The amendment imposes a ban on dumping waste material into the sea. Although much care has been taken to reduce its toxic and pathogen content, employees engaged in biosolids application in the farm fields and residents near the sludge-applied fields have reported health problems after its application. This research explores temporal variation in the quality of bioaerosols generated from class B biosolids applied to farm fields at different places around Bowling Green, Ohio. Two types of air samplers, Microflow sampler (single stage sampler) and Andersen’s six stage sampler were used to collect the bioaerosols. The combined data of both samplers were used to study the temporal variation of bioaerosols during and after class B biosolid application to farm fields. All of the data show higher numbers of bacteria colonies collected from the downwind direction than from upwind. Compared to the data collected on the day of application, total bacteria, Staphylococcus aureus, and gram-negative bacteria were elevated 2 days after biosolids application. Levels decreased to control level 13 days after application, except for Staphylococcus aureus, which was highest 13 days after application. It can be concluded that pathogenically nontreated class B biosolids are capable of generating potential pathogens in the air. This increased content might be responsible for reported health problems in nearby residents during the post-application period. eAlso there is a possibility that the finer particles, which constitute approximately 50% of the total bioaerosols generated from the fields, can be transported some distance away from the class B biosolids-applied field. These finer particles containing pathogens might be responsible for health problems in residents a mile away from the field. However, further research is necessary to come to a definite conclusion in this regard. This research will increase awareness regarding the possible prohibition of class B biosolids in favor of class A biosolids, which are biologically treated sludge that contain comparatively fewer bacteria. 2005-11-09 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1131322484 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1131322484 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
