The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the perio...

Lead, ubiquitous in the environment as a result of mining and industrialization, is found as a contaminant in humans although it has no known physiological function there. Lead-exposed children are known to be the population with the highest potential health risks. The recommended biomarker to assess environmental lead exposure in animals is lead level in blood. Before 2001, the Department of T...

OBJECTIVE To estimate the prevalence of lead poisoning in children and to identify associated factors, as well as possible local sources of contamination. METHODS A cross-sectional prevalence study conducted in 2006 with a random sample of 97 children age zero to five years from a neighborhood in Porto Alegre, Southern Brazil. Blood lead levels were measured and a questionnaire administered t...

Urban air pollution is widely recognized. Recently, there have been a few projects that examined air quality in rural areas (e.g., AUPHEP project in Austria, WOODUSE project in Denmark). Here we present the results within the International Cooperation Project RER/2/005 targeted at studying the effect of local combustion processes to air quality in the village of Brzezina in the countryside nort...

Blood samples of 160 children, ranging age between 3 months and 6 years were selected from five different parts of Amritsar district of Punjab (India) and were analyzed for Zn, Cd, Pb and Cu using anodic stripping voltammetry. Large variations in the results have been correlated to the area inhabited, age differences and other factors. It was found that the areas, more prone to environmental st...

Changes in environmental pollution by S, Cd, Cu, Pb and Zn in 2006-2014 were evaluated using a bioindication method. This method was based on measurements of pollutants in Scots pine (Pinus sylvestris L.) needles. The measurements were performed in the Chojnowskie Forests, a region recognized as a background area for central Poland. The changes in the contents of sulfur (S) and metals in needle...

background and purpose: in the process of rapid urbanization and industrialization in developing countries, environmental pollution is a major concern. one of the fastest growing problems of environmental pollution is an excessive intake of lead in urban soils. lead concentrations in urban soil may result from human activities such as vehicle emissions and industrial activities. this study aime...

background bivalves have been used to study pollution level caused by heavy metals due to their biological characteristics. bahrakan region includes bahrakansar, hendijan, norouz and soroush oil fields, and current information regarding sea management, especially from the protective aspect is very little. objectives this study aimed to assess region pollution with heavy metals. for this purpose...
