“…Early studies documented deposition of polychlorinated biphenyls (PCBs) and DDT compounds in Sweden (Larsson and Okla 1989;Agrell et al 2002) and found that levels in terrestrial biota were correlated with deposition fluxes (Larsson et al 1990). We do know that concentrations of PCBs and dioxins and furans (PCDD/Fs) can be surprisingly elevated in boreal forest streams of northern Sweden (Bergknut et al 2011;Josefsson et al 2011Josefsson et al , 2016. Routine atmospheric monitoring of POPs is now conducted in Arctic regions of Finland (Anttila et al 2016) and Norway (Bohlin-Nizzetto and Aas 2016).…”

“…By contrast, fewer data are available concerning the occurrence and levels of persistent chemicals in aquatic environments of Arctic and subarctic northern Sweden. We do know that concentrations of PCBs and dioxins and furans (PCDD/Fs) can be surprisingly elevated in boreal forest streams of northern Sweden (Bergknut et al 2011;Josefsson et al 2011Josefsson et al , 2016. In the Baltic Sea PCDD/Fs are also found in sediments (Assefa et al 2014) and chlorinated pesticides in water and fish (Nyberg et al 2014;Bidleman et al 2015).…”

We report concentrations of polychlorinated biphenyls, polybrominated diphenyl ethers, novel flame retardants, and naturally occurring bromoanisoles in water and filter-feeding black fly (Simuliidae) larvae in 3 tundra streams in northern Sweden. The results demonstrate that black fly larvae accumulate a wide range of organic contaminants and can be used as bioindicators of water pollution in Arctic streams.

“…Such devices include solid-phase microextraction (SPME) fibers and silicone-coated glass vials [2,[8][9][10]. Moreover, low-density PE [11,12], polyoxymethylene devices [13][14][15], ethylene vinyl acetate films [16], and silicone microtubes [17] have been used for passive sampling. Furthermore, refinements such as thin polymer layers and in vivo sampling of biota have increased the applicability of passive samplers, and new methods have been developed especially for predicting equilibrium partitioning concentrations of hydrophobic organic chemicals in model lipids [2,17,[18][19][20][21][22][23].…”

Equilibrium sampling devices can be applied to study and monitor the exposure and fate of hydrophobic organic chemicals on a thermodynamic basis. They can be used to determine freely dissolved concentrations and chemical activity ratios and to predict equilibrium partitioning concentrations of hydrophobic organic chemicals in biota lipids. The authors' aim was to assess the equilibrium status of polychlorinated biphenyls (PCBs) in a contaminated lake ecosystem and along its discharge course using equilibrium sampling devices for measurements in sediment and water and by also analyzing biota. The authors used equilibrium sampling devices (silicone rubber and polyethylene [PE]) to determine freely dissolved concentrations and chemical activities of PCBs in the water column and sediment porewater and calculated for both phases the corresponding equilibrium concentrations and chemical activities in model lipids. Overall, the studied ecosystem appeared to be in disequilibrium for the studied phases: sediment, water, and biota. Chemical activities of PCBs were higher in sediment than in water, which implies that the sediment functioned as a partitioning source of PCBs and that net diffusion occurred from the sediment to the water column. Measured lipid‐normalized PCB concentrations in biota were generally below equilibrium lipid concentrations relative to the sediment (CLip⇌Sed) or water (CLip⇌W), indicating that PCB levels in the organisms were below the maximum partitioning levels. The present study shows the application versatility of equilibrium sampling devices in the field and facilitates a thermodynamic understanding of exposure and fate of PCBs in a contaminated lake and its discharge course.

“…These chemicals are found in the air (Onofrio et al, 2011), soil (Covaci et al, 2002), oceans and rivers (Josefsson et al, 2011) and in animal tissues (Ying et al, 2002;Jaspers et al, 2006). As a result of lack of strict regulations or proper toxicity tests when these compounds go on the market, the adverse effects of many compounds are discovered only after their widespread use in industry and by consumers (Rudel and Perovich, 2009;Knez, 2013).…”

Effects of 4-Nonylphenol on reproduction of exposed females during puberty

et al. 2016

Abstract4-Nonylphenol (NP) is considered an endocrine disruptor due to its capacity to interact with endocrine system, mimicking estrogen activity. It is a ubiquitous pollutant since it has been found in many human tissue samples and its precursor identified in sewage, sediments, rivers and drinking water. Thus, this work aimed to evaluate reproductive parameters in female Balb/C mice treated with 50 mg/kg body weight of NP for 21 days, a period in which they reach sexual maturity. Body weight during treatment, day of vaginal opening, organs weight, fertility rate and proportion of different follicle types were some of these parameters. Additionally, for analysis of some effect in littermates, a group of animals underwent two attempts at pregnancy after treatment. NP had no effect on body weight during treatment, nor did it alter the day of vaginal opening and fertility rate of females. The proportion of preantral, antral and degenerated ovarian follicles was not modified by treatment with NP, and no morphological or pathological alterations were observed. The number of pups did not differ between treatments in any attempt at pregnancy. Also the weight of pups on birth and female rate in littermates was similar among experimental groups after both trials of pregnancy. It is suggested that the NP available or accumulated during the period of sexual maturation (21 days) did not reach threshold levels capable of producing significant alterations in the reproductive parameters analyzed.
