“…55 Other studies carried out in Brazil have found concentrations similar to those of the present work. 56,57 Other triazines were also investigated in this work, with emphasis to ametryn, which presented a maximum concentration of 148 ng L -1 in the investigated samples. The herbicides clomazone and bromacil were also quantified at similar concentrations, but the latter was detected only in 2% of the samples.…”

Emerging contaminants have been considered one of the main concerns for ensuring the quality of water around the world. This work presents the results of 10 years of analyses carried out in the state of São Paulo (Brazil) that has the high population density and intense agricultural and industrial activities. In this work 58 compounds (9 hormones, 14 pharmaceuticals and personal care products, 8 industrial compounds, 17 pesticides and 10 illicit drugs) were determined from 2006 to 2015 in 708 samples including raw and treated sewage, surface and ground and drinking waters. A preliminary risk assessment for aquatic life protection identified potential risks for caffeine, paracetamol, diclofenac, 17α-ethynylestradiol, 17β-estradiol, estriol, estrone, testosterone, triclosan, 4-n-nonylphenol, bisphenol A, atrazine, azoxystrobin, carbendazim, fipronil, imidacloprid, malathion and tebuconazole. Drinking water criteria were available only for 22 compounds and for them no adverse effects were expected at the concentrations found, except for 17β-estradiol.

“…Knowing that the location, preservation state of riparian forest, as well as the economic activities developed in each river basin are decisive for surface water pollution control. The monitoring of metals and pesticides in rivers surrounded by intensive industrial and agricultural activities is very important (Machado et al, 2016). Still, it is expressive the concern of Brazilian research with tannery (Rocha & Oliveira, 2017), copper (Simonato et al, 2016), heavy metals (Paula Filho et al, 2015) and microplastics (Santana et al, 2016).…”

The goal of this paper is to analyze the knowledge development on biomonitoring using comet assay on fishes. Were selected 154 papers in the ISI Web of Science and PubMed databases. The comet assay was used by 24.7% of the papers with the purpose to evaluate genotoxicity of polluted water. Comet assay is many times associated with other techniques, offering good results to increase efficiency in environmental assessment or to evaluate genotoxicity of pollutants individually.

Mesmo os elementos essenciais (Cu, Fe, Zn e Ni), com importante função nos sistemas biológicos, têm um significado particular em ecotoxicologia devido ao seu potencial de bioacumulação e consequentemente de toxicidade (Weber et al, 2013;Machado et al, 2016;Viana et al, 2018). Assim, quantidades elevadas de metais no ambiente aquático, tanto elementos essenciais e não essenciais, podem causar sérios riscos para a biota aquática, devido ao seu potencial de bioacumulação.…”

The aim of the study was to evaluate quantitative physical-chemical parameters of water from streams in the Tarumã microbasin (MS, Brazil), to quantify metals (Cd, Pb, Cr, Cu, Fe, Zn and Ni) in the bottom sediments of these streams and to evaluate quali-quantitatively the vegetation index of normalized difference of locations (NDVI) by means of satellite images.Water turbidity and electrical conductivity values were highest at the nearest points in the urban region. In the NDVI analysis, sites P1, P2 and P4 presented reduced local ciliary vegetation, classified as low or very low. At sites P3, P5 and P6 we found higher proportions of vegetation at moderate and low levels. Regarding metals in sediments, all sampled sites presented metal concentrations below the limits established by current legislation. The low rate of vegetation cover around streams in the Tarumã microbasin, especially in spring sites, may compromise the equilibrium of this system.
