The Sorption of Hydrophobic Organic Chemicals to Bacteria Tamara Lunsman Re: Final Report for CEQI Proposal Reference Number: 01 T CEQI 08 1073 Sorption of Hydrophobic Organic Chemicals to Coastal Sediment Bacteria and Biofilms
The toxicity and time-dependent sorption of three hydrophobic organic chemicals to Rhodococcus rhodochrous bacteria were investigated. In experiments, environmentally relevant concentrations of pentachlorophenol (PCP), hexachlorobenzene (HCB), and dichlorobiphenyl (DPCB) were applied to living (both growing and nongrowing) bacteria as well as to dead bacteria. For PCP (an ionizing chemical), ba...
متن کاملSorption of organic chemicals to soil organic matter: influence of soil variability and pH dependence.
For modeling the sorption of organic compounds in soils it is typically assumed that the organic carbon/water partitioning coefficient (Koc) of neutral organic chemicals can be treated as a constant property that remains unaffected by the type of soil organic matter as well as pH in the soil solution. Here the validity of these assumptions is evaluated with a large and diverse experimental data...
متن کاملSorption kinetics of hydrophobic organic compounds to natural sediments and soils.
Sorption kinetics of hydrophobic organic chemicals to and from suspended sediment and soil particles is described by a radial diffusive penetration model modified by a retardation factor reflecting microscale partitioning of the sorbate between intraaggregate pore fluids and the solids making up the aggregate grains. In light of this and other sorption kinetics models, a closed-loop-stripping a...
متن کاملSorption of hydrophobic organic compounds (HOCs) to inorganic surfaces in aqueous solutions Dissertation
Sorption of hydrophobic organic compounds (HOCs) to hydrophilic inorganic surfaces in aqueous systems is an important process, because HOCs are common contaminants and the sorption controls their concentration and rate of transport in the environment. Furthermore, in environmental chemistry and analysis, sorption of HOCs to inorganic surfaces, in particular to untreated (uncoated) glass surface...
متن کاملSorption of Hydrophobic Pollutants on Natural Sediments
Ahtract--The sorption of hydrophobic compounds (aromatic hydrocarbons and chlorinated hydrocarbons) spanning a concentration range in water solubility from 500 parts per trillion (ppt) to 1800 parts per million (ppm) on local (North Georgia) pond and river sediments was investigated. The sorption isotherms were linear over a broad range of aqueous phase pollutant concentrations. The linear part...
