Transfer of Frictional Contact Derived Phthalates from Pad Surface Enhances Dermal Exposure.

A significant risk of elevated health risk is dermal exposure to chemicals derived from object surface contact. A higher accumulation of phthalates was observed in rubbing fabrics with identical surface roughness to U-shape fabrics. The estimated transfer rate of bis ester obtained from rubbing friction on the pad surface over 8 hrs was higher than those for gas-phase emission and sweat transfer. These findings showed that dermal frictional contact with pad product's surface was a critical exposure route.

Assessment of dermal exposure to pesticides among farmers using dosimeter and hand washing methods.

The use of personal protective equipment among Indian farmers is also negligible due to their affordability to obtain the same. Very little research has been done to determine an exposure assessment method based on dermal penetration of pesticide residues in mosquitos. A field study was done in Rangareddy district, Telangana, Southern India, to determine the dermal exposure based on dosimeter and hand washing techniques, in order to determine pesticide residue contamination by dermal exposure along with detailed field observations and pesticide control procedures. 0 to 0. 6, 0 to 0. 3 bcg, with a change observed in exposure levels as measured dermal exposure values varying from 0 to 0. 629 bcg. The results of the present report confirm the operator's increased exposure to organophosphate pesticides has increased, and they point to the use of protective equipment, particularly those that emphasize dermal exposure mitigation.

Analysis of the absorption kinetics following dermal exposure to large doses of volatile organic compounds.

After being exposed to a high dose of volatile organic compounds, a mathematical model was developed to investigate the skin penetration of volatile organic compounds. The process was divided into two steps, separated by the time it took for excess chemicals to be depleted from the skin surface by the time it took for excess chemicals to be depleted from the skin surface by the time it took. After the compound dissipated from the stratum corneum's surface, the application of Laplace transform techniques resulted in transient profiles. The decrease in the flow rate reduced the total number of VOC absorption and reduced the time required for the surface fluid to evaporate, but increased the total number of VOC permeated and reduced the time required for the surface fluid to fade.
