Environmental chemists study the chemical processes occurring in the environment. They analyze pollutants in air, water, and soil to understand their effects on ecosystems and human health. By identifying harmful substances, they help develop strategies to reduce pollution and promote sustainability. These scientists often work with government agencies, non-profit organizations, and private companies. Their research supports regulations and policies aimed at protecting the environment. Environmental chemists also contribute to the development of green technologies, which aim to minimize environmental impact while meeting societal needs.
