Chromium: Environmental Impact and Biogeochemistry

This lecture covers the environmental impact of chromium, a metal used in various industries, with a focus on its two oxidation states: Cr(III) and Cr(VI). It discusses the toxicity and carcinogenicity of Cr(VI), its presence in tap water, atmospheric transport, and its transformation pathways in different environments. The lecture also explores the detoxification mechanisms, reduction processes, and microbial interactions related to chromium contamination, emphasizing the importance of remediation strategies for groundwater and soil/sediment sites.
