Phytoremediation of aromatic pollutants and selection of elite clones
1997
Shetty, K. | Nadiga, M. | Zheng, Z. | Lanza, G.R. (University of Massachusetts Amherst, Massachusetts (USA). Lab. of Food and Environmental Biotechnology)
Technology options involving the use of natural and accelerated bioremediation systems to treat complex mixtures of aromatic wastes would be a useful addition to current remediation strategies. The approach outlined in this paper would focus on harnessing the potential of a key detoxification enzyme, glutathione-S-transferase (GST) as part of an accelerated phytoremediation system to detoxify aromatic pollutants in soil and ground water. Major efforts will include the clarification of GST detoxification activity by characterizing the enzyme in a series of phenolic and azo-dye-tolerant phytoremediation candidates (e.g. elite clones of thyme), and the development of methods to manipulate the GST detoxification pathway in elite plant clones to accelerate the detoxification of aromatic pollutants. The information provided by the GST characterization studies could be used to develop significant new phytoremediation systems based on manipulated GST biotransformation pathways in elite plant clonal systems tolerant to highly polluted environments. One major advantage of the new phytoremediation systems would be their potential to perform in highly contaminated environments by providing a favorable rhizophere zone for microbial degradation of aromatics along with an enhanced GST-linked detoxification pathway

The paper deals with determination of the economic elements of water management, which reflect the specific foundations, processes, principles and goals that are determined by the water policy. In terms of services, this represents the economic valorization of the foundations in manageable and unmanageable technical and natural systems, in which processes take place to bring water to a certain target quantity and quality, as well as provide safety against water in time and space. The use of, and protection against water, are under the pressures and influence of natural climatic and soil factors, the balance condition of surface and groundwater, and in particular human activities and demands for the characteristics of water in a water body, water area and in the river basin. These factors influence the demand for services, which also depends on the available domestic product, its volume of use, tastes and preferences. The offer consists of services for a particular quantity and quality of the available water, and for a certain degree of safety from the harmful effects of water, which are achieved by the employees of the functional facilities and systems. Together with the activities of the association, population and public services, the use of, and protection against water make up the totality of water management. It requires a decision process in all of the functions involved in planning, organization, management and control. Water management is identified with the water policy and activity, although there is a difference between them. The first is represented by a decision-making system in planning, organization, management and control, while the second is represented by the activity systems of government in the field of protection against water, as well as the protection and use of water. The activity consist of certain services which are performed by the employees of the companies, through the provision and performance of water management services in various time and space, in accordance with the offer and the demands of the users.

[Wastewater management in the aluminium industry as a new approach to the control of surface and underground waters pollution]
2003
Perovic, S. (Kombinat aluminijuma, Podgorica (Serbia and Montenegro)) | Kolinovic, R. | Grzetic, I.
Processes like QMS (Quality management systems) and EMS (Environmental management systems) consist of series of procedures/elements, among which are operative or working procedures. One of these procedures is control of waste waters from the Aluminium Plant in Podgorica, Montenegro (Serbia&Montenegro). This procedure controls the order of activities, the responsibility, the input and output documents, with the exclusive aim to measure the effects of protection of surface and underground waters and to review the EMS of the company for the waste waters.
