Air Contaminant是指空气污染物质，大多数这类污染物是人类活动所造成的，其中油烟、尘土、化学物质、农药、放射性材料和微生物等都属于空气污染物。

Air contaminants such as exhaust fumes, dust particles, chemical substances, pesticides, radioactive materials, and microorganisms are released into the air by human activities. Air contaminants can cause harm to people, animals, and the environment.

Air contaminants can also be natural substances such as pollen, spores, and dust. Natural sources of air contaminants are less likely to cause harm to human health.

Exposure to air contaminants can cause a variety of health problems including respiratory infections, asthma, allergies, and heart and lung diseases. Long-term exposure to certain types of air contaminants may even increase the risk of cancer.

The best way to protect yourself from air contaminants is to reduce your exposure by limiting your time outdoors in areas with high levels of air pollutants, and to stay indoors during periods of peak air pollution. Wearing a mask can also help to reduce exposure to air contaminants.

In addition to reducing exposure, it is also important to take steps to reduce the amount of air contaminants released into the atmosphere. Choosing renewable energy sources over fossil fuels and reducing the amount of waste produced helps to reduce air pollution and protect public health.
