O Brasil possui um grande volume de mananciais superficiais ao longo sua extensão. Para além da quantidade corpos hídricos, tem como característica marcante altas temperaturas do ano. Somado a esses fatores, existe uma ineficiência no saneamento básico, sobretudo em relação à coleta esgotos, favorecendo o despejo desses nos mananciais, aumentando oferta nutrientes e consequentemente proliferação escala cianobactérias. Dessa forma, presente trabalho teve objetivo analisar ocorrência...
Bearing in mind that universal access to sanitation services is one of the objectives Brazilian Plan for Basic Sanitation and sustainable development goals (SDG), this research sought evaluate coverage supply quality water distributed Brazil 2019. Data from National Information System (SNIS) Water Quality Human Consumption Surveillance (Sisagua) databases were evaluated. It was found 82% population has Supply Systems (WSS), percentage only being lower North (58%) Northeast (74%) regions....
Water is essential for the socio-economic development of a region and also survival human beings. scarcity has direct indirect impacts on environment, economy health. It can change profile morbidity mortality diseases, as well having an impact supply services that are public to quality life. This study aims contextualize occurrence drought in Brazil, its effects health, actions be developed by health sector reduce risk those living affected areas, with emphasis monitoring drinking water....
Abstract Low quality drinking water has been directly correlated to the occurrence of waterborne illnesses in northern Brazil. To minimize health risks related supply, Ministry Health proposed implementation National Program for Surveillance Drinking Water Quality (VIGIAGUA) Brazilian municipalities. Focusing on Legal Amazon region, present study demonstrates a historical account percentage municipalities included VIGIAGUA program place, which 2013 reached 45.1% region This also identifies...
Apresentam-se, neste trabalho, os resultados (i) da caracterização água de lavagem filtros (ALF) estação tratamento Universidade Federal Viçosa (ETA- UFV); (ii) ensaios clarificação ALF em colunas sedimentação, com e sem uso polímeros; (iii) recirculação ETA piloto (EP), sob condições variadas razão (5 a 20% incremento vazão) turbidez mistura bruta (AB) (12,1 257,3 uT). Na foram encontradas concentrações ordem grandeza 10¹ cistos Giardia spp. oocistos Cryptosporidium por litro. Os dos coluna...
This paper presents the results of five years monitoring an experimental wastewater treatment plant in southeast Brazil, comprised a UASB reactor followed by submerged aerated biofilter (BF) (field scale) and shallow polishing ponds (pilot scale). Three series achieved high quality effluent standards terms ammonia E.coli, but fourth pond did not result further efficiency. Well established models to predict E.coli removal facultative and/or maturation were, way, validated for too. The also...
RESUMO A região hidrográfica da Bacia Baía de Guanabara integra 17 municípios do estado Rio Janeiro, entre os quais estão maiores geradores resíduos sólidos: São Gonçalo, Belford Roxo, Nova Iguaçu, Janeiro e Duque Caxias. O lixiviado, efluente altamente tóxico, quando descartado maneira inadequada, pode provocar diversos impactos negativos nos corpos hídricos. Este trabalho apresenta, por meio uma abordagem qualitativa quantitativa, as áreas destinação final sólidos principais hídricos...
Abstract Cryptosporidium, faecal indicator organisms and physical chemical water quality variables were monitored in a small mixed rural–urban watershed southeastern Brazil. Cryptosporidium was present 43% of 117 samples analysed by microscopy. Concentrations varied from non-detects to 14 oocysts L−1. All further nested-PCR, spp. detected 24% (28) them. Sequencing at the 18S rRNA locus gave high sequences eight samples, revealing presence parvum. not correlated with (total coliforms,...
Abstract A growing amount of data in the scientific literature indicates that emerging contaminants, such as Endocrine Disruptors Chemicals (EDCs), have increased concentration water bodies recent years. The main objective this research was to compile on legal and regulatory frameworks different locations regarding control estrogens (an EDC) surface drinking waters, support regulation countries where it has not shown significant advances. An analysis carried out provisions aimed at...
Several Brazilian regions have been facing consecutive water crises and one advantageous alternative considered, in environmental economic terms to guarantee demand, is the reuse, especially gray water, yet Brazil lacks specific legislation that their reuse.The aim of this work was analyze legal institutional instruments regarding reuse for non-drinking purposes, as well level restriction these legislations.Twelve documents were selected, from which only five established quality parameters...
O aproveitamento das águas da chuva tem se tornado um tema fundamental, no sentido de garantir a sustentabilidade dos recursos hídricos e melhoria condições sanitárias em determinadas localidades. Este trabalho visa avaliar influência revestimentos telhados metálicos fibrocimento na qualidade pluviais obtidas sistemas captação armazenamento água pluvial, Rio Janeiro. Foram coletadas analisadas 57 amostras volumes armazenados nos pontos first-flush (FF) reservatório (RR), entre 2017 2019,...
Com o crescimento acelerado da população brasileira nos centros urbanos, gerenciamento de resíduos vem sendo um dos principais desafios devido ao volume diário produzido e a complexidade encontrar soluções para tratamento destinação desses. Os potenciais impactos associados aos sólidos urbanos motivam desenvolvimento pesquisas científicas sobre assunto Avaliação do Ciclo Vida (ACV) destaca-se como uma técnica apoio à tomada decisão modelo resíduos. No entanto, confiabilidade resultados é...
