Question

Air Pollution The amount of nitrogen dioxide, a brown gas that impairs breathing, present in the atmosphere on a certain May day in the city of Long Beach is approximated by A(t)= 133/1+0.25(t-4.5)²+26(0≤t≤11) × PSI .

Answer 1

Air pollution involves harmful substances like Nitrogen dioxide (NO₂) and other pollutants produced mainly by fossil fuel combustion. These pollutants contribute to smog, respiratory problems, and environmental issues. Measures to reduce emissions and monitor air quality are essential for public health.

Step-by-step explanation:

Air pollution is a significant problem with various harmful substances being introduced into the earth's atmosphere. Nitrogen dioxide (NO₂) is a reddish-brown toxic gas and a prominent air pollutant produced by internal combustion engines. It contributes to the formation of smog, impairs breathing, and can cause a range of respiratory issues. In addition to NO₂, other pollutants such as carbon monoxide (CO), sulfur dioxide (SO₂), lead (Pb), and particulate matter (PM) also pose serious health risks. The combustion of fossil fuels by vehicles, power plants, and industrial processes is a major contributor to these emissions, leading to detrimental effects on human health, visibility in national parks, and nutrient pollution in coastal waters.

Indoor air pollution can also be of concern, as it sometimes contains higher levels of pollutants than outdoor air. Household appliances like gas stoves and kerosene heaters can increase indoor levels of NO₂ and other pollutants like CO, which can be fatal when inhaled in high concentrations. As such, monitoring air quality and taking measures to reduce emissions of these pollutants are crucial for protecting public health and the environment.
