Intervención ambiental en sitios contaminados por plomo: La experiencia en los Estados Unidos de América

Abstract

For a decade, state and federal agencies have worked jointly with communities throughout the USA, with the objective of measuring the health-risk from lead pollution in residential zones. Often these communities have been linked with facilities previously associated with activities like mining and metallurgy; nevertheless, there are other industries like paint manufacturing and battery recycling, that have also been identified as lead pollution sources. The vast experience in cleaning up the contaminated sites has shown that ample programs designed to identify and handle the exposure routes can help, in an effective manner, to diminish blood lead levels (BLL) in susceptible populations, such as in young children. Environmental intervention programs are more effective when the affected communities carry out health education/intervention programs, geared towards the development of individualized strategies for handling the risk implied by the presence of lead in the atmosphere.
