Children’s Susceptibility To Air
Hazards
 Have
increased respiratory rate and
breathe in more (i.e. more toxins) per
body weight than adults
 Play vigorously for long time periods
 Developmental stages predispose them
to activities and behaviors conducive to
environmental exposures
 Have little knowledge or awareness of
environmental hazards
SOUTHWEST PENNSYLVANIA ENVIRONMENTAL HEALTH PROJECT
Known Emissions from
Compressors

Compressors and motors on the drilling and
production sites, injection well disposal sites
and along pipelines release combustion
products and volatile organic hydrocarbons
into the air and degrade the air quality

These combustion products also combine
with the volatile organic chemicals in the
presence of heat and sunlight to produce
ground level ozone

Potential for Air Pollution- VOC
& PM 2.5




Ground level ozone exacerbates underlying
asthma and COPD and causes lung injury
PM2.5 when inhaled lodge in the deep lung
(bronchioles and alveoli)
PM2.5 carbonaecous core adsorbs PAH, nitroPAH and heavy metals
PM2.5 invoke an inflammatory response and
contain probable lung carcinogens (IARC)
