The purpose of this study was to investigate the regional Cadmium (Cd) concentration levels in soils and in leaf vegetables across the Pearl River Delta (PRD) area; and reveal the transfer characteristics of Cadmium (Cd) from soils to leaf vegetable species on a regional scale. 170 paired vegetables and corresponding surface soil samples in the study area were collected for calculating the tran...

PICT (Pollution Induced Community Tolerance) to Cu is a useful and sensitive tool assess the effects of pollution in soils under laboratory conditions. However, field situations, absence reference values, i.e. bacterial community tolerance baseline from non-polluted soils, make method uncertain when we want know if soil or not polluted microbiological point view. In order shed some light on thi...

This study summarizes the main results obtained by the research group from the Instituto de Recursos Naturales y Agrobiología de Sevilla during ten years of study in the mine spill affected area of the Guadiamar river (SW Spain). This work is focussed on 1) trace element changes in soil (total and available concentrations) and plants (native and reforested), and 2) evaluation of the effectivene...

treatment of soils contaminated with heavy metals using plant species is a method which has been widely used in thepast. this method, which is known as phytoremediation, has been applied for pollution treatment using different plantspecies worldwide. the method has been used for remediation of various types of pollutants in laboratory, pilot andindustrial scales. the aim of this study was to co...

Plant-based environmental remediation, or phytoremediation, has been widely pursued in recent years as a favorable clean-up technology and is an area of intensive scientific investigation. For the vast majority of field applications, vegetative 'phyto-crops' are selected specifically for their capacity for site decontamination and not for additional concurrent or post-remediation utility. By co...

Long-term and excessive application of chlorimuron-ethyl has led to a series of environmental problems. Strain Hansschlegelia sp. CHL1, a highly efficient chlorimuron-ethyl degrading bacterium isolated in our previous study, was employed in the current soil bioremediation study. The residues of chlorimuron-ethyl in soils were detected, and the changes of soil microbial communities were investig...

A PCR identification method in which four primers that recognize homologous conserved regions in the Sinorhizobium meliloti genome are used was developed and tested. The regions used for identification were the nodbox 4 locus, which is located in one of the symbiotic megaplasmids, and the mucR gene, which is located in the chromosome. The new method was used to establish a collection of S. meli...
