=== Air pollution ===
{{Unreferenced section|date=December 2022}}
[[Air pollution]] is a growing problem that affects all of the citizens in the Central Valley. Some reasons of poor air pollution in the Central Valley are due to agriculture and its geographical features, increasing the stagnation of automobile and other particulate pollution.

Since the Central Valley consists mostly of farming land in a wide, flat valley, the emissions from the soil that is used for growing produce are released into the air. The soil exudes [[nitrous oxide]], an odorless and colorless gas that can be harmful when exposed to it for a long period of time, and incorporates itself into the ozone layer located at ground level.<ref>{{Cite web |last=Comm |first=Bren |date=2019-03-04 |title=The surprising driver of air pollution in the California Central Valley |url=https://www.brencomm.com/post/the-surprising-driver-of-air-pollution-in-the-california-central-valley |access-date=2022-12-20 |website=Bren Communication |language=en}}</ref> Production of nitrous oxide in California has shown that the addition of soil and [[fertilizer|fertilization]] can emit about 161,100 metric tons per year. Long term effects that nitrous oxide can have on a human being is loss of blood pressure, fainting, anemia, or lung cancer.

The physical geographical attributes can also contribute to the air pollution quality. The Central Valley is surrounded by mountain ranges which can capture the pollution coming from the agricultural farming, preventing it from dispersing from the other areas in California.<ref>{{Cite news |date=2011-09-28 |title=Why Does California's Central Valley Have Such Bad Air Pollution? |language=en |work=Bloomberg.com |url=https://www.bloomberg.com/news/articles/2011-09-28/why-does-california-s-central-valley-have-such-bad-air-pollution |access-date=2022-12-20}}</ref>
