“…Additionally, the concentrations of most elements in goat milk were higher than those in cow milk (Table 4), as previously reported [27][28][29]. In the present study, Zn concentration in buffalo milk was five times higher than that in buffalo milk from India, while Fe concentrations were similar between the two studies [30].…”

The objectives of this study were to measure the concentrations of elements in raw milk by inductively coupled plasma-mass spectrometry (ICP-MS) and evaluate differences in element concentrations among animal species and regions of China. Furthermore, drinking water and feed samples were analyzed to investigate whether the element concentrations in raw milk are correlated with those in water and feed. All samples were analyzed by ICP-MS following microwave-assisted acid digestion. The mean recovery of the elements was 98.7 % from milk, 103.7 % from water, and 93.3 % from a certified reference material (cabbage). Principal component analysis results revealed that element concentrations differed among animal species and regions. Correlation analysis showed that trace elements Mn, Fe, Ni, Ga, Se, Sr, Cs, U in water and Co, Ni, Cu, Se, U in feed were significantly correlated with those in milk (p < 0.05). Toxic and potential toxic elements Cr, As, Cd, Tl, Pb in water and Al, Cr, As, Hg, Tl in feed were significantly correlated with those in milk (p < 0.05). Results of correlation analysis revealed that elements in water and feed might contribute to the elements in milk.

“…However, based on the standard deviation observed in this study, we can suggest a higher heterogeneity of milk heavy metal contamination within areas than between areas. This was expected as the contamination of milk by heavy metals is mainly due to contamination of the environment and also the contamination of fodder given to the dairy cows (Mohajeri et al, 2014;Shailaja et al, 2014). For instance, the proximity of lead zinc factories favoured contamination (Mohajeri et al, 2014;Patra et al, 2008;Swarup et al, 2005).…”

“…For instance, calcium, copper, and selenium are essential minerals for normal human body functions, as they are involved in many physiological processes (Alasalvara et al, 2002;Licata et al, 2012). However, heavy metals such as lead (Pb), arsenic (As), and cadmium (Cd) may also be found in milk (Swarup et al, 2005;Shailaja et al, 2014). If they are consumed in excessive concentrations, these heavy metals can lead to serious systemic health problems (Oliver, 1997).…”

“…For instance, Swarup et al (2005) showed that blood Pb levels in lactating cows reared around lead zinc smelting factories were significantly higher than those in non-polluted areas. Shailaja et al (2014) suggested that contaminated fodder given to buffalos might be one factor responsible for elevated Pb levels in blood and milk. The same observations can be made for other heavy metals such as As.…”

This large scale study investigated the spatial variability of Pb, As, and Cd contents in raw milk within and between the 10 main milk producing areas in China. A total of 997 raw milk samples were analysed by inductively coupled plasma mass spectrometry (ICP-MS). Mean values of Pb, As, and Cd in milk were 1.75 μg/L, 0.31 μg/L, and 0.05 μg/L, respectively. The highest level of Pb and As was present in area C, and Cd was highest in area J. The standard deviation suggested a higher heterogeneity of milk heavy metal contamination within area than between areas. Levels of Pb, As, and Cd showed significant differences between studied areas. The estimated root mean squared standardised error obtained by the cross-validation suggested a differentiated quality of Pb, As, and Cd modelling between areas: the predictions obtained were sometimes overestimated or underestimated. These results can be used to define a more appropriate sampling procedure for heavy metal contaminate distribution in raw milk for improved future control of milk contamination by heavy metals in the studied areas. The significant positive correlations between concentrations of Pb-Cd, As-Cd, and Pb-As were observed in nine, six and five areas, respectively. No significant negative correlations were observed. The observed variability of correlation values suggested a different pollution source for Pb, As, and Cd in milk between areas. Further studies are required to clarify the relationships between the contamination of raw milk by heavy metals and the herd environment.

“…Investigation in livestock : A study in 2014 showed about 2.5 times higher Pb in blood and milk samples of lactating buffalos housed in university facility as compared to buffaloes from local shandies13. An inverse correlation between BLL with serum elements (Fe, Zn and Mg) and positive association with creatinine, alanine aminotransferase and ALP was also recorded.…”

The impact of environmental pollution, especially chronic low exposures of heavy metals (Pb, Cd, Hg, As, Cr, etc .) on nutritional status and health of human and livestock, has become a cause of concern. It is established that malnutrition inhibits enzyme system, alters neurotransmitter levels, degenerate myelin, glial and neural elements, lowering of IQ scores as well as impairment of fine and gross motor coordination. Chronic low-level exposure to heavy metals also results in similar type of deformities at sub-clinical level. However, additive impact of undernutrition and adverse effects of heavy metal exposure is emerging as a serious threat to health in developing countries. High blood Pb/Cd levels and low nutrient levels cause subclinical damage of organ system such as haemopoietic, renal, nervous systems in neonates, children, post-partum women, and occupationally exposed population. This could be due to chronic low-level heavy metal exposures and vis-à-vis interaction between pollutants and nutrients. Our studies are focused on the utility of biomarkers for early subclinical detection of haemopoietic and rental toxicity. Lead exposure from non-conventional sources such as toys, pet/glass bottles, etc . suggest long-term investigation. The present review compiles result of studies conducted in this area highlighting the importance of pollution-nutrition interaction. This may facilitate policymakers on developing the strategies to counter the heavy metal exposure of humans/livestock and their consequences.
