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 ...

Previous studies have shown that engineered nanomaterials can be transferred from prey to predator, but the ecological impacts of this are mostly unknown. In particular, it is not known if these ...

A research team confirmed the occurrence of biomagnification of toxic substance TPT compounds along the marine food chain resulted in very high concentrations of TPT in two top predators, the Chinese ...

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 ...

Rachel Carson’s book Silent Spring was a landmark in the development of the modern environmental movement. Her scientific perspective about the effect of pesticides on the natural world sparked ...

Here, a Galápagos penguin is perched on the molten rock of the Isabela Islands. The authors captured this photo during an 2021 expedition to collect microplastics in the Galápagos Marine Reserve.

The concentrations of many historically used, and now widely banned, pesticides and other toxic chemicals—called legacy contaminants—can become magnified in an animal that eats contaminated food; ...

Some compounds are neither recycled by decomposers nor are they released into the atmosphere. Instead, they remain in the ecosystem in virtually unchanged form as they are passed from one organism to ...
