Background and Objectives: Soil polluted with total petroleum hydrocarbon (TPHs) is a great threat to human health. Phytoremediation, the use of vegetation for treatment of contaminated soils, is an attractive and cost-effective alternative to reduce pollutant from soil. This paper evaluates the effects of the plant and nutrients on the removal of TPHs from soil. Material and methods: Soils wer...
background & aims of the study: heavy metals contaminate drinking water, air and soils. it is very harmful for humans and other live organisms. phytoremediation is one of the direct bio-remediation methods for heavy metal removal from polluted water and soils. this method is accepted environmentally, economically and aesthetically. the purpose of this study was to assess tamarix hispida capacit...
ABSTRACT Soil erosion is one of the fundamental issues in the fields of environmental , natural resources and agriculture. And today know this topics and related issues that should be considered to take over. using Of new method Instead of traditional methods in order understanding and applying appropriate planning is essential. The aim of this study review Erodibility and Boir Ahmad province u...
ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
Some industrial processes, such as plating and gold mining, utilize cyanide, which entering in their effluents. Because cyanide compounds are toxic contaminants, the waste-containing cyanide must be treated before discharge in the environment. Several methods are available for cyanide removal or detoxification. Natural degradation, alkaline chlorination, and oxidation with hydrogen peroxide a...

Vulnerability of soil separates to detachment by water is described as soil erodibility by Universal Soil Loss Equation which can be affected by land use change. In this study it was attempted to quantify the changes of Universal Soil Loss Equation K-factor and its soil driving factors in three land uses including rangeland, rainfed farming, and orchards in Babolrood watershed, northern Iran. S...
Finding an appropriate method with the highest rate of polycyclic aromatic hydrocarbon (PAH) removal from naturally polluted soils is important research issue. A pot factorial experiment (using contaminated soil samples Isfahan Refinery, Iran) was conducted in a 90-day period to compare following bioremediation strategies: (1) natural attenuation (NA): inherent ability for bioremediation; (2) b...
