This article presents a synthesis of information about the massive oil spill in Brazil (2019/2020). The event afected 11 states; however, the majority of the oil residue was collected (~ 5380 tons) near nine states (99.8%) in northeastern Brazil. This spill was not the largest in volume (between 5000 m3 and 12,000 m3 ) recorded in tropical oceans, but it was the most extensive (2890 km). This spill develops an ...
In early September 2019, dense crude oil began to wash the beaches of Brazil's tropical coast. Four months after the first report, the oil has already been found along >3000 km of the Brazilian coastline on >980 beaches and was recently observed along the Amazon coast, making this oil spill the most extensive and severe environmental disaster ever recorded in Brazilian history, in the South Atlantic basin, and ...
This work pretends to evaluate atmospheric emissions from the processes related to asphalt paving works (production, transportation and placement of asphalt mixtures). Asphalt paving services promote the development of large urban centers, as they facilitate the transportation of goods and population. However, they bring various environmental products, especially air pollution. For the accomplishment of these o...
Nos centros urbanos, as principais fontes poluidoras antropogênicas são oriundas do tráfego de veículos e, quando existente, da atividade industrial. Tal problemática faz da poluição atmosférica urbana um dos principais fatores de degradação da qualidade de vida da população. Entre as variáveis que influenciam no transporte e difusão dos poluentes podemos citar as condições meteorológicas, onde a ocorrência de ...
A cidade de Fortaleza passa por um processo de verticalização, especialmente em áreas de alto padrão econômico. Investigações sobre o impacto de determinado aspecto do desenho urbano nas condições microclimáticas no entorno de edificações crescem a cada dia, fazendo-se necessário a verificação de forma mais detalhada dos diferentes espaços intraurbanos para que seja possível identificar as causas das diferenças...
The city of Fortaleza undergoes a process of verticalization, especially in areas of high economic standard. Investigations on the impact of a certain aspect of urban design on microclimatic conditions in the surroundings of buildings are growing every day, making it necessary to verify in a more detailed way the different intra-urban spaces so that it is possible to identify the causes of the differences of th...
Services in asphalt pavement are commonly employed in large urban centers. Recently, the International Agencyfor Research on Cancer (IARC) classified the external atmos-pheric particles as Group 1, i.e., proved to be carcinogenic to humans. In this way, the main objective of this study was to evaluate the levels of Respirable Particulate Mate-rial (RPM) in the asphalt fumes, as well as the health risk at the mo...

O experimento didático objetiva mostrar a importância da validação do método analítico no estudo da química do sulfato no meio ambiente. Apesar do método de determinação de sulfato apresentar linearidade satisfatória, sensibilidade, limite de detecção e quantificam precisão em matrizes aquosas, este experimento mostrou que ele tem baixa exatidão para matrizes aquosas complexas, como água de lagoa e de estuário....
