“…[21] reported that the overall mean of Pb and Cd contents in camel milk in Egypt were 1056±105.85 and 8.00±0.21 ppb, respectively. The obtained results agreed with those reported by Saini et al(2007) [22], Meldebekova et al (2008)[23] and El-Bagermi et al (2014)[24]. To the best of our knowledge, there were no previously published data on detection of Hg in camel milk samples.…”

Toxic heavy metals and especially lead (Pb), cadmium (Cd) and mercury (Hg) can easily transmit to humans through consumption of contaminated milk. The present research was done to study the concentrations of Pb, Cd and Hg in different types of milk samples. In total, 1100 bovine, ovine, caprine, buffalo and camel raw milk samples were collected in different regions of Iran and analyzed to determine concentrations of Pb, Cd and Hg by a graphite furnace atomic absorption spectrometric method. The mean recoveries of the analytical method were 88%, 93%, and 96%, for Hg, Cd and Pb, respectively. The mean Cd, Pb and Hg contents obtained from 1100 samples were 3.62±0.35 ppb (range: 0.06-14.03 ppb), 11.73±1.09 ppb (range: 0.12-33.62 ppb) and 4.35±0.42 ppb (range: 1.03-10.38 ppb), respectively. The highest concentrations of Cd, Pb and Hg were found in raw bovine samples (4.05±0.38, 12.36±1.21 and 5.76±0.53 ppb, respectively), while raw camel milk harbored the lowest concentrations of heavy metals. Milk of 5≤ year-old animals had the highest concentrations of Cd, Pb and Hg. Milk samples of all studied animals collected in spring had the highest concentrations of Cd, Pb and Hg heavy metals (P<0.05). The mean concentrations of Cd and Hg heavy metals were lower than the allowed limits announced by the standard organizations, while those of Pb were higher. These results highlight the importance of periodically monitoring levels of Cd, Pb and Hg heavy metals in milk of bovine, ovine, caprine, buffalo and camel-especially in spring and summer seasons and also in 5≤ year-old animals in Iran.

“…Similar trend was observed of zinc concentration in booth milk (Table 2). The present result is closed to that reported by Meldebekova et al (2008) and El-Bagermi et al (2014), who found that the concentration of copper in camel milk was 0.065±0.04 and 0.08 ± 0.05 mg/l, respectively. Similar trend was reported by Alwan et al (2014), who found that concentration of copper and zinc in Farm-reared and Desert-reared Libyan Maghrebi Camels' Milk was 0.58±0.052, 0.24±0.27 and 0.42 ±0.02, 0.14±0.02 mg/kg, respectively.…”

“…Camel milk is used in hot and arid regions as an essential nutritional source, for high energy and vitamins contents (Gorakh et al, 2000 andAl-Awadi andSrikumar, 2001). Camel milk, use as medicinal, dietary properties and used as a fresh milk in some countries (Faye et al, 2008 andMeldebekova et al, 2008). These properties are widely exploited for human health (Kenzhebulat et al 2000 ).…”

The present study aimed to determine concentration of sodium, potassium, copper, zinc, lead and cadmium in camel's milk. The camels was divided into two groups, the first group reared under the traditional farms and the second reared under pasture system. The elements were determined by using atomic absorption (AA) flame spectrometry techniques. The results indicated that the overall mean of sodium and potassium contents in camel milk was 1848.54±571.2 and 3749.90±328.9 mg/l, respectively. While, the overall mean of copper and zinc contents in camel milk was 0.065±0.02 and 0.20±0.06 mg/l, respectively. The overall mean of lead and cadmium contents in milk camel was 1.56±0.85 and 0.008 ± 0.001 mg/l, respectively. Sodium content in pasture camel milk was lower (1823.59±572.7 mg/l) than farm (1873.49±578.03 mg/l), but the content of potassium was higher (3868.49±162 .75 mg/l) in farm than pasture milk (3631.32±411.52 mg/l). Content of copper in pasture milk was higher (0.07±0.02 mg/l) than the farm milk (0.06 ± 0.02 mg/l). Similar trend was observed in zinc content in pasture milk was higher (0.21±0.07 mg/l) than the farm milk (0.19 ± 0.03 mg/l). Lead content was equal in pasture and the farm milk (1.54±1.1 and 1.58 ± 0.45 mg/l, respectively). Cadmium content in pasture milk was higher (0.016± 0.001 mg/l) than the farm milk (0.0005 ± 0.0001 mg/l). The present results of this study indicated that marked differences in concentration of K and Cd between pasture of milk and farm milk.

“…The lead content in milk was positively correlated to the traffic density, (from 0.36 ppm on average for a traffic density of 10 vehicles per day to 7.20 ppm on average for a traffic density of 15000 vehicles per day) [9]. Lead concentration in cow milk was on average of 0.00132 ppm in rural area and of 0.25 ppm in industrial area and 0.032 ppm close a road [10][11][12]. In Germany and Holland, higher value allowed is 0.05 ppm of Pb in milk; 0.02 ppm in Turkey and 0.1 ppm in Kazakhstan.…”

In Kazakhstan, camel breeding mainly occupies areas sometimes close to polluting industries or other sources of pollu- tion as industrial agriculture, mainly cotton. Products issued from camel farms close to these sources as camel raw milk and fermented milk (shubat), wool and meat, traditionally used by humans could be contaminated. We investigated camel raw milk and fermented milk for the content of heavy metals (lead, cadmium, zinc and copper), radionuclide and some organic pollutants (PAHs, pesticides and indicator PCBs) in samples from different regions with a priori high risk of pollution (Atyrau, Kyzylorda, South-Kazakhstan and Almaty region). In the present paper, only some milk samples presented high lead concentration (> 500 ppb). After analysis for organic pollutants, it was observed some traces of hexachlorocyclohexane, lindane, hexanchlorothalonil in milk samples from different regions. One sample was also slightly contaminated with radionuclide. These preliminary results allow establishing a first map of risk for camel farming. As the whole, South-Kazakhstan appeared the most exposed region
