To reduce lead in the solid waste stream, which source should a solid waste manager target as a major contributor?

Focusing on lead acid batteries as a major contributor to lead in the solid waste stream is vital due to their widespread usage in vehicles and various equipment. Lead acid batteries contain significant amounts of lead, which poses serious environmental and health risks if not managed properly. When these batteries are discarded improperly, they can leach lead and other hazardous materials into soil and water, leading to contamination and health hazards for both ecosystems and communities.

Lead acid batteries are also one of the most recycled products in the world, with a recycling rate over 95%. This means that effective management and targeted recycling programs can greatly mitigate their environmental impact. By emphasizing the reduction and proper recycling of lead acid batteries, solid waste managers can significantly lower the amount of lead introduced into the waste stream and, in turn, reduce potential public health concerns associated with lead exposure.

Other sources, like fluorescent bulbs or household batteries, do contain lead but either in lesser amounts or can be more efficiently managed through existing recycling programs. Leading efforts to target lead acid batteries can yield the most substantial benefits in reducing lead pollution in solid waste systems.
