Looking at toxicodynamic variation in the human population to address chemical safety
The European Food Safety Authority (EFSA) has awarded a €1.6M contract to an LACDR-led consortium to assess how sensitivity to toxicity caused by chemicals varies among individual people. Currently these toxicodynamic differences are an unknown source of uncertainty when carrying out risk assessment…

Webb reveals chemical profile of atmosphere of exoplanet WASP-39 b
An international team of astronomers has revealed the first 'chemical profile' of an exoplanet's atmosphere. The team, including Leiden astronomer Yamila Miguel and provenda Amy Louca, made the profile using so-called Early Release Science data from the James Webb Space Telescope. The results have been…

A cocktail of chemicals in surface water is more toxic than each substance individually
Pesticides can form a toxic cocktail when they occur in combination in surface water. This is the finding of research that Leiden University and the Dutch National Institute for Public Health and the Environment (RIVM) presented on Monday 14 October. The Dutch Ministry of Infrastructure and Water Management…

promises to help farmers cut pesticide use – but could also make chemicals more toxic
Nanotechnology has pervaded numerous industrial sectors over the past decades. Although many of us may not be aware of it, nanomaterials are now embedded within many of the the products we use in our daily lives. The agricultural sector might be next in line. Leiden environmental scientists Tom Nederstigt…
