普罗维登斯,R.I. [威尼斯人娱乐场信誉官网] — A team of researchers from 威尼斯人娱乐场信誉官网's 公共卫生学院, 威尼斯人娱乐场信誉官网工程学院 寂静的春天学院 found that simple air filtration devices called Corsi-Rosenthal盒子 are effective at reducing indoor air pollutants.
这项研究, which analyzed the effectiveness of Corsi-Rosenthal盒子 installed at the 公共卫生学院 to help prevent the spread of COVID-19, 这是第一个同行评议的盒子对室内污染物的功效研究吗, 据作者所说.
“研究结果表明，一种廉价的, easy-to-construct air filter can protect against illness caused not only by viruses but also by chemical pollutants,布劳恩说. “This type of highly-accessible public health intervention can empower community groups to take steps to improve their air quality 和 therefore, 他们的健康.”
Corsi-Rosenthal盒子, 或数据集, 可以从五金店找到的材料:四个MERV-13过滤器, 布基胶带, 一个20英寸的盒子风扇和一个纸板箱. 作为 全校性的项目, 箱子由学生组装 和 campus community members 和 installed in the 公共卫生学院 as well as other buildings on the 威尼斯人娱乐场信誉官网 campus.
评估立方体去除空气中化学物质的功效, Braun 和 his team compared a room’s concentrations of semi-volatile organic compounds before 和 during the box’s operation.
的 结果发表在《威尼斯人娱乐场信誉官网》杂志上 & 技术, showed that Corsi-Rosenthal盒子 significantly decreased the concentrations of several pfa 和 邻苯二甲酸盐 in 17 rooms at the 公共卫生学院 during the period they were used (February to March 2022). pfa, 一种合成化学物质，存在于包括清洁剂在内的一系列产品中, 纺织品和电线绝缘, 下降40% ~ 60%; 邻苯二甲酸盐, commonly found in building materials 和 personal care products, were reduced by 30% to 60%.
