And should water bottles and the like be proscribed, or just taxed to death in order to discourage use?
because liberals still buy them
Why are manufactures still allowed to produce pollutants like plastic bottles and bags?
What happens to the pollutants when waste water is “cleaned up”?
A. The pollutants are still here on earth; they have just been removed from the water.
B. Some pollutants are recycled or decomposed by natural processes.
C. Both of these may be correct.

What pollutants are released during the combustion of oil?
And what are the consequences?
Sulfur dioxide and nitrogen dioxide are the major ones in terms of long-term environmental damage. They acidify rain, which does wide-ranging harm. See first link for an in-depth discussion of all the nasty effects.
Other particulates (like elemental carbon), polynuclear aromatic hydrocarbons, and carbon monoxide are a problem primarily at the burn site - they’re a health hazard to people exposed to the smoke.

Comprising over 70% of the Earths surface, water is undoubtedly the most precious natural resource that exists on our planet. Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent: it is essential for everything on our planet to grow and prosper. Although we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organisms
are dying at a very alarming rate. In addition to innocent organisms dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes. In order to combat water pollution, we must understand the problems and become part of the solution.
CAUSES OF POLLUTION
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

ADDITIONAL FORMS OF WATER POLLUTION
Three last forms of water pollution exist in the forms of petroleum, radioactive substances, and heat. Petroleum often pollutes waterbodies in the form of oil, resulting from oil spills. The previously mentioned Exxon Valdez is an example of this type of water pollution. These large-scale accidental discharges of petroleum are an important cause of pollution along shore lines. Besides the supertankers, off-shore drilling operations contribute a large share of pollution. One estimate is that one ton of oil is spilled for every million tons of oil transported. This is equal to about 0.0001 percent. Radioactive substances are produced in the form of waste from nuclear power plants, and from the industrial, medical, and scientific use of radioactive materials. Specific forms of waste are uranium and thorium mining and refining. The last form of water pollution is heat. Heat is a pollutant because increased temperatures result in the deaths of many aquatic organisms. These decreases in temperatures are caused when a discharge of cooling water by factories and power plants occurs.

Demonstrators Protest Drilling
Oil pollution is a growing problem, particularly devestating to coastal wildlife. Small quantities of oil spread rapidly across long distances to form deadly oil slicks. In this picture, demonstrators with "oil-covered" plastic animals protest a potential drilling project in Key Largo, Florida. Whether or not accidental spills occur during the project, its impact on the delicate marine ecosystem of the coral reefs could be devastating.

Oil Spill Clean-up
Workers use special nets to clean up a California beach after an oil tanker spill. Tanker spills are an increasing environmental problem because once oil has spilled, it is virtually impossible to completely remove or contain it. Even small amounts spread rapidly across large areas of water. Because oil and water do not mix, the oil floats on the water and then washes up on broad expanses of shoreline. Attempts to chemically treat or sink the oil may further disrupt marine and beach ecosystems.
CLASSIFYING WATER POLLUTION
The major sources of water pollution can be classified as municipal, industrial, and agricultural. Municipal water pollution consists of waste water from homes and commercial establishments. For many years, the main goal of treating municipal
wastewater was simply to reduce its content of suspended solids, oxygen-demanding materials, dissolved inorganic compounds, and harmful bacteria. In recent years, however, more stress has been placed on improving means of disposal of the solid residues from the municipal treatment processes. The basic methods of treating municipal wastewater fall into three stages: primary treatment, including grit removal, screening, grinding, and sedimentation; secondary treatm
How Many Contaminants Other Than Dust , Pollen And Fog Are Identified As Air Pollutants?
How Many Contaminants Other Than Dust , Pollen And Fog Are Identified As Air Pollutants? Which Are Of Natural Origin.
Everything that floats in the air is a potential contaminant including mercury. There are more than 104 elements in the periodic table. All are potential contaminants.
These elements can combine to form many compounds. Each compound is a contaminant. I do not know the exact number of possible contaminants.
what are some types of Pollutants dangerous to the environment?
Can you name some of the worst kinds of Pollutants in the environment? Thanks
Also if anyone knows any decent sources to get information on Pollutants that would be great, as i’m trying to learn more.
Although there are many types of pollution and sources, industry has contributed its share over the last couple hundred years. Industrial pollution can include air pollution like carbon dioxide, monoxide and ozone; water pollution in the form of petroleum spillage, radiation and heat; and other pollutants like heavy metals. These pollutants make their way into delicate ecosystems and damage wildlife and plant life, as well as public health.
1. Carbon Dioxide - Industrial pollution contributes to the total amount of carbon dioxide in the atmosphere which could be significant or insignificant to the environment depending on the scientist. However, carbon dioxide can still be a danger to health. In addition to displacing oxygen, carbon dioxide can cause headaches, drowsiness and the inability to concentrate.
2. Ozone - Ozone or O3 can be a dangerous form of air pollution if it comes in contact with living things. It’s formed by organic gases reacting with nitrogen oxides with sunlight as a catalyst. Ozone is a form of industrial pollution that results from petroleum processing and storage. Ozone can cause breathing difficulties and long term lung tissue damage. It can also damage rubber and some types of plastic. The prevention of excess organic and nitrogen oxide emissions from power plants and refineries is one way to limit ozone reactions.
3. Oil Spills - An oil spill is a type of industrial accident in which oil spills or leaks from a source into the environment. An oil tanker running aground and leaking oil into the ocean is an example. Bad weather, human error and terrorism are the usual causes, although some industries may dump oil illegally to cut costs. Oil spills have detrimental effects on wildlife and the oil may stay in the ecosystem for decades, even after cleanup.
4. Heavy Metals - Heavy metals include lead, mercury, arsenic, zinc, copper and are a danger to the environment and public health. Although many heavy metals are the result of industry, automobiles have begun contributing to this type of pollution too through road runoff. In humans, lead, arsenic and mercury can be very dangerous, causing behavioral and internal problems. Unfortunately, when metals get into the environment, aquatic life tend to be more susceptible because of their close proximity to metals that may have settled along the waterbed.
5. Water - Sometimes, industry can cause water pollution that can damage many types of ecosystems. Aquatic fish and plant life, animals, and humans are all affected. Polluted water can also reach lakes, rivers, streams and groundwater, making the affected area very large. Petroleum, radiation and heat pollution are among the primary causes of industrial water pollution
Why would pollutants from a new point source be less likely to show up in the Great Lakes?
this question is for my science homework?
Why would pollutants from a new point source be less likely to show up in the Great Lakes?
well im from michigan and letting you know the great lakes are already polluted but they would be less likely just because there arent many large rivers leading to the great lakes .
Why would pollutants from a new point source be less likely to show up in the Great Lakes?
this question is for my science homework?
Why would pollutants from a new point source be less likely to show up in the Great Lakes?
It would all depend on where the point source is! The great lake drainage basin is fairly small when compared the the world as a whole.
Only if the point source is near the lakes, will you will see it in there.
What are the diff types of water pollutants?
What are the diff types of water pollutants?
Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, groundwater).
Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging either to individual species and populations, but also to the natural biological communities.
Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.
Causes of water pollution
The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water, and what is a contaminant.
Oxygen-depleting substances may be natural materials, such as plant matter (e.g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species.
Many of the chemical substances are toxic. Pathogens can produce waterborne diseases in either human or animal hosts. Alteration of water’s physical chemistry includes acidity (change in pH), electrical conductivity, temperature, and eutrophication. Eutrophication is an increase in the concentration of chemical nutrients in an ecosystem to an extent that increases in the primary productivity of the ecosystem. Depending on the degree of eutrophication, subsequent negative environmental effects such as anoxia (oxygen depletion) and severe reductions in water quality may occur, affecting fish and other animal populations.
Pathogens
A manhole cover unable to contain a sanitary sewer overflow.Coliform bacteria are a commonly-used bacterial indicator of water pollution, although not an actual cause of disease. Other microorganisms sometimes found in surface waters which have caused human health problems include:
Burkholderia pseudomallei
Cryptosporidium parvum
Giardia lamblia
Salmonella
Novovirus and other viruses
Parasitic worms (helminths).
High levels of pathogens may result from inadequately treated sewage discharges. This can be caused by a sewage plant designed with less than secondary treatment (more typical in less-developed countries). In developed countries, older cities with aging infrastructure may have leaky sewage collection systems (pipes, pumps, valves), which can cause sanitary sewer overflows. Some cities also have combined sewers, which may discharge untreated sewage during rain storms.
Pathogen discharges may also be caused by poorly-managed livestock operations
Chemical and other contaminants

Organic water pollutants include:
Detergents
Disinfection by-products found in chemically disinfected drinking water, such as chloroform
Food processing waste, which can include oxygen-demanding substances, fats and grease
Insecticides and herbicides, a huge range of organohalides and other chemical compounds
Petroleum hydrocarbons, including fuels (gasoline, diesel fuel, jet fuels, and fuel oil) and lubricants (motor oil), and fuel combustion byproducts, from stormwater runoff
Tree and bush debris from logging operations
Volatile organic compounds (VOCs), such as industrial solvents, from improper storage. Chlorinated solvents, which are dense non-aqueous phase liquids (DNAPLs), may fall to the bottom of reservoirs, since they don’t mix well with water and are denser.
Various chemical compounds found in personal hygiene and cosmetic products
Inorganic water pollutants include:
Acidity caused by industrial discharges (especially sulfur dioxide from power plants)
Ammonia from food processing waste
Chemical waste as industrial by-products
Fertilizers containing nutrients–nitrates and phosphates–which are found in stormwater runoff from agriculture, as well as commercial and residential use
Heavy metals from motor vehicles (via urban stormwater runoff) and acid mine drainage
Silt (sediment) in runoff from construction sites, logging, slash and burn practices or land clearing sites
Macroscopic pollution—large visible items polluting the water—may be termed "floatables" in an urban stormwater context, or marine debris when found on the open seas, and can include such items as:
Trash (e.g. paper, plastic, or food waste) discarded by people on the ground, and that are washed by rainfall into storm drains and eventually discharged into surface waters
Nurdles, small ubiquitous waterborne plastic pellets
Shipwrecks, large derelict ships
