为了解证券交易场所空气溶血性链球菌（ＨＳ）的污染状况，对三家证券交易场所空气溶血性链球菌（ＨＳ）及细菌总数（ＢＴ）在不同时间段进行采样检测，结果表明，证券交易场所空气ＨＳ浓度营业后明显高于营业前，且有随着人均容积减小而升高的趋势。三家证券交易场所空气ＨＳ浓度均值分别为７２ＣＦＵ／ｍ３、６４ＣＦＵ／ｍ３、７９ＣＦＵ／ｍ３，其中超过３６ＣＦＵ／ｍ３的检测点分别占８７．５％、７５．０％、８２．５％。三家证券交易场所空气ＢＴ的浓度均值均未超过２０００ＣＦＵ／ｍ３。说明证券交易场所ＨＳ污染比ＢＴ严重。ＨＳ比ＢＴ更能反映生物性污染状况。建议将证券交易场所纳入《公共场所卫生管理条例》的管理范畴，并制订相应的空气ＨＳ卫生标准。
In order to understand the contamination status of hemolytic streptococcus (HS) in the stock exchange, the samples of airborne hemolytic streptococcus (HS) and total bacteria (BT) in the three stock exchanges were sampled and tested at different time intervals. The results showed that the stock exchange The concentration of air HS was significantly higher than that before business, and it increased with the decrease of per capita volume. The average concentration of air HS in the three stock exchanges was 72CFU / m3, 64CFU / m3 and 79CFU / m3, respectively, of which the test points of more than 36CFU / m3 accounted for 87.5%, 75.0% and 82.5% respectively. The average concentration of air BT in the three stock exchanges did not exceed 2000CFU / m3. HS stock exchange that BT pollution than serious. HS better reflects the status of biological contamination than BT. It is suggested that the stock exchange should be included in the management of “Health Management Regulations in Public Places” and the corresponding air HS health standards shall be formulated.
