Mercury biomagnification rates in aquatic Arctic ecosystems are higher than in lower latitudes, says a new study from Queen's researcher Raphael Lavoie. Mercury is passed along through food webs in ...

Microplastics — tiny pieces of plastic less than five millimetres in size — have been found in marine and freshwater animals ranging from tiny zooplankton to large whales. However, researchers are ...

Anthropogenic contaminants released into the environment routinely accumulate in both lower trophic organisms (for example, bacteria) and higher consumers (for example, humans) 4,5. Although ...

Researchers have produced a groundbreaking study of how nanoparticles are able to biomagnify in a simple microbial food chain. An interdisciplinary team of researchers at UC Santa Barbara has produced ...

Freshwater ecosystems, for example, are often more directly exposed to microplastics and can contain higher concentrations. Microplastics — tiny pieces of plastic less than five millimetres in size — ...

We need to advance our understanding of the effects of microplastics on aquatic ecosystems, especially on small animals at the base of food webs that might be ingesting more of these particles.
