[ 1 ] - A new method to consider spatial risk assessment of cross-correlated heavy metals using geo-statistical simulation
The soil samples were collected from 170 sampling stations in an arid area in Shahrood and Damghan, characterized by prevalence of mining activity. The levels of Co, Pb, Ni, Cs, Cu, Mn, Sr, V, Zn, Cr, and Tl were recorded in each sampling location. A new method known as min/max autocorrelation factor (MAF) was applied for the first time in the environmental research works to de-correlate these ...
[ 2 ] - A comparative study of performance of K-nearest neighbors and support vector machines for classification of groundwater
The aim of this work is to examine the feasibilities of the support vector machines (SVMs) and K-nearest neighbor (K-NN) classifier methods for the classification of an aquifer in the Khuzestan Province, Iran. For this purpose, 17 groundwater quality variables including EC, TDS, turbidity, pH, total hardness, Ca, Mg, total alkalinity, sulfate, nitrate, nitrite, fluoride, phosphate, Fe, Mn, Cu, ...
[ 3 ] - Concentration of Heavy Metals in Soil and Staple Crops and the Associated Health Risk
Background & Aims of the Study: The main objectives of the current research were (1) to study the extent of soil pollution by heavy metals (Ag, Cd, Cr, Cu, Mn, Ni, Pb, Zn, Ba and Li) in sampling locations (2) to investigate the extent of heavy metal pollution and soil to plant transfer of these elements in wheat and barley (3) to study the health risk of heavy metals via consum...
[ 4 ] - تغییرات پارامترهای کیفی آب زیرزمینی در محدوده شهرستان ملایر با تاکید بر تاثیر کاربری کشاورزی بر کیفیت آب
هدف مطالعه کنونی بررسی کیفیت آب زیرزمینی در محدوده شهرستان ملایر، استان همدان، براساس اطلاعات پایش شده در یک دوره زمانی چهار ساله و با توجه به شاخص کیفیت آب با تاکید برتاثیر کاربری کشاورزی برکیفیت آب بوده است. داده های پایش شده در ارتباط با 14 پارامتر کیفیت آب مربوط به 26 چاه در طی سالهای 1392-1391 و 19 چاه طی سالهای 1390-1389 بدست آمدند. میزان باقی مانده کلر در 50 درصد از ایستگاهها در حد ص...
[ 5 ] - Accumulation and Soil-to-Plant Transfer Factor of Lead and Manganese in some Plant Species in Semnan Province, Central Iran
Background: Heavy metals have detrimental effects on the health of human being. The values of manganese (Mn) and lead (Pb) in some plant species and soil samples in an arid area of Iran were evaluated in this study. Methods: The values of Pb and Mn in 94 plant samples from 8 plant species and the related soil samples in 2010 were considered in Shahroud and Damghan, central Iran. Moreover, th...
[ 6 ] - Health Risk Assessment of Fe, Mn, Cu, Cr in Drinking Water in some Wells and Springs of Shush and Andimeshk, Khuzestan Province, Southern Iran
Background: In the current study,the hazard quotient, the hazard index (HI) and spatial variations of Fe,Mn,Cu and Cr in drinking water sources of Andimesk-Shush, Khuzestan Province, Southern Iranaquifer were assessed. Methods: We compared theconcentrations of aforementioned heavy metals in wells and springs inAndimeshk and Shush regions. The non-carcinogenic risk assessment of heavy metals ...
