Whales and Dolphins Contaminated by Microplastics

A study has found microplastics embedded in the fats and lungs of whales, dolphins, and other marine mammals, indicating that these particles can move beyond the digestive tract and become embedded in animal tissues. The potential consequences of this are still unknown, but previous research has linked plastics to hormone disruption and other endocrine-related issues. The study analyzed tissue samples from 32 marine mammals and found plastics in all of them, with polyester fibers and polyethylene being the most commonly detected types. The presence of microplastics in these animals raises concerns about their impact on marine ecosystems and potentially human health.
