A simple general limiting law for the overall decay of organic compounds with global pollution potential
Article Abstract:
The effective decay rate of a chemical in the environment is somewhere between the minimum decay rate in one of its possible compartments and an upper value. If degradation is slower than transport, this upper value is approached as a general limiting law which can be used as a minimal base for the exposure-based assessment of environmental risk. The general limiting law is illustrated using data on DDT and hexachloroethane.

Mechanism of slow desorption of organic compounds from sediments: a study using model sorbents
Article Abstract:
The slow desorption of organic compounds particularly PCBs and chlorobenzenes have been found to be directly related to the presence of organic matter. Results point to the presence of mineral micropores and organic matter as determinant of slow desorption behavior of organic compounds in both soils and sediments. Organic matter or pores coated with organic matter play significant roles in desorption rates.

Historical trends and current inputs of hydrophobic organic compounds in an urban estuary: the sedimentary record
Article Abstract:
Sediment samples taken from Narragansset Bay were analyzed to determine historical trends and current inputs of aliphatic hydrocarbons, polycyclic aromatic hydrocarbons and polychlorinated biphenyls. It was shown that three different distributions dominated historical trends in contaminants. Three different depositional zones which are associated with water depth and degree of human impact were postulated.
