Influences of wildfires on Los Angeles air quality.

The city of Los Angeles, which is famed for bright blue skies and an explosive culture, can be found buried under a haunting orange haze each year. Now that wildfires are becoming more common and more intensive, the concern over their impacts on air quality makes the issue pertinent. This blog outlines how air quality is compromised in Los Angeles with regard to wildfires and significant implications for public health, the environment, and the economy.

 What does a wildfire even smell like?

Wildfire smoke is quite a toxic cocktail whose pollutants greatly hamper air quality as such. The main component is particulate matter (PM2.5); tiny particles 2.5 microns or smaller can penetrate deeply into the lungs as well as the bloodstream. Other harmful pollutants released include:  

- Carbon monoxide (CO): restricts oxygen transport in the body.  

- Voilatile organic compounds (VOCs): contribute to the formation of ground-level ozone.  

- Toxic Chemicles: substances like benzene and formaldehyde, carcinogenic. Tap to watch! 

Wildfire smoke tends to produce, in comparison to urban pollution resulting from traffic and industry, even higher concentrations of PM2.5, which means it is even more dangerous. 

A Historical Overview of Wildfires and Air Quality in Los Angeles

Los Angeles has had many destructive wildfires that have had significant effects on its air quality.  

- The Woolsey Fire (2018): It engulfed almost 100,000 acres and put forth major pollutants into the air.  

- The Saddleridge Fire (2019): This event wasn't a major fire but, in fact, was quite an adding source to the already stressed air quality of the city.  

The wildfire seasons in Los Angeles have become longer and more intense year over year, trending with climate change and above-normal drought conditions. According to the California Air Resources Board (CARB), wildfire smoke has significantly increased in the percentage of the annual air pollution burden for California. Today's update!

 The Health Effects of Wildfire-Generated Air Pollution

 Immediate Health Consequences

Wildfire smoke is known to pose direct, immediate risks such as:  

- Smoldering or burning sensation in the eyes, nose, and throat.  

- Breathing difficulties, especially wheezing, in individuals with asthma or other respiratory illnesses.  

- Increased risk of heart attack or stroke.  Health effect details! 

 Long-Term Health Dangers

Long-term exposure to PM2.5 may lead to:  

- Chronic respiratory diseases, such as bronchitis and asthma.  

- Cardiovascular-related illnesses, as well as a higher incidence of heart attacks.  

- Possible carcinogenicity due to exposure to dangerous chemicals.  

 Vulnerable Populations: Children, the elderly, and those with pre-existing health conditions are at higher risk, which makes wildfire smoke unhealthy for a broader section of the community. 

 Public Health Data

As reported by the American Lung Association, there was a 20% rise in visits to the emergency room for respiratory conditions during large wildfire events across California. Health tips here!

Consequences on Environment and Economy  

 Environmental Effects  

The harmful effects of wildfires range from polluting the air to damaging entire ecosystems.  

- Damage to Plant Life: Smoke prevents sunlight from getting to plants which limits their photosynthesis process.

- Harm to Wildlife: Animals tend to suffer from respiratory problems and habitat loss. 

- Greenhouse Gases: Carbon dioxide and methane are some of the gases released by wildfires, contributing to the worsening of climate change.  

 Economic Costs  

The economic cost-inflation of air pollution via wildfires is very high:  

- Healthcare Costs: There is a huge spike in treatment needed for respiratory and cardiovascular conditions.  

- Industry Losses: Poor air quality could lead to a lot of time lost when businesses have to shut, along with productivity drops, and losses in tourism.  

- Property Damages: Smoke may infiltrate houses and businesses, leading to costly decontamination.  Economical effects!

 Monitoring and Mitigating Air Quality During Wildfires

 Monitoring Air Quality in Los Angeles  

Monitoring tools use the Air Quality Index (AQI) to measure pollution levels, with anything above 150 considered unhealthy. Organizations like South Coast Air Quality Management District (AQMD) and AirVisual also air free updates as they happen.  

 Public Safety Precautions  

Here are ways residents can protect themselves:  

- Utilize N95 Masks: These are masks which filter PM2.5 particles in the air.  

- Stay Indoors: Keep windows and doors closed to lower exposure.  

- Invest in Air Purifiers: Devices that would improve indoor air quality significantly while being HEPA.  Safe zone for public! 

The Part of Climate Change in Intensifying Wild Fires and Air Pollution

 Climate Change as the Ignition Source

Increased global temperatures and extended droughts have formed a perfect storm for wildfires.  

- Higher temperatures dry out vegetation to create more fuel for fires.  

- Extreme weather events, like heat waves, further exacerbate the conditions.

 The Feedback Loop

Wildfires help cause further climate change by liberating huge quantities of  carbon dioxide into the atmosphere, which worsens the effects of global warming. Hence, hotter climates would be associated with wildfires getting more frequent and intense.

 Tips on How to Be Prepared for Wildfire Season

1.  Follow AQI Levels: With apps such as AirNow or PurpleAir.  

2. Make a Clean Room: Give a room an air purifier and escape bad air.  

3. Evacuation Plans: Have an emergency bag with masks, medications, and documents.  

4. Do Not Go Outdoor Activities: Don't plan strenuous activities outside when the air quality is bad.
