美国食品药品监督管理局最近提出了监管电子雾化装置上市的PMTA法规，法规要求在美国上市的电子雾化装置产品必须审查化学品成份，添加剂，尼古丁浓度，毒理学特征和对∏人体健康的影响，从而获№得上市许可。同样，英国的电子雾化装置制造商或进口商也必须严←格遵守产品安全法规，对产品成份和释放物进行毒理学测试，兴奋剂、色素和维生素添加剂受到严格监管，以评估对人体健康的影』响。

According to Premarket Tobacco Product Applications (PMTA) For ENDS, FDA requires manufacturers and importers submit testing reports of chemicals, additives, Nicotine concentration, and a full toxicological and pharmacological assessment for health risks of new tobacco products. In EU countries, such as UK, manufacturers and importers of E-Cigarettes also need to submit test reports of components, ingredients, additives, and toxicological assessment, according to EU Tobacco Products Directive (TPD) on E-Cigarettes, to assess the public health risks.

因此，全球电子雾化装置市场对电子烟产品的监管均日趋严格，对产品进行毒理学评估成为大势⊙所趋。天鉴检测机构以国际认可的加拿大卫生部毒理测试为标准，已开发出完善的电子雾化装置体外毒理学检测方法，面向电子雾化装置各类企业，提供电子雾化装置烟油及气溶胶的体外毒理学评估▓测试服务。

Under the background of more strict supervision of E-Cigarettes marketing in global market, toxicological assessment of ENDS is essential for E-Cigarettes products marketing. As one of the earliest independent testing organizations in E-Cigarettes test field, SKYTE has developed complete in vitro toxicological assessment methods for E-Cigarettes, according to Health Canada official methods.
