 What is the ozone depletion? What are the main chemicals that accelerate the ozone depletion?

 What are the main indoor air pollutants?

Answer 1

Main indoor air pollutants:

Carbon Monoxide (CO) , Lead (Pb) , Nitrogen dioxide (NO2) , formaldehyde

Ozone depletion = The gradual decrease in the ozone layer in the stratosphere due to greenhouse gases like CO2, CFCs , etc which gives rise to more amount of UV rays infiltrating the earth's atmosphere and reaching earth's surface is called ozone layer depletion.

Ambient air pollutants:

particulate matter (PM) , nitrogen dioxide (NO2), Sulphur dioxide (SO2), Ozone (O3)

sources = waste incineration, burning of fuels, vehicle fuel combustion, industrial wastes, etc.

TCLP is toxicity characteristic leaching procedure is a methodology by which amount of leaching is estimated due to accumulated landfill.

EPCRA = Emergency Planning and Community Right to know Act (1986)

a guideline to help communities in case of hazardous chemical emergencies
