Long-term contamination of the marine environment surrounding a lead smelter offered a unique opportunity to examine how pollutants might have acted to alter genetic characteristics of populations of organisms in the receiving system. This study used random amplified polymorphic DNA analysis to compare the genetic diversity of populations of the prawn, Leander intermedius, and the isopod, Platy...

Mining industries and metal refineries represent an important economic sector for many countries. However, environmental issues are gaining interest and sustainable development requires that metal industries minimize threats for air, water and soil quality. For years, smelters represented the dominant sources of metals and SO2 released to the environment in Canada. Recently, the smelter operato...

We compared high-precision lead isotopic ratios in deciduous teeth and environmental samples to evaluate sources of lead in 10 children from six houses in a primary zinc-lead smelter community at North Lake Macquarie, New South Wales, Australia. Teeth were sectioned to allow identification of lead exposure in utero and in early childhood. Blood lead levels in the children ranged from 10 to 42 m...

Abstract Potentially toxic elements (PTEs) were investigated in the different sizes of road deposited sediments (RDS) around active smelting industry to understand their sources and assess pollution ecological risk levels. The highest PTEs concentrations was shown near raw materials import port facilities. fine particles RDS showed extremely high concentrations. Zn has mean concentration < 6...

In this paper, we present an analysis of the pollution surface water and air by heavy metals: Mn, Fe, Ni, Cu, Zn, Cd Pb in area smelter Ozimek (Opolskie Voivodeship, Poland). The marine algae Palmaria palmata was exposed Mała Panew River, three species forest mosses: Pleurozium schreberi, Sphagnum fallax Dicranum polysetum were also applied. Active biomonitoring carried out using P. schreberi m...

This paper proposes the use of Bayesian belief networks (BBN) as a higher level of health risk assessment for a dumping site of lead battery smelter factory. On the basis of the epidemiological studies, the actual hospital attendance records and expert experiences, the BBN is capable of capturing the probabilistic relationships between the hazardous substances and their adverse health effects, ...

Occupational exposure to arsenic has been associated with cancer of the lung, but epidemiological studies of cancer of the lung and environmental exposure to arsenic have produced conflicting results. Case-control studies about point sources of pollution have been useful in identifying environmental hazards. This technique was used to evaluate the risk for lung cancer near a smelter in El Paso,...

Human activities have led to a considerable increase in trace metal cycling recent times. The mobilized elements get subjected variety of processes leading eventually their re-concentration. polluted sites, transformed by Earth's surface processes, become similar accumulations known from geological records. This study examines authigenic sulfide mineralization two peatlands atmospheric depositi...
