An ergonomic assessment of upper limb musculoskeletal risk factors using revised strain index (RSI) and threshold limit value for hand activity level (TLV- HAL) in hand-swen shoe workers

Toxicity and hazard assessment of dioctyl terephthalate (DOTP) was performed in acute, subacute, and chronic experiments, and its principal toxicometry parameters were determined.It was found that on single exposure DOTP exhibits low toxicity and hazard. No resorptive and irritant effects on skin and mucous membrane of eyes were detected in animal experiments. The single inhalation exposure threshold limit value was set at 300 mg/m3, based on the results of monitoring of the functional state of the central nervous system and myocardium and hematological parameters.Thirty-day subacute experiments (oral administration, inhalation exposure, and skin applications) revealed no accumulation of the compound.Four-month chronic exposure to DOTP aerosols (concentration 96,8 mg/m3) caused disorder of the functional state of the central nervous system and myocardium, changes in the hematological and biochemical parameters, gas and acid-base status of the blood, and morphological changes in the lungs and heart. Embryotoxic, genotoxic and gonadotoxic effects were not detected.The chronic inhalation exposure threshold limit value for DOTP (Limch) was set at 18,6 mg/m3, and the concentration of 3,4 mg/m3 was found to be ineffective.The maximum allowable concentration of DOTP in the air of the working area was set at 3,0 mg/m3, hazard class 3.

The American Conference of Governmental Industrial Hygienists 1971 standard threshold limit value (TLV) of 0.55 mgHg/m of air was found to be exceeded frequently in a sample of 60 dental operatories in San Antonio, Texas. Significant differences in contamination among laboratories were found, among sites within operatories, and among times of day, correlated with kilograms of mercury used, average number of amalgams inserted per day, age of operatories, height of carpeting pile, cleaning methods, frequency of cleaning, and general lack of routine monitoring and use of bioassays. Recommendations for control of metallic mercury contamination in dental operatories are offered.
