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

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、硫氧化物（SOx）等标准空气污染物（cap）的主要排放源对环境空气质量有害，对公共安全和健康造成直接和严重的损害。因此，有必要拥有先进的监测系统，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，目前的空气监测面临着新的挑战，因为加拿大和世界范围内的排放上限监管越来越严格，需要更好的监测覆盖面和大数据量的实时监测，这也带来了新的数据分析挑战。特别是，加拿大最大的空气采样、监测和管理行业之一的康索尔空气公司（Consul-Air Inc.）正面临着这些挑战，目前迫切需要提高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。基于相同的研发兴趣和申请人实验室的互补专业知识，该合作项目探索基于微处理器和微传感器开发的具有成本效益的物联网（IoT）空气污染监测系统。选择监测的环境参数包括主要的cap、气象条件和现场的噪音，这些参数会实时传输到服务器。专业人员和决策者可以评估正在进行的场地状况对环境的影响，跟踪人类暴露于哪些污染物，并及时采取行动保护公众或工人免受伤害。拟议的系统将与Consul-Air公司一起在加拿大的实际工业现场进行测试和验证。研究结果还可进一步用于发展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. ******
