...AIR QUALITY ALERT IN EFFECT UNTIL 8 PM PDT MONDAY...
The South Coast Air Quality Management District has issued an Air
Quality Alert due to elevated fine particulate matter levels due to
wildfire smoke and high ozone levels. This Air Quality Alert is IN
EFFECT UNTIL 8 PM PDT MONDAY
The South Coast AQMD has extended an air quality alert in the South
Coast Air Basin due to high levels of ozone (smog) due to the
ongoing heat wave and updated an air quality alert due to increased
fine particle pollution from wildfire smoke in the region. The air
quality alert is in effect until Monday evening for smog and Sunday
evening for wildfire smoke.
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
If you smell smoke or see ash due to a wildfire, remain indoors with
windows and doors closed or seek alternative shelter, if feasible.
Avoid vigorous physical activity 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. If you must be
outdoors, keep the time brief and wear a tightly-fitted N-95 or P-
100 respirator to help reduce exposure. Limit the use of gasoline
powered lawn and garden equipment.
Exposure to particle pollution can cause serious health problems,
aggravate lung disease, cause asthma attacks and acute bronchitis,
and increase risk of respiratory infections. People with heart or
lung diseases should follow their doctor`s advice for dealing with
episodes of unhealthy air quality. Additionally, people with
respiratory or heart disease, older adults, and children are
particularly susceptible and should avoid prolonged exposure,
strenuous activities or heavy exertion as conditions dictate.
Levels of particle pollution can vary hour by hour and by location
depending on fire behavior and local weather conditions.
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.

Coast Air Quality Management District website at aqmd.gov or

...AIR QUALITY ALERT FOR ELEVATED OZONE AIR POLLUTION AND ELEVATED
FINE PARTICLE POLLUTION LEVELS DUE TO WILDFIRE SMOKE...
The South Coast AQMD has extended the air quality alert in the South
Coast Air Basin due to high levels of ozone (smog) and increased
fine particle pollution from wildfire smoke in the region. The air
quality alert is in effect until Monday evening for smog and Sunday
evening for wildfire smoke.
High ozone levels are expected to impact most of the South Coast Air
Basin. Smoke is expected to impact the Inland Empire and the San
Bernardino Mountains.
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.
