Bioaccumulation of contaminants in fish
1998The term bioaccumulation is defined as uptake, storage, and accumulation of organic and inorganic contaminants by organisms from their environment. Bioaccumulation therefore results from complex interactions between various routes of uptake, excretion, passive release, and metabolization.

Influence of diet on the bioaccumulation of PCBs
Science of The Total Environment, 1993The levels of several chlorinated biphenyls (PCBs) congeners were analysed in muscle of flounder (Platichthys flesus), which were kept in semi-field condition for 1 month. The influence of resuspended sediments and two diets (worms and shrimps) on PCB accumulation in these fish was tested.

Stochastic Models of Bioaccumulation
2020This chapter reviews the theoretical basis and practical application of both the deterministic and the Markov process models. It outlines a basic mechanistic structure relating to uptake and elimination, and their assumptions yield a mathematical model which fits the data adequately.

Bioaccumulation of pentachlorophenol by killifish ( )
Chemosphere, 1982Abstract Killifish ( Fundulus similis ) were exposed in the laboratory to pentachlorophenol (PCP) at concentrations of 57 to 610 μg PCP/L. Bioaccumulation reached a plateau value of about 53 by 168 hrs and remained at this level for at least 72 hrs. One-half the plateau value was reached in about 25 hrs.

Bioaccumulation of heavy metals in Spartina
Functional Plant Biology, 2013The Spartina Schreb. genus is composed of C4 perennial grasses in the family Poaceae. They are native to the coasts of the Atlantic Ocean in western and southern Europe, north-west and southern Africa, the Americas and the southern Atlantic Ocean islands. Most species are salt tolerant and colonise coastal or inland saltmarshes.

Bioaccumulation of copper by Trichoderma viride
Bioresource Technology, 2006Studies were carried out on interaction of Trichoderma viride with copper and reports bioaccumulation as a mechanism of copper tolerance during growth. There was a marked increase in the lag phase of the growth, which was concentration dependent. At a concentration of 100 mg/L of CuCl2.2H2O, 81% of Cu(II) were removed by 3.4 g/L of the biomass in 72 h.

Mercury Bioaccumulation in a Stream Network
Environmental Science & Technology, 2009Mercury (Hg) contamination is common in stream and river ecosystems, but factors mediating Hg cycling in the flowing waters are much less understood than inthe lakes and wetlands. In this study, we examined the spatial patterns of methylmercury (MeHg) concentrations in the dominant groups of aquatic insect larvae across a network of streams (drainage ...

Publisher Summary Discharge of large volumes of treated produced water to coastal and offshore waters results in an increase in the concentrations in the receiving waters of those chemicals that are present in the produced water at concentrations much higher than their concentrations in the ambient seawater.

Composite Sampling and Bioaccumulation
2010The human body, or any living organism for that matter, when exposed to a polluted environment, accumulates contaminants in its tissue. It is, therefore, very useful to sample tissue from a sample of such organisms under investigation, in order to evaluate the amount of accumulation, called bioaccumulation, since biological processes cause the ...
