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.
She showed that annual increases of 5 μgm −3 PM2.5 particulates in air was comparable to two years of ageing. [11] These investigations allowed her to identify that i populations who live in areas where PM2.5 levels are above the maximum levels recommended by the World Health Organization , COPD is four times higher than in people who ...
Not to be exceeded more than once per year on average over 3 years 40 CFR 50.6: Fine particulate matter (PM 2.5) Primary 9.0 μg/m 3 (12 μg/m 3 prior to May 6, 2024) [25] annual Annual mean, averaged over 3 years 40 CFR 50.18: Secondary 15 μg/m 3: annual Annual mean, averaged over 3 years 40 CFR 50.7: Primary and Secondary 35 μg/m 3: 24-hour
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]

We found the best technology for adults over 65 at CES this year. From AI aids to ‘aging in place’ smart home solutions, the annual tech show kept older users in mind.
A study concluded that PM 2.5 air pollution induced by the contemporary free trade and consumption by the 19 G20 nations causes two million premature deaths annually, suggesting that the average lifetime consumption of about ~28 people in these countries causes at least one premature death (average age ~67) while developing countries "cannot be ...
During the past twenty years, the United States, like many other countries, has seen a dramatic increase in obesity. In 1991, only four states had obesity prevalence rates as high as 15-19% and not a single state had a rate above 20%. By 2005, only four states reported rates below
