A Study on Heavy Metal Contamination in Workers Handling Electronic Waste in North India
Abstract: Background E-waste contains hazardous substances like leads, cadmium, mercury, and arsenic which can be harmful for informal workers and recyclers. In North India, one finds an informal sector of e-waste workers who work in extremely micro-manageable conditions with lack of order policy and protective equipment. This study explores the processes and cavities of heavy metals as well as assessing the knowledge, safety measures, and health symptoms of the reclaimers. Objectives …

Lead Ion Removal from Water Using Fava Beans Pod-Derived Phytoadsorbents: A Green Approach
Abstract: The contamination of natural ecosystems—particularly water bodies—with harmful chemical substances poses a serious environmental threat on a global scale. Among these contaminants, toxic heavy metals such as lead, arsenic, cadmium, and mercury are especially concerning due to their non-biodegradable nature and ability to accumulate in living organisms. These metals can enter the human body through the food chain, even at trace levels, leading to various severe health issues, including neurological, …
