Since then, phytoremediation acquired the status of a proven technology for the remediation of soil and groundwater contaminated by a variety of organic compounds, including pesticides, chlorinated solvents, explosives, polyaromatic hydrocarbons (pahs), dioxins, and polychlorinated biphenyls (pcbs) (1,4–7. Phytoremediation of polychlorinated biphenyls: new remediation strategies: low cost because of the absence of energy-consuming equipment and limited maintenance, no or limited negative impact on the environment because of the in situ nature of the process, and large public acceptance. Remediation of polychlorinated biphenyls page: 1 1 o introduction/purpose this proposal will briefly describe the fundamental strategy that will be used to evaluate and remediate.

Di toro, s, zanaroli, g, and fava, f, intensification of the aerobic bioremediation of an actual site soil historically contaminated by polychlorinated biphenyls (pcbs) through bioaugmentation with a non acclimated, complex source of microorganisms, microbial cell. Abstract polychlorinated biphenyls (pcbs) are serious environmental pollutants that threaten both the natural ecosystem and human health for remediation of environments contaminated with pcbs, several approaches that exploit the potential of microbes to degrade pcbs have been developed.
Soil from a site heavily contaminated with polychlorinated biphenyls (pcbs) was treated with a pilot‐scale, solvent extraction technology bioassays in earthworms and plants were used to examine the efficacy of the remediation process for reducing the toxicity of the soil. Biological remediation of polychlorinated biphenyls (pcb) in the environment by microorganisms and plants the environment is suffering severe contamination as a result of various uncontrolled activities of man and chemicals in the biosphere. Technologies such as thermal, oxidative, reductive, and microbial methods for the remediation of polychlorinated biphenyls (pcbs) have previously been reviewed based on energy consumption, formation of pcdd/f, and remediation efficiency, reductive methods have emerged as being advantageous for remediation of pcbs.
