Alkylphenol ethoxylate degradation products in land-applied sewage sludge (biosolids).
Alkylphenol ethoxylates, widely used in commercial and household detergents in the United States, can degrade during the wastewater treatment process to more toxic, estrogenic, and lipophilic compounds. These include octylphenol (OP), nonylphenols (NPs), nonylphenol monoethoxylates (NP1EOs), and nonylphenol diethoxylates (NP2EOs). These compounds have received considerable attention due to thei...
متن کاملApplication of Municipal Sewage Sludge to Forest and Degraded Land
Nearly 8 million dry tons (7 256 000 t) of municipal sewage sludge are produced each year in the USA by the more than 15 000 publicly owned treatment plants and the tonnage is increasing. Municipalities are faced with increasing cost of incineration, decreasing land for and increasing costs of landfills, and environmental concerns over ocean dumping. Under the circumstances, the attractiveness ...
متن کاملCompost, Manure and Sewage Sludge Applied to a Crop Rotation
The disposal of organic wastes specially from urban origin is a very serious problem. The recycling through agriculture is certainly one of the best solutions but it means a thorough control of the composition and doses applied, as well as the response of the crops, in production and quality. In this paper we deal with compost of solid urban residues, sewage sludge, and cow manure as a known re...
متن کاملOrganic Contaminants of Emerging Concern in Land-Applied Sewage Sludge (Biosolids)
H ISTORICALLY, wastewater treatment plants (WWTPs) have acted as a readily identifiable conduit for the environmental introduction of toxic chemicals from industrial and residential discharges and urban runoff. However, technological improvements in wastewater treatment processes since the enactment of the Clean Water Act of 1972 have resulted in greatly improved pollutant removal efficiencies....
متن کاملSewage sludge land application program in West Virginia
Municipal sewage sludge can be used as a fertilizer for crops but may also introduce undesirable metals into the food chain, especially when used on acid minesoils. In this study, sewage sludge from Morgantown, WV was surface applied to two acid minesoils and a neutral undisturbed soil to evaluate sludge application rates on forage production, nutrient loadings, and on heavy metal accumulation ...
