A total of 75 samples including, 25 samples each of full cream milk powder, skimmed milk powder and infant milk formula collected from Mansoura city, Egypt at the period between April and September 2014 were analyzed for measuring Lead, Chromium and Cadmium levels. Flame Emission Atomic Absorption Spectrophotometer could detect Lead, Chromium and Cadmium by means of 0.05±0.01, 2.70±0.34 and 0.09±0.02 mg/Kg in examined full cream milk powder, 0.03±0.01, 1.98±0.24 and 0.03±0.01 mg/Kg in examined skimmed milk powder and 0.03±0.01, 3.88±0.34 and 0.04±0.003 mg/Kg in examined infant milk formula, respectively. By comparing the concentration of heavy metals present in analyzed samples to their permissible limits, it was noted that most of tested samples contained heavy metals by levels exceeding maximum permissible limits proposed for them, hence milk powder and infant milk formula may carry a potential health hazards for humans which needs a rigorous monitoring program to prevent food contamination by these toxic heavy metals and to ensure that their levels did not exceed the legal limits for human consumption.
Contamination of Cows Milk by Heavy Metal in Egypt
Bulletin of Environmental Contamination and Toxicology, 2012
The present investigation was carried out to assess the residues levels of five metals (Cadmium, Copper, Lead, Iron and Zinc) in cow milk collected from different sites in El-Qaliubiya governorate, Egypt. A total of 100 cow milk samples were collected from twenty cows in each location sites during the morning milking in the period from March to April, 2011. The highest average concentration are those of iron (16.38 lg/g) followed by zinc (10.75 lg/g) and lead (4.404 lg/g), while the lowest mean concentration are 2.836 and 0.288 lg/g for copper and cadmium, respectively. The results showed that most of the milk samples from the different sites containing all the studied metals with concentration higher than those recommended for milk by international dairy federation standard and Codex.
Assessment of Heavy Metals Pollution in Groundwater and Cow’s Milk in Upper Egypt
Assiut Veterinary Medical Journal, 2016
The present work deals with the evaluation of heavy metals pollution in raw cow's milk and groundwater in Upper Egypt. So, a total of 102 milk and ground water samples were collected from three Governorates in Upper Egypt, namely, Assiut, Sohag and Qena. Concentrations of lead (Pb), Cadmium (Cd), Iron (Fe) and Manganese (Mn) in the digested water and milk samples were determined by Buck model 210 VGP atomic absorption spectrophotometer with flame atomization. Our data showed that the average mean of lead, Iron and cadmium in collected water and milk samples were (0.195 ppm and 0.075 ppm), (0.00040 ppm and 0.00026 ppm) and (3.949 ppm and 0.869ppm), respectively. However, we could not detect Manganese either in milk or water samples. Furthermore, Statistical analysis of data showed that there was a significant correlation (p< 0.05) between heavy metal pollution in milk and that of correspondent examined groundwater samples.

Assessment of Lead Residue in Raw Milk Obtained from Regions of Hamadan province in Iran
During April 2011, 48 samples of raw whole milk were collected from milk products factories in different regions of the Hamadan province in western Iran and analyzed by atomic absorption spectroscopy. The mean level of lead content obtained from all samples were lower than the WHO/FAO standard permissible level (mean = 4.8 μg/kg milk SD = 2.2). According to the author`s forecast there were several factors which could affect the residue in raw milk. These factors can be due to the number of automobile, population and number of industrial factories. However, there was no statistically significant relationship among these factors and the amount of lead in the samples. The authors found out that under investigation regions which have the highest residue of lead in the samples there are located on the areas with the most number of metallic mines.
Heavy metals residues and trace elements in milk powder marketed in Dakahlia Governorate
International Food Research Journal
Fifty random milk powder samples were collected from different outlets in Dakahlia Governorate, Egypt and analyzed by Atomic Absorption Spectrophotometer to determine heavy metals residues and trace elements [lead (Pb), Cadmium (Cd), aluminium (Al), iron (Fe), selenium (Se) and manganese (Mn)]. The average concentration of Pb, Cd, Al, Fe, Mn and Se in examined milk powder samples were 0.791; 0.322; 1.57; 20.41; 0.497 and 0.014 ppm, respectively. All examined samples of milk powder had Pb, Cd, Fe, and Mn residues over the permissible limit. At the meanwhile, 96 and 58% of examined samples had Al and Se levels above the permissible limit, respectively. The calculated daily intake of Pb, Cd, Al, Fe, Mn and Se from consumption of 200 ml reconstituted milk powder per day were 158.5; 64.4; 313.4; 4082; 99.4 and 2.8 µg, respectively, which contributed about 31.64; 92.0; 26.12; 85.04; 1.99 and 3.5% from the Acceptable Daily intake of these elements, respectively.

Background: The contamination of food with heavy metals is a significant concern for humans. Among food products, milk and dairy products have received more attention due to their widespread consumption at all ages, particularly among children. The aim of this study is to determine the concentration of lead and cadmium in milk and dairy products in Zanjan. Methods: 132 samples of milk, doogh, yogurt, and cream were collected from Zanjan city during the winter and summer of 2020-2021. The lead and cadmium levels in the samples were quantified using microwave digestion and graffiti furnace atomic absorption spectrophotometry. Results: The average concentrations of lead and cadmium in traditional milk, industrial milk, doogh, full-fat yogurt, low-fat yogurt, and cream samples were 96.
Detection of Heavy Metals Pollution Intypes of Milk Samples in Baghdad Markets
iraq journal of market research and consumer protection, 2020
The levels of lead (pb), copper (cu), cobalt (co) and cadmium (cd) were determined in different kinds of milk and the health risks were evaluated. The mean levels were 0.73±0.21, 0.06±0.01, 0.12±0.01 and 0.14±0.01 ppm for these metals respectively. The levels of pb and cu were found to be insignificant differences (p<0.05), whereas the levels of co and cd, were no significant differences (p>0.05). The dry and liquid kinds of milk were different significantly (p<0.05), whereas the original, was no significant differences (p>0.05). The values for all metals were more than one. The metals pb and cd were detected at highest concentrations in most dry and liquid milk samples.

Health Risk Assessment of Heavy Metals in Goat's Milk for Adults Group in Jijel Province (Algeria)
Zenodo (CERN European Organization for Nuclear Research), 2023
The continuous urbanization and industrialization in many parts of the world and Algeria have led to high levels of heavy metal contamination in the soil, groundwater, and food chain products. Given the importance of milk and dairy products in the human diet, the aim of this study is to estimate the concentration of heavy metals (lead, cadmium, zinc, and copper) in goat's milk and to assess the potential health risks of those metals on adult consumers. To do so, goat milk was collected from three regions (El-Milia, Texenna, and Djimla) of Jijel, Algeria. Three samples were taken from each region and mixed to create a final sample that was pooled from each region. Then, Flame Atomic Absorption Spectrometry (FAAS) was used to determine the concentration of heavy metals. On the other hand, an online survey was carried out to estimate the daily intake of goat milk. The non-carcinogenic and carcinogenic health risk values were calculated. Our experiment demonstrated that the concentration of lead, cadmium, and copper significantly exceed the acceptable limit values; whereas, the zinc concentration was within the acceptable limit. The highest lead concentration was found in the El-milia region (0.42 mg/kg). The concentration gradient of average cadmium is as follows: C Djimla>C El-milia>C Texenna. They range from (0.0359±0.00247) mg/kg, (0.0155±0.00214) mg/kg, (0.00397±0.000742) mg /kg respectively, while the Texenna region has the highest copper concentration. Daily estimated intake (EDI) of all metals did not exceed the limit value. In addition, the target hazard quotient (THQ) of all metals and hazard index (HI) of the mixture of metals were both below the acceptable limit, representing no carcinogenic risk to the residents. Contrariwise, it was found that the carcinogenic risk (CR) for Cd was higher than the acceptable level (1×10 6), as was the cumulative carcinogenic risk for Cd and Pb. This study will be quite helpful for both inhabitants in taking protective measures and government officials in reducing heavy metal contamination.
