Dolphins and whales stranded on beaches in the southeastern United States had high levels of toxins, including mercury and chemicals found in plastic, according to a study published in the journal Frontiers in Marine Science.

Scientists who led the study said the data provides new, troubling information about the impact of pollution on marine mammals — knowledge that could help save vulnerable and declining species.

“Sea snail shells are dissolving as the ocean gets more acidic”


Rising acidity levels in the world’s oceans are disrupting the shell-making abilities of the marine gastropods. According to a new study, the shells of triton shell sea snails are smaller, thinner and less dense in regions where acidity levels are accelerating.

The whale—a juvenile male, nearly 33 feet long (10 meters) and weighing 6 tons—had swallowed all manner of debris at sea, including ropes, nets, plastic bags, and a plastic drum. The buildup likely blocked its digestive system, causing an infection, according to scientists at the El Valle Wildlife Rescue Center in Murcia, Spain.

“Drop in plastic bags littering British seas linked to introduction of 5p charge”

A UK levy of 5p per bag introduced in 2015 has already reduced single-use plastic bags by 85%.


A big drop in plastic bags found in the seas around Britain has been credited to the introduction of charges for plastic bags across Europe.


“Microplastic pollution in oceans is far worse than feared, say scientists”

The work reveals the highest microplastic pollution yet discovered anywhere in the world in a river near Manchester in the UK. It also shows that the major floods in the area in 2015-16 flushed more than 40bn pieces of microplastic into the sea.

“Microplastics pollute most remote and uncharted areas of the ocean”
