“…On this basis, analysis of the livers for piglet according to disease type was performed because the liver sample accumulates more dioxin compounds than other organs (Fernandes et al 2010;Conka et al 2012;Rose et al 2012). It is known that due to its detoxification properties, liver gathers toxic compounds in the greater extent when compared with the other internal organs (Shen et al 2012b;Holma-Suutari et al 2016) (Table 3). Five liver samples of each North American-type and European-type PRRSV that cause a disease of pigs were analysed.…”

This study deals with the levels of toxic polychlorinated dibenzo-p-dioxin and furan congeners (PCDD/Fs) in the livers of piglets affected by infectious diseases using isotope dilution high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS). Seventeen toxic congeners in the liver samples infected with bacterial and viral diseases were compared. For porcine reproductive and respiratory syndrome virus (PRRSV) samples, the North American- and European-type PRRS diseases were observed. This study shows that there are significantly different levels of PCDD/Fs, present, which vary according to the types of diseases as evidenced by our analysis of the piglet liver samples.

Reindeer herding is a vitally important agricultural sector in the Russian Far North. It is believed, that Nothern ecosystems are prone to accumulation of persistent pollutants for the reasons of trophical chains, features and climate. Reindeers graze on vast areas, having seasonal migrations on distances up to hundreds kilometers in one side in North-South direction, that increases likehood to cross a locally polluted area. Here we present results of a large-scale countrywide study of reindeer liver, kidneys and meat pollution by dioxins, cadmium and mercury. Samples were taken in 2015-2020 years from 41 locations in 8 reindeer-herding regions of Russia. Dioxins were determined in 383 samples of liver and 13 of meat, cadmium and mercury – in 505 samples of liver, 315 of kidneys and 22 of meat. Dioxin pollution has shown a clear geographical trend: liver concentrations gradually decrease from the Western to the Eastern parts on the country, with the highest concentration of 76.5 pg/g of fat WHO-TEQ. The following factors are likely to explain the discovered trend: localization of chemical enterprises and density of reindeer population. The highest concentrations of metals were found in kidneys (7.3 mg/kg of cadmium and 1.1 mg/kg of mercury). The contribution of local sources to cadmium and mercury pollution was found to be less, than expected. We also speculate, that reindeer liver may serve as a good additional indicator of environmental pollution by the investigated contaminants.

“…Over the past decades, there have been of great concern over the prevalence and environmental fate of some legacy BFRs such as polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs). Due to their persistent, bioaccumulative, toxic, and long-range transportable properties [2][3][4][5][6], Tetra-through Hepta-BDEs, Deca-BDE, and HBCDs had been listed in Annex A of the Stockholm Convention as persistent organic pollutants (POPs) for elimination by 2017 [7]. To meet flammability standards for goods and materials, the usage of alternative or novel brominated flame retardants (NBFRs) has rapidly increased in recent years [8].…”

Background: Novel brominated flame retardants (NBFRs) have been increasingly used as alternatives to legacy BFRs (e.g., PBDEs and HBCDs) in consumer products, but are liable to emigrate and contaminate indoor dust. In this study, a total of 154 house dust samples including floor dust (FD) and elevated surface dust (ESD) were collected in the biggest metropolitan area (Shanghai) of East China in 2016. Limited information about temporal variation of NBFRs indoors is available, while the period of sampling is influential in human exposure estimates. Levels, temporal variation, and human exposure of seven target NBFRs such as decabromodiphenylethane (DBDPE), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), 2-ethylhexyl 2,3,4,5-tetrabromobenzoate (EHTBB), and bis(2-ethylhexyl) tetrabromophthalate (BEHTEBP) were investigated in indoor house dust.Results: Concentrations of ∑ 7 NBFRs ranged from 19.11 to 3099 ng/g with a geomean of 295.1 ng/g in FD, and from 34.74 to 404.6 ng/g with a geomean of 117.9 ng/g in ESD. The geomeans of DBDPE were 219.6 ng/g in FD and 76.89 ng/g in ESD, accounting for 90.5% and 80.5% of ∑ 7 NBFRs. Levels of EHTBB, BTBPE, and DBDPE in FD exceeded significantly those in ESD. The temporal variation in ∑ 7 NBFRs in FD was ranked as summer > winter > autumn > spring. The daily exposure doses (DEDs) of ∑ 7 NBFRs via dust ingestion decreased as: infants > toddlers > children > teenagers > adults. Infants showed the highest DED in FD, 9.1 ng/kg bw/day. Conclusions:DBDPE clearly dominated the NBFRs in both FD and ESD, but the concentrations of DBDPE in this study were generally moderate compared with the other international studies. Dust ingestion was the major pathway of human exposure to NBFRs indoors. About eightfold difference in exposure estimates between infants and adults showed that infants faced elevated exposure risks in FD. This study highlighted the necessity to estimate human exposure of NBFRs for different age groups using FD and ESD, respectively. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
