The Bioconcentration and Degradation of Nonylphenol and Nonylphenol Polyethoxylates by Chlorella vulgaris
Nonylphenol polyethoxylates (NPnEOs), a major class of nonionic surfactants, can easily enter into aquatic environments through various pathways due to their wide applications, which leads to the extensive existence of their relative stable metabolites, namely nonylphenol (NP) and mono- to tri-ethoxylates. This study investigated the bioconcentration and degradation of NP and NPnEO oligomers (n...
متن کاملUptake of nonylphenol and nonylphenol ethoxylates by crested wheatgrass.
Nonylphenol (NP) and other hydrophobic biodegradation intermediates of nonylphenol ethoxylate (NPE) surfactants have been identified in wastewater treatment biosolids. These biosolids often are land applied, but little is known regarding the potential uptake of biosolid-derived contaminants by plants. Hydroponic experiments, 11 to 14 weeks in duration, were conducted to examine the uptake and t...
متن کاملDetermination of nonylphenol polyethoxylates in water samples of microbial degradation by second derivative ultraviolet spectrum
Nonylphenol polyethoxylates (NPEOs) is an important kind of nonionic surfactant widely used in the manufacturing and life of human beings. A second derivative ultraviolet spectrum method was established for the determination of the total NPEOs (the average n was 10) in microbial degradation water samples, and the optimal experimental conditions were studied. Water was used as the solvent. The d...
متن کاملInfluence of nonylphenol on the microbial community of lake sediments in microcosms.
In this study the impact of nonylphenol, an estrogenic degradation product of alkylphenol polyethoxylates, on the microbial community structure in contaminated sediments of aquatic microcosms using in situ hybridization with fluorescently labeled oligonucleotides probes was investigated. A positive correlation between nonylphenol concentration and cell numbers of bacteria and microfungi as well...
متن کاملPotential for 4-n-nonylphenol biodegradation in stream sediments.
The potential for in situ biodegradation of 4-nonylphenol (4-NP) was investigated in three hydrologically distinct streams impacted by wastewater treatment plants (WWTPs) in the United States. Microcosms were prepared with sediments from each site and amended with [U-ring-(14)C]4-n-nonylphenol (4-n-NP) as a model test substrate. Microcosms prepared with sediment collected upstream of the WWTP o...
