An example of this is the hollow-fiber gas-permeable membranes in wastewater treatment. Companies that polluted less than their cap could trade or sell their remaining pollution allowance to other companies. Other air pollutants Other major air pollutants that are classified as carcinogen and mutagen compounds and are thought to be responsible for incidence and progression of cancer in human include VOCs such as benzene, toluene, ethylbenzene, and xylene, PAHs such as acenaphthene, acenaphthylene, anthracene, and benzopyrene, and other organic pollutants such as dioxins, which are unwanted chemical pollutants that almost totally produced by industrial processes and human activity.
Some of the water pollutants according to the authors include industrial chemicals e. Due to its solubility in water, SO2 is responsible for acid rain formation and acidification of soils.
A biological, chemical, and physical alteration of the air occurs when smoke, dust, and any harmful gases enter into the atmosphere and make it difficult for all living beings to survive as the air becomes contaminated.
These results illustrate the complexity of the effects of EDCs on the HP axis and the difficulty of extrapolating between, or even within, species.
The effects of air pollution are alarming.
