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]
Long-term exposure to PM 2.5 (fine particulates) increases the overall risk of non-accidental mortality by 6% per 10 μg/m 3 increase. Exposure to PM 2.5 is also associated with an increased risk of mortality from lung cancer (range: 15–21% per 10 μg/m 3 increase) and total cardiovascular mortality (range: 12–14% per 10 μg/m 3 increase ...
Particulate matter (PM), particularly PM2.5, was found to be harmful to aquatic invertebrates. [41] These aquatic invertebrates include fish, crustaceans, and Mollusca. In a study by Han et al, the effects of PM<2.5 micrometers on life history traits and oxidative stress were observed in Tigriopus japonicus.

The highest AQI in India was recorded in New Delhi on 18th November 2024 with it being 1,081 and the concentration of PM2.5 - particulate matter measuring 2.5 microns or less in diameter that can be carried into lungs, causing deadly diseases and cardiac issues. Expected to soar even higher later or next year.

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]
