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 World Health Organization's recommended limit is 5 micrograms per cubic meter, although there are also various national guideline values, which are often much higher. Air pollution is among the biggest health problems of modern industrial society and is responsible for more than 10 percent of all deaths worldwide (nearly 4.5 million ...
The Convention has been extended by eight protocols that identify specific measures to be taken by Parties to cut their emissions of air pollutants: Protocol on Long-Term Financing of the Cooperative Programme for Monitoring and Evaluation of the Long-range Transmission of Air Pollutants in Europe (EMEP) (1984)
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] For ozone (O 3 ), the guidelines suggest values no higher than 100 μg/m 3 for an 8-hour mean and 60 μg/m 3 peak season mean. [ 2 ]
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.
The measurement is based on the observed relationship of nitrogen dioxide (NO 2), ground-level ozone (O 3) and particulates (PM 2.5) with mortality, from an analysis of several Canadian cities. Significantly, all three of these pollutants can pose health risks, even at low levels of exposure, especially among those with pre-existing health ...
A Donald Trump presidential election victory would have huge implications for U.S. trade policy, climate change, the war in Ukraine, electric vehicles, Americans' taxes and illegal immigration.
Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges .
