2. INTRODUCTION

Particle pollution comes from many different type of sources. Fine
particle (2.5 micrometers in diameter and smaller) include power plants,
industrial processes, vehicle tailpipes, wood stoves, and wildfires.
Coarse particles (between 2.5 and 10 micrometers) come from
crushing and grinding operations, road dust, and some agricultural
operations.
Particle pollution is linked a number of health problems, including
coughing, wheezing, reduced lung function, asthma attacks, heart
attacks and strokes. It also is linked to early death.
Some people may be at greater risk from particle pollution. They
include:
People with cardiovascular disease (diseases of the heart and blood
vessels).
People with lung disease, including asthma and COPD.
Children and teenagers.
Older adults.
Research indicates that obesity or diabetes may increase risk.
New or expectant mothers may want to take precaution to protect the
health of their babies.
Volatile organic compounds (VOCs) definitions: A VOCs is any organic
compound having an initial boiling point less than or equal to 250℃
(480℉) measured at a standard atmospheric pressure of 101.3 kPa.
VOCs play an important role in indoor and outdoor air pollutants.
Vehicular and industrial emissions are the major sources of outdoor VOCs.
Indoor sources are quite numerous including combustion product, cooking,
construction materials, furnishings, paints, varnishes and
adhesives and caulks, office equipment and consumer products.
Concentrations of many VOCs are consistently higher indoors (up to ten
times higher) than outdoors.
