“…Some previous research (Konuspayeva et al 2011;Meldebekova et al 2009) attributed the high concentrations of some elements in the milk samples to grazing areas near highways teeming with vehicles and affecting the soil and the feeder plants for animals, other studies refers to the responsibility of sewage and agricultural drainage on the soil pollution and the feeder plants (Rahimi, 2013;Gaucheron, 2013). Bhati and Choudhry (1996), Dey and Swarup (1996) and Simsek et al (2000) considered that cattle reared close to manufacturing or roads produced a milk containing significantly higher levels of lead. However, in all these studies, lead concentration in milk was very variable, with higher value between 0.032 ppm and 7.20 ppm (Bhati and Choudhry, 1996;Swarup et al, 2005 ).…”

To know the effect of environmental factors on the contents of some elements in milks of sheep and camel, samples of animal milks, wild plants and their soils were collected from Qassim and Riyadh regions at Kingdom of Saudi Arabia during March -April , 2016. The digested samples were analyzed for element contents( Fe, Mn, Zn, Cu, Co, Ni, Pb and Cd) using atomic absorption spectrophotometry. The results exhibited high concentrations of Ni and Pb in milk samples (Mean concentrations (ppm) for Pb in camel milk samples of Riyadh and Qassim were 0.54 and 0.59, while for sheep milk samples were 0.68 and 0.88, respectively. In respect of Ni, the mean concentrations in camel milk samples of Riyadh and Qassim were 1.51 and 2.1, while for sheep milk samples were 0.80 and 2.21, respectively). Most concentrations of elements in milk samples are correlated with their concentrations in the soil and their plants, this demonstrate the effect of environmental factors on the milk contents. The bioaccumulation factor of the elements in plants were calculated as well as the percentage of extraction of elements in the milk, which contributed to the interpretation of the results. The study recommends the need to take samples periodically for analysis of milk and components in order to preserve the public health of the citizens.

“…In order to assess the quality of milk, milk samples including infant formulas, milk powder, milk from markets, raw milk (unprocessed), human milk and animal milk from various countries such as Canada, Poland, Lithuania, Italy, USA, UK and Nigeria have been extensively studied (Coni et al, 1995;Dabeka, 1989;Dabeka and McKenzie, 1987;Dobrzañski et al, 2005;Hallen et al, 1995;Honda et al, 2003;Ikem et al, 2002;Krelowska-Kulas, 1990;Krelowska-Kulas et al, 1999;Ramonaityte, 2001;Rodriguez et al, 2000;Simsek et al, 2000;Vavilis et al, 1997;Vander-Jagt et al, 2001).…”

Abstract:We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan, and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.

“…Thus, the cadmium concentrations might follow a pattern of double reasoning. On the one hand, the remarkable enrichment of added raw materials such as cocoa (organic: 53.6 µg Kg -1 ; conventional: 18.3 (16.8;23.0 µg Kg -1 ) and to a lesser extent, milk, (conventional: 6.1 (5.5;7.1) µg Kg -1 ) in the infant cereals is obvious as a result of the cadmium intake by the cacao tree from the soil (Dahiya, Karpe, Hegde, & Sharma, 2005;13 Mounicou, Szpunar, Andrey, Blake, & Lobinski, 2003) and the susceptible influence of environmental pollution on raw cow's milk (Dobrzanski, Kolacz, Górecka, Chojnacka, & Bartkowiak, 2005;Simsek, Gültekin, Öksüz, & Kurultay, 2000;Rodriguez-Rodriguez, Delgado-Uretra, & Díaz-Romero, 1999). On the other hand, a dilution phenomenon is noticed in the infant formulations manufactured with added ingredients at high rate (infant formula: 30-35 %, dehydrated fruits: 25 -30, and honey: 2-5 %).…”

Abstract:Lead and cadmium have become highly toxic metallic elements. There is an obvious toxicological impact of these elements on infants since their intestinal absorption is significantly higher than in adults, thus it is desirable to quantify lead and cadmium levels in commonly consumed infant foods. Zeeman background correction, transversely heated graphite furnace atomic absorption spectrometry, was used to determine both the lead and cadmium content of 91 Spanish infant cereals. Cereals were assessed in terms of different types, cereal predominant in formulation and whether it was obtained organically or conventionally. Preliminary analysis revealed a noticeably higher content of lead and cadmium (median, Q1-Q3) in organic cereals (n = 17, Pb: 26.07; Cd: 18.52;.50 µg kg -1 ) in relation to conventional ones (n =74, Pb: 10.78; Cd: 7.12;.77 µg kg -1 ). Three formulations exceeded European lead maximum levels. Added ingredients (milk, cocoa, fruit and honey) to the cereal base provide lead enrichment. For cadmium, this pattern was observed by cereal based on cocoa, but also the raw materials contributed with a dilution phenomenon, decreasing the final cadmium concentration in infant cereal. Apart from several organically produced cereals, lead content showed a narrow variation, where gluten-free cereals provide lower cadmium content than formulations containing gluten. Dietary intakes of both elements were assessed in comparison with the reference intake values proposed by the EFSA Panel on Contaminants in the Food Chain. Organic infant cereals based on honey and cocoa supplied the highest risk intakes of lead and cadmium, respectively. In accordance with the actual state of knowledge on lead and cadmium toxicity and attending to the upper limits calculated from risk intake values set by EFSA, it seems prudent to call for a revision of both heavy metals content regulated by EC to set a maximum guideline values for infant cereal at 55 and 45 µg kg -1 , respectively.
