Spatial distribution of Pb, As, Cd contents in Chinese raw milk and risk assessment for human health
Introduction Milk and dairy products contain protein, fat and essential elements necessary for human health, especially for body metabolism, growth and development.However, heavy metals such as Pb, As, and Cd may contaminate raw milk and involve serious systemic health problems when they are in excessive concentration in human body (Oliver, 1997).Milk may contaminant due to local environmental contamination(Kazi et al., 2009).Drinking water contamination is the most important route of As exposure,whereasfood is another source, because agricultural products can accumulate As from contaminated soil and water(Ohno et al., 2007).The objective of this study was first to investigate the spatial distributions of Pb, As and Cd in raw milk in the 10 main milk producing areas in China.Second, the health risk related to the content heavy metals in milk wasevaluated.
