“…For example, the TLVs of Pb in cow’s milk are 0.05, 0.02, and 0.1 mL/L, in Germany and Holland, Turkey, and Russia, respectively [ 26 ]. The concentration of As in milk varies depending on the sampling location [ 27 ].…”

Background and Aim: The quality of food, especially animal-based food, is crucial for human health. However, the quality of milk and other animal products has become an acute cause for concern in Kazakhstan . Technogenic dispersion of heavy metals (HMs) causes adverse effects on living organisms and creates unfavorable conditions for the existence of humans, animals, and plants. The purpose of this study was to analyze the content of several HMs in samples of soil, horse feed (hay, mixed feed, and bran), mare's milk, and manure to assess bioaccumulation and possible adverse effects on the bodies of horses. An additional purpose was to identify areas with acceptable conditions for obtaining environmentally safe horse breeding products in the agricultural zones of the Almaty region, Kazakhstan. Materials and Methods: Samples were obtained from two farms in the Almaty region in 2020 (spring, summer, and autumn). In total, 72 soil samples were analyzed, which were taken from the upper humus horizon to the depth of the arable layer. Eighty-six samples were taken from the feed of horses. Green feed was represented by perennial and annual grasses (alsike clover, Medicago sativa, sweet yellow clover, as well as pea and oat mix). Barley and wheat bran stored in the warehouses of the farm were sampled for the research as feed supplements. The mixed feed comprised components such as maize and sunflower. In addition, 46 samples of mare's milk and 28 samples of horse manure were collected. The HM analysis was performed in the laboratory of the Kazakh-Japanese Innovation Center. The residual amounts of HMs were determined using an absorption spectrometer with a voltammetric analyzer. The content of cadmium (Cd), lead (Pb), mercury (Hg), and arsenic (As) in all the studied samples of soil, feed, mare's milk, and manure did not exceed the threshold limit values (TLVs), suggesting that the intake of these toxic elements into the human body with food was low. Results: The average Cd concentration was in the range of 0.29-0.31 mg/kg in soil samples and in the range of 0.20-0.27 mg/kg in feed samples. In milk, the Cd concentration varied from 0.01 to 0.02 mg/L and was lower in summer and higher in fall. The total average Cd content in horse manure was 0.1844 mg/kg. The concentration of Pb in soil samples ranged from 1.09 to 1.30 mg/kg with the lowest value in spring and the highest in fall. In the feed, the concentration of Pb varied from 0.14 to 0.76 mg/kg and in milk from 0.03 to 0.15 mg/L. The average concentrations of Hg and As in soil samples averaged 0.022 and 0.019 mg/kg, respectively, and were within the TLVs. Conclusion: In the study areas, the calculated transition rates in the soil–feed–milk–manure system revealed that the greatest transition of HMs was observed for Pb and Cd, and a smaller migration was observed for Hg and As. The tendency of accumulation of trace elements continued in the feed.

“…The study reported that arsenic (As) content of milk of dairy cattle was not affected by feeding with EEG. Also, it was reported that As content of milk in the area contaminated with mining land were 0.0184±0.0068 and 0.1664±0.0423 ppm in liquid and lyophilized milk, respectively (Montana et al, 2019). Besides, lactating livestock exposed to high levels of toxic metals (Pb, Sn, Hg, Cd, Zn, As, Cu, and Fe) accumulate these metals in their milk, thus posing a severe health risk for consumers (Ogut et al, 2016) Mangan (Mn) is one of the essential minerals for dairy cattle.…”

“…According to BSN (2011), the maximum toleration of Hg on milk is 0.03 ppm. Also, Hg was not found in any area with a high probability of being highly contaminated due to a mining zone (Montana et al 2019. Therefore, metal concentration in dairy milk tends to increase with the increase in lactating age, which could be the cause of metals' ability to bio-accumulate (Kabir et al, 2017).…”

The growth of several types of grass in the area of mine re-vegetation is rapidly providing an opportunity to be used as forages despite the possibility of heavy metal contamination. The purpose of the study was to evaluate the effect of treatment of different levels of elephant grass (EG) (Pennisetum purpureum) planted at ex-coal mining reclamation on milk productivity and mineral contents of dairy cattle. This study used four lactating (second lactation) dairy cattle using Latin Square Design of 4 (treatments) x 4 (replications). Each period was 21 days consisted of 14 days of preliminary for feed adaptation and 7 days for observation. Treatments were P0 (0% ex-coal mining (EEG)+60% Farmer's EG (FEG)+40% Concentrate), P1 (15% EEG+45% FEG+40% Concentrate), P2 (30% EEG+30% FEG+40% Concentrate), and P3 (60% EEG+0% FEG+40% Concentrate). The study observed variables of feed intake and efficiencies, milk production, milk quality, and mineral contents of milk. Results showed that EEG treatment at different levels did not affect fresh and dry matter intake. The highest fresh and dry matter intake was found in P0 treatment. There was no significant difference in giving EG planted at the ex-coal mining and the farmer's land on the milk production and milk quality. The only significant differences (p<0.05) were found in mineral Fe and Mg contents of milk. The study concluded that giving EG planted at the ex-coal mining area until 60% of forage affected Fe and Mg contents of milk, but they are still in the safe limit.

“…Arsenic is another highly toxic element known since ancient times and is considered a carcinogen [ 13 , 14 ]. It affects systems and organs, including the skin, respiratory, cardiovascular, immune, genitourinary, reproductive, digestive, nervous, erythropoietic, endocrine, hepatic, and renal systems [ 15 ].…”

The bovine milk quality, safety, and security are of great concern mainly due to the dispersion of toxic substances from various anthropogenic activities and poor practices for organophosphates in agriculture use. This study evaluated the potential risk to human health from lead (Pb), cadmium (Cd), and arsenic (As) from the consumption of milk produced in an area of the Central Andes valley near a mini mineral concentrator by estimating the weekly intake (WI), dietary risk quotient (DRC), hazard quotient (THQ), and hazard index (HI) for the Peruvian population aged 2 to 85 years, in three scenarios of milk consumption by age (minimum, average, and maximum). Toxic element quantification was performed by flame atomic absorption spectrometry following standardized procedures. The mean amount ± standard deviation of Pb, Cd, and As in soils was 292±60.90, 3.54±1.58, and 5.60±2.20 mg/kg, the order of importance being Pb>As>Cd. The contents of Pb, Cd, and As in pastures were 23.17±10.02, 0.25±0.57, and 0.06±0.09 mg/kg, being from highest to lowest Pb>Cd>As. The means of Pb, Cd, and As content in 19 milk samples were 0.029±0.022, 0.007±0.006, and 0.010±0.004 mg/kg. Pb and Cd exceeded the maximum permissible limits (MPL), and the As was below the MPL. At all ages and milk consumption levels, the WI for Pb and Cd were below the estimated tolerable intake (TWI). The WI for As in < 19 years was higher than the TWI. The DRC for Pb and Cd at all three milk intake levels and all ages was < 1, and for As, it was > 1 in < 19 years, being the risk group. The TQH and HI for Pb and Cd were also > 1, signifying no health risk, and for As, the values were > 1 in < 11 years. Our results are valuable for preventing adverse health impacts from safe and innocuous milk consumption.
