  • Toxic by-products of ballast water treatment evaluated

    A new study has evaluated disinfection by-products (DBPs) formed during the treatment of ballast water. As some of the DBPs produced are hazardous, the study concludes that more information is needed to ensure DBPs from treatment methods do not harm human health or aquatic environments. Ships hold ballast water in tanks to provide stability at sea. Frequently, water is taken at one port ...

  • Toxic PBDEs Found in Offices According to New Research

    Polybrominated diphenyl ethers (PBDEs) are flame-retardant chemicals that are added to plastics and foam products to make them difficult to burn. PBDEs exist as mixtures of similar chemicals called congeners. Because they are mixed into plastics and foams rather than bound to them, PBDEs can leave the products that contain them and enter the environment.   There are different kinds of PBDEs; ...
