Prevalent environmental challenges are climate change, the biodiversity crisis, and the global scale of environmental pollution. We identified the cell nucleus as a sensitive sensor for bio-effects of pollutants such as mercury and nanoparticles. As a major route of pollutant uptake into organisms is ingestion, we have developed a test system that uses single intestinal cells of the nematode roundwormCaenorhabditis elegans. Microscopic observation of the cell nucleus in reporter worms for the methyltransferase fibrillarin (FIB-1::GFP) revealed nuclear staining patterns that are specific for pollutants such as silica nanoparticles, BULK silica particles, silver nanoparticles, ionic AgNO3, and inorganic mercury (HgCl2). While the underlying molecular mechanisms need further investigation, cultivation of the reporter worms in liquid culture on microtiter plates now enables cost-effective screening of more pollutants and samples from the environment,e.g.,mesocosm analyses. AsC. elegansleads a dual life in the lab and in ecosystems, alteration of nuclear structure and function may likewise explain how environmental pollutants reduce the fitness of wild worms and thus may negatively affect biodiversity.
