Researchers have discovered that hooded seal mothers are inadvertently passing on environmental pollutants to their newborn offspring. The toxins are transferred through the placenta and the mother’s milk. The details are in a paper that was just published in the journal Environmental Toxicology and Chemistry.
(From Natural Science News / by Joanna Lawrence)– Perfluoroalkyl substances (PFASs) are common environmental contaminants that are only just now being properly studied. Many of these chemicals have been banned but some are still used in carpets, textiles, packaging, and other products. They persist in the environment and can be toxic to the native wildlife. PFASs and similar chemicals frequently end up in the systems of marine organisms. Predators such as marine mammals are especially at risk because they eat contaminated prey, resulting in a build-up of chemicals in their bodies. Read the full story »
