Substances that accumulate to hazardous levels in living organisms pose environmental and human-health risks, which governments seek to reduce or eliminate. Regulatory authorities identify bioaccumulative substances as hydrophobic, fat-soluble chemicals having high octanol-water partition coefficients (KOW)(≥100,000). Here we show that poorly metabolizable, moderately hydrophobic substances with a KOW between 100 and 100,000, which do not biomagnify (that is, increase in chemical concentration… 

Exploring the partitioning of hydrophobic organic compounds between water, suspended particulate matter and diverse fish species in a German river ecosystem

Background Bioaccumulation of hydrophobic organic compounds (HOCs) along freshwater food chains is a major environmental concern as top predators in food webs are relevant for human consumption. To

Dietary Uptake Patterns Affect Bioaccumulation and Biomagnification of Hydrophobic Organic Compounds in Fish.

This study indicates that in addition to the well-known lipid-water partitioning, the bioaccumulation of HOCs in fish is also a discontinuous kinetic process caused by the fluctuation of Hoc concentration in the gastrointestinal tract as a result of the discrete food ingestion.

Identifying organic chemicals not subject to bioaccumulation in air‐breathing organisms using predicted partitioning and biotransformation properties

A test with a set of more than 1000 diverse organic chemicals confirms the applicability of the prediction methods for a wide range of compounds and the procedure's ability to categorise approximately four fifth of compounds as being of no bioaccumulation concern, suggesting its usefulness to screen large numbers of commercial chemicals to identify those worthy of further scrutiny.

Exposure, Bioaccumulation, Metabolism and Monitoring of Persistent Organic Pollutants in Terrestrial Wildlife

The rates of elimination from body burdens of wildlife are much higher than the much slower rates of environmental degradation; hence, the changes in body burdens better reflect any changes in the bioavailability of POPs.

An arctic terrestrial food-chain bioaccumulation model for persistent organic pollutants.

A model representing the bioaccumulation of persistent organic pollutants (POPs) in arctic terrestrial mammalian food-chains is developed, parametrized, tested, and analyzed and illustrates a strong relationship between biomagnification factors and chemical K(OA) and illustrates the effect of age, sex, and temperature on POPs bio Accumulation.

A thermodynamic-based evaluation of organic chemical accumulation in aquatic organisms.

It is concluded that food chain transfer can result in an increase in concentration with trophic level, and this increase appears to be significant for chemicals with octanol-water partition coefficients greater than about 10/sup 4/.

Influence of chemical and biological factors on trophic transfer of persistent organic pollutants in the northwater polynya marine food web.

Results of this study show the utility of using delta 15N to characterize trophic level andtrophic transfer of POPs but highlight the effects of species and chemical differences on trophIC transfer of Pops that can be overlooked when a single magnification factor is applied to an entire food web.

Bioaccumulation of persistent organic pollutants in lichen-caribou-wolf food chains of Canada's Central and Western Arctic.

Field-collected concentration data and corresponding fugacities of various hydrophobic organic chemicals show that persistent substances including beta-hexachlorocyclohexane and 1,2,4,5-tetrachlorobenzene with a K(OW) <10(5) can substantially biomagnify in lichen-caribou-wolf food chains in Canada's Central and Western Arctic.

Mechanism of Biomagnification in Fish under Laboratory and Field Conditions

A fugacity based model of the gastrointestinal absorption of contaminants is hypothesized and shows that the fugacity of the test chemicals in the gastrointestinal tract (GIT) can increase to levels up to 7−8-fold greater than those in the consumed food.

Concentrations of lipophilic and persistent organochlorines were orders of magnitude higher in homeotherms than in poikilotherms, with the highest food web magnification factors (FWMFs) for cis-chlordane and p,p‘-DDE.

Gastrointestinal magnification : the mechanism of biomagnification and food chain accumulation of organic chemicals

Dietary bioaccumulation experiments with chlorobenzenes, PCBs, and mirex in guppies and goldfish are presented. The results demonstrate that, in the gastrointestinal tract of fish, the fugacity of

The toxicity predictions are very consistent with the available historical data for lake trout population levels in Lake Ontario, stocking programs, and evidence for recent improvement in natural reproduction concomitant with declining levels of persistent bioaccumulative chemicals in sediments and biota.
