The reports provide guidelines intending to give guidelines to reduce the health effects of air pollution. [2] The guidelines stipulate that PM 2.5 should not exceed 5 μg/m 3 annual mean, or 15 μg/m 3 24-hour mean; and that PM 10 should not exceed 15 μg/m 3 annual mean, or 45 μg/m 3 24-hour mean. [2]
A 2014 WHO worldwide survey on maternal and perinatal health found a statistically significant association between low birth weights (LBW) and increased levels of exposure to PM 2.5. Women in regions with greater than average PM 2.5 levels had statistically significant higher odds of pregnancy resulting in a low-birth weight infant even when ...
The WHO standard for ozone concentration is 60 μg/m 3 for long-term exposure and 100 μg/m 3 as the maximum average over an 8-hour period. [29] The EPA standard for ozone concentration is 0.07 ppm average over an 8-hour period. [70]

The World Health Organization (WHO) provides guidelines to limit exposure: [165] PM 10: Annual mean not to exceed 15 μg/m³; 24-hour mean not to exceed 45 μg/m³. [165] PM 2.5: Annual mean not to exceed 5 μg/m³; 24-hour mean not to exceed 15 μg/m³. [165] Exposure above these levels increases the risk of adverse health effects. [165]
