| Abstract |
Personal exposure and area air monitoring for Bacillus thuringiensis (Bt) was conducted to determine occupational and general public exposure potential to Bt. Portable sampling pumps with membrane filters (MF) were used to conduct the sampling. Analysis of the MF for Bt involved microbial culture techniques with the presence of toxin crystal formation confirming identification as Bt. This paper presents the exposure sampling results, discusses problems encountered when conducting microbial sampling with membrane filters, and discusses modifications to resolve the problems. Occupational exposure results ranged from 0 to 5600 colony forming units (CFU) of Bt/m3. General public Bt exposure results ranged from 0 to 1600CFU/m3. |
