[The rervising of biological exposure index for carbon disulfide exposuring].

Objective: To study the biological exposure index of carbon disulfide in China.

Methods: High-performance liquid chromatography (HPLC) was used to detect the levels of 2-thiothiazolidine-4-carboxylic acid (TTCA) in the urine of the workers after working shift end, Gas chromatography was used to detect the concentrations of the carbon disulfide in the workplace air. The relationship between the urine TTCA levels and the concentrations of the carbon disulfide was analyzed, the biological exposure index and judgement result from PC-TWA were compared.

[Carbon disulfide exposure level of workers in a chemical fiber industry].

Objective: To investigate the exposure levels of carbon disulfide (CS(2)) for a chemical fiber industry.

Methods: The concentration of CS(2) was monitored in representative workshops and types of work, and the datas of that over the years were collected.

Results: The short-term exposure concentration of CS(2) about 80% of the type of work was less than or equal to 10 mg/m(3), which of more than 90% was less than or equal to 20 mg/m(3).

[Effects of carbon disulfide on cardiovascular system of workers occupationally exposed to carbon disulfide].

Objective: To study the effects of long-term exposure to carbon disulfide (SC(2)) on cardiovascular system of workers.

Methods: The concentrations of CS(2) were detected in the representative workshops with different exposure levels. The indicators related to cardiovascular system were tested in 633 workers occupationally exposed to CS(2), which included blood pressure, electrocardiogram, blood routine (blood RT), cholesterol (TCHO), triglyceride (TG) and so on.

[Analysis of musculoskeletal disorders, work load and working postures among manufacturing workers].

Objective: To analyze the distribution of the musculoskeletal disorders, work load and working postures in different factories, gender, education levels, age and working years among manufacturing workers.

Methods: In a cross-sectional study of 5134 manufacturing workers in 12 factories, the morbidities for musculoskeletal disorders in one year period were measured with questionnaires.

Results: The morbidities for musculoskeletal disorders in body sites: waist, neck, shoulder, wrist, ankle/feet, knee, hip/buttocks and elbows were 59.
