Description:

Environmental chemistry is a dynamic and interdisciplinary field that focuses on the chemical processes occurring in the natural environment and how human activities influence these processes. It bridges the gap between chemistry and environmental science, providing essential insight into how substances interact within air, water, soil, and living organisms. Unlike traditional chemistry, which often focuses on isolated reactions in controlled environments, environmental chemistry examines complex systems where multiple variables, both natural and anthropogenic, interact simultaneously. The roots of environmental chemistry trace back to early observations of natural phenomena, but it truly emerged as a distinct discipline in the 20th century in response to growing concerns about pollution, resource depletion, and environmental degradation. Major events, such as the publication of Silent Spring by Rachel Carson and industrial disasters like the Minamata mercury poisoning in Japan, raised public awareness and scientific interest in the environmental impact of chemical pollutants. These events catalyzed a global movement toward understanding and mitigating the harmful effects of chemicals released into the environment. The scope of environmental chemistry is broad and ever-expanding. It encompasses the study of natural chemical cycles such as the carbon, nitrogen, and sulfur cycles, while also investigating the presence and behavior of pollutants like heavy metals, pesticides, plastics, and atmospheric gases. By analyzing these substances, environmental chemists can determine their sources, pathways, transformations, and ultimate fate in the environment. This knowledge is vital for assessing risks, formulating regulations, and developing remediation technologies. Duration - 1h 56m. Author - Doris Grants. Narrator - Terra Hansen.
