What is the permissible levels of each pollutants?
Permissible_levels_of_emission_of_gases_in_pollution_check
each gas emitted from pollution are:
nitrogen oxides-5%
fine particulate matter 1%
voc(volatile organic compounds like chloroflourocarbon)-2%
carbon monoxide-0.3%
sulphur dioxide-8%
air toxics:
acroleine-0.01%
formaldehyde-3%
coolants like ozone(o3)-3%
note- might change depending upon your country this is valid for india, russia, singapore, malaysia and sri lanka. if you are in usa everything is same except fine partilculate matter 5%. according to 2011 conference.

What is the abbreviation for the pollution watchdog agency?
The official pollution watchdog agency is the Environmental Protection Agency (EPA)
What is the major source of human-caused air pollution?
Burning of fossil fuel such as coal, wood, etc.
Household fuels like kerosene, gas, etc.
Motorised vehicles driven by petrol, diesel, etc.
Number of chemical industries also release chemicals into the atmosphere.
What are reasons for land pollution?
Pollution is the contaminants in the environment that is harmful to all living things. The reasons for having pollution are discharging harmful gases from motor vehicles, chemical plants, plastics and improper disposal of waste.
Do animals have a part in pollution?
Any living organism whose constituting cells can suffer from chemically induced mutations of DNA may be affected by pollution.
Modified DNA translates in modified proteins, which as an effect of mutation may have lost their functionality, hence affecting the functions they were supposed to serve.
How does recycling and reusing reduce pollution?
How does water become polluted after rain?
It gets sucked up by plants or goes into the ocean or goes into sewers.
What gas often creates more air pollution?
"Air pollution" is not just one gas. It can be any number of different gasses or particulates.
For example, smoke from coal power plants contains large amounts of Sulphur Dioxide (SO2.) You could also include chloroflourocarbons, nitrous-oxides, ground-level ozone, etc.
What is the rain that is affected by pollution and harms trees and lakes?
Commonly called: "Acid Rain."
How can thermal inversion make air pollution worse?
The air becomes stiller, hence the air becomes murky because dust and pollutants are no longer lifted from the surface. This can become a problem in cities where many pollutants exist. During a severe inversion, trapped air pollutants form a brownish haze that can cause respiratory problems.
What things cannot be patented?
things that are patented by someone else, something that already exists without a patent but we use or see in everyday life and things that are not patented but are used by other corperations. otherwise any invention or product can be patented under the grounds that the name isn't already used or is too common to be patented.
Water pollution is the introduction into fresh or ocean waters of chemical, physical, or biological material that degrades the quality of the water and affects the organisms living in it. This process ranges from simple addition of dissolved or suspended solids to discharge of the most insidious and persistent toxic pollutants (such as pesticides, heavy metals, and nondegradable, bioaccumulative, chemical compounds).

Reusable waste are items that have been discarded that can be used again. Bottles and cans are examples of reusable wastes. Recycling facilities can thoroughly sanitize reusable waste so that they can be reused by manufacturing facilities.
Why are trees a renewable resource and how this resource can be maintained?
people dig the ground then they put the tree
How is bacteria removed from sewage?
If untreated sewage was allowed to flow into rivers, it would soon become a serious health hazard. Raw sewage is screened to remove large objects and then allowed to settle in special tanks. The sludge that settles is often sold as fertilizer or turned into fuel, which can be used in the sewage works. The impure water is allowed to filter through grovel beds which contain microbes which feed on the bacteria in the water and destroy them. At the same time the water becomes aerated by absorbing oxygen from the air. The water can then be returned to the river.
What are the negative effect of thermal polution?
All thermal power plants reject low quality heat to the environment, whether to a lake, river, or ocean, or to the atmosphere through cooling towers. Fossil fuelled plants emit carbon dioxide and sulfur dioxide.
What is pollution doing to the world?
When you are driving in your car and there is a load of rubbish coming out of your exhaust (Witch is carbon dioxide) this CO2 will rise up to the earths atmosphere and stop heat from getting out so the heat can get in but not out and that heat that is getting trapped inside the earths atmosphere will melt the polar ice caps and flood the earth so in other words we are all going to die if we don't do something about it!
How is segregation of waste done?
Waste is segregated accoding to the following types: Biodegradable waste Recyclable waste Non-recyclable waste Biodegradable waste can be again of different types: food waste, dry leaves, etc. for composting and reuse. Recyclable waste can be of different types, such as: paper, wood, cotton, reusable hardware, glass, metal scrap, etc Non-recyclable waste includes polythenes and plastics which cannot be treated for reuse.
Is pollution of Hawaii decreasing?
Yes. Pollution is everywhere that cars travel around frequently. Although Hawaii is a paradise place, it also has some pollution in the air. Especially in Honolulu, the main city, where all the cars are.
What did people learn from the Chernobyl disaster?
Human error at any level of technology development or use is the biggest cause of major accidents with the technology, regardless of type of technology.
What was the cause of the Chernobyl nuclear disaster?
After the steam explosion which blew the top of the reactor off, the graphite moderator was exposed to air, and as it was hot enough it started to burn. Decay heat from the fuel would have contributed to the high temperature as well. Graphite burns well in air, as barbecues demonstrate.
See Wikipedia 'Chernobyl disaster' for more information on the development of the disaster.
Does thermal pollution affect fish?
Fish have adapted to living in a certain temperature range & can't do things to adapt. For example, tropical fish can only survive in the warm tropical waters while fish like salmon thrive in the colder waters nearer the poles.
