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.
