Examination and Research Development of IoT-Based Air Quality Monitoring and Assessment Technology**

大气污染物的主要排放源包括氮氧化物(NOx)、颗粒物(PM)、一氧化碳(CO)、挥发性有机化合物(VOCs)、重金属和硫氧化物(SOx)，它们对环境空气质量有害，对公众的安全和健康造成直接和严重的危害。因此，有必要建立最先进的监测系统，及时报告污染物排放水平，评估对空气质量的影响和人体暴露的风险。然而，当前的空气监测面临着新的挑战，因为加拿大和世界各地的排放上限法规越来越严格，要求更好的监测覆盖面和大数据量的实时监测，这也给数据分析带来了新的挑战。尤其是加拿大最大的空气采样、监测和管理行业之一Consul-Air Inc.正面临着这些挑战，目前迫切需要提升其在空气排放和环境空气质量管理方面的技术和服务，以进一步扩大其全球业务。基于领航与申请人实验室相同的研发兴趣和互补的专业知识，该合作项目探索基于微处理器和微型传感器开发的基于物联网(IoT)的高性价比空气污染监测系统。选定要监测的环境参数包括主要冰盖、气象条件以及现场的噪音，这些参数实时传输到服务器。专业人员和决策者可以评估正在进行的现场条件对环境的影响，跟踪人类暴露在哪些污染物中，并采取行动，及时保护公众或工人免受伤害。拟议的系统将与Consul-Air Inc.一起在加拿大的真实工业现场进行测试和验证。结果还可以进一步用于改进新的空气质量评估和预测技术。******

Major emission source of criteria air pollutants (CAPs) including nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), volatile organic compounds (VOCs), heavy metal, and sulfur oxides (SOx) are detrimental to the ambient air quality, and they can cause immediate and serious damage to the public safety and health. Therefore, it is essential to have the state of art monitoring system to timely report the pollutant emission levels and assess the impacts on the air quality and the risks of human exposure. However, current air monitoring is facing new challenges as the emission cap regulation in Canada and worldwide is getting more strict and require better monitoring coverage and real-time monitoring with large volume of data, this also brings new data analysis challenges. Particularly, one of the largest industries in Canada in air sampling, monitoring and management, Consul-Air Inc., is facing these challenges and is currently in an urgent need of advancing its technology and services on air emission and ambient air quality management to further extend its business globally. Based on the same R&D interests and complementary expertise between Consul-Air and the applicant's Lab, this partnership project explores cost-effective IoT (Internet of Things)-based air pollution monitoring system developed based on microprocessor and micro sensors. The environmental parameters selected to be monitored include the major CAPs, meteorological conditions as well as noises at the site, which are transmitted to the server in real time. Professionals and decision makers can assess the environmental impacts of the ongoing site condition and track what pollutants the human is exposed to and take actions to protect public or workers from harms in a timely manner. The proposed system will be tested and validated at real industrial sites in Canada together with Consul-Air Inc. The results can be also further employed to advance new air quality assessment and prediction techniques. ******
