household activities, factories, agriculture and transport

. Once they have been released into the environment, the concentration of some pollutants is reduced by dispersion, dilution, deposition or degradation.

Which is the best example of a point source pollution?

Examples of point sources include

sewage treatment plants

; oil refineries; paper and pulp mills; chemical, automobile, and electronics manufacturers; and factories. Regulated pollutants from point sources include wastes, soils, rocks, chemicals, bacteria, suspended solids, heavy metals, pesticides, and more.

What is NPS or non point source pollution comics?


Nonpoint

source pollution: pollutants from a diffuse ( spread wide ) source rather than one specific source. Usually nonpoint source pollution is transported by storm water run offs from large land areas which may contaminate the surface and ground water over a large area.

What are 3 categories of NPS?

Based on the number that is given, the customer is then placed into one of the three categories:

Promoter, Passive, or Detractor

. These categories describe how the customer feels about the product or service, their loyalty to the company, and whether or not they would recommend it.

How is NPS calculated?

Your Net Promoter Score is calculated by:

Subtracting the percentage of detractors from the percentage of promoters

. … For example, if 10% of respondents are detractors, 20% are passives and 70% are promoters, your NPS score would be 70-10 = 60. Your NPS could range from -100 to 100.

  • Transportation Emissions. …
  • Agriculture Side-Effects. …
  • Home Heating. …
  • Home Cooking. …
  • Volcano Eruptions. …
  • Forest Fires. …
  • Tobacco Smoke.

What are the natural source of pollution?

Dust from places without vegetation,

methane gas emitted by the digestion of food by animals

, like cows and cattle, radon gas from radioactive decay, wildfires, releasing smoke and carbon monoxide into the atmosphere and volcanic activity, producing sulfur, chlorine, and ash particulates are a few examples of pollution …

What are the 10 types of pollution?

Major forms of pollution include

air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, and water pollution

.

Which of these sources of pollution is most difficult to regulate?

The U.S. Environmental Protection Agency (EPA) has identified six criteria pollutants: carbon monoxide, nitrogen dioxide, sulfur dioxide,

ozone

, lead, and particulates (aerosols). Of these six pollutants, ozone has proved the most difficult to control.

Which is point source pollution?

It is pollution that comes from many places, all at once. The United States Environmental Protection Agency (EPA) defines point source pollution as

any contaminant that enters the environment from an easily identified and confined place

. Examples include smokestacks, discharge pipes, and drainage ditches.

What type of pollution that comes from multiple sources?


Nonpoint source pollution

is difficult to control because it comes from many different sources and locations. Most nonpoint source pollution occurs as a result of runoff. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with.

How can we prevent point source pollution?

  1. Keep litter, pet wastes, leaves and debris out of street gutters and storm drains—these outlets drain directly to lake, streams, rivers and wetlands.
  2. Apply lawn and garden chemicals sparingly and according to directions.

Which source of water pollution is difficult?


Nonpoint source pollution

, which is the leading cause of water pollution in the U.S., is usually much more difficult and expensive to control than point source pollution because of its low concentration, multiple sources, and much greater volume of water.

Is DDT a point source pollution?

Point source pollution is defined as

coming from a single point

, such as a factory or sewage treatment plant. … Most of the DDT originated from the Montrose Chemical Corporation manufacturing plant located in Torrance, California.
