The environment risk assessment was presented in this paper particularly, the framework of environmental risk assessment on lead-acid batteries was established and methods for analyzing and forecasting the environmental risk of lead-acid batteries were selected.
The work procedure included identifying accident, analyzing risk, pollution forecast and defensive measures. By analysing the environmental risk assessment of lead-acid batteries, the study supplied direction for the preventive measures according to the forecast results of lead-acid batteries.
Ingestion of vegetables and inhalation are the main exposure pathways. In recent years, environmental pollution and public health incidents caused by the recycling of spent lead-acid batteries (LABs) has becoming more frequent, posing potential risk to both the ecological environment and human health.
Lead-acid batteries are the most widely used type of secondary batteries in the world. Every step in the life cycle of lead-acid batteries may have negative impact on the environment, and the assessment of the impact on the environment from production to disposal can provide scientific support for the formulation of effective management policies.
Literature may vary according to geographic region, the energy mix, different times line and different analysis methods. Life Cycle Analysis (LCA) of a Lead Acid Battery made in China by the CML2001Dec07 process reveals that the final assembly and formation stage is the major emission contributing elements Gao et al. .
Table 8 summarises the cradle-to-grave environmental impacts of different types of batteries. The impacts from the lead-acid batteries are considered to be ‘100%’. The results show that lead-acid batteries perform worse than LIB in the climate change impact and resource use (fossils, minerals, and metals).
