数十亿人无法获得安全的饮用水和干净的.
沸水是常见的解决方案,但可以加剧室内空气污染的固体燃料.

研究的目的:

为了模拟减少腹疾病和增加家庭空气污染 (HAP) 之间的健康权衡,从饮用水沸.
在低收入环境中分析水污染,沸效率和炉类型的场景.

主要方法:

从HAP和腹来计算残疾调整寿命年 (DALYs) 的变化.
使用乌干达和越南作为案例研究,考虑各种水质,沸和炉子场景.

主要成果:

沸显著降低了腹DALYs,特别是高风险的水和高效的沸.
增加的HAP DALYs在具有高基线空气污染的环境中是有限的.

Constant Pressure Calorimetry

Constant Pressure Calorimetry

Calorimetry is a technique used to measure the amount of heat involved in a chemical or physical process or to measure the heat transferred to or from a substance. The heat is exchanged with a calibrated and insulated device called the calorimeter. Calorimetry experiments are based on the assumption that there is no heat exchange between the insulated calorimeter and the external environment. The well-insulated calorimeters prevent the transfer of heat between the calorimeter and its external...
