Poisonous humes in to atmosphere causing
Answers
Answer:
Sulphur oxides (SOx) – Mainly Sulphur dioxide (SO2). It is one of the causes for concern over the environmental impact of the use of fuels as power sources.
Nitrogen oxides (NOx) - NO2 is one of the most prominent air pollutants. Nitrogen (N) compounds, emitted as NOX and NH3, are now the principal acidifying components in our air and cause eutrophication of ecosystems.
Particulate matter - Particulates, alternatively referred to as particulate matter (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols.
Ozone (O3) - Ozone is not directly emitted into the atmosphere but formed from a chain of photochemical reactions following emissions of precursor gases: nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOC).
Carbon monoxide (CO) - It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of carbon monoxide.
Carbon dioxide (CO2) - emitted from sources such as combustion, cement production, and respiration.
Heavy metals, such as arsenic (As), cadmium (Cd), lead (Pb) and nickel (Ni)
Benzene and benzo(a)pyrene
Ammonia (NH3) - emitted from agricultural processes.
Explanation:
Ozone-depleting substances
The stratosphere, a high layer of the atmosphere contains a high concentration of ozone. Ozone layer depletion allows a greater amount of ultraviolet (UV) radiation to reach the surface of the earth. An increase of UV radiation levels implies a significant harm to human health (skin cancer, cataracts, damage to the immune system) and to ecosystems, wild life and agriculture.
Some ozone-depleting substances are assigned with risk phrase R59 (according to DSD) and EU hazard statement system EUH059 (according to CLP): Hazardous to the ozone layer.
Greenhouse gases
Air pollution may also impact the Earth"s climate. Some air pollutants interfere with the Earth"s energy balance and are therefore known as "climate forcers".
These can either be gases (e.g. ozone) or airborne particulate matter (aerosols). Some climate forcers reflect solar radiation (e.g. sulphate aerosols) leading to net cooling, while others (e.g. black carbon aerosols) absorb solar radiation, thereby warming the atmosphere. In addition, aerosols influence the formation, microphysics and optical properties of clouds, resulting in indirect climatological effects.
Deposition of certain aerosols (e.g. black carbon) may also change the Earth"s surface reflectivity (albedo), especially on ice- and snow-covered surfaces, thereby accelerating melting.
The “greenhouse effect” is an increase of the average global temperature due to the accumulation of polluting gases in higher atmospheric levels that causes regional and global climate change.
The most visible greenhouse effects include:
increased frequency of extreme weather events (floods, draughts, retreating glaciers)
increase of sea level
extreme winter/ summer temperature differences
reduction of agricultural production in certain regions
alteration of natural systems
