Background & Aims of the Study: The objective of this study was to investigate the seed pre-treatment with salicylic acid (SA) on tolerance and remediation ability of Brassica oleracea var. acephala under lead and zinc stresses. Materials and Methods: Present study was conducted to evaluate phyto-accumulative ability of Brassica oleracea var. acephala in heavy metal concentrat...

aim: this study was conducted to investigate the accumulation of three heavy metals including lead, tin and zinc in the liver and muscle tissues of 60 silver carp (hypophthalmichthys molitrix) collected from different stations of the anzali wetland (located at the west south of caspian sea): pirbazar, anzali, khazarvila, beshman, sangachin and abkenar, in april 2011. materials and methods: samp...

pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (edta) on some morphological characteristics of thlaspi caerulescens l., and also on the accumulation of lead (pb) and zinc (zn) in roots and shoots of t. caerulescens l.. experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of edta and control pots (c: uncontaminated so...

Soil contamination with potentially toxic elements (PTEs) in agricultural lands, in part, is responsible for limiting the crop productivity and the food chain contamination. The objective of this study were to asses the limiting of crop productivity by cadmium (Cd) and lead (Pb), the potential transfer and bioaccumulation of these PTEs in plants, and ultimately the food chain contamination to e...

the pollution of soil by heavy metals is considered to be quite a big problem in many areas ofthe world. to limit the accumulation of lead and cadmium from soil in the products, a correct understanding ofthe characteristics and specifications of the translocation of cadmium and lead is necessary. in order to evaluatethe effects of cadmium and lead interaction on zinc and manganese concentration...

s: Lead-arsenate was used to control codling moth (Cydia pomonella) in apple (Malus sylvestris Mill) orchards from the 1900’s to the1960’s. Lead and arsenic are generally immobile and remain in the surface soil. Some orchard lands are being used for vegetable crop production. There are concerns of lead and arsenic accumulation in vegetables crops grown in these soils. Objectives were to 1) dete...

Road transport is a ubiquitous source of lead contamination in the soil near highways with direct and indirect impacts on human health. Accumulation of traffic-induced lead in the soils depends on gasoline lead content, traffic volume, as well as meteorological conditions. To evaluate the effect of traffic on soil lead concentration, 113 samples from the topsoil (0-15 cm) were collected in a re...

In desert reclamation strainer plants can be used for improvement and decrease pollution of soil and water. This technology can be used to remove both inorganic and organic contaminants in soil. In this study, one year old Acacia victoriae seedlings were exposed to Pb (NO3)2 in 5 different concentrations; 0, 50, 250, 500 and 1000 mg Pb L-1 for 45 days in two growing seasons. Subsequently, the h...

Phytoextraction is gaining acceptance as a cost-effective and environmentally friendly phytoremediation strategy for reducing toxic metal levels from contaminated soils. Cognizant of the potential of this phytoremediation technique as an alternative to expensive engineering-based remediation technologies, experiments were conducted to evaluate the suitability of some plants as phytoextraction s...
