Design and implementation of a wearable environmental monitoring system

Abstract

In recent years, air pollution has become a critical social problem because harmful materials can cause disease and death to humans as well as damage to other living organisms, including food crops, or the natural or built environment. In 2014, the World Health Organization (WHO) reported that around 7 million people died in 2012 as a result of exposure to air pollution, that is, one in eight of total global deaths, which indicates that air pollution is now the world's largest single environmental health risk [1, 2]. WHO also estimates that indoor air pollution in households cooking over coal, wood and biomass stoves was linked to 4.3 million deaths. In the case of outdoor air pollution, WHO estimates that 3.7 million deaths worldwide occurred as a result of sources of pollution from both urban and rural areas.
