“…In our results, both reservoirs showed genetic potential for this harmful metabolism, especially in the river zone from Itupararanga, where this metabolism was overrepresented with 88% of the genes related to the antibiotic resistance and toxic compounds (Figure S2-2). For this reason, our results agree with previous studies which indicated that Itupararanga and Lobo have been receiving domestic effluents, probably from the rivers that inflow into the upstream (Rivera et al, 2007;Simonetti et al, 2019).…”

“…This eutrophication process is related to the runoff of fertilizers used in agricultural lands along the drainage basin. In addition, the release of inadequate wastewater treatment also contributes to the enrichment of nutrients in these ecosystems (Rivera et al 2007;Simonetti et al 2019).…”

“…Nota-se que as áreas de contribuição (ACs) possuem distinções físicas entre si, como a densidade de drenagem, quantidade de canais, declividade, precipitação e cobertura vegetal. Estas diferenças podem causar efeitos diversos à paisagem quando associadas ao uso e ocupação do solo como, por exemplo, áreas mais íngremes sobre um solo impermeabilizado aumentam o deflúvio, o qual por sua vez produz e transporta mais sedimentos, contribuindo com processos erosivos, assoreamento e poluição nos córregos, sendo estas informações importantíssimas para a tomada de decisão quanto a ocupação e uso do solo por gestores públicos (SILVA et al, 2016;SIMONETTI et al, 2019).…”

“…E-mails: (bruperton.cad@gmail.com, renan_angrizani@hotmail.com, roberto.lourenco@unesp.br, darllan.collins@unesp.br) Os recursos naturais e o sistema físico estão em constante modificação devido às atividades antrópicas e à evolução natural, e estas mudanças podem impactar de forma negativa na sociedade e no meio ambiente (TONELLO et al, 2006). Desta forma, a análise integrada de dados espaciais pode contribuir de forma significativa na identificação dos diferentes tipos de degradação resultante dessas modificações em uma bacia hidrográfica (SIMONETTI et al, 2019).…”

Frente às questões que envolvem gerenciamento e escassez de recursos hídricos, este trabalho tem como objetivo caracterizar a morfométrica da Bacia Hidrográfica do Rio Cotia (BHRC) – São Paulo (SP). Para tal fim, foram empregadas técnicas geotecnológicas e o modelo digital de elevação (MDE) Alos-Palsar para a determinação de parâmetros morfométricos e extração de drenagem, baseando-se em cinco áreas de contribuição. Os resultados apontaram que a bacia apresenta um formato alongado e com cursos d’água de até 6ª ordem. A BHRC apresenta alta densidade de drenagem, predominância de relevo com inclinação ondulada (8 a 20%) e redes de drenagem do tipo dendrítica. O Rio Cotia tem uma extensão de 35,7 km e a bacia tem uma área de 251,37 km² e um perímetro de 141,97 km. Os parâmetros de fator de forma (0,20), índice de circularidade (0,16), coeficiente de compacidade (2,51) e índice de sinuosidade (1,00) exibiram que a bacia tende a ter alto escoamento superficial e baixa probabilidade de enchentes. Portanto, os indicadores morfométricos podem ser usados em estudos comparativos entre bacias hidrográficas, além de identificar zonas mais adequadas para determinados usos de ocupação do solo, evitando-se impactos negativos e auxiliando, desta forma, na implementação de modelos de gestão ambiental.

“…Heavy metal contamination is the most important and widespread environmental issue all over the world. Among all the issues either natural or anthropogenic, entry of toxic elements from industrial wastewater is considered the major source for contamination in a natural reservoir of water (Simonetti et al, 2019). Naturally, the concentration of heavy metals varies by source.…”

G lobally, it has been recognized that water is one of the most important and critical natural resources to sustain life on this earth. Water composition is continuously changing due to natural and anthropogenic activities that ultimately cause environmental pollution (Yousaf et al., 2016). These pollutants include both chemical (Heavy metals, detergents, agrochemical residues, hydrocarbons etc.) and microbial (Bacteria, protozoa, virus, fungi etc.) pollutants from human and animal fecal waste which can be lethal to humans (Yi et al., 2011). Sedimentation of microorganisms into dissolved organic contents present in the wastewater through biological treatments considered the best approach to remove the microbial pollutants. It serves as that are substrates for the living organism present in the water Abstract | Industrial effluent discharge has increased due to rapid urbanization and industrialization. Irrational use of this water for irrigation has caused environmental and health issues. The objective of the current study is to evaluate the treated effluents of textile, ghee and chemical industries for major heavy metals (Cd, Cr, Ni, Pb and Fe) and other basic analysis (pH, EC, TSS and TDS). Effluent samples were collected from the discharge of industries entering into main wastewater collecting channel located in Faisalabad city. Heavy metals contents were determined via atomic absorption spectrophotometry. Results showed that the highest pH (11.06) was recorded in textile effluent while EC (7.89mS/cm), TSS (1185.55mg/L) and TDS (6317.33mg/L) were found highest in chemical industrial effluents. Heavy metals contents were determined through atomic absorption spectrophotometer. The mean comparison of heavy metal concentration (mg/L) showed the concentration of Cd, Cr and Ni were within the safe limits; however, Fe and Pb were higher than the safe limits in all industrial effluents. The highest/unsafe concentration of metal Fe was recorded 4.093, 2.979 and 2.959 mg/L in the effluents of chemical, textile and ghee mill respectively. While the highest/ unsafe concentration of metal Pb was recorded 0.643, 0.578 and 0.286 mg/L in the effluents of textile, chemical and ghee mill respectively. The permissible limits of heavy metals Fe and Pb is 0.5 and 2 mg/L respectively. We conclude that before discharge into a receiving stream, the effluents must be treated more time with a treatment method that removes Pb and Fe within standard limits else the discharge will pose pollution and health risks to human beings.
