The primary toxicity of pulmonary agents is to the airway and follows inhalation of smoke, particles, vapors, or gases

Explanation:

Toxic substances which are in the form of gases, dust, vapors, fumes, fibers, etc. are able to penetrate organisms by inhalation through both the upper airways and the alveoli.

The respiratory system consists of the upper airways and the lungs.

The pathway of toxic substances through the respiratory system will depend on the body's reaction to these agents. Toxic substances are often grouped into particles and, depending on their size, do not even reach all the respiratory compartments.

This would be an example of nonpoint source pollution.

Explanation:

The source of point source pollution is typically factories and powerplants, leading to more air and water transferred pollutants and becoming easier to track. Nonpoint source pollution is the opposite of point-source pollution, with pollutants being released in a wide area. Since the rainwater would be washing the oils and particles into the water, it would be considered runoff. Runoff is one of the leading causes of point source pollution. I hope this helps. ^_^
