Nitrogen oxides are monitored because they are harmful pollutants that can have negative effects on human health and the environment. They contribute to the formation of smog, acid rain, and ground-level ozone, which can lead to respiratory issues, damage to vegetation, and water pollution. Monitoring these pollutants helps to understand their presence in the atmosphere and inform strategies to reduce their impact.
Whether you should worry or not also depends on your water source. If your water source is supplied by a company that has a water-quality assurance program you should not have to worry. However, if your water source is a private well which is not being monitored, you may need to worry if you have reason (e.g. An abandoned gas station or dry cleaner near by). Pollutants can be dissolved in the water and may be tasteless and clear. Therefore, just because water is clear and tastes fine does not mean that it does not contain pollutants.
YES BECAUSE some pollutants are evaporated with water
No
Dispersing pollutants in larger volumes of water is called dilution.
Precipitation can carry pollutants in water whereby when moisture rises and mixes with gases from industries thereby condensing and falling back as acid rain may carry the pollutants into water.
Industry, Animals, Agriculture, and Runoff from roads
There are many types of pollutants, and they are classified by the parts of the environment they pollute. The most common are water pollutants and air pollutants.
Pollutants. This is in my science homework also :)
The Clean Water Act regulates pollutants such as oil and grease, toxic metals, pesticides, and industrial chemicals. These pollutants can come from various sources such as industrial discharges, agriculture runoff, and municipal sewage. The Act sets limits on the amount of these pollutants that can be discharged into water bodies to protect water quality and aquatic life.
Pollutants
The most gaseous pollutants come from a group called "criteria air pollutants." This group includes substances such as carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, and particulate matter. These pollutants are monitored and regulated due to their significant impact on air quality and human health. They can originate from various sources, including vehicle emissions, industrial processes, and natural events.
