fruits, milk, eggs, honey … will “be kept under the responsibility of the operator until health guarantees are obtained” . Another announcement: “It is possible” that some schools, those that did not have time to do a cleaning, are closed on Monday. Pierre-André Durand then answered questions from the press at length, stating in particular that 34 firefighters and 12 fire engines were still mobilized on the Lubrizol site.

Earlier in the afternoon, the prosecution announced that the investigation was expanding to the endangerment of others. “Complaints have been brought to the attention of the prosecution, within the jurisdiction of the tribunal de grande instance of Rouen or outside jurisdiction, and are addressed to it as and when. In view of these elements, the investigation is henceforth also carried out on the count of endangering others, “said the prosecutor of the Republic of Rouen Pascal Prache in a press release. Me Jonas Haddad, a lawyer in Rouen, said that he had been approached by several people, but also by companies, and expected “a hundred complaints”. “We can compare this to an oil spill in the air, it does not calm down,” he said.

Tense context

These first analyzes take place in a tense context, many residents of Rouen, associations and political figures expressing their impatience at the lack of information on the potential harmfulness of the plume of smoke that stretched over 22 kilometers during the fire. of the Seveso classified site, and thick oily fallout that covered the area.

On the Internet, many have expressed distrust of the authorities’ first statements on September 26 and 27. Posted on change.org, a petition calling for an investigation into the health and environmental consequences of the disaster has already collected more than 22,000 signatures. Elsewhere, on Facebook, a group offering free support and accommodation to Rouennais wishing to leave the city attracted more than 2,500 people.

Several left-wing MPs have demanded the opening of a parliamentary commission of inquiry. “We need the whole truth about #Lubrizol. As with #AZF 17 years ago, a parliamentary commission of inquiry must be opened as of next week “, argued Olivier Faure, number one of the PS, on Twitter. “We are asking for a parliamentary inquiry and an administrative inquiry!” This site has already experienced several accidents (2013, 2015, 2019) “, tweeted LFI MP Eric Coquerel, saying” angry “.

No panic in the hospital

“People who are there and do not know whether or not they are exposed to a health risk, it is absurd”, indignant Olivier Blond, president of the association “Breathe” for air quality . “We are facing an oil spill in the air, in the heart of a city. You can’t wait days and days to find out what’s going on, hundreds of thousands of people are potentially exposed, it’s preposterous. “

“We can understand a form of psychosis that has taken hold in a Norman population, and particularly in Rouen”, declared Sunday September 29 the Minister of Action and Public Accounts Gérard Darmanin at the “Grand Rendez-Vous” Europe 1 -CNEWS-Les Echos. “I don’t think there is a transparency problem,” he said. “What is done and what will have to be done is to publish all of the studies and analyzes, so that everyone in the public domain can see.”

Contacted by Le Figaro, the Rouen University Hospital does not report any particular influx. “We have had 16 visits since yesterday, only one remained under observation for a few hours,” says an official. “Patients complain of itchy nose and throat, crying eyes, breathing problems, sometimes headache, symptoms of peak pollution. People are more anxious than severely affected, but there is no panic. “


Five maps to visualize regional disparities facing Covid-19

INFOGRAPHICS – The President of the Republic ruled out Thursday the possibility of segmenting deconfinement geographically. The Covid-19 crisis, however, hit the territories very unevenly. Here are all the maps to see clearly.

Grand Est and Île-de-France on the front line.
Grand Est and Île-de-France on the front line. DR.

The appearance of the first centers of epidemic, the famous “clusters”, in Oise with the death of a first Frenchman on February 25 and in Haut-Rhin with the evangelical meeting of Mulhouse from March 3 to 5 surely explain the overrepresentation of the number of deaths in the three major regions of the northeast quarter of France.

This hypothesis of “clusters” acting as accelerators of the epidemic is also found at the subregional level. Thus Haute-Savoie (home of Balme-de-Sillingy) is distinguished from its Savoyard neighbor while Morbihan (home of Carnac) also stands out in Brittany. We will also note an over-representation of deaths in departments with large urban centers as well as along the Saône-Rhône axis.

These regional differences continue to persist over time since we find these same regions and departments if we look at the current number of people hospitalized. As if the pandemic had been limited to these territories. Without doubt one of the effects of confinement, which made it possible to limit interregional movements and therefore the circulation of the coronavirus.

The fact of having succeeded in preserving certain territories has allowed the overloaded hospitals of the Grand Est, Île-de-France, Bourgogne-Franche-Comté and Corsica to be able to evacuate some of their most seriously ill patients and d ” thus absorb the peak of the epidemic.

Chance at the time of the peak of the epidemic, this heterogeneity may however be a problem at the time of deconfinement. In fact, according to the Institut Pasteur, we will find these disparities in the rate of people infected. Very high in the Grand Est and in Île-de-France, even if we are still far from group immunity, this rate is likely to frighten the inhabitants of the less affected regions. Regions which are for the most part large tourist regions (Atlantic coast and Mediterranean coast) and therefore particularly attractive for the millions of future unsettled. They will then have to choose between the desire to preserve themselves and the restarting of their tourism industry.

Coronavirus would damage the inner walls of blood vessels

This peculiarity could explain various symptoms such as poor oxygenation of the blood or certain brutal organ failures.

Doctors have noted an increased risk of microthrombosis: the formation of small clots in the blood that can block the millions of blood capillaries in the human body.

To say that we are going from surprise to surprise with the Covid-19 infection is an understatement. First presented as an atypical pneumonia, the disease continues to accumulate strangeness. Starting with the unexpected symptoms: skin lesions, loss of taste (ageusia) and / or smell (anosmia), transient or not, neurological disorders (read above), kidney and heart damage, etc.

The list of people at risk, too, presents some incongruities. Smokers, for example, are five times less likely to be infected than others (but are more likely to get worse when they get the disease). Men and the obese are very overrepresented, gender and weight being independent risk factors as shown by detailed statistical analyzes. Children on the contrary are not very infected, not very contagious, and present very little risk of being hospitalized. So much the better, of course, but it’s amazing for an infection

what to know this Friday, April 24

Good evening,

Today, on this 39th day of confinement, as the date of deconfinement approaches, the French are wondering if their summer holidays will take place. In Europe, many countries opt for a national tourism even if Greece still hopes to attract foreign visitors. Nothing will be done without them masks essential in transport and soon available promises the government. On the side of the medical community, we are worried about possible neurological damage due to Covid-19 while an American study questions the resistance of the virus to heat and sunlight.

1. Where is the epidemic?

The coronavirus epidemic has killed 22,245 people in France since the beginning of March, including 389 new deaths recorded in 24 hours. In detail, 13,852 people died in hospitals and 8,393 in nursing homes and other medico-social establishments, said Jérôme Salomon, the director general of health, in his daily update this evening. Another 28,658 people are hospitalized but the number of patients in intensive care, 4,870 cases today, continues to decline, continuing for 16 days. 43,496 patients are now cured and discharged from the hospital.

Virus circulation remains high“, However, recalled Jérôme Salomon. In total in France, 122,557 cases of contamination have been confirmed since the start of the epidemic.

2. What happened today

Will we go on vacation this summer? Beyond the date of May 11, many French people think about their summer vacation and worry that they will not be able to leave. During a meeting this morning with representatives of the catering and tourism sector, Emmanuel Macron and his ministers announced that the decision on the reopening date and the details of the support plan will be clarified in May. In the meantime, the outdoor accommodation is already working on a health charter. But faced with Covid-19, regional disparities are blatant. For the most attractive regions, “it will then be necessary to choose between the desire to preserve themselves and the restarting of their tourist industry“, Analyzes Guillaume Balavoine of the Infography department. Especially since the crossovers of the summer could reduce our efforts to nothing.

Traveling in Europe. To avoid chaos this summer, Brussels calls on European countries to coordinate in order to allow citizens to travel without health risks in the Schengen area. Tourism however will remain mainly national. This is what Italy is planning for its first summer without foreign tourists. Even if the German owners of “fincasIn Mallorca are unhappy, our neighbors across the Rhine are also getting used to the idea of ​​staying within their borders. Greece, on the other hand, still hopes to welcome foreign tourists and is doing everything it can to carry out express tests at Athens airport.

Masks coming soon. The French will be able to start purchasing masks for the general public “from 4 may“Said the Secretary of State to the Minister of Economy, Agnès Pannier-Runacher. Town halls, pharmacies, supermarkets … Several distribution methods are envisaged. Once equipped, the French can then resume transport at the end of confinement. Metro, bus, train, plane, all are preparing for recovery. RATP President, Catherine Guillouard, plans to “relight 70% of its traffic on 11 may” But, like in China, aren’t the worried French going to favor the car? “After May 11, considers a transport specialist, there is an extremely high risk of the explosion of the private car, in contradiction with ecological requirements

Still many questions about the coronavirus. The Sars CoV-2 never stops questioning the medical community, reports Cécile Thibert from the science department. In addition to the pulmonary and digestive symptoms, doctors suspect neurological damage due to viruses. Another question on the coronavirus: can the heat and the rays of the sun weaken it? This is what suggests an American study which has, moreover, led Donald Trump in new rantings on possible treatments based on UV and disinfectants. As for the debate on the infectious nature of the virus in the air, “it is far from settled ”, reminds our journalist Anne-Laure Frémont who looks at the role of ventilation and air conditioning systems in confined spaces.

3. Dressing, listening, cooking …

Get dressed. Avoid the trap, do not abdicate. Jogging, old T-shirt, the temptation is great for the confined to let go on the dress level. “Without putting on your thirty-one, it is important to continue to dress carefully“Advises Marine de La Horie, Fashion journalist. For men, soft materials and bright colors are to be preferred. They preserve the mood and make the containment bearable. And above all, separate the hours of the day. According to stylist Caroline Vilstrup, “Dressing specifically for work in the morning signals to your brain that you are ready. Changing at the end of the day will also allow you to better disconnect

Drink with moderation). Closed, some restaurateurs engage in take-out sales and take the opportunity to offer the vintages of the winemakers who supply it. “It is not a question of competing with the wine merchants but of making our customers profit from part of the stock of our cellar with, for us, a low margin“Explains chef Christian Constant in Paris. In the 9th arrondissement, Chez Gegeor, customers are there. For the young boss, “when they are still receiving a salary, people seek pleasure. They cook, buy good meat, good products and buy a good wine” “The goal is not to make money, but to try to save the house! ”, he specifies.

It is striking that the group, which started in London in the early 1960s, is as hard-hitting and responsive to the news.

Olivier Nuc, music critic about the Rolling Stones

Listen. The rock veterans took us by surprise. The Rolling Stones released a new song last night, a prelude to a new album. For our music critic Olivier Nuc who “feared the worst“, Living in a Ghost Town (“Living in a ghost town”) is ultimately “what we expected more: a good original Rolling Stones title” The song would even be “the most convincing single of the English veterans since Saint of Me, in 1997” With this premonitory text, written well before confinement, “it is striking that the group, which started in London in the early 1960s, is as hard-hitting and responsive to the news“Notes the journalist.

To cook. Missing the sandwich? Swallowed at the corner of the office or enjoyed in a country picnic, it was a staple of our unconfined life. Fanny Rey offers you a very chic version: the smoked trout and rocket sandwich. Inspired by the mountain from which she returns, the Michelin-starred chef from Saint-Rémy de Provence, offers you a very delicious recipe which “allows you to escape the routine of the classic sandwich and renew the charms of the picnic while simply cooking with products that are easy to find” “The powerful and peppery flavor of arugula, she specifies, harmoniously balances the sweet and reassuring side of the dill cream. “

4. Especially for our subscribers

Go around a confined world. Le Figaro has mobilized its correspondents to show you around the capital every day at the time of the Covid-19 pandemic. Discover Istanbul, the intrepid megalopolis that “turns each weekend into an urban ghost” Or Kiev, surrounded by massive forest fires. He breathes an air “apocalypse” In New Delhi, a city of striking contrasts between rich and poor, solidarity is organized while “Berlin, the hedonistCannot stop living. Santiago, Los Angeles… the journey continues.

6. Containment, instructions for use

Despite the containment measures, it is possible to leave your home in several cases:

  • Go to your place of work, if teleworking is impossible.
  • Do your shopping in “authorized local shops”.
  • Go to the doctor or pharmacy.
  • Travel to babysit or care for “vulnerable” people.
  • Make brief trips, one hour maximum and within a radius of one kilometer, related to individual physical exercise.
  • Go to judicial or administrative summons.
  • Participate in missions of general interest at the request of the administrative authority.

In the event of an inspection, you must present a certificate to the police. It can be downloaded here, on a smartphone or be written by hand. The document must be completed at each outing to justify the reason. Violators are liable to a fixed fine of 135 euros, or even 1500 euros in the event of a repeat offense.

7. The reflexes to adopt

A few simple gestures help limit the spread of the virus. Here they are :

  • Wash your hands every hour.
  • Cough or sneeze into the crease of his elbow.
  • Use disposable tissues.
  • Avoid kissing or shaking hands.
  • Wear a mask when you are sick.
  • Limit your movements as much as possible.

Covid-19 is transmitted by saliva, through close contact with an infected person, especially when the person coughs or sneezes. The virus also remains viable for a few hours on different surfaces.

The disease manifests itself in several symptoms. In 9 out of 10 cases, this results in a fever below 39 ° C. According to the World Health Organization, this fever is most often accompanied by a state of tired, of signs ofshortness of breath and a dry cough.

8. What to do in case of symptoms?

The most important thing is not to go immediately to a general practitioner or to the emergency room to avoid infecting more people. Wearing a mask is highly recommended. For the rest, the recommendations of the Ministry of Health differ from case to case.

Stay at home, if you don’t show up little or no symptoms, taking care not to contaminate your loved ones. If you have a fever, take paracetamol. Possibly plan a follow-up teleconsultation with your doctor.

Yes you feel a difficulty breathing, with feeling of suffocation, after having felt proud and a cough for several days, call 15. The centers 15 being overflowed, rhinitis and fever or cough well tolerated should not be the subject of a call.

See you tomorrow.


Is there really reason to hope for a less contagious coronavirus this summer?

The White House has released a study showing that the virus has poor resistance to heat, humidity and direct sunlight. Could this be an indication of its seasonality, already invoked by Donald Trump?

William Bryan, head of the Science & Technology department at the White House during the press briefing on April 23.

THE QUESTION. At a White House press conference on Thursday, a senior official in the Department of Homeland Security, Bill Bryan, presented the elements of a study showing that the new SARS-CoV-2 coronavirus was poorly resistant to an atmosphere very hot and humid, as well as direct sunlight.

Elements that support the statements made by President Donald Trump at the beginning of February. “The virus we are talking about, many people think it will go away in April as the heat arrives», He assured then. Could these new elements thus reinforce the hope that the virus could be less contagious with the arrival of summer?

CHECK. The study, carried out in a Maryland laboratory dedicated to bacteriological threats, has not been published or even posted online. But some boards of a presentation were made available by Yahoo News. We learn that two very different types of analysis

Does Prevotella really play a role in infection?

The virus attacks a bacteria found in the body, according to an astonishing theory that flourishes on social networks. But is it even slightly founded?

Researchers are wondering about the role played by the intestinal microbiota.

THE QUESTION. Is the SARS-CoV-2 virus a bacteriophage? That is to say, it would act by infecting a bacteria, naturally present in the body: Prevotella. By becoming virulent, this bacterium would trigger the immune hyper-reaction causing complications.

This theory was developed by Sandeep Chakraborty, who presents himself as a bioinformatics researcher at the University of California at Davis and Bio moon, a French SVT teacher has been circulating on social networks for a few days. What is it exactly?

CHECK. And let’s face it: for the specialists interviewed by Le Figaro, this theory does not hold water: “She is attractive, but the problem is that she is based on false assumptions”, insists Professor Harry Sokol, gastroenterologist at Saint-Antoine hospital and specialist in microbiota. “I feel like I am facing an exquisite corpse. We put reasoning and hypotheses end to end

Does tobacco protect against infection?

Smokers are said to be very underrepresented among people infected with Covid-19. But is it really true?

A smoker wearing a mask in Wuhan, April 10.

THE QUESTION. Three weeks ago, tobacco specialist Bertrand Dautzenberg, a fierce opponent of cigarettes, dropped a small bomb on Twitter: smokers are widely underrepresented among patients infected with coronavirus in Chinese and American hospitals.

The figures are indeed striking. He asks himself this question: would tobacco protect, against all odds, from the Covid?

CHECK. At the time of the publication of this tweet, Professor Dautzenberg had given us a short interview. In all honesty, he himself did not know what to think of these figures except that the thing seemed very counter-intuitive. “I am the first surprised, and it embarrasses me, you can imagine. But the effect is so marked in the two datasets that the question is worth asking, even if there are many potential biases», He emphasized then. “Neither of the two studies in which these figures appear refer to them.

This is how the interstellar object Oumuamua was born

VIDEO – In 2017, a mysterious celestial body flew over our solar system. There were indications that it may have been built by extraterrestrials. Today we have new knowledge.

The Oumuamua interstellar object

By Norbert Lossau (Die Welt)

In October 2017, scientists detected the presence of an interstellar object in our solar system for the first time. He was baptized Oumuamua, the Hawaiian term for “Messenger”, because it was a Hawaii-based telescope that allowed its discovery. Back then, due to Oumuamua’s unusual features, Harvard researcher Abraham Loeb concluded that it must have been an object built by aliens – a spectacular thesis.

According to Loeb, a whole series of exotic characteristics supported this thesis. First, Oumuamua had a very unusual shape, measuring around 400 meters long and only 40 meters wide. This is why Oumuamua was also nicknamed the “Cosmic javelin”. In addition, the object had a smooth metallic surface with reddish reflections.

Oumuamua exceeds the authorized speed

And he didn’t exactly obey the laws of celestial mechanics. After going through the solar system, the body

in Crépy-en-Valois, the school served as an incubator for the epidemic

A study explores the path of the virus within the establishment and families.

The Crépy-en-Valois high school, north of Paris, was the first cluster in the coronavirus epidemic in France. It was in this Oise commune, affected by the epidemic in February, that the first Frenchman who died in the Covid-19 taught at college. Two months later, as the government prepares to lift the containment, a study by the Institut Pasteur highlights the important role played by the school in the spread of Sars-CoV-2. “Our objective was to provide a photograph of the epidemiological situation after the passage of the coronavirus”, indicates Pr Arnaud Fontanet, epidemiologist and first author of the study.

The scientists therefore returned on site from March 30 to April 4 to assess the contamination rate of students (but also their parents, brothers and sisters), teachers and other staff of the school. They used serological tests, which measure the presence of antibodies in the blood, and make it possible to detect individuals

Didier Raoult is right to speak of “fake news” about an American study?

Researchers have questioned the effectiveness of chloroquine. The French infectiologist refers to a study “closer to scientific fraud than a reasonable analysis”.

“Passion prevails over scientific analysis,” writes Raoult. Gérard Julien / AFP

THE QUESTION. The chloroquine debate continues to escalate. On Wednesday evening, Professor Didier Raoult, first defender of the hydroxychloroquine-azithromycin (HCQ-AZ) cocktail to fight Covid-19, strongly criticized a scientist opposed to her treatment on Twitter. The latter cited a preliminary American study published on Tuesday, which concluded that hydroxychloroquine (HCQ), taken with or without azithromycin (AZ), was ineffective.

“The witch hunter @MicrobiomDigest is not attentive to details when she judges that a study is useful for her paranoid fights!” (…) Fraudulent study. Fake news », wrote in English the French infectiologist, director of the IHU Méditerranée Infection. A little later, Professor Raoult continues, with less virulence: “The study published in pre-print on 04/21 on Medrxiv by Maganoli et al has three major biases which invalidate its conclusions, in any case absurd and incompatible with the literature”
