Air Quality Information for the North Coast


General Air Quality Information in the North Coast
The air in Humboldt, Del Norte and Trinity County is considered to be in "in attainment" of state and federal ambient air quality standards except for the State's 24-hour PM10 standard for Humboldt County only. The two pollutants of greatest concern in the region are ozone and particulate matter. The county's sunny climate, pollution-trapping mountains and valleys, along with the growing population, all contribute to the problem.
Ozone is an invisible pollutant formed by chemical reactions involving nitrogen oxides, reactive hydrocarbons and sunlight. It is a powerful respiratory irritant that can cause coughing, shortness of breath, headaches, fatigue and lung damage, especially among children, the elderly, the ill and people who exercise outdoors.
Particulate Matter is fine mineral, metal, soot, smoke and dust particles suspended in the air. Primary sources of particulate matter in the Eureka area are on-road and off-road vehicles (engine exhaust and dust from paved and unpaved roads), open burning of vegetation (both residential and commercial), residential wood stoves, and stationary industrial sources (factories). For health reasons, we are most concerned with particulate matter less than 2.5 microns in diameter (PM2.5). Particles of this size and smaller can permanently lodge in the deepest, most sensitive areas of the lungs, and cause respiratory and other health problems. The California Air Resources Board recently concluded that PM2.5 is far more hazardous than previously estimated.
