Spectrometric Methods Used to Determine Heavy Metals and Total Cyanides in Accidental Polluted Soils

Bacterial Community DNA Extracted from Soils Polluted with Heavy Metals

This paper describes the application of two direct and one indirect methods for the extraction of microbial community DNA from soils polluted with heavy metals. DNA was extracted directly from soil using a gentle method based on soil incubation at 37°C with proteinase K and SDS, or the method was modified by the addition of a bead beating step. The indirect approach was based on the RNA/DNA ext...

Phytoremediation of soils polluted by heavy metals using Vetiver grass and Tall Fescue

Phytoremediation is a biological method to improve soils contaminated with heavy metals. The objective of the present research was to study the capability of Vetiver grass and Tall Fescue in refining and reducing pollution of Cd, Cu and Zn from contaminated soils. The research was implemented in greenhouse during two separate tests (Vetiver grass and Tall Fescue) in a completely randomized desi...

Developing Preparation Methods for Biological Samples to Determine Trace Amounts of Heavy Metals: A Review Study

Introduction: Perpetration of samples is one of the most important stages needed for trace residue analysis of biological specimens when human exposure assessment is required. The samples preparation process makes the analyte get more purified and enriched as well as more compatible to the analysis instrument systems. The present study has concentrated on a systematic review of different articl...

Phytoremediation of heavy metals polluted environments

The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...
