New lead standards are going to require new sampling methods in the environmental industry. Infants and young children were found to be especially sensitive to low levels of lead, which was linked to behavioral problems, learning deficits and lowered IQ. The federal government, including the EPA, took steps to regulate the propagation of lead by phasing out leaded gasoline, and creating standards for lead in paint, drinking water, and solid waste. This primary standard will be used to set limits to protect public health from the adverse effects of airborne lead, while the secondary standard will set limits to protect public welfare, such as damage to crops, animals and buildings. Current technology is not capable of real-time monitoring for lead, so traditional high-volume samplers must be used. Careful planning and research will produce valid, defensible results, while improvements in technology have increased the effectiveness and accuracy of modern high-volume samplers.
