Phytorestoration of DDT-contaminated soil by pumpkin
نویسندگان
چکیده
To choose cucurbitaceous plant pumpkin as the selected plant and the paper initially discussed on the repair effects of DDT-contaminated soil by pumpkin under a variety of measures. Results showed that the content of DDT in soil reduce significantly after the same repair period. The experimental group which have the most obvious repair effect has two kinds of bacteria for control measures. The second one added compound fertilizer as measures.

Effects of Soil Oxygen Conditions and Soil pH on Remediation of DDT-contaminated Soil by Laccase from White Rot Fungi
High residues of DDT in agricultural soils are of concern because they present serious threats to food security and human health. This article focuses on remediation of DDT-contaminated soil using laccase under different soil oxygen and soil pH conditions. The laboratory experiment results showed significant effects of soil oxygen conditions and soil pH on remediation of DDT-contaminated soil b...
متن کاملResistance of microbial populations in DDT-contaminated and uncontaminated soils
One DDT-contaminated soil and two uncontaminated soils were used to enumerate DDT-resistant microbes (bacteria, actinomycetes and fungi) by using soil dilution agar plates in media either with 150 mg DDT ml−1 or without DDT at different temperatures (25, 37 and 55◦C). Microbial populations in this study were significantly (p<0.001) affected by DDT in the growth medium. However, the numbers of m...
متن کاملBioremediation of Cd-DDT co-contaminated soil using the Cd-hyperaccumulator Sedum alfredii and DDT-degrading microbes.
The development of an integrated strategy for the remediation of soil co-contaminated by heavy metals and persistent organic pollutants is a major research priority for the decontamination of soil slated for use in agricultural production. The objective of this study was to develop a bioremediation strategy for fields co-contaminated with cadmium (Cd), dichlorodiphenyltrichloroethane (DDT), and...
متن کاملDechlorination of DDT, DDD and DDE in soil (slurry) phase using magnesium/palladium system.
Mg0/Pd4+ was able to dechlorinate >99% of extractable DDT (initial concentration of 10 mg DDT kg(-1) of soil) and >90% of extractable DDT (initial concentration of 50 mg DDT kg(-1) of soil) in soil slurry. Mg0/Pd4+ was also found to be effective in dechlorinating of 50 mg kg(-1) DDD and DDE, in soil aged for varying time periods. GC-MS analyses revealed the formation of 1,1-diphenylethane as an...
متن کاملUtilizing thin-film solid-phase extraction to assess the effect of organic carbon amendments on the bioavailability of DDT and dieldrin to earthworms.
Improved approaches are needed to assess bioavailability of hydrophobic organic compounds in contaminated soils. Performance of thin-film solid-phase extraction (TF-SPE) using vials coated with ethylene vinyl acetate was compared to earthworm bioassay (Lumbricus terrestris). A DDT and dieldrin contaminated soil was amended with four organic carbon materials to assess the change in bioavailabili...
