Effects of Halogenated Hydrocarbons on Rumen Microorganisms

, 1989
Halogenated hydrocarbons such as polychlorinated biphenyls (PCB's), heptachlor (HEP), 1, 1, 1,-trichloro-2, 2-bis(p-chlorophenyl)-ethane (DDT), and pentachlorophenol (PCP) are environmental contaminants and, at times, can bioaccumulate in the food chain.

Self-cleaning liner for halogenated hydrocarbon control in landfill leachate

, 2017
Sorptive landfill liners can prevent the migration of the leachate pollutants. However, their sorption ability will decrease over time. A method should be developed to maintain the sorption ability of landfill liners.
