PART 1 : DETERMINATION OF NON-VOLATILE MATTER, GRAVIMETRIC METHOD.

试验方法。第1部分：不挥发性物质的测定。

The results showed that sevoflurane was the most prevalent volatility halogenate anesthetics and had the highest concentration at sampling areas. All study hospitals exceeded the exposure limit for halogenate anesthetics (2ppm) recommended by NIOSH (National Institute for Occupational Safety and Health).The median level of N2O at the two medical centers was 1.87 ppm. Although regional hospitals seldom use N2O, its concentration was very high (median 120.85 ppm).

结果显示，Sevoflurane为使用最多之挥发性卤化麻醉剂，环境浓度亦最高，各医院均有高於NIOSH对於单一卤化麻醉剂暴露建议值(2ppm)的情形；医学中心笑气浓度之中位数为1.87 ppm，然区域医院虽极少使用笑气，环境中位数浓度高达120.85 ppm，有管路或开关阀泄漏之可能性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
