“…The established lipophilic properties of PBDEs [2] have been previously used to explain the accumulation of PBDEs in fish tissues, corresponding to their lipid content [45]. However, in our study, only the concentrations of BDE 183 exhibited a medium-strong correlation (Table 5) with the lipid content of fish tissues (Pearson's r = 0.46, p = 0.1803).…”

Abstract:The polybrominated diphenyl ethers (PBDEs) are bioaccumulative, persistent, and toxic. They have a high risk of emission into the environment via volatile losses and diffuse sources, such as commercial product disposal or the use of sewage sludge. The PBDEs' congeners were analyzed in municipal waste water treatment plant (WWTP) sludge, river and lake water, sediment, and fish samples, to investigate the concentrations in urban and natural locations. The sum of eight PBDE congener (∑ 8 PBDE 28,47, 99, 100, 153, 154, 183, 209) concentrations in WWTP sludge varied from 78 ng·g −1 DW, to 714 ng·g −1 DW. The BDE 209 constituted up to 93%-98% of ∑ 8 PBDE. In water, the concentrations of all of the measured PBDE congeners were below the limit of detection. Similarly, the concentration of BDE 209 in the sediments was below the limit of detection in all samples. The sum of seven PBDE congener concentrations in the sediments varied from 0.01 to 0.13 ng·g −1 DW. The sum of eight PBDE congener concentrations in fish (European perch) tissues varied from 0.13 to 0.82 ng·g −1 WW. As was recorded for the WWTP sludge, the BDE 209 was the dominant congener, constituting 24%-93% of ∑ 8 PBDE. The sum of seven PBDE congener concentrations, excluding BDE 209, as well as the concentrations of BDE 209 that were measured in WWTP sludge, exhibited a weak negative correlation (Pearson's r = −0.56, p = 0.1509 and r = −0.48, p = 0.2256, respectively) with the content of dry matter in the sludge. The sum of seven PBDE congener concentrations measured in sediments exhibited a strong negative correlation (Pearson's r = −0.82, p = 0.0006) with the content of dry matter in the sediments, and a strong positive correlation (Pearson's r = 0.68, p = 0.0109) with the total carbon content. The obtained results indicated that the fine-grained WWTP sludge particles, with a larger relative surface area, adsorbed BDE 209 the most effectively. This finding was supported by the relatively low environmental concentrations of PBDE congeners, especially BDE 209, which can be explained by the lack of using sewage sludge in agricultural application in Latvia. Furthermore, it seems that, at present, the observed differences in the PBDE congener concentrations in sediments can be attributed to differences in the physical-chemical properties of sediments.

“…In this sense, Ondarza et al (2014) found that OC and other organic pollutants are ubiquitous contaminants in Patagonian fish tissues in Negro River in the Valle region. However, OC were also found in brown trout (Salmo trutta) in the Andean Patagonia closer to the Bariloche area (Ondarza et al,2011). In view of these results, as a precautionary principle, it may be useful to carry out detailed study on OC concentrations in fish and dumps from the Bariloche area due to the potential risk to wildlife and human health.…”

“…The first pan-European inventory of contaminant monitoring using raptors has shown that there is an existing monitoring capability across Europe (Gómez-Ramírez et al, 2014). However, there are few studies on environmental contaminants in raptors from South America (Ondarza et al, 2011;Saggese et al,2009;Villaamil Lepori et al, 2013).…”
