Winter brings less daylight and colder temperatures, which can disrupt sleep. Seasonal Affective Disorder (SAD) is more common in winter due to the lack of sunlight, causing sleep disturbances.
HOUSTON (AP) — Winter weather brings various hazards that people have to contend with to keep warm and safe. These dangers can include carbon monoxide poisoning, hypothermia and frozen pipes ...
Ammonia is toxic to aquatic life which leads to increased amounts of fish deaths. [6] Ammonia pollution also leads to eutrophication. Eutrophication is the growth of algae that kills other aquatic life and creates dead zones. Ammonia pollution affects freshwater and salt water ecosystems differently due to physical and chemical differences.
Winter can bring intense cold, snow, sleet, and freezing rain across the United States and its territories. Even Hawaii gets snow on its Big Island, and major cities as far south as Atlanta and ...
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 ...
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.

A major winter storm is expected to deliver heavy snow, ice and rain across much of the U.S. this weekend into Monday, affecting areas from the Plains to the mid-Atlantic East Coast. The system ...
The dominant industrial method for producing ammonia is the Haber process also known as the Haber-Bosch process. [70] Fertilizer production is now the largest source of human-produced fixed nitrogen in the terrestrial ecosystem. Ammonia is a required precursor to fertilizers, explosives, and other products. The Haber process requires high ...
