Assessing the Ability of Marine Plastic Waste to Adsorb Heavy Metals and Emerging Organic Contaminants from Water
Plastic waste has been identified as an increasing threat to the marine ecosystem. One of the most concerning aspects of plastics in the marine environment is their ability to bind contaminants and act as vector for their long-range transport. This may include established and emerging contaminants …
