Today we review research from Denmark which examined the direct and indirect impacts for people in residences near biodegradable waste sites. Results indicate increased frequency of respiratory and sensory irritation symptoms directly related to dose and exposure.
Key Quotes:
“A large number of potentially hazardous pollutants are emitted during handling, storage, treatment and disposal of agricultural, animal and municipal biodegradable wastes”
“Environmental exposures play an important role in the genesis of respiratory, sensory and general health symptoms among residents exposed to low-to-moderate air pollution from biodegradable wastes”
“In some cases, the health effects of air pollution seem to be indirect, relayed through stress-related mechanisms. However, we found evidence of direct effects for some of the symptoms as well”
“Residential NH3 exposure was associated with increased frequency of four symptoms, including “eyes itching, dryness or irritation” and “cough”.. Odor annoyance mediated the effect of exposure on cough and three sensory irritation symptoms.”
“Significant associations were also found between individual NH3 exposures and ‘‘chest wheezing or whistling’’ and ‘‘runny nose’’”
“This study provides support for the existence of indirect associations between residential exposures to low-to-moderate air pollution from wastes and symptoms, as well as direct dose-response associations for some of the symptoms.”
