Diagnóstico Socioambiental Da Comunidade Do Crespo, Manaus/Amazonas

Abstract

Este trabalho tem por objetivo apresentar um diagnóstico socioambiental da comunidade do Crespo utilizando-se dos dados de saneamento (distribuição de água, drenagem de esgoto e limpeza urbana). O bairro do Crespo situa-se na zona Sul da cidade de Manaus (AM) na microbacia do Igarapé do Quarenta. Para a obtenção dos dados, utilizou-se o método de pesquisa participativa por meio da aplicação de questionários mediante anuência da comunidade, e em caráter coletivo. Os resultados indicaram que o principal problema enfrentado na área de pesquisa, foi à ausência de saneamento básico acarretando inundações, alagamento.

Detection and quantification of heavy metals in blood and milk of Amazon river dolphin (Inia geoffrensis) (Cetartiodactyla: Iniidae) using wavelength‐dispersive X‐ray fluorescence spectrometry

“…equal to 50 and 30 μg/g, respectively, which is higher than the limits allowed by Brazilian legislation. However, in the Cassiporé River, Lima et al 49 analyzed 55 fish species, some of them known prey of Amazon river dolphin 37 and did not observe concentrations of copper and zinc above the limits allowed by Brazilian legislation. However, in this study, the concentrations of copper and zinc in the blood and milk samples of a female Amazon river dolphin were higher than the limits allowed by Brazilian legislation.…”

“…The Amazon river dolphin is a top predator that consumes at least 43 fish species from 19 different families. 37 Many of them occur in the water bodies of the MSDR. 38,39 Thus, the concentrations of heavy metals in the milk of female Amazon river dolphin in this study may be a consequence of the metals transferred via food and bioaccumulation during the lactation period, which can last, on average, 2.8 years in Inia geoffrensis.…”

“…1 The analysis of prey tissue can be a powerful tool to assess the health risks for cetaceans when they are subjected to chemical exposure, according to Lin et al 42 Studies on contamination by heavy metals in fish from the MSDR region have not been performed to date. However, studies considering other regions of the Amazon basin have shown that many fish species, including those that are known prey of Amazon river dolphin, 37 present high concentrations of heavy metals bioaccumulated in their tissues (e.g., cadmium, chromium, copper, lead, zinc, and mercury), both in areas with high mining activities (e.g., Madeira, Tapaj os, and Cassiporé Rivers) and in areas with low mining activities (e.g., Negro River). [43][44][45][46][47][48][49][50][51][52][53] Some studies reported that fish from floodplain lakes have high levels of Na, K, Cl, Ca, and Mg in their blood plasma and tissues (muscle, gills, and liver).…”

“…are known prey of Amazon river dolphin and occur in the aquatic environment located at the MSDR. [37][38][39] Thus, the high concentrations of these metals in the blood and milk of female Amazon river dolphin (e.g., potassium, chlorine, and calcium) suggest a response to a diet based on fish containing high levels of these metals in their organisms. Some species or genera (e.g., Pimelodus blockii, Crenicichla, Leporinus, Pellona, Sarrasalmus, Potamorhina, and Cichla), which are also known prey of Amazon river dolphin and occur in the aquatic environment at the MSDR, [37][38][39] presented levels of chromium in their tissues higher than the limits allowed by Brazilian legislation (0.1 μg/g).…”

Yehudei amazonya: vivências, práticas religiosas e representações simbólicas

“…Esse foi o contexto em que a Amazônia começou a ser colonizada, cujo momento histórico foi marcado pelas disputas econômicas e políticas que atendiam aos interesses dos países ibéricos, bem como de outros países europeus. Vinculado a esse empreendimento, que interferiu diretamente no território, na vida e na organização dos povos originários da Amazônia, estava o cristianismo católico (Silva, 1996).…”
