Asthma and PM10

Asthma and PM10

PM10 (the mass of particles present in the air having a 50% cutoff for particles with an aerodynamic diameter of 10 microm) is the standard measure of particulate air pollution used worldwide. Epidemiological studies suggest that asthma symptoms can be worsened by increases in the levels of PM10. Epidemiological evidence at present indicates that PM10 increases do not raise the chances of initi...

Linking Endotoxins, African Dust PM10 and Asthma in an Urban and Rural Environment of Puerto Rico

African Dust Events (ADE) are a seasonal phenomenon that has been suggested to exacerbate respiratory and proinflammatory diseases in Puerto Rico (PR). Increases in PM10 concentration and the effects of biological endotoxins (ENX) are critical factors to consider during these storms. ENX promote proinflammatory responses in lungs of susceptible individuals through activation of the Toll-like re...

Protecting Our Children: Assessing the Link between PM10 Pollution and Childhood Asthma in Maricopa County

Short-Term Effects of PM10 and NO2 on Respiratory Health among Children with Asthma or Asthma-like Symptoms: A Systematic Review and Meta-Analysis

OBJECTIVE Our goal was to quantify the short-term effects of particulate matter with aerodynamic diameter < or = 10 microm (PM10) and nitrogen dioxide (NO2) on respiratory health of asthmatic children from published panel studies, and to investigate the influence of study and population characteristics as effect modifiers. DATA EXTRACTION After a systematic literature review, we extracted qua...

Characteristics: Ambient Pm10 Samplers

The National Ambient Air Quality Standards (NAAQS) for PM in terms of PM10 are ambient air concentration limits set by the EPA that should not be exceeded. Further, some state air pollution regulatory agencies (SAPRAs) utilize the NAAQS to regulate criteria pollutants emitted by industries by applying the NAAQS as property-line concentration limits. Prior to and since the inclusion of the PM10 ...
