[FONT="] I have done what I can with it. It was difficult having to cut and paste it from your Word document so the formatting has gone a little strange. I have no technical knowledge of the subject so have left anything like that alone.[/FONT]
[FONT="]In future, if you could post such things in small sections, it would be easier for us to check. Thanks.[/FONT]
[FONT="]Here is what I have amended:
[/FONT]
[FONT="]NONPOINT SOURCE POLLUTION – IT’S ALL AROUND US. REPORT.[/FONT]
[FONT="]A. Visit three agricultural or urban / construction sites and answer each of the following questions for each site in a short report.[/FONT]
[FONT="]1. What diffuse pollutants did you observe? List as many as you can. Are there possibly other diffuse pollutants that you cannot see? If so, list them.[/FONT]
[FONT="]2. What is the probable cause/source of each pollutant you observed or suspect is present?[/FONT]
[FONT="]I decided to analyze agricultural and urban sites
in Russia, [/FONT][STRIKE]as[/STRIKE][FONT="] my
home country. [/FONT]
[STRIKE]This is[/STRIKE]
First, I visited a[FONT="] wheat field. I think here we can observe diffuse pollutants [/FONT][STRIKE]like[/STRIKE]
such as[FONT="]: [/FONT]
[FONT="]- [/FONT][FONT="]Insecticides (DDT
may be used,
the soil
has already [/FONT][STRIKE]has[/STRIKE][FONT="] absorb
ed [/FONT][STRIKE]a lots of[/STRIKE]
many[FONT="] toxic chemicals such as Alumin
ium, arsenic, chlorine etc.). Birds, rodents and other wildlife could be poisoned. To reduce this pollution, [/FONT][STRIKE]they could use[/STRIKE][FONT="] biological insecticides
could be used. (Wikipedia,
Insecticide - Wikipedia, the free encyclopedia) [/FONT]
[FONT="]- [/FONT][FONT="]Fertilizers (nitrates accumulation in groundwater, soil acidification, heavy metal (cadmium, uranium) accumulation). To avoid or minimize this effect we [/FONT][STRIKE]may[/STRIKE]
could[FONT="] use eco-friendly fertilizers.[/FONT]
[FONT="]- [/FONT][FONT="]herbicides[/FONT]
[FONT="]- [/FONT][FONT="]oil, grease drops and tire (tyre in BrE) [/FONT][STRIKE]crumb[/STRIKE][FONT="]dust from grain harvester combines (combine harvesters) and tractors.

[/FONT]
[FONT="]This is one of the bus
iest streets [/FONT][STRIKE]of[/STRIKE]
in[FONT="] Kazan. [/FONT][STRIKE]What pollutants I can observe: [/STRIKE]
I observed the following pollutants:
[FONT="]- [/FONT][FONT="]Automobile oil, grease, gas, tire [/FONT][STRIKE]crumbs[/STRIKE]
dust[FONT="] on the asphalt. [/FONT]
[FONT="]- [/FONT][FONT="]Toxic car emission
s: Carbon dioxide, monoxide, lead (plumbum), nitrogen oxides, unbur
ned fuel, sulfur dioxide, benzene, toluene, xylene, 1,3-butadiene, acetaldehyde, and formaldehyde.[/FONT]
[FONT="]- [/FONT][FONT="]
Lawn fertilizers [/FONT][STRIKE]for lawn[/STRIKE][FONT="]. [/FONT]
[FONT="]- [/FONT][FONT="]After rain
, all this matter
is washed [/FONT][STRIKE]off[/STRIKE]
away[FONT="] and settles in the creek. [/FONT]
[FONT="]- [/FONT][FONT="]Air conditioner
gas (Air conditioner Freon rises into the sky and destroys
the ozone layer). [/FONT]
[STRIKE]This is[/STRIKE]
I then visited a[FONT="] lake called “Deep
Lake”, located not far from
downtown [/FONT][STRIKE]of[/STRIKE][FONT="] Kazan.[/FONT]
[FONT="]3. Briefly discuss, based on your on-site observations, what is "being done" or "should be done" to minimize the problems you observed.[/FONT]
[FONT="]B. Many of you are in programs or are doing research related to diffuse pollution. Please describe in a paragraph why diffuse pollution control is related to work you are currently doing or plan to do after you graduate.[/FONT]
