The farming of livestock to feed the global appetite for animal products greatly contributes to global warming. 

Scientists have got up close and personal with human sewage to determine how best to measure hidden and potentially dangerous plastics.

Modern-day agriculture faces two major dilemmas: how to produce enough food to feed the growing human population and how to minimize environmental damage associated with intensive agriculture. 

Researchers at the University of New Hampshire have conducted two of the first studies in New England to collectively show that toxic man-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up in the environment differently after being processed through wastewater treatment facilities—making it more challenging to set acceptable screening levels.

In cities, heavy rains wash away the gunk collecting on sidewalks and roads, picking up all kinds of debris. 

For two weeks in June 2020, a massive dust plume from Saharan Africa crept westward across the Atlantic, blanketing the Caribbean and Gulf Coast states in the U.S. 

USC researchers modeled complex subsurface water flow to help assess the risk of contaminants appearing in high, unsafe concentrations in variable water source.

New research shows that concentrations of the toxic element mercury in rivers and fjords connected to the Greenland Ice Sheet are comparable to rivers in industrial China, an unexpected finding that is raising questions about the effects of glacial melting in an area that is a major exporter of seafood.

Because of anthropogenic emissions of oxides of nitrogen (NOx), the NOx deposition rate is about five-fold greater than that of pre-industrial times largely due to energy production and biomass burning.

More than 100 kg of highly toxic uranium (U) and plutonium (Pu) was dispersed in the form of tiny ‘hot’ radioactive particles after the British detonated nine atomic bombs in remote areas of South Australia, including Maralinga.
