Mutagenicity of an aged gasworks soil during bioslurry treatment
This study investigated changes in the mutagenic activity of organic fractions from soil contaminated with polycyclic aromatic hydrocarbons (PAHs) during pilot-scale bioslurry remediation. Slurry samples were previously analyzed for changes in PAH and polycyclic aromatic compound content, and this study examined the correspondence between the chemical and toxicological metrics. Nonpolar neutral...
متن کاملDetermination of Aroclor 1242 Concentration in an Aged Contaminated Soil
Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants that have attracted great concern in the past few decades. PCBs were first synthesized in 1864 (WHO, 1993) and widely used in the United States between 1929 until their manufacture was banned in 1977 (Erickson, 1986; Nies and Vogel, 1990). Due to the widespread use of PCBs and improper disposal practices, a significant a...
متن کاملSuccession of phenotypic, genotypic, and metabolic community characteristics during in vitro bioslurry treatment of polycyclic aromatic hydrocarbon-contaminated sediments.
Dredged harbor sediment contaminated with polycyclic aromatic hydrocarbons (PAHs) was removed from the Milwaukee Confined Disposal Facility and examined for in situ biodegradative capacity. Molecular techniques were used to determine the successional characteristics of the indigenous microbiota during a 4-month bioslurry evaluation. Ester-linked phospholipid fatty acids (PLFA), multiplex PCR of...
متن کاملGenotoxicity of bioremediated soils from the Reilly Tar site, St. Louis Park, Minnesota.
An in vitro approach was used to measure the genotoxicity of creosote-contaminated soil before and after four bioremediation processes. The soil was taken from the Reilly Tar site, a closed Superfund site in Saint Louis Park, Minnesota. The creosote soil was bioremediated in bioslurry, biopile, compost, and land treatment, which were optimized for effective treatment. Mutagenicity profiles of d...
