Lead Analysis of Soil Using Atomic Absorption

The analysis of lead and other elements with AAS can be used to answer a variety of questions in environmental science. The fate of other hazardous compounds that are applied to soils, such as fertilizers or pesticides, is not well understood. However, these compounds can pose hazards if they reach water sources through soil runoff.
