Naturally occurring pollutants include those omitted by volcanoes and forest fires.
Ozone (O3).
Ozone is a naturally occurring gas in the stratosphere, where it plays a vital role in absorbing harmful ultraviolet radiation. However, in the lower atmosphere, ozone is considered a pollutant as it is a key component of smog and can have adverse effects on human health and the environment.
No. A dump doesn't appear without human involvement. Dumps are created by humans, not nature.
No, argon is not considered a pollutant. It is a naturally occurring inert gas that does not react with other substances in the atmosphere to form harmful pollutants. Argon is non-toxic and is used in various applications such as welding and lighting.
Barium is a naturally occurring element that is not essential for human health, so it is considered a pollutant when present in high levels in the environment. Ingesting high amounts of barium can be harmful to health, leading to symptoms such as nausea and vomiting.
Ozone is a naturally occurring gas in the stratosphere that acts as a protective layer against the sun's harmful UV radiation. However, when present in the lower atmosphere as a result of pollution, it can contribute to smog formation and respiratory issues.
appy is the naturally occurring base.
naturally occurring.
Yes it is a naturally occurring mineral.
Ozone (O₃) is a naturally occurring gas in the stratosphere, where it forms the ozone layer that protects the Earth from harmful ultraviolet (UV) radiation. However, at lower altitudes in the troposphere, ozone is considered a pollutant, as it is a harmful component of smog and can have detrimental effects on human health, vegetation, and the environment. Its presence at ground level is primarily a result of human activities, including emissions from vehicles and industrial processes.
Argon itself is not considered a pollutant as it is a naturally occurring non-reactive gas that makes up about 1% of the Earth's atmosphere. However, if it is released in excessive amounts due to human activities, it could displace oxygen and pose a safety hazard in enclosed spaces.
The "Chaparral Biome" is characterized by naturally occurring fires.
