Abstract
The inadequate disposal of solid urban waste has been of concern, due to the possibility of environmental contamination by various toxic substances, such as heavy metals. The study aims to analyze the concentration of heavy metals in soil and water samples collected around the municipal solid waste (MSW) open dumpsite, Iguatu, Ceará, Brazil. The analysis of risk to human health was determined using Hazard Quotient (HQ). The results showed the presence of heavy metals in concentrations higher than those established by current legislation. The concentration of metals in the soil and water samples were found in the following order, respectively: Fe> Zn> Mn> Cu> Pb> Cr and Fe> Mn> Zn> Ni> Cu> Cr> Cd> Co. However, HQ values indicate that the level of these metals may have little or no adverse health effects. The results suggest the continuous monitoring of the environmental matrices, to avoid the increase of contamination and the risk to human health.
期刊介绍:
Journal of Urban and Environmental Engineering (JUEE) provides a forum for original papers and for the exchange of information and views on significant developments in urban and environmental engineering worldwide. The scope of the journal includes: (a) Water Resources and Waste Management [...] (b) Constructions and Environment[...] (c) Urban Design[...] (d) Transportation Engineering[...] The Editors welcome original papers, scientific notes and discussions, in English, in those and related topics. All papers submitted to the Journal are peer reviewed by an international panel of Associate Editors and other experts. Authors are encouraged to suggest potential referees with their submission. Authors will have to confirm that the work, or any part of it, has not been published before and is not presently being considered for publication elsewhere.
