Over the years, lead use in paint in particular, has declined dramatically as the health and environmental risks have become clear. However, in many countries, lead is still used in paints as pigments, driers, catalysts and for corrosion resistance. This module explains why lead is used in paint, the contribution of different ingredients to the overall content of lead in paint, the different kinds of paint that may contain lead, and why lead paint is a problem.

Lead Exposure and Risk of Adverse Health and Environmental Effects
Lead is a cumulative toxicant that has harmful effects on multiple body systems. It also causes adverse effects on the environment. No safe level of exposure to lead has been identified.
This section is made up of two modules. The first module provides important information on the health hazards and impacts of lead to both an individual and society. The module also provides information on how people can become exposed to lead from paint, the short and long term health effects of lead, and identifies the segments of the population that are particularly vulnerable to exposure and toxicity. The second module describes the environmental impact of lead and its negative effects on other organisms.

Methods for Measuring Lead in Blood and Paint
In order to prevent exposure to lead from paint it is necessary to determine the extent of the problem and then to monitor the success of prevention and control measures.
To help provide an understanding of these issues, this section provides information in two modules. The first module describes how to select the best method for measuring lead concentrations in blood. The second module describes how to carry out a study to determine the lead content in paint and outlines different methods for measuring lead in paint.
