Environmental pollution refers to the contamination of the environment with harmful substances or pollutants that can have negative impacts on ecosystems, human health, and wildlife. This pollution can come from a variety of sources, including industrial activities, agriculture, transportation, and waste disposal. Specific types of environmental pollution include air pollution, water pollution, soil contamination, and noise pollution. These pollutants can range from toxic chemical substances, such as heavy metals and pesticides, to greenhouse gases and particulate matter. Research in the field of environmental pollution aims to understand the sources, distribution, and effects of pollutants on the environment, as well as develop strategies for mitigating and preventing pollution. This research often involves monitoring pollutant levels in various environmental media, assessing the health risks associated with exposure to pollutants, and evaluating the effectiveness of pollution control measures. Overall, the goal of research in environmental pollution is to protect the environment and human health from the harmful effects of pollution, and to promote sustainable practices that minimize pollution and its impacts.
