Culturally signiﬁcant interventions to prevent lead exposure of battery recyclers are required. Sulfuric acid used in batteries causes skin lesions and could facilitate the recognition of hazards. This study explored whether joint exposure to lead and sulfuric acid can be used in interventionstomanagehazardousworkconditions.Datawerecollectedfrom120 informal workers, and the blood lead level was measured. Predictors of blood lead levels were explored using a tobit model. The median blood lead level was 9.45 µg/dL (Q75-Q25: 48.9 µg/dL); when lead and sulfuric acid exposure occurred, the level increased to 11.44 µg/dL, and when exposure to lead and other substances occurred, the level was 11.50 µg/ dL. Workers are unaware of the risks of obvious and acute silent chronic exposure. Future preventive interventions could confront the economic beneﬁts of battery recycling with the recognition of susceptibility and severity related to lead and sulfuric acid exposure.
