Lead Exposure Control for Informal Battery and E-Waste Recycling: A Computed Baseline and a Priced Process Change Set
Year: 2026
Type: preprint
Abstract: Model of a small informal workshop breaking lead-acid batteries and dismantling e-waste dry, with a designed process change set (wet breaking, bench local exhaust ventilation, layout separation, handwash and wet housekeeping). SIMULATED, NOT MEASURED; nothing was built, visited, or field-tested. The computed worker 8-hour lead exposure is 1506.3 micrograms per cubic metre (30.1 times the OSHA limit); the full change set reduces it by 96.0 percent for $2750 capital cost, but the residual of 61.0 micrograms per cubic metre still exceeds occupational limits, and a child beside soil contaminated for one year still receives a modelled 406.4 micrograms per day, so respiratory protection, child exclusion, and legacy-soil action are also required.
