The soluble lead-acid battery is a redox flow cell that uses a single reservoir to store the electrolyte and does not require a microporous separator or membrane, allowing a simpler design and a substantial reduction in cost. In this paper, a transient model for a reversible, lead-acid flow battery incorporating mass and charge transport and surface electrode reactions is developed. The charge–...

BACKGROUND Battery recycling facilities in developing countries can cause community lead exposure. OBJECTIVE To evaluate child lead exposure in a Vietnam battery recycling craft village after efforts to shift home-based recycling outside the village. METHODS This cross-sectional study evaluated 109 children in Dong Mai village, using blood lead level (BLL) measurement, parent interview, and...

Even today, the use of Lead-acid batteries is projected for the next 50 years. On the other hand, the legislative trend concerning human health and the environment makes evident the need for future innovation on recycling technologies. For this reason, the entire world is working, in the short term, in optimizing and adapting technologies, which today we consider BAT (Best Available Technologie...

BACKGROUND Lead poisoning is a common environmental health hazard in developing countries. Incidences of lead poisoning are seen in all age groups, especially in adults working in lead-based industries, where many still remain unaware of the adverse effects of exposure to unusually high levels of lead. METHODS We report the case of an adult battery worker, who initially received symptomatic t...

In this paper, an alternative battery charging control technique based on fuzzy logic for photovoltaic (PV) applications is presented. A PV module is connected to a buck type DC/DC power converter and a microcontroller based unit is used to control the lead acid battery charging voltage. The fuzzy control is used due to the simplicity of implementation, robustness and independence from the comp...

This study was conducted in a battery manufacturing plant where lead was used in the processes of production, to survey the working conditions and safety behaviors, and to measure the airborne lead level contaminated in the workplace and the blood lead level of workers. The survey of working conditions showed that the workers were directly exposed to lead in sections e.g. grid casting, spreadin...

INTRODUCTION Use of lead acid battery (LAB) in Bangladesh has risen with sharp rise of motor vehicles. As result, manufacture of LAB is increasing. Most of the lead used by these industries comes from recycling of LAB. Workers in LAB industry are at risk of exposure lead and thus development of lead toxicity. OBJECTIVE The objective of this study was to measure the blood lead concentration an...

Lead pollution incidents have occurred frequently in mainland China, which has caused many lead poisoning incidents. This paper took a battery recycling factory as the subject, and focused on measuring the blood lead levels of environmental samples and all the children living around the factory, and analyzed the relationship between them. We collected blood samples from the surrounding resident...

OBJECTIVES Assessment of neurophysiological functions in workers with low level exposure to lead and evaluation of the efficacy of bone lead measurements in the prediction of effects of lead. METHODS Exposure to lead of 60 workers from a lead battery battery factory was estimated from historical blood lead measurements and analysis of lead in the tibial and calcaneal bones with x ray fluoresc...
