Tahoe, Reno areas have worst air quality in country due to smoke, raising concerns about a Covid surge. … The Air Quality Index, a measure of how unhealthy the air is, spiked to an astonishing 694 in Tahoe City on Monday, according to AirNow.gov. In Reno on Tuesday, the AQI hit 453.
If the air quality is especially poor, it may take a few days for your body to recover. And if you’re regularly exposed to high levels of unhealthy air, the health consequences can linger for months or even years. One of the most-studied pollutants in summertime air is an invisible gas called ozone.
When AQI values are above 100, air quality is considered to be unhealthy, at first for members of populations at greatest risk of a health effect, then for the entire population as AQI values get higher (greater than 150).
High temperatures, minimal precipitation, and a fast-growing population set the backdrop to Las Vegas’s unhealthy air quality. Transportation, construction, and industrial emissions, meanwhile, are the direct culprits for emitting harmful levels of PM2. 5 and ozone precursor pollutants into Las Vegas’ air.
Wearing a highly effective air pollution mask has been shown to help reduce the risk of exposure to PM2. 5 and other airborne particulates, decreasing the chance of illness and death related to air pollution.
In 2019, California’s 5 cleanest cities for PM2. 5 pollution were, Yucca Valley (3.4 μg/m3), Lee Vining (3.6 μg/m3), Twentynine Palms (3.9 μg/m3), Los Gatos (3.9 μg/m3), and Blythe (3.9 μg/m3) respectively.
High air pollution levels can cause immediate health problems including: Aggravated cardiovascular and respiratory illness. Added stress to heart and lungs, which must work harder to supply the body with oxygen. Damaged cells in the respiratory system.
This is because, as the temperature drops during the nighttime hours, the atmosphere traps car emissions, CO2, and other pollutants in the house and down near the ground – and the effect is much worse if spaces inside the home are poorly ventilated. …
According to the Environmental Protection Agency, levels between 301 and 500 are “Hazardous,” meaning people should avoid all outdoor activity. The World Health Organization has standards that judge a score above 500 to be more than 20 times the level of particulate matter in the air deemed safe.
Some parts of India suffer significantly worse than others, with air pollution reducing life expectancy by 9.4 years in Delhi and 8.6 years in Uttar Pradesh, India’s most polluted state. The WHO standard for annual average particle pollution is exceeded in all of India’s 1.4 billion population.
Utah’s air quality index is 51.2, which puts it in the “moderate” AQI range and makes Utah the state with the worst air quality on average.
Nevada skies are almost always blue, but that doesn’t mean the air is safe. The American Lung Association ranks air here as some of the worst in the nation, according to its 2017 State of the Air report.
|Air pollution level||Air quality index||Main pollutant|
|Good||8 US AQI||PM2.5|
Fine particulate matter (PM2.5) is an air pollutant that is a concern for people’s health when levels in air are high. PM2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated.
This temperature (equivalent to 167 degrees Fahrenheit) is easily achieved in hospitals and field settings allowing for the N95s to be reused once decontaminated. This heat treatment can be applied at least 10 times on an N95 respirator without degrading its fit.

Poor air quality results in potential health hazards and often produces a hazy, unattractive ceiling of smog above the basin. … This is due to the Lake Elsinore Convergence Zone, where coastal winds block air pollutants from the rest of the South Coast Air Basin.
An AQI above 150 is listed as “unhealthy” for the general public. … These groups are advised to reduce prolonged or heavy exertion outdoors when an “Unhealthy Air Quality for Sensitive Groups” alert is in effect.
Fine particulate matter, i.e., particles with aerodynamic diameter ≤2.5 μm (PM2.5), is the main component of wildfire smoke1 that impacts public health2,3,4,5. PM2.5 can be inhaled into the deepest recesses of the lungs6 and may enter the bloodstream impairing vital organs including the lungs7.
Anything under 100 is considered satisfactory. Values above 100 begin to get unhealthy, affecting the most sensitive breathers among us initially, and pretty much everyone as it inches toward 500. You can look up your local AQI anytime at AirNow.gov*.
Those most sensitive to air pollution include: children younger than 14. people older than 65. people with heart and lung conditions, including asthma.
When pollution levels are high and air quality alerts are in place, many people may experience an irritation of their respiratory system. This can result in coughing, sore throat, tightness of the chest, irritation of the airways, and even chest pain.
Air pollution may aggravate nasal suffering with colds and seasonal allergies. (Reuters Health) – People who get rhinitis – an inflamed or congested nose – from colds or allergies may feel much worse if they’re exposed to high levels of air pollution, a recent study suggests.
