Abstract: In order to implement the national heavy metal pollution prevention and control plan, it is imperative to establish the management and evaluation methods for intensity access of heavy metals in key industries. The existing problems in the development of the lead-acid battery manufacture in China were briefly reviewed, and the major processes and pollution generation links analyzed. Correlation analysis for lead generation intensities in both wastewater and waste gas was performed based on the statistical analysis software of SPSS. The results showed that two factors including water usage intensity and seven factors with intensity of gas emissions, which were significantly correlated to lead generation intensity in wastewater and waste gas respectively, could be used as indicative factors for lead generation intensity. The findings could provide indirect judgment for industries to promote improvement of production and management for reduction of lead generation intensity. They could also provide new perspectives for study on establishment of evaluation index system of heavy metal generation intensities.
