RIVM to Start Extensive Health Study Around Chemelot in 2026
The Dutch National Institute for Public Health and the Environment (RIVM) has announced that a comprehensive health study around the Chemelot chemical industry park in Zuid-Limburg will not begin until the first half of 2026 at the earliest. While the RIVM has started preparations, no concrete health study has yet taken place.
The study aims to address the concerns of local residents regarding potential health impacts from the park’s emissions of hazardous substances. Chemelot is home to around 60 chemical companies, situated between the municipalities of Sittard-Geleen, Stein, and Beek, where approximately 130,000 people reside.
Politicians in Limburg have long been pressing for such a study, with a majority of provincial council members demanding one in November 2023 following reports of incidents at chemical companies on the site. The province had also previously urged the RIVM to conduct a health study after a smaller-scale investigation revealed local residents’ concerns.
However, conducting such a study presents significant challenges. One key issue is that the extent of chemical substances to which residents are exposed is not precisely measured but rather estimated. In April, the Health Council advised establishing a structured monitoring program to address this, including regular blood and urine tests on at least 1,500 people to determine their exposure levels over time—a process known as biomonitoring.
While air, water, and food are monitored for chemical substances, it remains unclear how many of these substances penetrate the human body. By regularly testing a large group of people, regional studies can later be compared with national averages to better assess any additional health risks for local residents.
Another challenge is the vast number of chemical substances produced worldwide, numbering over 100,000. It is not feasible to include all of these in a monitoring program due to financial and technical constraints. A selection must be made, which can be based on both financial considerations and technical feasibility, as not all substances are easily measurable.
The RIVM’s upcoming comprehensive health study aims to provide much-needed clarity regarding the potential health impacts of living near Chemelot, helping to ease the minds of concerned residents and offering valuable insights for local policymaking.
