Pollution

Pollution is the process of giving out contaminants such as smoke and carbon dioxide, and too much of a certain product such as light, heat and sound that both cause harm to the environment.

What happens because of air pollution?

Asked by Wiki User

Acid rain is some case, death in the case of high exposure to carbon monoxide in enclosed areas. Catarrh in some cases. CFC cause ozone layer depletion which in turn causes skin cancer and other health hazards as a result of exposure to Ultraviolet rays.

How do you stop car pollution in our ocean?

User Avatar

Asked by Wiki User

build a house that filters the ocean soaking up garbage and letting water back out im not really smart but i think we should put sump pumps or somthing with the same effect that will suck up the water and run it throw a filter and then return it back to the ocean so all the little fishes can swim again and we should lock ever little dirt bag that litters i our water for life and we can come up with our own group and name it water is in us foundation were we send out mags

What problem is air pollution to cities?

User Avatar

Asked by Wiki User

The most common "city pollution" people think of is Photochemical Smog. I quote: "Photochemical smog is an atmospheric condition that produces severe eye irritation and poor visibility, to name just two of the effects. Three ingredients -- energy from a light source (ultraviolet), hydrocarbons, and nitrogen oxides -- are needed for photochemical smog to be formed. Two of those components are produced through the burning of fossil fuels, most notably automobiles. Photochemical smog is also sometimes known as "oxidizing smog", in that it has a high concentration of oxidizing agents. Ozone is a common oxidizing agent found in photochemical smog. Another type of smog, "reducing smog", has high concentrations of sulfur dioxide, which is a reducing agent. Its presence has historical significance in studies done in places like London, which used sulfur-containing coal as its main energy source."

Basically your car burns fuel in air/oxygen. We all know CO2 is one product of this combustion, but depending on the air to fuel (A/F) ratio, other compounds are also formed. The perfect stoichiometric point for gasoline is 14.7; or 14.7 pounds of air to 1 pound of gasoline. Any more air and it's a lean ratio, any less and it's a rich ratio.

If the combustion was perfect, you would get your hydrocarbon gasoline combustion converted into heat, energy, CO2, N2, and H2O. But the combustion never is perfect, so you also get:

  • Carbon monoxide (CO) is a poisonous gas that is colorless and odorless.
  • Hydrocarbons or volatile organic compounds (VOCs) are a major component of smog produced mostly from evaporated, unburned .fuel.
  • Nitrogen oxides (NO and NO2, together called NOx) are a contributor to smog and acid rain, which also causes irritation to human mucus membranes.

NO2 is the main culprit of Photochemical Smog. It can also cause acid rain and other problems. NOx can react with atmospheric oxygen to produce tropospheric Ozone (very bad). Unlike the the ozone up in the stratosphere protecting us, ground level ozone is smog, and harmful.

Your car's catalytic converter is an amazing invention from the 1970s that helps reduce these emissions. The reduction catalyst is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the NOx emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example:

2NO => N2 + O2 or 2NO2 => N2 + 2O2

Who pollutes and why?

User Avatar

Asked by Wiki User

Many different entities contribute to pollution, including industries, transportation, agriculture, and households. The reasons behind pollution can vary depending on the sector. Industries may release pollutants as a byproduct of production processes. Transportation contributes to pollution from vehicle emissions. Agricultural practices such as pesticide and fertilizer use can contaminate water and air. Lastly, individual households can generate pollution through waste disposal and energy consumption choices.

Are dragonflies harmful to the environment?

Asked by Wiki User

No, dragonflies are not harmful to the environment. In fact, they are beneficial insects as they help control populations of mosquitoes and other flying insects. Dragonflies are also important pollinators and indicators of the overall health of aquatic ecosystems.

How much pollution does a nuclear power plant give off in 5 days?

User Avatar

Asked by Wiki User

Nuclear power plants do not release pollutants into the atmosphere while generating electricity. However, there could still be indirect emissions associated with the mining and processing of uranium fuel, construction, and transportation. These emissions are relatively small compared to fossil fuel power plants and can vary depending on the specific plant and its operations.

Pollutant from motor car exhaust that causes mental disease is?

User Avatar

Asked by Wiki User

one of the main pollutants from motor car exhaust that can contribute to mental disease is fine particulate matter (PM2.5). These tiny particles, measuring 2.5 micrometers or smaller, can be inhaled into the body and can penetrate the bloodstream, potentially affecting the brain and causing cognitive impairments or mental health disorders.

What are the 5 most polluting things?

User Avatar

Asked by Wiki User

The five most polluting things are:

  1. Fossil fuel combustion, which releases greenhouse gases and air pollutants like carbon dioxide and nitrogen oxides.
  2. Industrial processes, including chemical manufacturing and mining, which generate toxic air and water emissions.
  3. Deforestation and land use changes, which contribute to loss of biodiversity and release large amounts of carbon dioxide into the atmosphere.
  4. Agriculture, particularly livestock production, which emits methane and contributes to water pollution through the use of fertilizers and pesticides.
  5. Waste disposal, such as improper management of solid waste and wastewater, which can contaminate soil, water, and air.

How does pollution affect trade?

User Avatar

Asked by Wiki User

Pollution can negatively affect trade in several ways. It can lead to health and environmental concerns, which can result in trade restrictions or bans on certain products. Pollution can also damage infrastructure, such as ports and transportation networks, impeding the movement of goods. Additionally, pollution can harm the reputation of a country or region, reducing consumer confidence and impacting trade relationships.

What is NPS pollution?

User Avatar

Asked by Wiki User

NPS (Nonpoint Source) pollution refers to the contamination of water bodies, such as rivers, lakes, and oceans, by pollutants that cannot be traced back to a single source. It happens when rain or snowmelt carries pollutants, such as fertilizers, pesticides, oil, and sediment, from the land into water bodies. The sources of NPS pollution are widespread and include agricultural activities, urban runoff, forestry practices, and construction activities. These pollutants can have harmful effects on aquatic ecosystems and human health.

User Avatar

Asked by Wiki User

Water pollution is a growing concern that requires immediate action. To mitigate this issue, several measures can be taken. Firstly, stricter regulations must be enforced to control industrial waste disposal and encourage the use of cleaner technologies. Secondly, public awareness campaigns should be conducted to educate people about the harmful effects of water pollution and the importance of responsible waste management. Lastly, investment in wastewater treatment plants and infrastructure improvement is crucial to filter out pollutants before they enter water bodies. By implementing these steps, we can halt water pollution and safeguard our vital water resources.
