Moldova Technologies The Application of Phytoremediation for DDTs Polluted Site Decontamination
The Application of Phytoremediation for DDTs Polluted Site Decontamination
Description
The main scientific directions are study of the geology and geophysics conditions of the Republic of Moldova. Environmental geochemistry of persistent organic pollutants, petrol pollutants (PAHs, BTEX etc.), and heavy metals are principal study topics of institute for water quality and environmental risk assessments, implementation of site remediation technologies. Investigation of the destructive geological phenomena also is in the filed of scientific interest of institute for sustainable development of the country and minimization of negative impact of different pollutants on environmental quality and public health.
Institute possesses sufficient laboratory capabilities and experience for analytical work by the environmental investigation:
- Determination of chlororganic pesticides, polichlorbiphenyls (PCBs) polyaromatic hydrocarbons (PAHs), BTEX;
- Identification of compounds in different objects by Gas Chromatography – Mass Spectrometry;
- Analysis of toxic elements (As, Se, Hg, Pb, Cd, Cu, Zn, Ni, Cr, Al, Mn, Fe, V, Si etc.) in natural and technological waters, foods, agriculture crops, soils, sediments, sewage sludge, metals and alloys.
Innovative Aspect and Main Advantages
The methodology for the inventory of POPs polluted areas, Environmental Risk Assessment procedure and phytoremediation technology in Moldova conditions has been developed. The phytoremediation experiment has been de-signed using five plant species: corn (Zea mays L.), zucchini (Cucurbita pepo L. subsp. pepo), pumpkin (C. pepo L. subsp. pepo), carrot (Daucus carota L.subsp. sativus (L.) Schubler & G.Martens.), and sorghum (Sorghum bicolor L. Moench). The principal plant parts have been analyzed for the assessment of pesticide accumulation (roots, steam, leaves, crop). Conclusion has been made that old pesticide storages with a relative high level of POPs pollution can be cleaned by the phytoremediation technology. It needs individual design for every lot in view of local conditions. Investigators should take into consideration all advantages and limitations of this technology and use it in complex with other biotechnology for more effective POPs destruction.
Areas of Application
An environmental friendly technology has been devel-oped for the polluted site remediation. Proposed technol-ogy is a development of EPA method of phytoremedia-tion. Zucchini and pumpkin showed good results in Mol-dova conditions for the implementation of phytoremediation technology for POPs removal from soil. Local wild plants can be used also for this purpose in complex with cultivated plants. These approaches will give better results in complex utilization with other biotechnology (microbiological destruction).
