COMPOSTING
(Environmental & Health Issues)
Presence of human pathogen
Transmittal of human pathogen are added to a compost pile
pathogen reduction occurs in larger compost piles due to self heating
common pathogen: potting mixes
pathogen increment occurs in smaller compost piles
active compost can cause allergic response
How to overcome?
odors are minimized when sufficient oxygen
combination of engineering controls, work practices and PPE can reduce occupational exposure
Practice good personal hygiene when handling
avoid certain input to compost piles
raw poultry
meat waste
pet feaces
keep the system hot enough
agitation of the compost
Health effects
general health complain
skin diseases
respiratory system
excessive odor
nausea
muscosal membrane irritation
Airborne particles emitted
includes live/dead bacteria, fungi, virus, toxins etc
cause symptoms and illness
microorganisms are adsorbed onto dust particles
sensitive to some bioaerosols due to repeated exposure
bioaerosols are microbial particles
concentration of bioaerosols downwind of outdoor composting facility are elevated
Infections
gastric
aspergillosis
