Abstract

Hazardous materials such as used batteries, containing heavy metals, find their way into the solid waste stream, which finally ended to the landfills. In this study, the amount of used batteries in Iran and their heavy metal contents was determined in the batteries entered to Tabriz landfill site. A questionnaire was applied to study the current management condition of used batteries in Tabriz and Ardabil as representative cities to the whole country. Heavy metal content of 15 AA sized batteries was determined by inductively coupled plasma (ICP). Our findings showed that 14.7% of all used batteries in the country were imported from other countries. About 76 and 24% of all batteries analyzed at the landfill site were AA-sized and cellphone batteries, respectively. In the 60% of all studied batteries, the sum of heavy metal content were less than 100 mg/kg. The findings of this study can be a useful reference for global and local policymakers in order to develop effective regulations for using cleaner materials in battery industry and control used batteries from their generation to the end of battery life.
