Evaluation of environmental lead exposure in snails from four contaminated sites at abandoned battery factory in Niger Delta, Nigeria

The evaluation of environmental lead exposure in snails from four contaminated sites of entrance, storage, dried effluent and waste dump respectively, at abandoned battery factory (Niger Delta, Nigeria) were investigated Results indicated significant (P<0.05) depressed weights of foot, shell, and offal at elevated lead contamination. The exposure of Achatina achatina snail to lead pollution indicates a pollution warning signal. Contaminated snails are critical pathway for transport of lead along the food chain.

Cobalt investments will struggle to meet longer demand

Significance Prices peaked at USD94,000 per tonne in March 2018 but fell below USD36,000 by January 2019, a level where they have largely stayed, as changes in battery technology and disappointing electric vehicle (EV) sales depressed demand. Mining companies are seeking to diversify supply globally. Impacts Exploration budgets have fallen by at least 10% from 2019, signposting slower replacement of reserves. Revolutionising secondary supply, 135-240 kilogrammes of cobalt may be extractable from a tonne of used mobile phone batteries. Indonesia’s production costs are 8% lower than China’s; it intends to leverage its mineral wealth to become an EV and battery factory hub.

Compound health risk assessment of cumulative heavy metal exposure: a case study of a village near a battery factory in Henan Province, China

The concentrations of the heavy metals Hg, As, Ni, Pb, Cd, Cr, Cu and Zn in soil, groundwater, air, and locally produced grain (wheat and corn) and vegetables were determined in a village near a battery factory in Xinxiang, Henan Province, China.

Energy planning and management during battery manufacturing

The aim of this study is to improve energy performance at a battery factory in Colombia by introducing the energy management approach defined in ISO 50001. In the study, the main energy consumptions were identified in the battery formation, the compressed air system and the large electric motors. An energy review was performed in the factory using measurement equipment and statistical techniques. Different actions were proposed to improve energy performance. As a result, a 3.48% reduction in electricity consumption was achieved during the implementation of the proposed measures.
