Pathways of Various Toxic Materials from Open Landfill Site and Their Assessment

Abstract

Abstract Toxic assessment study of various chemical pollutants plays a vital role towards its long-term environmental impact. Open landfill site carry many toxic pollutants in the water system like, methyl-thiourea; 3,5-dinitro- benzamide; n-trifluoroacetylmorpholine; di-n-ethylhexyl phthalate; ethyl-trans-hex-3-enylester phthalic acid; 2,4,-dimethyl thiazole; anthraquinone 1-amino-4-benzamido and alizarin red S. LC-MS results confirm the presence of these contaminants, many of which may have evolved due to various hydrolysis and photolysis reactions between production and source. This problem becomes quite complex at landfill sites in hilly areas. This study is reporting various primary and secondary pollutants in the river water system as a result of open dumping mismanagement. Pollutants are classified based on their potential sources such as pharmaceutical, herbicide and pesticide (PHP), food packaging and flavouring (FPF) and dye waste.
