Module 7 Flashcards
Air Pollution
The introduction of chemical, particular matter, or microorganisms into the atmosphere at concentrations high enough to harm plants, animals, and materials such as building, or to alter and ecosystem.
Air Pollution
The introduction of chemical, particular matter, or microorganisms into the atmosphere at concentrations high enough to harm plants, animals, and materials such as building, or to alter and ecosystem.
Sulfurs Dioxide
A corrosive gas that comes primarily from combustion of fuels such as coal and oil, including diesel fuel from trucks
Haze
Reduced Visibility
Photochemical oxidant
A class of air pollutants formed as a result of sunlight acting on chemical compounds such as nitrogen oxides and sulfur dioxide
Smog
A type of air pollution that is a mixture of oxidants and particular matter
Lead
A trace metal that occurs naturally in rocks and soils, is present in small concentrations in coal and oil and is in neurotoxin.
Hydrocarbons
Pollutant compounds that contain carbon hydrogen bonds, such as gasoline and other fossil fuels, lighter fluid, dry cleaning fluid, oil based paint, and perfumes
Primary Pollutant
A polluting compound that comes directly from the smokestack, exhaust pipe, or natural emission source
Secondary Pollutant
A primary pollutant that has undergone transformation in the presence of sunlight, water, oxygen, and or other compounds
Photochemical smog
Smog that is dominated by oxidants such as ozone (Los Angelos Type Smog
)
Sulfurous Smog
Smog dominated by sulfur dioxide, sulfate compounds, and particulate after. (London-Type smog)
Evaporate
The process of converting from a liquid to a gas or vapor
Sublimate
The process of converting a solid to a gas or vapor
Formaldehyde
A naturally occurring compound that i used as a preservative and as and adhesive on plywood and carpeting
Theremal inversion
An atmospheric condition in which relatively warm later of air at mid-altitude covers a layer of cold dense air below
Inversion layer
The player of warm air that traps emissions in a thermal inversion
PM10
Particles smaller than 10um are called Particulate matter -10 and are not filtered out by the nose and throat and can be deposited deep within the respiratory tract.
PM2.5
Particles of size 2.5um and smaller can travel further within the respiratory tract and are of even greater health concern
Indoor Air pollutants
Compounds that adversely affect the air quails in buildings and structures
Asbestos
A long, thin, fibrous silicate mineral with insulating properties, which can cause cancer when inhaled
Radon 222
A radioactive gas that occurs naturally from the decay or uranium and is an indoor air pollutant
Sick Building syndrome
A buildup of toxic pollutants in weatherized spaces such as newer buildings in the developed world
Vapor Recovery nozzle
A device that prevents VOCs from escaping into the atmosphere while a person is fueling their vehicle
Catalytic COnverter
A device that uses chemical to convert pollutants such as nitrogen oxide and carbon monoxide to nitrogen gas and carbon dioxide
Scrubber
A device that uses a combination of ;one and or water to separate and remove particles from industrial exhaust streams
Electrostatic Precipitator
A device that removes particulate matter by using an electric charge to make particles coalesce so they can be removed from the exhaust stream
PH
The relative strengthen of acids and bases in a substance. It is logarithmic scale, meaning that each number on the scale represents a change by a factor of 10
Acid
a substance that contributes hydrogen ions to a solution
Base
A substance thar contributes hydroxide ions to a solution
Acid Rain
Precipitation high in sulfuric acid and nitric acid. (Acid deposition)
Noise Pollution
Unwanted sound that interferes with normal activities that is loud enough to cause health issues including hearing loss
Decibel A scale
A logarithmic scale that measures both the loudness of sound and the frequency of
