Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...

Many studies indicated that industrialization and urbanization caused serious soil heavy metal pollution from industrialized age. However, fewer previous studies have conducted a combined analysis of the landscape pattern, urbanization, industrialization, and heavy metal pollution. This paper was aimed at exploring the relationships of heavy metals in the soil (Pb, Cu, Ni, As, Cd, Cr, Hg, and Z...

abstractbackground and objectives: considering progressive growth of industry and technology, the accumulation of environmental contaminants, especially heavy metals (hms) in the soil is of increasing worldwide concern about the probable soil pollution risks. the perception of pollutants spatial distribution pattern and recognition of factors which control this pattern and identification of pro...

Using the methods of soil analysis and geostatistics combined with GIS, this paper determined and mapped the spatial distribution of soil DTPA-extractable copper (Cu) in cultivated fields of Shenyang suburbs of China, aimed to assess the roles of industries and agricultural managements in affecting the spatial heterogeneity of soil Cu in this region. The results showed that the soil DTPA-extrac...

One of the main environmental problem that need efficient software tools is the prediction problem. More concrete, it can mean meteorological prediction, air/soil/water pollution prediction, flood prediction and so on. In the last decade several methods based on artificial intelligence were proposed by taken into account that they can offer more informed methods that use domain specific knowled...

The forecasting problem is one of the main environmental problems that need efficient software tools. More concrete, it can mean meteorological/weather forecasting, air/soil/water pollution forecasting, flood forecasting and so on. Several methods based on artificial intelligence were proposed by taken into account that they can offer more informed methods that use domain specific knowledge, an...

Understanding spatial and temporal variations in river water quality and quantitatively evaluating the trend of changes are important in order to study and efficiently manage water resources. In this study, an analysis of Water Pollution Index (WPI), Daniel Trend Test, Cluster Analysis and Discriminant Analysis are applied as an integrated approach to quantitatively explore the spatial and temp...

conclusions it can be concluded that residential-road land uses show the considerable pollution index and ecological risk. materials and methods soil samples were collected from a depth of 0-20 cm at 16 stations with different users. the samples were passed through a 2-mm sieve after air drying. to determine the concentration of heavy metals, the samples were extracted by acid chloride and nitr...

a study was carried out in malawi to determine the levels of heavy metals in cabbages grown in gardens irrigated with reservoir and tap water. the concentrations of cadmium, lead and chromium were determined in the leaf and in the corresponding soils in order to assess whether the amounts in the soils reflected the accumulation of heavy metals in plants. the results showed that the levels of th...

the purpose of this research was to investigate the attitude of vegetable growers towards sources of soil pollution in ray county. the study consisted of all vegetable growers (n=700) in ray county, located in tehran province, from which 70 vegetable growers were selected through random sampling technique. a planned questionnaire was used as the main instrument to collect data. the content vali...
