Guildford Living Lab (GLL) and Zero Carbon Guildford (ZCG) initiated a collaborative air quality study to synergistically employ low-cost sensors within a public building. The aims were to develop a real-time Live Air Pollution Data (LAPD) tool for the public and raise awareness and citizen engagement through interactive quiz system. Whilst doing so, we monitored indoor and outdoor (I/O) concentrations of particulate matter (PM) and carbon dioxide (CO₂) and assessed horizontal and vertical variation of CO₂. We found that short indoor public events can raise CO₂ up to 1000 ppm; people's movements during these events can elevate PM₁₀ concentration. The PM₁₀ and CO₂ concentrations increased with the number of occupants and their distribution inside the ZCG building. Dust resuspension due to occupant activities was the main driver for high PM₁₀ concentrations, while the smaller particles (PM_2.5 and PM₁) were linked to the ingress from outside. In addition, the change in the number of occupants showed no effect on PM_2.5 and PM₁ concentrations. We found significant stratification in CO₂ in the vertical direction, accumulating CO₂ close to the ceiling inside the building. Concurrently, CO₂ in the horizontal direction was uniform without any significant variation. The analysis of data from the Interactive Quiz System revealed that 16 % of the participants had the highest air pollution exposure in their day-to-day activities. The collaborative development of LAPD and the live presentation of air pollution data to the public effectively disseminated air quality information, leading to improved awareness among individuals. This work demonstrated the citizen science approach's effectiveness in understanding and mitigating air pollution issues through a collaborative, inclusive, knowledge-sharing environment. This study inspires further citizen science initiatives between scientists, the public, research funding institutes, authorities and agencies.</p></div>","PeriodicalId":101199,"journal":{"name":"Sustainable Horizons","volume":"10 ","pages":"Article 100086"},"PeriodicalIF":0.0,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772737823000408/pdfft?md5=f267e043240a87d25aec92e5c26eab24&pid=1-s2.0-S2772737823000408-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139434578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the application of these products resulted in an increase in soil pH value, urease activity, and bacterial Shannon index, thereby enhancing soil properties. The immobilization effects were more significant in Pb-contaminated soil compared to Cd-contaminated soil, and MAP and KMP exhibited a stronger passivation effect on Pb in comparison to HAP. For soil fertility improvement, a molar ratio of 10:1 was recommended, whereas a ratio of 5:1 effectively passivated Pb in contaminated soil.

However, urban air quality managers are having great difficulty achieving targeted pollution control goals in the time allotted due to limited studies in the region. In this study, using the city of Siping in Jilin Province as a case study, we analysed the cause of seasonal atmospheric pollution, developed a high-resolution emissions inventory for major atmospheric pollutants and simulated urban air quality improvements under projected emission control scenarios to select a reasonable source control scheme to inform urban air quality management planning in the region. Years with available air quality data (2014–2020) were divided into three periods, i.e., a weak control period (WCP: 2014–2017), an enhanced control period (ECP: 2018–2019) and the COVID-19 period (CDP: 2020). The annual PM_2.5, PM₁₀, SO₂ and NOx emissions varied by 62∼46 μg·m⁻³, 103∼76 μg·m⁻³, 27∼22 μg·m⁻³ and 46∼41 μg·m⁻³, respectively, during the WCP; the emissions decreased to 37 μg·m⁻³, 69 μg·m⁻³, 11 μg·m⁻³ and 34 μg·m⁻³, respectively, during the ECP and to 33 μg·m⁻³, 61 μg·m⁻³, 11 μg·m⁻³ and 33 μg·m⁻³, respectively, during the CDP, which reached the limits of the Ambient Air Quality Standard of China (level II, 35 μg·m⁻³, 70 μg·m⁻³, 60 μg·m⁻³ and 50 μg·m⁻³). The PM_2.5 and PM₁₀ indices exceeded the standards, mainly in late autumn (October and November) and in the middle of winter (January and February). Based on comprehensive data analysis of the spatiotemporal air quality and the local high-resolution emissions inventory, straw burning, stationary combustion (especially for coal burning) and vehicle emissions were the main pollution sources in late autumn, and continuous adverse weather conditions were the dominant factors in severe pollution days during the middle of winter. In addition, the urban air quality of Siping was also affected by pollutant transport from the northwest (the city of Songyuan in Jilin Province), northeast (the city of Changchun in Jilin Province) and south (the city of Tieling in Liaoning Province) according the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model. Strict straw-burning policy was implemented in autumn during the ECP and CDP, which significantly improved the air quality from that of the WCP, with an AQI reduction of 31.58 %.
