本文对冬季长途航运客轮的卫生状况进行了调查。结果表明,客轮舱室内空气污染严重,细菌总数、CO_2超标率分别为23.64％、18.63％。舱室档次越低,CO、CO_2污染越严重,有乘客吸烟的舱室CO、CO_2浓度明显高于无乘客吸烟的舱室。CO_2浓度舱内>过道>甲板。乘客安静状态下(0～7时)舱内CO_2浓度最高,而CO浓度较低。舱室内温度按等级依次为五等>四等>三等>二等。

Investigation on Health Status of Longdistance Passenger Ships in Winter

An investigation on health status of long-distance Passenger shiPs was conducted in winter,The results showed that cabin air Pollution is heavy in winter with the results of total number of bacteria 23.64% and carbon dioxide 18.63% beyond the fixed limit rate.The lower cabin class is,the heavier air Pollution with carbon monoxide and carbon dioxide is.Carbon monoxide Concentration and carbon dioxide concentration in smoking cabin are very higher than thoes in nonsmoking cabin and car-bon dioxide concentration in cabin is the highest but carbon monoxide cocnetration in cabin is the lowest when passengers are in quiet state(0~7 o'clock),The order of carbon dioxide concentration from high to low is cabin,gallery,deck and temperature in cabin is fifth class,fourth class,third class,second class.
