Figure 3. Coveralls, gloves, location of exposure pads, and section samples.
2. The subjects had to spray under the extreme heat of the sun causing them to
perspire and wet the coveralls. This removed the markings thus making it
difficult to cut the sections properly. Mud/dirt especially at the leg portions
obscured the markings as well.
3. Tile pads made of surgical gauze were inadequate as exposure pads.
4. Difficulty in the proper placements of the pads was encountered, especially
on the gloves. Also the tape of choice (leukoplast) was unsatisfactory
resulting in the loss of one exposure pad and others were almost detached.
5. The sectioning of the samples was done while on the subjects' bodies since
it was difficult to have them remove the co-,-ralls due to wetness of the
cloth especially on the trunk portions.
6. Environmental parameters such as temperature. humidity, wind speed and
direction were not properly recorded.
