Final answer:
Poor air quality in California, especially during fire seasons, leads to respiratory symptoms and can cause long-term health conditions like heart disease, lung cancer, and COPD. High-risk groups include those with existing health conditions, the elderly, and children. Protecting oneself involves staying informed about air quality levels and using indoor air purification methods.
Step-by-step explanation:
Respiratory Symptoms and Long-term Conditions from Poor Air Quality Exposure
Poor air quality, particularly from fire seasons in California, can lead to various respiratory symptoms such as wheezing, coughing, chest tightness, and shortness of breath. These symptoms can affect many individuals, especially those with pre-existing conditions such as asthma or cardiovascular diseases. Long-term exposure to low air quality can result in chronic health conditions, including the development of heart disease, lung cancer, chronic obstructive pulmonary disease (COPD), and aggravation of existing lung diseases like asthma and bronchitis.
It is important to note that individuals with respiratory and cardiovascular conditions, along with other sensitive populations including the elderly and children, are at higher risk of experiencing these adverse health effects. Methods to protect oneself from poor air quality include monitoring local air quality reports, staying indoors when air quality is poor, and using air purifiers to reduce indoor air pollution.
With regards to the primary source of cancer from air pollution, it is believed to be particles such as PM2.5, which are a byproduct of combustion from sources like vehicle emissions and industrial activities. These tiny particles can penetrate deep into lung tissue and even enter the bloodstream, causing various health problems. Smog, which often comprises ozone and particulate matter, can exacerbate respiratory issues and is formed by a reaction between pollutants and sunlight.
