The recycling of used lead acid batteries (ULABs) is an important source of
environmental contamination with lead, leading to human exposures and lead
poisoning. This is particularly the case with informal ULAB recycling, and mass
lead poisonings have resulted. The technical guidelines on ULAB recycling
jointly produced by the Basel Convention and UNEP
(
http://www.basel.int/TheConvention/Publications/TechnicalGuidelines/tabid/2362/Default.aspx )
provide plenty of guidance that can be translated into regulations. These should
include measures to control informal recycling, the establishment of emissions
limits from recycling sites and mechanisms to monitor compliance. They should
also include the need for worker training and exposure monitoring.
