Air quality in Mannehundi is currently good.

NO₂ levels are currently Good.

Nitrogen oxides, particularly nitrogen dioxide (NO₂), are expelled from high temperature combustion. NO₂ is a reddish-brown toxic gas has a characteristic sharp, biting odor, and can be seen as a brown-ish plume downwind of cities

SO₂ levels are currently Good.

Sulfur oxides, particulary Sulfure Dioxide (SO₂) is produced by in various industrial processes, especially when involving fuel combustion, and also by volcanoes. Coal and petroleum often contain sulfur compounds, and their combustion generates sulfur dioxide. Further oxidation of SO₂ can produce acid rain.

O₃ levels are currently Good.

Ground level ozone is formed in chemical reactions by NOx and VOCs in the presence of sunlight. High concentrations of O₃ can be a constituent of smog.

NO levels are currently Unknown.

Nitrogen oxides are expelled from high temperature combustion. Nitrogen oxide (NO) is a colorless and toxic gas. It plays a role in depleting earth's ozone layer and is a precursor to the more dangerous NO₂.

CO levels are currently Good.

Carbon monoxide is a colorless, odorless, toxic gas. It is a product of combustion of fuel such as natural gas, coal or wood. Vehicular exhaust contributes to the majority of carbon monoxide let into our atmosphere. It creates a smog type formation in the air that has been linked to many lung diseases and disruptions to the natural environment and animals.

C₆H₆ levels are currently Unknown.

Benzene is one of many volatile organic compounds (VOCs) and a natural constituent of crude oil.
It is a known carcinogen, a substance that promotes the formation of cancer, and is harmful even in tiny amounts. Long term exposure to excessive levels of benzene in the air can cause leukemia.
Benzene has a characteristic sweet smell and is responsible for the aroma around gasoline stations. The most common sources of exposure to benzene are tobacco smoke, gasoline stations and vehicular exhausts.
