Abstract

Amongst toxic heavy metals ?Lead? is considered as number one environmental poison affecting all forms of life on earth as this indispensable metal has no known biological role. In the past, environmental contamination of lead was mainly due to industrialization. Currently alternate sources of lead getting in to our biological system in various forms are identified using various analytical techniques based on different principles ranging from GFAAS to DPASV and ICPMS. Authors have looked in to various techniques used in the estimation of inorganic, organic and particulate lead in variety of materials in all kinds of forms which depends upon various factors such as sensitivity, specificity method linearity considering their impact on health. Small variation in the values obtained while using is of great significance in bringing regulations to control and monitor environmental lead analytical techniques used has great significance. While developing National Policies in any country author has found the importance of lead content at PPM or PPB levels in variety of medium which guided appropriate recommendation for the policy making to prevent adverse effect of lead. Since lead is found to bring about DNA aberrations even at a very low of 5 ug/dl of blood, sensitive analytical technology with good quality assurance is required. With constant exposure of biological system to environmental lead cellular modifications are expected as part of adaptation of life to environmental contaminants and hence the future technology depends on the extent to which environmental modification.
