Abstract As part of an industry wide study in the fumigation industry, industrial hygiene evaluations were conducted at two structural fumigation facilities in Florida during July of 1990; difficulty was noted with National Institute for Occupational Safety and Health (NIOSH) Method 2520 for methyl-bromide (74953). Sampling results indicated that methyl bromide breakthrough had occurred. Some of the backup tubes contained greater amounts of methyl-bromide than the front sampling tubes. Several problems were discovered when reviewing the method. These included reduced adsorption capacity at high humidity, difficulty in preparing standard solutions, sample instability, decreasing recovery as the loading decreased, and insufficiently low quantitation limit. Several modifications were offered for methyl-bromide sampling.
