Toxic Agents

Toxic agents are substances which, when exposed to humans, cause negative health effects. They include microorganisms, chemicals, physical agents, and biological agents. Examples of toxic agents include lead, asbestos, mercury, arsenic, radiation, and certain pesticides. Exposure to these agents can cause a wide range of adverse health effects, from respiratory or skin irritation to cancer. Toxic agents can be found in the environment, such as in polluted air or water, or in workplaces and homes. To reduce the health risks associated with exposure, it is important to reduce the exposure to these agents through the use of protective measures, such as wearing personal protective equipment, or using protective ventilation or filters in a workplace.
