A conservação e preservação do meio ambiente devem levar em conta a percepção e o comportamento dos indivíduos em relação às questões ambientais. Nessa perspectiva, o objetivo deste trabalho foi analisar a percepção dos moradores no bairro Tijuca, Rio de Janeiro, sobre a gestão de resíduos sólidos e seu nível de conscientização ambiental, com enfoque […]
On March 11, 2020, the World Health Organization declared that the epidemic of the new Coronavirus disease (COVID-19) was out of control and had become a global zoonotic pandemic. Consequently, more than 190 countries have implemented measures to contain the outbreak of the disease, including the Lockdown, mainly to avoid the saturation of their health […]
This global study, which has been coordinated by the World Meteorological Organization Global Atmospheric Watch (WMO/GAW) programme, aims to understand the behaviour of key air pollutant species during the COVID-19 pandemic period of exceptionally low emissions across the globe. We investigated the effects of the differences in both emissions and regional and local meteorology in […]
O principal objetivo desse trabalho foi avaliar as concentrações de poluentes em duas estações de monitoramento contínuo de poluentes localizadas na Baixada Fluminense, estado do Rio de Janeiro, Brasil, durante o período de greve dos caminhoneiros, entre os dias 21 e 30 de maio de 2018. As duas estações – Jardim Primavera e Jardim Guandu […]
The Metropolitan Region of Rio de Janeiro is the second largest urban and industrial region in Brazil. While the south and south-east areas are affected by vehicular emissions, the districts and cities located in the northern area are subjected to industrial emissions and have the poorest air quality of the region. In this study, BTEX […]
Air quality management is a serious challenge, especially in middle-income countries, where resources are limited and there are widely varying geographical, meteorological and economic conditions. In this study, air quality data obtained in the period January–April, from 2012 to 2019, were compared with the results obtained in 2020, to assess the impact of urban mobility […]
There have been several works on criteria emissions from biofuels and their mixtures. In this study, the focus is on emissions of non-criteria pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and their nitrated (nitro-PAHs) and alkylated analogs (alkyl-PAHs). The determinations were made using a standard engine from the fleet of vans used in Brazilian towns […]
Gas chromatography (GC) determination of C2-C12 hydrocarbons (HCs) in atmospheric samples is a complex task. In general, it involves employing two chromatographic systems or a double gas chromatograph, where the gaseous sample is divided into two fractions. In this study an alternative system is put forward for the analysis of ambient air samples, including urban, […]
As recently acknowledged by the World Health Organization (WHO), there is strong evidence that air pollution affects human health at even lower concentrations that previously understood. Exposure to fine particulate matter is related to ischemic heart disease and stroke, to chronic pulmonary disease and has impact on child health and survival. The most recent Brazilian […]
A questão das Mudanças Climáticas é um dos maiores problemas ambientais atuais. Estudos indicam que a solução para esta problemática depende de participação popular, mas apesar de tal abordagem ser prevista pela Educação Ambiental, a deficiência de recursos didáticos dificulta a execução desta prática. Este estudo objetivou, portanto, identificar e compreender diferentes elementos de mídia […]
