Water Pollutants?

Question

I need a list of Water pollutants for a water project I'm doing in school, please help!!!

Answer 1

insecticides and herbicides,
a huge range of organohalide and other chemicals
bacteria, often is from sewage or livestock operations;
food processing waste, including pathogens
tree and brush debris from logging operations
VOCs (Volatile Organic Compounds, industrial solvents) from improper storage
heavy metals including acid mine drainage
acidity caused by industrial discharges (especially sulfur dioxide from power plants)
chemical waste as industrial by products
fertilizers, in runoff from agriculture including nitrates and phosphates
silt in surface runoff from construction sites, logging, slash and burn practices or land clearing sites

Answer 2

With all that has been said so far, in the replies to your question. None have mentioned simple plastics. Over the generation that plastics have been used, they have entered our waters, washed upon our shores, they have been ground to minuscule bits and pieces. They have found there way into organs of fishes and the birds of the world. Plastics will be part and parcel, of the cause and ultimate extermination of edible fish as we know them, with-in the next 50 years. The oceans may never recover, if steps are not taken today...just scoop the sand from you seaside sand castle and look! the oceans are full of floating bits and pieces, the new killer plankton...

Hope this helps, keep on researching and good luck...

Answer 3

Many causes of pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates. In excess levels, nutrients over stimulate the growth of aquatic plants and algae. Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters.
This, in turn, proves very harmful to aquatic organisms as it affects the respiration ability or fish and other invertebrates that reside in water.
Pollution is also caused when silt and other suspended solids, such as soil, washoff plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains. Under natural conditions, lakes, rivers, and other water bodies undergo Eutrophication, an aging process that slowly fills in the water body with sediment and organic matter. When these sediments enter various bodies of water, fish respirationbecomes impaired, plant productivity and water depth become reduced, and aquatic organisms and their environments become suffocated. Pollution in the form of organic
material enters waterways in many different forms as sewage, as leaves and grass clippings, or as runoff from livestock feedlots and pastures.

Answer 4

The most common pollutant in rural areas are nitrates. These are from over-fertilization, failed septic systems, and animal feed lots. Also in agricultural areas, surface water contaminants include phosphates and herbicides and pesticides.

For point source chemical contamination, common contaminants include volatile hydrocarbons such as those found in leaking gasoline tanks: benzene, ethylbenzene, toluene, and xylenes (BTEX).

Also, there could be chlorinated hydrocarbon compounds such as perchloroethylene (from a drycleaner).

OR, you could be dealing with natural contaminants such as arsenic and mercury.

Answer 5

just some could be .. Metals: lead (Pb) - this could effect the techniques and valuable apprehensive device mercury (Hg) - this could effect something from creative and prescient to retardation, and crippling, this turn into additionally why years in the past there have been "mad hatters" there turn into mercury cutting-edge interior the materical that formed the hats cadmiun (Cd) - this reasons brittle bones to the element the place your legs can't delay your top physique Non Metals: nitrate (NO3) - this could effect babys it turns to nitrite of their intestines and prevents the oxygen Selenium (Se) - this reasons blindness, garlic breath, and dying quite often animals get this from flowers arsenic (As) - reasons pink scaly skin, an infection and dying inorganic water pollutants can even have comparable consequences as man made organics
