A major proportion of metal contaminants in aquatic environments is bound to suspended particulate matter (SPM), yet environmental monitoring typically focuses on dissolved metals, with the filtration step removing SPM. This step may inadvertently hide the potential risks posed by particulate metals. In this study, we used stable isotope tracers to quantify the contributions of SPM-bound metals to the bioaccumulation of nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) in Ruditapes philippinarum, a widely distributed clam crucial to global aquaculture.

Pharmaceuticals and per- and polyfluoroalkyl substances (PFAS) are persistent organic micropollutants (OMPs) posing environmental and health risks due to their bioaccumulative nature and potential toxicity. These OMPs spread to the environment due to the extensive use in today's society. Conventional wastewater treatment plants (WWTPs) are not designed to effectively remove these contaminants, making WWTPs an important pathway, especially for pharmaceuticals, to the aquatic environment.

Pesticides have a significant impact on the environment, harming valuable non-target organisms like bees. Honeybees, in particular, are ideal bioindicators of pesticide exposure due to extensive research on how pesticides affect their behavior, immunity, development, biomolecules, and detoxification. However, wild pollinators are less studied in terms of pesticide exposure, and their inclusion is essential for a comprehensive risk assessment.

Antibiotics and microplastics (MPs) are two classes of emerging contaminants that are commonly found in various water environments. However, how different sized MPs affect the toxicity and biodegradation of antibiotics remains poorly understood. We investigated the effects of polystyrene (PS) MPs with different particle sizes (100 nm and 30 μm) on the physiological responses and degradation behavior of Phaeodactylum tricornutum to sulfamerazine (SMR).

Background: This study investigated the selenium-binding capacity of the biomass of two yeast strains, American Type Culture Collection (ATCC) 7090 and CCY 20-2-26.
Methods: The studies carried out methods of bioaccumulation by yeast biomass. Inorganic selenium was added to the culture media as an aqueous solution of NaSeO at concentrations ranging from 0 to 40 mg Se/L.
