Lead can cause brain damage in children and can damage our kidneys and central nervous system. Lead can enter our drinking water by leaching from landfills, contaminating the clothes of workers at improperly regulated recycling plants, or reach our homes from crushing CRTs in landfill. Significant amounts of lead ions are dissolved from broken lead containing glass, such as the cone glass of cathode ray tubes, when mixed with acid waters that commonly occur in landfills.
About 70% of the heavy metals (including mercury and cadmium) found in landfills come from electronic equipment discards. These heavy metals and other hazardous substances found in electronics can contaminate groundwater and pose other environmental and public health risks.
