Ocorrência de metais pesados no curso inferior do rio Ivaí, em decorrência do uso do solo em sua bacia hidrográfica

Abstract: Nas últimas décadas, a bacia do rio Ivaí, notadamente na região do Terceiro Planalto Paranaense, vem sofrendo os mais variados tipos de agressões. Esses impactos se refletem nas alterações das características físicas, químicas e biológicas naturais. Neste sentido, ao longo de seis meses, foram feitas cinco coletas de amostras compostas, de água, nas estações de coleta localizadas nos municípios de Icaraíma, Herculândia e Tapira (Estado do Paraná). Na coleta, foram medidos: pH, temperatura, transparência, oxigê… Show more

“…This trace metal is very toxic (Türkmen et al, 2008), being able to alter brain morphology and cause edema and hemorrhage in this organ (Adeyemo, 2008), besides the effects on the liver and hematologic parameters . Some studies developed in Brazil (Ramalho et al, 2000;Guedes et al, 2005) and specifically in Parana state (Santos et al, 2008) detected lead concentrations above the established by CONAMA (Conama, 2005), that is concern scenario, because the fishery is also a routine in this region.…”

“…Several polluting sources still can have contributed to the identified change, since according to Santos et al (2008) and Ramalho et al (2000), the Pb takes part of the composition of several products, such as welds, inks, plumbing, fuel, pesticides containing lead arsenate etc.…”
