摘　　要：目的了解南昌市新居甲醛污染现状,分析其影响因素,为新居装修及防治甲醛污染提供参考依据。方法采用国家标准方法,对2021年1—12月随机选取的南昌市新装修完成的95家房屋进行甲醛采样和检测,以国家标准规定的0.08mg/m^(3)为限值判断是否超标。结果共采集样本188个,其中超标样本有132个,超标率70.2%,甲醛浓度为0.023~0.986mg/m^(3),甲醛平均浓度为0.213 mg/m^(3)。室内甲醛浓度与检测时的温度、湿度、装修完成时间、装修豪华程度和通风条件均存在正相关(均P<0.05)。结论甲醛作为室内最主要的空气污染物之一,严重危害人体健康,应考虑多种因素对甲醛释放量的影响,采取相应的措施,从而降低接触甲醛的危害。Objective To understand the current situation of formaldehyde pollution in new houses in Nanchang and analyze its influencing factors,so as to provide scientific basis for the decoration and prevention of formaldehyde pollution in new houses.Methods Totally 95 newly renovated houses randomly selected in Nanchang City from January to December 2023 were sampled and tested for formaldehde by the national standard method,then the 0.08 mg/m^(3)stipulated in the national standard was used as the limit to judge whether it exceeds the standard.Results There were a total of 188 samples,of which 132 exceeded the standard,exceeding the standard rate of 70.2%,formaldehyde concentration was 0.023-0.986 mg/m^(3),the average concentration of formaldehyde was 0.213 mg/m^(3).Indoor formaldehyde concentration was positively correlated with temperature,humidity,decoration completion time,decoration luxury and ventilationconditions(all P<0.05).Conclusion As one of the most important indoor air pollutants,formaldehydeis seriously harmful to human health,and a variety of factors on the impact of formaldehyde release should be considerd to take the corresponding measures,so as to avoid the harm of exposure to formaldehyde.
