Organic Compounds in an Industrial Wastewater: A Case Study of their Environmental Impact

摘要

The biogeochemistry of organic compounds discharged by a specialty chemicals manufacturing plant was assessed. These compounds ranged in concentration up to 50 ppm in the plant's industrial wastewater and 0.2 ppm in its receiving river water, but up to 7000 ppm in river sediments. The wastewater compounds showed a high environmental stability due to their intentional chemical stability. Significant correlations found between n-octanol/water partition coefficient and aqueous solubility and the environmental factor indicate that compounds with a water solubility less than 5000 ppb and a n-octanol/water partition coefficient greater than 100,000 tend to accumulate in the sediments. A compartmentalized model for the transport of Tinuvin P in the river and estuary was developed.
