Pollutants Hazards Pg 1

There are many different types of pollution that affect our environment and our health each and every day while creating atmospheric issues.

Air Pollutants

Lets start with “Air Pollution” which is created by both human and natural resources including but not limited to CO, SO2, most hydrocarbons, most particulates, CO2, NO, NO2, HNO2, HNO3, H2O2, SO3, H2SO4. Air pollution is a big atmospheric issue that continues to become a greater concern, especially when it comes to the health of living things including humans, animals and plants on our earth.

Carbon dioxide (CO2) can derive from vehicles, factories, furnaces, and etc. Carbon monoxide is poisonous

Ocean waters may suffer from “byecatch”, which is when dolphins, turtles, and other sea or ocean creatures are unintentionally killed by fisherman. Then there is what they call “habitat destruction”, which occurs when trawl catching nets that are dragged along the Ocean floor to catch fish destroy the habitats taking everything with it or pulling it from the Ocean floor and to drop it in another location when it is released from the net. The pollutants that are released into the ocean water ultimately effects our fish and the quality of our produce that we feed off of as well as slowing the rate in which sea and/or ocean animals may …show more content…
(In brief; Heart aches for clean air. Harvard Health Letter) “The Environmental Protection Agency has a Web site, dubbed Air Now (www.epa.gov/airnow), that lists particulate and ozone levels throughout the country.” (In brief; Heart aches for clean air. Harvard Health Letter) “High temperatures in the days ahead increase ground-level ozone, but the seasonality of particulate pollution depends on where you live.” (In brief; Heart aches for clean air. Harvard Health Letter) “East of the Mississippi, levels are highest starting about now through September because sulfates are more readily formed from sulfur dioxide emissions from power plants in warm temperatures.” (In brief; Heart aches for clean air. Harvard Health Letter) “In the western half of the country, levels are higher from October to December because much of the particulate pollution there is in the form of nitrates, which form as temperatures cool off.” (In brief; Heart aches for clean air.

    Since the industry revolution, environmental pollution has gradually become a global problem. It has looks set to hog the limelight in the century. Almost all the countries suffer from such problems and are struggling to keep their heads over the water. Air pollution is something in the air that causes harm to humans or the environment. There are many different forms of air pollutants and these are broken down further into primary and secondary pollutants. A primary pollutant is something that stems directly from a source such as volcanic ash or vehicle emissions. A secondary pollutant forms when two pollutants react in the atmosphere such as acid rain.…

    Gagandeep Rai Period 3/4 Criteria air pollutants assignment Multiple Choice 1. A pungent reddish­brown gas often associated with photochemical smog. (C) NO2 2. A corrosive gas from burning coal often associated with industrial smog. (d) SO2 3. A dangerous indoor air pollutant. (A) CO 4. Emitted from diesel and burning fuel. (E) PM10 5. All of the following are examples of primary air pollutants except. (c) tropospheric ozone 6. The greatest emission of sulfur dioxide comes from (C) Industrial processes 7. The least amount of nitrogen oxide emissions comes from (A) on­ road vehicles 8. The accumulation of tropospheric ozone at night depends mainly upon the atmospheric concentrations of (B) volatile organics 1. What are they? The six criteria air pollutants are sulfur dioxide, nitrogen oxides, carbon oxides,lead,particulate matter and tropospheric ozone. These six pollutants significantly threaten human health, ecosystems and/or structures. 2. How is each produced? Sulfur dioxide is mostly produced from the burning of fossil fuels like coal and oil. It can also be released during volcanic eruptions. Nitrogen oxides are produced from vehicles as well as stationary fossil fuel combustion. Some is also released through lightning and forest fires.Carbon monoxide is formed by incomplete combustion of most matter. Vehicle exhaust and many other combustion process produce Carbon monoxide. It is also a indoor pollutant when exhaust systems on natural gas heaters misfunction. Carbon dioxide is produced from complete combustion of most matter such as biomass and fossil fuels. Particulate matter is released when fossil fuels and bio fuel is burned. Also it is released with activities that involve movement of dust or sand. Lead is released from old paint, gasoline additive and combustion of fossil fuels. Tropospheric ozone is a secondary pollutant and is made by water,sunlight,oxygen,nitrogen oxides and VOCs.…

    Air pollution is the initiation of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. Air pollution occurs when the air contains gases, fumes, dust, or other harmful agents. According to Morgan (2003), air pollution was not a problem until the 19th century and Industrial Revolution because pollution was readily diluted in the atmosphere (Morgan, Environmental Health, 2003, p. 247). Air pollution occurs in many forms but can generally be thought of as gaseous and particulate contaminants that are present in the earth 's atmosphere (Air Pollution - Its Nature, Sources, and Effects, 2013). Natural sources of air pollution include forest fires, dust storms, and volcanic eruptions (Morgan, Environmental Health, 2003, p. 249).…

    Air pollution affects everything from agriculture and ecosystems to human health, on a global scale. The five major air pollutants are ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide (Donnatelle, 2010). A majority of these pollutants are the result of human action. One example being coal power plants. These plants release greenhouse gas emissions and particle air pollution. The burning of the coal creates pollutant byproducts. Other forms of industrial pollution, exhaust fumes, burning wood, and several forms of indoor air pollutants result in air contamination. The combination of various air contaminates can be extremely toxic. The pollutants irritate the lungs and may even cause respiratory diseases and cancer in humans (Donnatelle, 2010).…

    Dr. Laurent Hodges explains some of these issues in her book Environmental Pollution Second Edition. The following summary is from Dr Hodges ' research on the causes of air pollutions. Air pollutions are caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These arise from the burning of coal and from industrial processes. Atmospheric particles can scatter and absorb sunlight which reduces visibility. The second type is sulfur oxides which come from the burning of coal and industrial processes. Damage to materials, to vegetation, and to the human respiratory system is caused by the acid nature of oxides. Small quantities of sulfur oxides can increase illness and mortality. The third type of pollutant is carbon monoxide. Carbon monoxide is a colorless, odorless, tasteless gas against which humans have no protection. Carbon monoxide comes from the exhaust of gasoline-powered vehicles and secondarily from industrial processes. Hemoglobin, which is in the blood, combines with carbon monoxide and carries less oxygen to body tissues causing health and heart effects. Some health problems come from the exhaust fumes leaking…

    Air lets our living planet breathe—it's the mixture of gases that fills the atmosphere, giving life to the plants and animals that make Earth such a vibrant place. Broadly speaking, air is almost entirely made up of two gases (78 percent nitrogen and 21 percent oxygen), with a few other gases (such as carbon dioxide and argon) present in absolutely minute quantities. We can breathe ordinary air all day long with no ill effects, so let's use that simple fact to define air pollution, something like this:…
