“…Among mono-ortho DL-PCBs, PCB 118 showed the highest concentration. A similar DL-PCBs profile was found in milk samples collected in Italy [38]. They also found that the mono-ortho congeners were more abundant than the non-ortho ones.…”

BackgroundTo date, despite the facts that pasteurized milk is the most consumed dairy product in Iran and its consumption has increased almost two fold during the last 10 years, no data are available concerning the concentrations of polychlorinated biphenyls (PCBs) in commercial cow milk in Iran market.MethodsThis study designed to determine the levels of PCBs in these products and to assess population exposure to PCBs by estimating the daily intakes. Pasteurized cows’ milk samples (10 brands) were collected from local markets at two different seasons and analyzed using sensitive and reliable methods.ResultsBased on the results all the indicator PCBs were detected and quantified in all of the samples, the mean ± SD concentration for the sum of the six congeners was 18.92 ± 14.36 ng g−1 fat. None of the samples surpassed the provisional value established by the EU of 40 ng g−1 fat. The sum of dioxin-like congeners, expressed as WHO-TEQ was 0.492 pg/g of fat which was considerably lower than the defined limit 3 pg/g fat, set for cow’s milk. Furthermore, a similar DL-PCBs profile as other studies was found for analyzed samples. The results indicated that concentrations of DL-PCBs were very low, and all of milk samples were compliant with EC legislation. In addition, seasonal variations were not observed for DL- and NDL-PCBs levels (p values >0.05).ConclusionsThe estimated dietary intake for target population was 0.06 pg TEQ/kg of body weight/day, much smaller than the amounts declared by the World Health Organization as tolerable daily intake.

“…Milk samples from farms located in Brescia City were used to determine PCDD/Fs and DL-PCBs contamination level by highresolution mass spectrometry (HRMS), and the total WHO-TEQ values were ranged between 1.78-8.16 pg WHO-TEQ/g fat (average: 4.13 pg WHO-TEQ/g fat), respectively. Higher DL-PCBs in the milk may be due to the steel industry, land lls and waste-energy plant and Caffaro factory (produced a higher volume of PCBs) vicinity to study area (Bertocchi et al 2015). PCDD/Fs and DL-PCBs in milk had been measured from 115 milk collecting plants in France.…”

“…PCDD/Fs and PCBs primary source are industrial sectors like metallurgical production, paper production, pesticide manufacturing, etc (Esposito et al 2009, Esposito et al 2010. For example, bovine milk from Northern Italy is highly contaminated by dioxins and PCBs, due to industrialization and agricultural activities (Bertocchi et al 2015). Humans are mainly exposed through diet, almost 90% of human exposure via food.…”

This study showed the distribution of PCDD/Fs and DL-PCBs in bovine milk and ash samples collected from urban and rural areas of south Tamil Nadu and one milk sample from Japan. Around 25 bovine milk samples and 16 ash samples were collected accordingly. The total TEQ for PCDD/Fs and DL-PCBs were ranged from 0.028 to 7.331 pg TEQ/g fat. Some of the districts were 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) area exceed level of PCDD/Fs and DL-PCBs than WHO regulation limits (6 pg-TEQ/g fat). Likewise, BM3, BM8, and BM14 areas showed higher milk contamination by dioxins, which exceed the WHO regulation limit (3pg-TEQ/g fat). Similarly, the total TEQ for PCDD/Fs and DL-PCBs in ash samples was ranged from 0.02 to 1.2 ng TEQ/g. AS3 (1.2 ng-TEQ/g) and AS11 (1.06 ng-TEQ/g) areas showed higher dioxins and DL-PCBs among the samples. This study provides an overview of dioxins and dioxin-related compounds contamination in bovine milk and ash samples. Further, the CALUX assay method validation has simplifies the monitoring of dioxin contamination in the environment.

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.
