Pollutions Flashcards
contamination of indoor or outdoor environment by any chemical
air pollution
invaluable tool in providing evidence for establisihing casual associations between air pollution and many health outcomes
epidemiology of air pollution
examine health effects related to short-duration exposures
short-term air pollution studies
examine health effects related to long-term or chronic exposure to air pollution
long-term air pollution studies
techniques employed to reduce or eliminate the emission into the atmosphere of substances that can harm the environment or human health
air pollution control
aims to reduce or eliminate pollutants at the source before they enter the atmosphere
pollution prevention
replacing polluting fuels
fuel switching
modifying industrial processes
industrial process changes
reducing overall energy consumptions
improving energy efficiency
devices are installed on emission sources to capture or treat pollutants before they are released into the atmosphere
pollution control device
use electrical charges to attract and remove particulate matter from exhaust streams
electrostatic precipitators
wet scrubbers use water or a liquid spray
scrubbers
these fabric filters trap particulate matter by forcing the exhaust stream through woven bags
baghouses
installed in vehicle exhaust systems
catalytic converters
the primary purpose is to safeguard public health
focus on protection
set specifically to protect human health
health-based objectives
focus on maintaining good visibility by limiting pollutants that reduce atmospheric clarity
visibility-based objectives
refers to presence of radioactive materials and the environment at levels that are harmful
radiation pollution
is the invinsible energy emited by certain types of unsable or radioactive atoms
radiation
to measure not only individual data but also the amount of radiation entering the body
exposure assessment
essential to assess individual exposure to radiation
personal monitoring
can cause health problems for people and wildlife, both on land and in the sea
noise pollution
most common source of noise pollution
transportation noise
comes from factories that is a type of noise
industrial noise
noise from loud music
recreational noise
from appliances
household noise
determines the level of potential harm
intensity
the length of time a person is exposed to noise
duration of exposure
how often a person is exposed to noise
frequency
