Default 冬季室内空气危机四伏

天气逐渐变冷,人们越来越多地在温暖如春的室内活动,室内潜伏着的“隐形杀手”应该引起人们的 重视。
冬季门窗紧闭,室内有害物质的浓度会渐渐增高。装饰装修造成的室内环境污染危害会更严重,光波炉。室内的污染源主要是甲醛、苯、氨和放射性物质。人在短时间内吸收高浓度的苯,会出现中枢神经系统麻醉的症 状,轻者头晕、头痛、恶心、乏力、意识模糊,重者会出现昏迷以至呼吸循环衰竭而死亡。氨无色却具有强烈的刺 激性气味,常附着在皮肤黏膜和眼结膜上,从而产生刺激和炎症,减弱人体对疾病的抵抗力。装修中散发出来的氡 与其他有毒气体不同的是,氡看不见,嗅不到,即使在氡浓度很高的环境里,人们对它也毫无感觉。然而氡对人体 的危害却是终身的,它是导致肺癌的第二大因素。
冬季走进各公共场所,一股热气就会扑面而来。长时间置身其中,便会觉得有一种窒息的感觉。客运站、洗浴中心 、宾馆等公共场所的二氧化碳含量时有超标。据专家介绍,二氧化碳的含量是判断空气污浊与否的综合性间接指标 ,公共场所的二氧化碳含量应小于等于0.15%。
每到冬季,气候非常干燥,室内缺少湿润、洁净的空气。据医生介绍,在干燥的冬季,白喉、流感、百日咳、脑膜 炎、哮喘、支气管炎等的发病率显著增加,导致上述疾病的原因很多,除了冬季温度偏低、温差变化大导致人体抵 抗力下降外,光波炉厂家,还有如下两方面的原因:其一,环境湿度过低使流感病毒和致病力强的革兰氏阳性菌繁殖速度加快,而且随粉尘 扩散,引起疾病流行。其二,环境湿度过低可使人的呼吸系统抵抗力下降,诱发和加重呼吸系统疾病。因此,从某 种意义上说,克服干燥就是克服流行病。冬季,红外线光波炉,居室小气候的最佳温度为18℃-25℃,湿度45%-65%RH。
应对冬季空气污染
加湿器可将湿度控制在最适合人体的湿度范围内,既可抑制病菌的滋生和传播,还可提高免疫力。
要注意合理通风。写字楼和百货商场等公共场所要注意增加室内新风量。家庭每天开窗换气不少于两次,每次不少 于15分钟,光波炉批发。用煤炉取暖和使用燃气热水器的家庭更要注意安装通风装置。此外要利用室内空气净化设备消除室内环境污染, 提高室内空气质量。要多做室外活动,少去人多的公共场所。
