Tocantins State faces a large-scale agricultural expansion. Thus, climate studies are essential for better understanding of variability supporting and environmental planning. In this context, study applies the climatic classification Thornthwaite develops regionalization through geostatistical techniques, assessing performance interpolators ordinary kriging (OK) cokriging (CK). Data from 26 weather stations located in surroundings were used. The variables interest to regionalization,...
The broad expanse of the urban metropolitan area São Paulo (MASP) has made buses, predominant public transport mode for commuters in city. In 2016, bus fleet MASP reached 56,354 buses and it was responsible more than 12 million daily trips. Here, we evaluate first time, emission profile gaseous particulate pollutants from running on 7% biodiesel + 93% petroleum diesel their spatial distribution MASP. This novel study, based four terminal experiments, provides an extensive analysis...
Analyzing historical droughts is essential to improve the assessment of future hydrological risks and understand effects climate variability on streamflow. However, prolonged consistent time series are scarce in Brazilian savanna region. This study aimed analyze performance reanalysis products precipitation estimation, modeling, drought analysis a basin. For this purpose, data from twentieth-century atmospheric model ensemble (ERA-20CM) land component fifth generation European ReAnalysis...
RESUMO A epidemiologia baseada em esgotos é uma importante ferramenta de saúde pública com grande aplicabilidade no enfrentamento à pandemia COVID-19, visto que indivíduos infectados são capazes excretar partículas SARS-CoV-2. Diante desse contexto, este estudo objetivou correlacionar o número casos COVID-19 variáveis físicas e químicas presença do vírus amostras esgoto bruto provenientes estação tratamento (ETE) município Lavras (MG) coletadas entre as 19ª 25ª semanas epidemiológicas. As...
Técnicas de remoção nutrientes têm sido empregadas no tratamento efluentes com a inclusão uma etapa biológica. Sendo os microrganismos nitrificantes responsáveis pelas transformações das formas nitrogenadas, o objetivo deste estudo foi detectar e quantificar bactérias provenientes do um canil. Foi realizada caracterização efluente obtida correlação entre as variáveis medidas. Avaliou-se densidade partir biofilme coletado filtro biológico aerado submerso, fez-se cultivo, isolamento observação...
Dentre as componentes necessárias à realização do balanço hídrico climatológico, encontra-se a evapotranspiração de referência. Esta, refere-se às saídas água solo e tradicionalmente é calculada por diferentes métodos indiretos, partir observações realizadas nas estações meteorológicas. Neste trabalho, informações 27 meteorológicas convencionais localizadas no estado Minas Gerais foram avaliadas, objetivando-se identificação tendências climatológicas ao estudo das anomalias período...
We investigated the influence of natural and anthropogenic sources on bulk atmospheric deposition chemistry, from November 2017 until October 2019, in a Brazilian agricultural area. The pH mean value was 5.99 (5.52–8.46) most samples (~98%) were alkaline (pH > 5.60). identified Ca2+ as predominant species, accounting for 33% total ionic species distribution main precursor acidity neutralization (Neutralization Factor = 6.63). PMF analysis resulted four factors, which demonstrated sources,...
Abstract Since January 2020, some studies have been reporting a reduction in air pollution several countries due to social isolation measures, which adopted order contain the coronavirus outbreak progress (Covid-19). This study aims evaluate change atmospheric levels by NO and 2 São Paulo city period. The hourly concentrations were obtained through quality monitoring stations from CETESB, 14 April 12, 2020. Mann-Kendall Pettitt tests performed pollutants time series. We observed an overall...
Abstract Understanding the seasonal patterns and influencing factors of nitrogen atmospheric deposition is essential to evaluate human impacts on air quality biogeochemical cycle. However, evaluation flux, especially in South America agricultural regions, has not been fully investigated. In this paper, we quantified wet fluxes total dissolved (TDN), organic (DON) inorganic (DIN), a region with livestock predominance Southern Minas Gerais region, Brazil, from May 2018 April 2019. Deposition...
