“…The pressures on air quality are assessed through the use of emission inventories [44] and through experimental measurements conducted in the laboratory or in real contexts [45]. In considering the direct relationship between polluting emissions and the presence of vehicular traffic, the significant reduction in the number of vehicles circulating during the lockdown period has favoured a consequent reduction in polluting concentrations in the atmosphere and the quality of movement [29,46,47], although with further related problems (increase in speeds, more frequent harsh acceleration and harsh braking events) [48].…”

The Impact of the COVID-19 Emergency on Local Vehicular Traffic and Its Consequences for the Environment: The Case of the City of Reggio Emilia (Italy)

The COVID-19 health emergency has imposed the need to limit and/or stop non-essential economic and commercial activities and movement of people. The objective of this work is to report an assessment of the change in vehicle flows and in air quality of a specific study area in the north of Italy, comparing the periods February–May 2020 and February–May 2019. Circulating vehicles have been measured at nine characteristic points of the local road network of the city of Reggio Emilia (Italy), while atmospheric pollutant concentrations have been analysed using data extracted from the regional air quality monitoring network. The results highlight a rapid decline in the number of vehicles circulating in 2020 (with values of up to −82%). This has contributed to a reduction in air concentrations of pollutants, in particular for NO2 and CO (over 30% and over 22%, respectively). On the other hand, O3 has increased (by about +13%), but this is expected. Finally, the particulate matter grew (about 30%), with a behaviour similar to the whole regional territory. The empirical findings of this study provide some indications and useful information to assist in understanding the effects of traffic blocking in urban areas on air quality.

“…-Industrial processes and product use: NMVOC (44%) and PM2.5 (12%) -Energy use in industry: SOx (20%) and NOx (12%) -Road transport: NOx (36%) and PM2.5 (11%) -Non road transport: NOx (9%) Overall, this condition has generated a strong impact on environmental quality, with positive effects on numerous environmental matrices such as soil and water [32,33], but also negative, for example on waste management [34,35]. Since there is a direct relationship between human activities and emissions of air pollutants, this blocking condition has favoured a significant improvement in environmental quality [36][37][38][39][40][41][42][43][44].

The health emergency linked to the spread of COVID-19 has led to important reduction in industrial and logistics activities, as well as to a drastic changes in citizens' behaviours and habits. The restrictions on working activities, journeys and relationships imposed by the lockdown have had important consequences, including for environmental quality. This review aims to provide a structured and critical evaluation of the recent scientific bibliography that analysed and described the impact of lockdown on human activities and on air quality. The results indicate an important effect of the lockdown during the first few months of 2020 on air pollution levels, compared to previous periods. The concentrations of particulate matter, nitrogen dioxide, sulphur dioxide and carbon monoxide have decreased. Tropospheric ozone, on the other hand, has significantly increased. These results are important indicators that can become decision drivers for future policies and strategies in industrial and logistics activities (including the mobility sector) aimed at their environmental sustainability. The scenario imposed by COVID-19 has supported the understanding of the link between the reduction of polluting emissions and the state of air quality and will be able to support strategic choices for the future sustainable growth of the industrial and logistics sector.This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process which may lead to differences between this version and the Version of Record.

“…A frota veicular em centros urbanos aumentou exponencialmente nos últimos anos, e isso é um dos principais motivos para o aumento da poluição atmosférica nessas regiões; assim, torna-se cada vez mais importante a busca de soluções para mitigar essas consequências (Mitra et al, 2002;Campos et al, 2010;Righi et al, 2013;Azevedo, 2014;CETESB, 2014;COP21, 2015;Papamanolis, 2015).…”

Resumo O crescimento urbano desorganizado tem gerado muitos problemas em grandes centros urbanos, sobretudo reduzindo o conforto ambiental da população local. A administração pública está cada vez mais procurando mitigar esses efeitos, melhorando a qualidade de vida da população por meio de um modelo de gestão mais sustentável, com ações de implantação de Ambientes Urbanos Desportivos (AUDs). A cidade de Fortaleza, no Ceará, é a quinta maior capital da federação em termos de quantidade populacional. Além disso, possui uma frota de mais de 1 milhão de veículos em circulação. Os AUDs foram instalados em muitos bairros da cidade com o objetivo de oferecer áreas de lazer e recreação para a população local. Contudo, a qualidade do ar nessas áreas ainda é desconhecida por causa da ausência de ações de monitoramento, especialmente durante uma intensa prática de atividade física. Este trabalho tem como objetivo monitorar espécies atmosféricas, NO2, NH3, SO2 e H2S, em 13 AUDs (diferentes bairros da cidade de Fortaleza) utilizando sistemas portáteis. Os resultados mostraram que as concentrações de gases detectados nos dias monitorados foram (em μg.m-3): de 2,58 a 18,48 de NO2; de 0,18 a 3,36 de SO2; de 2,78 a 11,07 de NH3; e de 0,76 a 7,53 de H2S. Reduções significativas das concentrações de NO2 (41%) e NH3 (~ 60%) foram observadas nos finais de semana, como resultado da diminuição do tráfego veicular. Além disso, o monitoramento da qualidade do ar nos AUDs pode sugerir e/ou apoiar políticas públicas para controlar a poluição do ar na cidade de Fortaleza.
