Residue and ecological risk assessment of Polybromine diphenyl ethers (PBDEs) in the surface water of West Lake, Hanoi

Abstract

PBDEs are a group of persistent organic pollutants used as flame retardants in polymeric materials such as plastics, plastics, and rubber. From these materials, PBDEs are found in many consumer products, especially electrical and electronic equipment, household plastic products, furniture, transportation vehicles, and workwear. The toxicity of PBDEs is relatively low, but they have the potential to bioaccumulate and cause negative effects in humans. The main effects include endocrine disorders, affecting the human brain, liver, and kidneys. PBDE can enter the environment by evaporation from plastic products, from dust from electronic waste, from exhaust fumes from municipal solid waste incinerators, and then enter the food chain (accumulation). in food such as fish, beef...) and then into the human body (eating, breathing, skin contact). The concentrations of PBDEs in all biological samples ranged from 2.38 to 1632 ng/g dry weight with an average value of 425 ng/g. They persist in the environment for a long time, are hydrophobic, bioaccumulative and highly contagious. Many studies show that PBDE has accumulated in blood, human milk and environmental components such as air, soil, and sediment in many countries around the world.
