This paper presents some recent development in this area , focusing on soil contamination by polycyclic aromatic hydrocarbons ( pahs ) , which are notorious for their toxicity , teratogenicity and carcinogenicity 多环芳烃由于其毒性、致癌性和致畸性成为环境中一类重要的污染物。
Head of toxicology at chang gung memorial hospital lin jie - liang said that bacteria in food can cause food poisoning , but contamination with mold has different effects that are possibly carcinogenic 长庚医院毒物科主任林杰梁：细菌污染会造成细菌性食物性中毒，假如是霉菌污染，可能就是致癌性风险在里面。
They were registered in hong kong in november 2000 and june 2001 respectively . both avandia and actos had been subject to two - year carcinogenicity studies on rodents and subsequent clinical trials on humans before their registration applications were tendered to the ppb for consideration 有关公司为这两种药物向药剂业及毒药管理局提出申请注册前，已就这两种药物在老鼠身上进行为期两年的致癌性研究，其后也在人体进行临?测试。
Dh and ppb have always been aware of possible carcinogenicity of any new drug , including ppar agonists , in rodents and humans , and have therefore been requesting drug companies , in seeking registration of drugs belonging to the ppar agonist class , among others , to provide reports on rodent carcinogenicity study and subsequent clinical trials on humans for consideration by ppb ?生署和药剂业及毒药管理局一直留意任何新药(包括ppar促效剂)用于老鼠和人类身上可能出现的致癌性，并因此要求药业公司在申请注册属于ppar促效剂的药物时，须另就有关药物在老鼠身上进行致癌性研究以及其后在人体进行临?测试，提交报告予药剂业及毒药管理局考虑。
Due to the carcinogenicity and the considerable impact on our environment and ecosystems , polychlorinated dibenzo - para - dioxins ( dioxins ) and their structurally similar compounds such as polychlorinated dibenzo - para - furans ( furans ) and polychlorinated biphenyls ( pcbs ) have become concerns to public health 摘要由于多氯戴奥辛（以下称戴奥辛） ，与其化学结构类似的化学物质，如多氯夫喃（以下称夫喃）与多氯联苯等，被发现在动物实验中有极强的致癌性及对环境的卫击，在公共卫生上引起很大的关切。
From different points of view of the epidemiology , cytogenetics , molecular biology , experimental pathology and preventive medicine , this study revealed and proved that the genotoxicity and carcinogenesis existed in the drinking pond water in the high incidence area of live cancer in guangxi , indicated the feasible preventive and interruptive methods , too 从分析流行病学，细胞遗传毒理学、分子生物学、实验病理学和预防医学的不同角度，揭示和论证了广西某肝癌高发区居民饮用塘水的基因毒性和致癌性，提出了切实可行的预防和阻断措施。
The study recommended that due to the prevalence of tumor found in rodents during that study , and hence safety concern about long - term use of such substances on humans , rodent carcinogenicity study for at least two years should be done for drugs belonging to the ppar agonist class prior to the conduct of clinical studies on humans 基于在研究之中，老鼠身上出现肿瘤的比率令人关注到人类长期服用会产生安全问题，因此研究建议属于ppar促效剂的药物必须先在老鼠身上进行最少两年的致癌性研究，然后才可在人体进行临?研究。
