摘　　要：目的了解三门峡市某区宾馆客房室内空气中甲醛污染状况及其影响因素。方法检测2019年1—12月三门峡市某区43家宾馆客房室内空气中甲醛浓度,根据GB 37488—2019《公共场所卫生指标及限值要求》计算甲醛超标率,并对结果进行分析和评价。结果不同通风条件下的甲醛浓度超标率比较,差异有统计学意义(P<0.05),随着通风条件变好甲醛浓度超标率呈下降趋势(P<0.05);不同装修后时间下的甲醛浓度超标率比较,差异有统计学意义(P<0.05),随着装修后时间的增加甲醛浓度超标率呈下降趋势(P<0.05);不同时段气温下的甲醛浓度超标率比较,差异有统计学意义(P<0.05),随着气温的增加甲醛浓度超标率呈上升趋势(P<0.05);复杂装修的甲醛浓度超标率高于简单装修,差异有统计学意义(P<0.05)。结论三门峡市某区宾馆客房室内甲醛污染较严重,通风条件差、装修后时间短、气温升高以及装修程度复杂是造成其甲醛浓度超标的主要原因。Objective To investigate the formaldehyde pollution and its influencing factors in indoor air of hotel rooms in a district of Sanmenxia City.Methods The formaldehyde concentration in the indoor air of 43 hotel rooms in a district of Sanmenxia City was detected from January to December 2019.The formaldehyde overstandard rate was calculated according to GB 37488—2019 Public Health Index and Limits Requirements,and the results were analyzed and evaluated.Results The formaldehyde concentration under different ventilation conditions which statistically difference(P<0.05),with good ventilation conditions of formaldehyde concentration which is on the decline(P<0.05);The formaldehyde concentration under different time after decorating which statistically difference(P<0.05),with the increase of time after decorating formaldehyde concentration which is on the decline(P<0.05);Temperatures in the different periods of formaldehyde concentration which statistically differenc(P<0.05),with the increase of the temperature of formaldehyde concentration which is on the rise(P<0.05);Complex which is higher than simple decoration,decoration of formaldehyde concentration difference was statistically significant(P<0.05).Conclusion The indoor formaldehyde pollution of hotel rooms in a district of Sanmenxia City is serious.The main reasons for the excessive formaldehyde concentration are poor ventilation conditions,short decoration time,rising temperature and complex decoration degree.
