“…However, serum is usually preferred over whole blood due to the minor complexity of the matrix and because it is a more homogenous material (Lino and Silveira, 2006). While several reports on organochlorine contaminants in human tissues (adipose tissue, milk or serum) have been published for other countries Cerrilo et al, 2005;Jaraczewska et al, 2006;Kunisue et al, 2004aKunisue et al, , 2004bLino and da Silveira, 2006;Muñoz-de-Toro et al, 2006;Pauwels et al, 2000;Poon et al, 2005;Sun et al, 2005;Waliszewski et al, 2001), there is insufficient documentation for Ghana, especially for recent years.…”

“…However, they continue to be detected in both biological and environmental samples worldwide because of their persistent and bioaccumulative properties. There is much evidence to show that OCs interact with the endocrine system, resulting in numerous biologic effects that may affect the health of humans and animals (Muñoz-de-Toro et al, 2006). The toxicological effects of OC contaminants create special problems for individuals who are exposed to them.…”

“…Because humans occupy the top position in the trophic levels, they are obviously exposed to a higher level of these contaminants from aquatic and terrestrial food chains and become vulnerable to the toxic effects. Human beings, like other mammals, have lipid-rich tissue that efficiently retains and accumulates lipophilic contaminants (Travis et al, 1988); and they transfer much of the contaminant loads to offspring during nursing, resulting in trans-generational transfer of contaminants (Kanja et al, 1992;Waliszewski et al, 2001;Muñoz-de-Toro et al, 2006). The concentration of fat-soluble contaminants like the OCs is expected to be considerably higher in breast milk than in whole blood because the blood flow to the breast is much more rapid than is the rate of milk secretion (Weisenberg et al, 1985).…”

It has largely been responsible for the "green revolution", i.e. the massive increase in food production obtained from the same surface of land with the help of mineral fertilisers (nitrogen, phosphorus, potassium), more efficient machinery and intensive irrigation. The use of pesticides helped to significantly reduce crop losses and to improve the yield of crops such as corn, maize, vegetables, potatoes and cotton. Notwithstanding the beneficial effects of pesticides, their adverse effects on environmental quality and human health have been well documented worldwide and constitute a major issue that gives rise to concerns at local, regional, national and global scales (Planas et al., 1997; Huber et al., 2000; Kidd et al., 2001; Cerejeira et al., 2003). Residues of pesticides contaminate soils and water, persist in the crops, enter the food chain, and finally are ingested by humans with foodstuffs and water. Furthermore, pesticides can be held responsible for contributing to biodiversity losses and deterioration of natural habitats (Sattler et al., 2006). There have been reported instances of pest resurgence, development of resistance to pesticides, secondary pest outbreaks and destruction of non-target species. Despite the fact that pesticides are also applied in other sectors, agriculture can undoubtedly be seen as the most important source of adverse effects (Hoyer and Kratz, 2001; cited in Sattler et al., 2006).The application of different pesticides varies with the region. For instance, in North Ameri...

“…Due to bioaccumulation and potential toxicity, thus, PBDEs have aroused great concern. Deca-BDE products have still been produced and used widely, although commercial tetra-and octa-BDEs were added to Annex A of the Stockholm Convention PBDEs in 2009 Covaci et al, 2011 Numerous studies have demonstrated that the concentrations of some persistent organic pollutants (POPs), such as polychlorinated biphenyl (PCB), DDT, DDE, increase generally with exposure time or age in biotic tissues (Ronald et al, 1984;Johnson-Restrepo et al, 2005;Munoz-De-Toro et al, 2006;Mcgraw and Waller, 2009;Weijs et al, 2009;Goutner et al, 2011). However, a few of studies have demonstrated that PBDE bioaccumulation seems to increase with age in some biotic tissues (Riget et al, 2006;Kim et al, 2012), whereas some biomonitoring data show no association between PBDEs concentrations and time/age in biotic samples, such as fish (Zhang et al, 2010;Vigano et al, 2011), mammals (Rayne et al, 2004;Muir et al, 2006;Weijs et al, 2009), and humans (Covaci et al, 2008;Harrad and Porter, 2007;Kunisue et al, 2007).…”

h i g h l i g h t sWe conducted a semi-field experiment of ducks in an e-waste recycling site. PPBDEs increased in fat with time, but fluctuated in other tissues with exposure level. High brominated DE levels increased with time but low brominated DE fluctuated in fat. High brominated DEs seem to have longer half-lives than low brominated DEs in fat. a r t i c l e i n f o b s t r a c tTo reveal what degree bioaccumulation of polybrominated diphenyl ethers (PBDEs) depends on exposure time and other factors, we conducted a semi-field experiment for a year (June 2008-June 2009) in a village in an e-waste recycling site in Taizhou, China. Approximately one hundred of juvenile ducks (Anas domestica Linnaeus) were entrusted to a villager. The ducks lived and forged in a PBDE-polluted pond from the late March to the end of November. Fish and mudsnails that were heavily polluted by PBDEs were main food. In cold days (from December to the middle March), the ducks lived in the villager' house, and mainly fed on paddy, which contained lower concentrations of PBDEs than fish and mudsnails. The female ducks were sampled for PBDE analysis every three months. We found that the P PBDE concentrations in duck liver, muscle, lung and brain fluctuated greatly with the changes of exposure levels that were determined by the environment and diets, but the P PBDE concentrations in fat tissue increased successively with time. Congener analysis demonstrated that the successive increase in the P PBDE concentrations with time in fat tissue was due to the successive increase in concentrations, with large fluctuations of low brominated congeners. The results show that PBDE concentrations in liver, muscle, lung and brain tissues heavily depends on exposure levels rather than exposure time. In fat tissue, by contrast, PBDE concentrations (mainly high brominated congeners) slightly depends on exposure levels but heavily depend on time relative to other tissues, implying that high brominated congeners seem to have longer half-lives than low brominated congeners in fat tissue.
