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.
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 ...
Major energy companies understood at least since the 1960s that use of their products causes widespread adverse health effects and death but continued aggressive political lobbying in the United States and elsewhere against clean air regulation and launched major corporate propaganda campaigns to sow doubt regarding the causative link between ...
While food poisoning can happen to anyone, this is one dinner table staple you shouldn't mess with.
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
Inhalation is a major route of exposure that occurs when an individual breathes in polluted air which enters the respiratory tract. Identification of the pollutant uptake by the respiratory system can determine how the resulting exposure contributes to the dose. In this way, the mechanism of pollutant uptake by the respiratory system can be ...
The smaller ammonium PM2.5 can also travel further distances (100–1000 km) when compared to unreacted ammonia (less than 10–100 km) in the atmosphere. [4] Some countries like China have focused on reducing SO 2 and NO X emissions, however increased NH 3 pollution still results in PM2.5 formation and reduces air quality. [ 28 ]
One day of exposure to PM2.5 at a concentration of 880 μg/m 3, such as occurs in Beijing, China, is the equivalent of smoking one or two cigarettes in terms of particulate inhalation by weight. [ 25 ] [ 26 ] The analysis is complicated, however, by the fact that the organic compounds present in various ambient particulates may have a higher ...
