A new study from McGill University suggests that some Icelandic killer whales have very high concentrations of PCBs (polychlorinated biphenyls) in their blubber.

Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases.

The air in the United States and Western Europe is much cleaner than even a decade ago. 

A study by the UPV/EHU’s CBET research group and the University of Bordeaux has shown that graphene oxide nanomaterials, alone and combined with polycyclic aromatic hydrocarbons, pose a potential source of toxicity to fish, but at concentrations that are above the currently expected environmental levels.

We live in times when among the most limited and precious resources on Earth are air and water. 

When investigators in the UK recorded the calls of migratory birds called thrushes at night, they found that call rates were up to five times higher over the brightest urban areas compared with darker villages.

BU ecologists say higher sound levels in Boston’s Blue Hills Reservation could disrupt wildlife and human health benefits of nature recreation.

Wherever scientists look, they can spot them: whether in remote mountain lakes, in Arctic sea ice, in the deep-ocean floor or in air samples, even in edible fish – thousands upon thousands of microscopic plastic particles in the micro to millimeter range.

A new focus article in the May issue of Geology summarizes research on plastic waste in marine and sedimentary environments.
