Chen XQ, Tan XD: [Studies on DNA damage in workers with long-term exposure to lower concentration of carbon disulfide]. Zhonghua Yu Fang Yi Xue Za Zhi. 2004 Jan;38(1):36-8.
OBJECTIVE: DNA damage in human buccal cells of workers occupationally long-term exposed to carbon disulfide (CS (2)) was monitored with comet assay. METHODS: Ninety workers exposed to CS (2) were randomly selected as exposure group from a large-scale chemical fiber manufacturer in Hubei and 81 workers not exposed to CS (2) as control group. DNA damage in their buccal cells was detected with comet assay. RESULTS: Rate of DNA tail was 0.51% in exposure group, significantly higher than that in control group (0.23%), with very statistical significance. Rate of DNA tail was 0.50% in male exposure group and 0.56% in exposure group with short length of employment, significantly higher than that in control group (0.08% and 0.25%, respectively). Multivariate unconditional logistic regression analysis showed that possibility of DNA damage was significantly higher in exposure group than that in control group (P < 0.05). CONCLUSION: Long-term exposure to lower concentration of carbon disulfide could cause certain damage to human buccal cell DNA. |
