Air Quality Alert
CAZ569-100700-
Palo Verde Valley-
Including the cities of Martinez Lake, Blythe, Palo Verde,
and Ripley
229 PM PDT Wed Jul 3 2024
...AIR QUALITY ALERT FOR ELEVATED OZONE AIR POLLUTION...
The Mojave Desert AQMD has issued an air quality alert in the High
Desert of San Bernardino County and Palo Verde Valley in Riverside
County due to high levels of ozone (smog). The air quality alert is
in effect Wednesday, July 3 through Tuesday, July 9, 2024.
Elevated levels of ozone the predominant summertime pollutant
are likely to result in poor air quality in the afternoon and early-
evening hours. Ozone air pollution can cause respiratory health
problems, including trouble breathing, asthma attacks, and lung
damage. Children, older adults, and people with asthma or COPD may be
more sensitive to the health effects of ozone.
Air quality can change depending on time of day and weather
conditions. Increased emissions of chemicals and faster ozone
formation rates due to heat, along with low winds and stagnant
weather can cause unusually high and persistent levels of ozone
pollution.
To help minimize ozone air pollution levels:
* Limit the use of gasoline powered lawn and garden equipment until
evening hours
* Conserve electricity and set your air conditioner at a higher
temperature
* Try to delay trips to the gas station and the use of household
chemicals until the evening
Check air quality levels and take appropriate action as needed. When
air quality index (AQI) levels are Unhealthy for Sensitive Groups
(orange), people with heart or lung disease, pregnant women,
children, and older adults should limit prolonged or heavy outdoor
exertion. When air quality reaches Unhealthy (red) AQI levels,
everyone may experience adverse health effects and sensitive groups
should avoid prolonged time outdoors. At Very Unhealthy (purple) AQI
levels, sensitive groups should avoid all outdoor physical activity
and everyone else should avoid prolonged or heavy outdoor exertion.
In the High Desert of San Bernardino County, to view current and
forecasted air quality levels, visit the Mojave Desert Air Quality
Management District website at mdaqmd.ca.gov.Additional details for
this air quality advisory are available at
www.mdaqmd.ca.gov/advisories.

...AIR QUALITY ALERT FOR AIR POLLUTION DUE TO ELEVATED OZONE AND
ELEVATED LEVELS OF FINE PARTICLE MATTER...
The South Coast AQMD has issued an air quality alert in inland parts
of the South Coast Air Basin and the Coachella Valley due to high
levels of ozone (smog). The air quality alert is in effect 11 AM
Wednesday through 7 PM Saturday.
Elevated levels of ozone the predominant summertime pollutant
are likely to result in poor air quality in the afternoon and early-
evening hours. Ozone air pollution can cause respiratory health
problems, including trouble breathing, asthma attacks, and lung
damage. Children, older adults, and people with asthma or COPD may
be more sensitive to the health effects of ozone.
Exposure to particle pollution can cause serious health problems,
aggravate heart and lung disease, cause asthma attacks and acute
bronchitis, and increase risk of respiratory infections. People with
respiratory or heart disease, older adults, and children are
particularly susceptible.
Air quality can change depending on time of day and weather
conditions. Increased emissions of chemicals and faster ozone
formation rates due to heat, along with low winds and stagnant
weather can cause unusually high and persistent levels of ozone
pollution.
To help minimize ozone air pollution levels:
* Limit the use of gasoline powered lawn and garden equipment until
evening hours
* Conserve electricity and set your air conditioner at a higher
temperature
* Try to delay trips to the gas station and the use of household
chemicals until the evening
To help keep indoor air clean during periods of poor air quality,
close all windows and doors and run your air conditioner and/or an air
purifier. If possible, do not use whole house fans or swamp coolers
that bring in outside air. Avoid burning wood in your fireplace or
firepit and minimize sources of indoor air pollution such as candles,
incense, pan-frying, and grilling. Limit the use of gasoline powered
lawn and garden equipment.
Check air quality levels and take appropriate action as needed.
When air quality index (AQI) levels are Unhealthy for Sensitive
Groups (orange), people with heart or lung disease, pregnant women,
children, and older adults should limit prolonged or heavy outdoor
exertion. When air quality reaches Unhealthy (red) AQI levels,
everyone may experience adverse health effects and sensitive groups
should avoid prolonged time outdoors. At Very Unhealthy (purple) AQI
levels, sensitive groups should avoid all outdoor physical activity
and everyone else should avoid prolonged or heavy outdoor exertion.
