Anthropogenic Organic Chemicals in Biosolids from Selected Wastewater Treatment Plants in Georgia and South Carolina
The levels of anthropogenic organic chemicals were investigated in biosolids collected from 12 wastewater treatment plants, serving rural, industrial, and urban communities, in Georgia and South Carolina. A variety of anthropogenic organic chemicals were identified and detected in the biosolids at concentrations from mg kg-1 to mg kg-1. 4-nonylphenol (4-NP), a non-naturally occurring endocrine disruptor, is one of the most detected organic chemicals. Its level was detected at as high as 1400 mgkg-1 in several biosolids from urban and industrial areas. Disposal of biosolids to the environment will create a high potential for biosolids-associated organic contaminants to enter into the water environment through leaching and runoff.
