We investigated the genotoxicities or mutagenicities of 2 chemicals (octane and tetrasodium pyrophosphate) with limited toxicological data in spite of their common usage based on Ames reverse mutation test. In this test, treatment of 2 chemicals at each five dose did not induce mutagenicity in Salmonella typhimurium TA98, TA100, TA1535, TA1537, and in Escherichia coli WP2uvrA with and without metabolic activation. These results indicate that 2 chemicals do not have mutagenic potentials under the conditions examined in each study. Despite these results, it can affect by inducing inhalation, skin or eye contact, ingestion, and have affected central nervous system as a target organ. It is thus necessary to prepare the local exhaust system and personal protective equipments. Based on this study, we suggest that future studies should be directed toward chronic inhalation, carcinogenic test and so on.
我们研究了两种化学物质(辛烷和焦磷酸四钠)的遗传毒性或致突变性,尽管它们根据 Ames 反向突变试验在使用上很常见,但关于它们的毒理学数据却很有限。在该试验中,在每个五个剂量下处理这两种化学物质,均未在鼠伤寒沙门氏菌 TA98、TA100、TA1535、TA1537 和大肠埃希氏菌 WP2uvrA 中诱导出致突变性,无论是否有代谢激活。这些结果表明,在每项研究中检查的条件下,这两种化学物质均没有致突变潜能。尽管如此,它们仍可能通过吸入、皮肤或眼睛接触、摄入而产生影响,并以中枢神经系统为靶器官产生影响。因此,有必要准备局部排气系统和个人防护设备。基于这项研究,我们建议未来的研究应针对慢性吸入、致癌性试验等方向进行。
