OBJECTIVE: To investigate the effects of CS(2) occupational exposure on thumbprint and intelligence.
METHODS: According to the monitoring results of CS(2) concentration, which were got at various workplace in chymic fiber factory, the workers were divided into three groups including the low-concentration group (TWA < 5 mg/m(3)), the high-concentration group (TWA >or= 5 mg/m(3)) and the control group. The method of cluster sampling was used respectively. 139, 129 and 327 people were taken at random from three groups and they were given thumbprint and intelligence examinations through following three methods, including MMPI, SCL-90 and SPM.
RESULTS: MMPI test showed that Hy, Pa, Pt, Sc positive rates in the low-concentration group were 7.19%, 2.16%, 26.62% and 10.07%, Hs, D, Hy, Pa, Pt, Sc, Ma, Si positive rates in the high-concentration group were 32.56%, 8.53%, 9.30%, 24.81%, 2.33%, 42.64%, 15.50%, 5.43% and 6.20%. There was a significant difference with the control group (Hs, D, Hy, Pd, Pa, Pt, Sc, Ma, Si was 14.07%, 2.14%, 2.14%, 14.07%, 0.00%, 17.74%, 3.67%, 1.22%, 1.22% respectively). The differences of Hs, Pt positive rates between high-concentration and low-concentration group were significantly. SCL-90 showed that the total positive rate in the low concentration and the high concentration groups was 15.8% and 20.2%. The positive rate of the basic factors were significantly different among the low-concentration group, the high concentration group and the control group while there was no significant difference in the positive rate between the high concentration and low concentration group. SPM test found that the positive rates of the intelligence in the low concentration group and the high concentration group were 35.1% and 35.7% respectively and the control group (15.1%) was significantly different from low-concentration and high concentration group. Moreover, there was no obvious difference between high-concentration and the low-concentration group. The intelligence damage was associated with the length of CS(2) occupational exposure and the correlation coefficient had statistical significance.
CONCLUSION: The low-concentration CS(2) occupational exposure could affect personality and intelligence, and the degree of this influence is associated with the length of CS(2) occupational exposure.
