Some of the largest sources of emissions in Ventura County come from motor vehicles, industry, and agriculture. Currently Ventura County is still working on meeting state and federal standards for harmful particles, called particulate matter, from industry and transportation. The top three air emission concerns in Ventura County are: Ozone gas occurs both in the Earth’s upper atmosphere and at ground-level. At the ground-level, ozone is a harmful air pollutant and is the main ingredient in smog. Ozone is created when NOx (oxides of nitrogen) and VOC (volatile organic compounds) react – like when pollutants emitted by cars, power and chemical plants, refineries, and other fossil fuel combustion chemically react in the presence of sunlight. Ozone is most likely to reach unhealthy levels on hot sunny days in urban environments, but can still reach high levels during colder months and can be transported by winds to rural areas. Particulate matter is a combination of fine solids such as dirt, soil dust, pollens, molds, ashes and soot, and aerosols that are formed in the atmosphere from combustion of fossil fuels. Individually, these particles and droplets are not visible to the naked eye. Collectively, however, they reduce visibility and can appear as cloud or fog-like haze. While not considered an inhalation hazard, greenhouse gases (GHG) emissions are a concern to the health of Ventura County residents – especially with our high vulnerability to fires, drought, heat stress and floods. The largest source of GHG emissions in the United States is from burning fossil fuels (coal, oil and natural gas) for electricity, building and water heating, and transportation. Because air pollution and GHG are often released from the same sources, cutting GHG emissions to slow climate change also reduces air pollutants, like those listed above. Lungs are the greatest source of exposure to air pollution. According to recent studies, air pollution kills about 50,000 people in the United States each year – from heart disease, asthma, stroke, bronchitis, and other illnesses. That is more people than die in car accidents! The potential health threat from smog is greater in California than it is in any other state. Researches estimate that one in five people are extremely susceptible to severe health damage as a result. Ground-level ozone, the primary ingredient of city smog, can cause numerous health effects including: Pollutant exposure can also reduce resistance to infections – like COVID-19.
