“…O que acontece com a bacia de Educandos na cidade de Manaus é semelhante ao ocorrido na cidade de São Paulo. Nesta cidade, a expansão urbana, o rápido desenvolvimento econômico e o aumento considerável da população, não foi acompanhado por uma ampliação dos serviços de tratamento de esgoto e de toda a infraestrutura de saneamento capaz de manter a saúde de seus corpos d'agua (Rocha et al, 2022b). Dessa forma, a baixa qualidade das águas da bacia é resultado de algumas décadas de degradação pelo carregamento elevado dos diferentes resíduos poluentes, produzidos na parte urbana da cidade, que chega até seu leito.…”

The city of Manaus has undergone an industrialization process that has negatively influenced the wastewater that makes up the urban part of the city. Monitoring water quality parameters and seasonal changes are essential for decision-making for the recovery of the basin's waters. The study evaluated, through the Water Quality Index (WQI) and multivariate statistical techniques, the seasonal and spatial variation in water quality in the Educandos basin, Manaus. The 14 sampling points were selected in the years 2020, 2021 and 2022. The analyzes followed the recommendations of the Stantard Methods for the Examination of Water and Wastewater. The IQA showed that seasonality has not been enough to cause an improvement in water quality. Cluster analysis ranked similar sample points in relation to water quality. The main component showed that turbidity, total solids and biological oxygen demand are the most relevant parameters for PC1, while for PC2 they were Total Coliforms, Total Nitrogen and pH. The multivariate analysis proved to be efficient for monitoring the basin, considering the process of environmental deterioration, resulting from the receipt of waste of mixed domestic and industrial origin.

“…Te streams described by researchers focus on comprehending high absorption of micronutrients [25], and identifying pollution sources of minute constituents as well as their quantities is still very challenging [26]. Most studies on stream contamination concentrate on common heavy metals, omitting data on the longitudinal distribution of minor nutrients and the order of the urban environment [27]. Despite extensive ecological degradation in many African countries, identifying pollution sources remains a major challenge [28].…”

Lack of nutritive and consumption of polluted food sources are the main health implications in African countries. Vegetable production is an optional balanced food source easily grown in the urban and rural areas. However, the levels of contaminant heavy metals in cultivated vegetables have not yet been identified. This review scrutinizes the contamination route, sources, health effects, environmental problems, food safety complications, and remedial activities of vegetable production in Ethiopian agriculture. Informal settlement, the rapid rate of urbanization, and the lack of community-based industrial expansion lead to massive increases in toxic heavy metals in ecosystems. They are supplied with food source diets unrestrictedly, mainly for vegetable consumption. Among the assessed metals, Zn (112.7 mg/kg), Cr (47.7 mg/kg), Pb (17.76 mg/kg), and Cd (0.25 mg/kg) existed in vegetables, with the highest concentrations in Ethiopia. They have negative effects on public safety, environmental security, and nutrient levels in horticultural crops. Hence, Ethiopia has no permissible standards for vegetable consumption and hazard analysis, critical control point, or food safety system. Additionally, physical, biological, and natural remedial strategies such as phytoremediation, phytoextraction, phytostabilization, rhizofiltration, bioremediation, and phytovolatilization are not applied to curtail deadly substance contents in Ethiopia. Despite this, some mitigation strategies, such as industrial waste treatment activities, are underway in Ethiopia’s universities and beer and sugar factories. This review found that the use of integrated remedial strategies could help to improve the efficiency of strategies in a sustainable manner, solid safety control for heavy metal management in Ethiopia, and management should begin with local solutions.

“…No Brasil são poucas as bacias que recebem algum tipo de monitoramento da qualidade de suas águas, os poucos trabalhos realizados demonstram altos níveis de contaminação, como a presença de coliformes fecais, o que expressa a necessidade de saneamento nessas bacias (Blume et al, 2010;Rocha et al, 2022),…”

A construção de um empreendimento de infraestrutura depende desde fatores socioeconômicos até climáticos na região da obra. O estado de Rondônia é reconhecido por apresentar chuvas abundantes no contexto amazônico ao qual está inserido. Esta pesquisa propõe determinar o Fator de Influência das Chuvas (FIC) no contexto de obras de infraestrutura em Rondônia. Para tanto será utilizada a Metodologia DNIT (2017), a qual estima esse fator a partir de dados relacionados à atividade, permeabilidade do solo, escoamento superficial e percentual médio de dias efetivamente paralisados em função das chuvas. Para obtenção dos dados pluviométricos, consideraram-se as séries históricas de seis estações pluviométricas no período compreendido entre 1999 e 2017. Atualmente, o FIC rondoniense considera somente três estações pluviométricas, tornando-se este estudo uma proposta de expansão para uso de mais dados na forma de estudo de caso. O FIC pode servir para projetos, planejamento do cronograma da execução dos serviços e no incremento orçamentário de obras de infraestrutura terrestres e aquaviárias. Esta pesquisa se alinha ao objetivo de desenvolvimento sustentável número nove da Agenda 2030 que discorre sobre ações e estudos voltados à indústria, a inovação e a infraestrutura.
