In order to evaluate the contamination status of terrestrial biota in Latvia, muscle and liver tissues of red deer (Cervus elaphus), wild boar (Sus scrofa), and moose (Alces alces) were analyzed for the content of polybrominated diphenyl ethers (PBDE), hexabromocyclododecane (HBCD), tetrabromobisphenol A (TBBPA), as well as cadmium and lead. The highest mean concentrations of PBDEs (46.6 pg g(-1) wet weight (w. w.)), cadmium (0.95 mg kg(-1) w. w.), and lead (0.22 mg kg(-1) w. w.) were observed in the tissues of moose, while the wild boar samples contained the highest levels of HBCD, with the mean concentration equal to 264 pg g(-1) w. w. in muscle tissues. Generally low mean concentrations of TBBPA from 0.52 to 4.54 pg g(-1) w. w. were observed. The liver tissue of all analyzed specimens was found to contain higher concentrations of contaminants, compared to muscle tissue. The congener profile of PBDEs in the analyzed tissues indicated that the recently used pentaBDE formulation was a probable source, while components of HBCD, octa-BDE, and deca-BDE technical mixtures are likely to undergo congener-specific or diastereomer-specific bioaccumulation or metabolic degradation. Considering the reports from other regions, it can be concluded that the terrestrial biota in Latvia is less affected by the studied contaminants. (C) 2017 Elsevier B.V. All rights reserved.
