Bio: Dr. Indika Neluwa-Liyanage is a Medical Officer, Clinical Research Scientist, and Lecturer at the Department of Biochemistry, Faculty of Medical Sciences, University of Sri Jayewardenepura, Sri Lanka. His research focuses on occupational and environmental toxicology, particularly in understanding the biochemical pathways involved in heavy metal toxicity. With a medical background and extensive experience in biochemical research, Dr. Indika has contributed to numerous studies addressing toxicological risk assessment, bioaccumulation, and health impacts of hazardous environmental exposures. He has also collaborated with international research teams to develop mitigation strategies for heavy metal contamination in vulnerable populations. Dr. Indika actively engages in capacity-building efforts, training healthcare professionals and policymakers on public health interventions related to toxic exposure management.

Abstract: This session will provide an in-depth exploration of heavy metals frequently encountered in various industrial environments, including lead, mercury, arsenic, and cadmium. It will discuss their common sources, such as manufacturing processes, mining activities, and the use of industrial materials and chemicals. Key pathways of worker exposure—namely inhalation, dermal absorption, and ingestion—will be highlighted, alongside a focus on occupational roles and industries at the highest risk of exposure. The presentation will also introduce and contextualize the concept of bioaccumulation, emphasizing its critical role in understanding chronic heavy metal toxicity and its long-term implications for worker health and safety. By examining case studies and regulatory guidelines, the session will outline effective preventive strategies and risk mitigation measures aimed at reducing occupational exposure to heavy metals.
