Tissue kinetics of heavy metal and boron accumulation, in the recovery of industrial sewage sludge by superplants

Abstract

The overall pollution in the planet is reaching unbearable limits for humanity. Never before mankind had come to adopt measures agreed between countries in the magnitude of current ones. Among the measures taken to alleviate the problem are increasing green alternatives. This paper aims reporting how green alternative using Genetically Modified Organisms (GMOs) which have proven over last decade to be by far the best overall tool for combating pollution, operate in more detail. A kinetic study of heavy metals (Ni, Cu, Zn, Cd, Pb, and Hg) and B accumulation by plants grown in sludge collected from a treatment plant of industrial sewage is carried out. Summarizing: the results investigated in this work confirm again the capacity and usefulness of this tool as a solution to global pollution problems, studying another specific case which is particularly interesting since provides a real solution for a common problem: industrial water sludge. In this manner, substantiating the strategy designed in a scientific project (triggered by Doñana's disaster) granted by UE funds in 2000, and presented in Hanover’s Universal Exposition. Glossing and discussing its positive implementation during years to check out the so called superplants against pollution.
