However, the ability of a drone to automatically detect when the concentration of a pollutant has exceeded the recommended threshold has not been reported.…”

“…Drones have been investigated as a means to detect environmental air pollution (Altstadter et al, 2015;Brady et al, 2016;Chang et al, 2018;Chilinski et al, 2018;Corrigan et al, 2008;Lawrence and Balsley, 2013;Mayer et al, 2012;Ramana et al, 2007;Ramanathan 2006;Reuder et al, 2012;Smidi and Hofman, 2013;www.scmp.com;techrepublic.com;www.auav.com.au;www.nationaldrones.com.au;Villa et al, 2016;Vo et al, 2018;Watai et al, 2006). CO 2 , CH 4 , Particulate Matter (PM), NO 2 , volatile organic compounds (VOCs), ozone, and water vapor concentrations have been successfully measured (Alvear et al, 2017;Babaan et al, 2018;Berman et al, 2012;Fladeland et al, 2011;Gu et al, 2018;Illingworth et al, 2014;Ruiz-Jimenez et al, 2019).…”

“…A concentração média de ozônio para as coletas entre 9 da manhã e 5 da tarde foi de 79,2 µg/m 3 , com valores mínimos de 55,2 µg/m 3 e máximo de 122,8 µg/m 3 . O perfil diurno de ozônio mostrou altos valores de concentração do meio dia para o fim da tarde, horário com maior incidência de radiação solar, concordando com o que tipicamente se espera pelas reações fotoquímicas combinadas com os perfis de emissão diurna em áreas urbanas (TOHID et al, 2019;VO et al, 2018 As concentrações SO2 e NO2 apresentaram-se consideravelmente abaixo dos valores de referência apresentados pela resolução CONAMA 491/2018, utilizada para comparação. Os períodos de maior radiação solar ultravioleta contribuem fortemente para a elevação das concentrações de ozônio, contudo os padrões nacionais não foram ultrapassados e apenas duas coletas ultrapassaram legislações internacionais.…”

RESUMO A queima de combustíveis fósseis e as atividades industriais são os principais responsáveis pela emissão de poluentes atmosféricos. Esses poluentes estão cada vez mais associados a efeitos negativos à saúde humana. Este trabalho teve como objetivo avaliar a qualidade do ar no município de São Gonçalo do Amarante, Estado do Ceará, o qual possui 46,8% de seu território na área do Complexo Industrial do Pecém (CIP). Experimentalmente, foram realizadas coletas no período entre outubro e dezembro de 2015 para os parâmetros de: material particulado total em suspensão (PTS), NO2, SO2, O3 e metais pesados (Fe, Ni, Cu e Pb) usando amostradores de grande volume (64 m 3 /h) para o PTS e de pequeno volume (0,20 L/min) para o SO2 e NO2. O O3 foi determinado por absorção no ultravioleta (254 nm) e as concentrações dos metais pesados associados ao PTS foram estimadas por espectroscopia de absorção atômica. Os resultados mostraram níveis de PTS (24 h) entre 32,6 e 75,3 µg/m 3 e de ozônio (1 h) entre 63,8 e 165,6 µg/m 3. As concentrações de SO2 e NO2, por sua vez, apresentaram-se muito abaixo dos valores estabelecidos pela resolução CONAMA 491/2018. Entre os metais somente o ferro foi quantitativamente identificado, com níveis entre 3,6 e 19,9 µg/m 3. Em geral, os valores obtidos mostraram que a qualidade do ar na área durante o período do estudo pode ser considerada boa para os poluentes ambientais analisados.

“…In addition to the adverse health effect on the respiratory system and carcinogenesis risks [4,5,6,7,8], VOC emission contributed to regional air pollution [9,10]. VOCs were also major precursors of ozone (O 3 ) and secondary organic aerosols (SOA) [11,12,13]. Taking toluene as an example, smog chamber studies showed SOA production and yields were much higher under urban ambient air against that with purified air when toluene coexisted with NO x and SO 2 [14].…”

Volatile organic compounds (VOCs) emission from anthropogenic sources has becoming increasingly serious in recent decades owing to the substantial contribution to haze formation and adverse health impact. To tackle this issue, various physical and chemical techniques are applied to eliminate VOC emissions so as to reduce atmospheric pollution. Among these methods, non-thermal plasma (NTP) is receiving increasing attention for the higher removal efficiency, non-selectivity, and moderate operation, whereas the unwanted producing of NO2 and O3 remains important drawback. In this study, a dielectric barrier discharge (DBD) reactor with wedged high voltage electrode coupled CuO foam in an in plasma catalytic (IPC) system was developed to remove toluene as the target VOC. The monolith CuO foam exhibits advantages of easy installation and controllable of IPC length. The influencing factors of IPC reaction were studied. Results showed stronger and more stable plasma discharge in the presence of CuO foam in DBD reactor. Enhanced performance was observed in IPC reaction for both of toluene conversion rate and CO2 selectivity compared to the sole NTP process at the same input energy. The longer the contributed IPC length, the higher the toluene removal efficiency. The toluene degradation mechanism under IPC condition was speculated. The producing of NO2 and O3 under IPC process were effectively removed using Na2SO3 bubble absorption.
