“…In such case, raw milk collected from 9 regions of South Korea showed PCDD/Fs and DL-PCBs concentration ranged between 0.05-0.56 pg TEQ/g fat (average concentration-0.27 pg TEQ/g fat) and 0.15-0.40 pg TEQ/g fat (average concentration-0.33 pg TEQ/g fat). In this, concentration of DL-PCBs had been higher than PCDD/Fs and PCDFs concentration was highly contribute to the total PCDD/Fs concentration than that of PCDDs in milk samples (Kim, Kim, Jang, Bong, & Kim, 2013). Further, PCDFs level in 2008 was considerably lower than reported in 2005.…”

This study found distribution of polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans (PCDD/Fs) and dioxin like polychlorinated biphenyls (DL-PCBs) in bovine milk and ash samples collected from 9 different major districts namely Erode, Salem, Namakkal, Coimbatore, Trippur, Madurai, Chennai, Dindigul and Tiruchirappalli, which were highly populated and industrialized districts of South India (Tamil Nadu). The total toxic equivalency (TEQ) for PCDD/Fs and DL-PCBs in the bovine milk samples were ranged from 0.028 to 7.331-pg TEQ/g fat. Some of the districts showed higher PCDD/Fs and DL-PCBs concentration in milk and ash samples. Further, BM14 (7.331 pg-TEQ/g fat) and BM21 (6.406 pg-TEQ/g fat) sampling sites showed exceed level of PCDD/Fs and DL-PCBs than WHO regulation limits (6 pg-TEQ/g fat). Similarly, Total dioxins and DL-PCBs concentration in the ash sample were between 0.003-1. ng TEQ/g. Samples from AS3 (1.2 ng-TEQ/g) and AS11 (1.06 ng-TEQ/g) showed higher total dioxins and DL-PCBs level among other sampling sites. This study provides an overview of dioxins and dioxin-related compounds contamination in bovine milk and ash samples in south Tamil Nadu. Further, the CALUX assay method validation has simplified the monitoring of dioxin contamination in the environment.

“…The different foods represented fruit-, vegetable-, meat/vegetable-and dairy-based foods. This selection was chosen to represent foods which may potentially have high (meat, fish and dairy/egg) and low (fruit and vegetable) concentrations of POPs based on that found in market basket studies (Domingo 2012;Kim et al 2013;Mihats et al 2015;Perello et al 2015). Both organic (n=10) and conventional (n=23) foods were purchased.…”

Persistent organic pollutants (POPs) including polybrominated diphenyl ethers (PBDEs); organochlorine pesticides (OCPs); and polychlorinated biphenyls (PCBs) persist in the environment, bioaccumulate, and pose a risk of causing adverse human health effects. Typically, exposure assessments undertaken by modeling existing intake data underestimate the concentrations of these chemicals in infants. This study

“…Since these toxic compounds are highly lipophilic, milk has been thought to be a prominent source of exposure for humans (Kim et al, 2008; O’Donovan et al, 2011). Many countries have analyzed bovine milk made within its borders for PCB and PBDE content and have found a multitude of congeners at quantifiable amounts (Focant et al, 2003; Durand et al, 2008; Kim et al, 2013; Lake et al, 2013). To date, there has only been one study within the United States (U.S.) looking at a small subset of PCBs in milk samples collected across the country (Schaum et al, 2003), not allowing for any region specific conclusions on PCB content or detection of PBDEs.…”

Polychlorinated biphenyl and polybrominated diphenyl ether profiles in serum from cattle, sheep, and goats across California

It has been previously been shown by our lab and others that persistent organic pollutants, such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), are contaminants in milk produced for human consumption. To further this research we determined the concentration of 21 PCB and 14 PBDE congeners in livestock serum, mainly bovine, across California. Congeners were extracted from serum using solid phase extraction (SPE), cleaned up by silica cartridge and quantified using gas chromatography-triple quadruple mass spectrometry. We detected significant differences among species and the production class of cattle (beef or dairy). The sum of all 21 PCB congeners (ΣPCBs) in caprine and ovine sera had a mean value of 9.26 and 9.13 ng/mL, respectively, compared to 3.98 ng/mL in bovine sera. The mean value for the sum of all 14 PBDE congeners (ΣPBDEs) in caprine and ovine sera was 2.82 and 2.39 ng/mL, respectively, compared to 0.91 ng/mL in bovine sera. Mean ΣPCBs in dairy cattle was 5.92 ng/mL compared to 2.70 ng/mL in beef cattle. Mean ΣPBDEs in dairy cattle was 1.33 ng/mL compared to 0.70 ng/mL in beef cattle. There were no regional differences in the ΣPCBs or ΣPBDEs in cattle distributed across California. These results highlight the fact that livestock are still being exposed to these pollutants yet little is known about where this exposure may be coming from.
