Is lead-acid battery smelting pollution serious

Secondary smelting of lead is similar to primary smelting, but does not require the initial sintering process. Once lead is recovered from used materials – with the majority coming form used lead-acid batteries – it is placed into a furnace where it is heated with coke or charcoal in order to isolate the lead from other compounds. Like ...

What are the risks of lead smelting for people?

The risks of lead smelting include exposure to lead through inhalation or ingestion of lead dust, particles, or exhaust from the burning process. Workers in lead smelting factories are particularly at risk, as they can be exposed to prolonged and direct inhalation of gaseous emissions and dust.

How dangerous is lead-acid battery?

According to the 2015 report on lead-acid battery by Chinese Association of Battery Industry (Zhao and Cao, 2015-11-24), disposal of lead-containing acid increases significantly by year in the past 12 years and it only starts to decrease from recently (Fig. 1 b). Lead is of highly toxic, poisoning almost every organ through blood.

How does recycling lead-acid batteries affect the environment?

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.

What is secondary lead smelting?

Secondary lead smelting refers to the processing of used lead (like batteries) to extract new lead. If the plants and equipment for this process are not properly constructed to minimize the release of pollutants, lead toxins can often enter the surrounding environment and contaminate soil, water, and food.

Are lead batteries safe to recycle?
