Caracterização geoelétrica de área de curtume localizada no distrito industrial de Icoaraci, Bélem-Pará

Abstract

ABSTRACT.A study covering the shallow subsurface was performed in order to investigate the possibility of underground contamination by liquids used in the industrial processing of dead animal skin to produce tanned hide. The study was carried out inside the area of the Couro do Norte industry, located in the Icoaraci Industrial District (Belém-PA). The used geophysical methodology was: resistivity (imaging and vertical electric soundings), spontaneous potential, electromagnetic (slingram) and ground penetrating radar (GPR). The integrated geophysical interpretation of data indicated the underground flow direction and a shallow plume of contamination, caused probably by the disposal of effluents by the Couro do Norte industry.

Wastes released by tanneries at Patrocínio Paulista, São Paulo State, Brazil

“…This may be illustrated by the results of a study carried out inside the area of the Couro do Norte industry, located in the Icoaraci Industrial District (Belém-PA) [16]. The investigation covered the shallow subsurface and was performed in order to investigate the possibility of underground contamination by liquids used in the industrial processing of dead animal skin to produce tanned hide.…”

“…A review of the total pollution load decrease achievable according to the UNIDO [17] posts precise data on the abatement achievable through industrially proven low-waste advanced methods. It has been pointed out that [16] "even though the chrome pollution load can be decreased by 94% on introducing advanced technologies, the minimum residual load 0.15 kg/t raw hide can still cause difficulties when using landfills and composting sludge from wastewater treatment on account of the regulations currently in force in some countries.

Bioassay using Daphnia magna Straus, 1820 to evaluate the sediment of Caí River (Rio Grande do Sul, Brazil)

“…Hg and Ni were looked at because they are potential pollutants in this area, but they were not detected. Ni can be found in effluents from metallurgical industry and according to Evens et al (2009) it causes a significant reduction in the reproduction of D. magna in the 21-day test, while Nunes and Luiz (2006) report the presence of Hg in tannery effluents.…”

“…Other metals researched, Hg and Ni, were not detected, but the search for these two metals was based on the fact that the former is a secondary contaminant in tanneries (Nunes and Luiz, 2006) and the latter is a common pollutant in metallurgical industry effluents (Nascimento and Naime, 2009).…”

Evidências tectônicas no leste da Ilha do Marajó: integração de dados morfoestruturais e geofísicos

“…hidrogeologia, mapeamento de estruturas geológicas e no meio ambiente. No Brasil é amplamente usada em terrenos sedimentares para distinção de lençol freático e locação de poços, e possíveis plumas de contaminação (p.e., Porsani, 1981;Mendes & Verma, 2002;Bahia, 2003;Nunes, 2005;Souza & Verma, 2005;Freitas Filho, 2006;Olívia & Kiang, 2007;Costa & Malagutii Filho, 2008). Num contexto mundial este método tem incessante aplicação no mapeamento e delineamento de corpos geológicos e feições tectônicas em zonas de tectônica extensional a fim de demonstrar movimentos tectônicos recentes e seu efeito em terremotos fortes (p.e., Jie et al 2002;Özürlan et al 2006).…”
