Gaseous ammonia reacts with other pollutants in the air to form fine particles of ammonium salts, which affect human breathing. Ammonia gas can also affect the chemistry of the soil on which it settles and will, for example, degrade the conditions required by the sphagnum moss and heathers of peatland. [1] [2] [3] [4]
Ammonia occurs in nature and has been detected in the interstellar medium. In many countries, it is classified as an extremely hazardous substance. [15] Ammonia is produced biologically in a process called nitrogen fixation, but even more is generated industrially by the Haber process. The process helped revolutionize agriculture by providing ...
How winter weather can sneak up on you — and what to do. The biggest health risks posed by freezing temperatures and windchill are frostbite and hypothermia, and they can happen quickly, says ...
Growing evidence that air pollution—even when experienced at very low levels—hurts human health, led the WHO to revise its guideline (from 10 μg/m 3 to 5 μg/m 3) for what it considers a safe level of exposure of particulate pollution, bringing most of the world—97.3 percent of the global population—into the unsafe zone.
Learn how to get a good night’s sleep during a heat wave from experts from the United States and Europe — including how to sleep cooler.
Ammonia is lethal in certain doses, but proper preparation and emergency protocols can mitigate these risks down to as little as one death per decade, according to the EPA. [1] The unusual smell of ammonia is one reason for that, which allows humans to detect leaks at as low as 5ppm, while its toxic effects begin above 300ppm. [1]
On Wednesday, there were 21 heat-related deaths at Beni Mellal’s main hospital as temperatures spiked to 48.3 degrees (118.9 degrees Fahrenheit) in the region of 575,000 people, most lacking air ...
Climate change increases the frequency and severity of heatwaves and thus heat stress for people. Human responses to heat stress can include heat stroke and overheating (hyperthermia). Extreme heat is also linked to acute kidney injury, low quality sleep, [21] [22] and complications with pregnancy.
