Air pollution



Heres a little introduction to this project. There are always two ways to look at
something. There is the good way, which in this case would mean looking at all the
positive effects that human intervention has created, These are very few if there are any
at all! Also, there is the other way. This would be the bad way consisting of basic
criticism of all the negative effects that human intervention has caused. These are quite a
few and therefore we shall talk about them. Fortunately for the Amazonian forest, I am
not going to write about every single thing connected to the negative effects on the
environment, but I will talk about several cases, all connected some how to pollution.
Pollution As we discussed in class, there are five main types of pollution. These would be
the following : 1. Air pollution 2. Water pollution 3. Sound pollution 4. Sight pollution 5.
Land pollution Air Pollution Here is my air pollution chart. POLLUTANT MAJOR
SOURCES COMMENTS Carbon monoxide (CO) Motor-vehicle exhaust; some
industrial processes Health standard: 10 mg/m3 (9 ppm) over 8 hr; 40 mg/m3 over 1 hr
(35 ppm) Sulfur dioxide (SO2) Heat and power generation facilities that use oil or coal
containing sulfur; sulfuric acid plants Health standard: 80 g/m3 (0.03 ppm) over a year;
365 g/m3 over 24 hr (0.14 ppm) Particulate matter Motor-vehicle exhaust; industrial
processes; refuse incineration; heat and power generation; reaction of pollution gases in
the atmosphere Health standard: 50 g/m3 over a year; 150 g/m3 over 24 hr;
composed of carbon, nitrates, sulfates, and many metals including lead, copper, iron, and
zinc Lead (Pb) Motor-vehicle exhaust; lead smelters; battery plants Health standard: 1.5
g/m3 over 3 months Nitrogen dioxide (NO2) Motor-vehicle exhaust; heat and power
generation; nitric acid; explosives; fertilizer plants Health standard: 100 g/m3 (0.05
ppm) over a year; reacts with hydrocarbons and sunlight to form photochemical oxidants
Ozone (O3) Formed in the atmosphere by reaction of nitrogen oxides, hydrocarbons,
and sunlight Health standard: 235 g/m3 (0.12 ppm) over 1 hr This is a very well
detailed chart on the different types of causes of air pollution. The first column shows the
pollutant, the second one shows the major source (or where it comes from what causes
it to escape) and the third one shows the comments who health guide lines.
