Exam Playful child Afebrile Normal growth chart Normal HEENT except some crusting nasal
discharge Occasional coarse upper respiratory sounds
Why are children not small adults?

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

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,
nitro-PAH and heavy metals PM2.5 invoke an inflammatory response and
contain probable lung carcinogens (IARC)

Units at Compressor Stations & Gas Metering Stations Releasing Emissions into the Air Compressor Engines
Compressor Blowdowns
Condensate Tanks
Storage Tanks
Truck Loading Racks
Glycol Dehydration Units
Amine Units
Separators
Fugitive Emission Sources
90% of individuals reported experiencing odor events from these facilities
From survey conducted by Earthworks

Sample Air Test
What is elevated in this sample and what does the elevation mean?
724.260.5504
![Page 13: Case Study #2](https://reader036.fdocuments.in/reader036/viewer/2022062813/5681666d550346895dda071b/html5/thumbnails/13.jpg)
Important Variables with Air Testing Type of air monitor: summa canister,
H2S monitor, 24 hour personal air monitor
Direction of wind, weather pattern that day
Location sampled Beware of sample contamination
especially with summa and what each air monitor tests
