Foot exposure

The measurement of foot exposure to pesticides is not commonly performed in worker exposure studies. However, the measurement of foot exposure can be accomplished by either using socks as a foot dosimeter or by washing the foot using similar procedures to those used for the face wipe. 

Foot exposure of workers can be measured by using socks as dosimeters or anklet dosimeters worn under ordinary socks. Usually an ordinary sock or anklet bought at a retail store will suffice for the dosimeter. As with whole-body dosimeters, the sock material should be 100% cotton but may be other materials. Pre-washing the socks or anklets prior to use in the field may be necessary if analytical interferences are found in the sock material. The socks or anklets should be put on the volunteer using procedures similar to those already described in order to avoid cross-contamination of the sock dosimeter.

Acute oral LD50 deaths usually occurred between 3 and 20 h after treatment. Remission took up to 12 days (Hudson et al. 1984) Percutaneous LD50 for 10- to 11-month-old drakes after a 24-h dermal foot exposure. Deaths occurred between 6 and 22 h after treatment remission took up to 5 days (Hudson et al. 1984)... 

The alimentary symptoms may be overshadowed by neuromuscular dysfunction, accompanied by signs of motor weakness that may progress to paralysis of the exterior muscles or the wrist (wrist drop), and less often, of the ankles (foot drop). Encephalopathy, the most serious result of lead poisoning, frequendy occurs in children as a result of pica, ie, ingestion of inorganic lead compounds in paint chips this rarely occurs in adults. Nephropathy has also been associated with chronic lead poisoning (147). The toxic effects of lead may be most pronounced on the developing fetus. Consequendy, women must be particulady cautious of lead exposure (148). The U.S. Center for Disease Control recommends a blood level of less than 10 p.m per 100 mL for children.

In a study where both peripheral and central nervous system effects were measured in rats co-exposed to u-hexane and toluene (Pryor and Rebert 1992), toluene exposure at 1,400 ppm for 14 hours a day for 9 weeks prevented the peripheral neurotoxicity (decreased grip strength and nerve conduction velocities) caused by exposure to 4,000 ppm 77-hcxanc alone. There was no reciprocal action of 77-hexane on the motor syndrome (shortened and widened gait and widened landing foot splay) and hearing loss caused by toluene. Brainstem auditory response amplitudes were decreased by 77-hcxanc, co-exposure to toluene did not block this effect.
