Researchers studied over a decade of photographic records of individual whales and determined that belugas in Alaska's Cook Inlet have relatively low rates of birth and survival, which are both likely contributing to the population’s decline.
The beluga whale population in Alaska’s Cook Inlet, which connects Anchorage to the North Pacific Ocean, is listed as endangered and has declined by over 75% from about 1,300 whales in the late 1970’s to fewer than 300 today.
Funding to maintain RCRA regulations has been flat or reduced for more than 20 years and EPA is currently reviewing more than 10 other petitions involving the RCRA, EPA notes.
Leachate is generated from the decomposition of waste and precipitation coming into contact with the landfilled material. The water leaches out chemicals from the waste, including Per and Polyfluoroalkyl Substances (PFAS).
The production of these reactive oxygen species from nanoplastics can endanger marine life and human health and potentially affects the mobility of the nanoplastics in the environment via redox reactions.
Researchers investigate PFAS levels in Sarasota Bay dolphins, who like humans, eat fish contaminated by plastic. Here's how their NIEHS project is progressing.
