“…Tolerance of Artemia sp. specimens makes this genus adaptable to a great variety of testing conditions in estuarine, marine or hypersaline environments, from 2 to 204 g L À1 of salt, thus responding to the actual demands of standardised tests for brackish and saline ecosystems [20][21][22][23][24][25].…”

It is known that the compound 2,4-dichloro-6-nitrophenol (2,4DC6NP) is formed upon nitration of 2,4-dichlorophenol, which in turn is a transformation intermediate of the herbicide dichlorprop. However, the chemical and spectroscopic characteristics of 2,4DC6NP, as well as its toxicity, are poorly known. This work shows that 2,4DC6NP behaves as a diprotic acid in aqueous solutions, with pK a values of 3.0 AE 0.9 and 4.9 AE 0.5. At pH < 3, 2,4DC6NP would undergo protonation. The absorption spectra suggest that anionic 2,4DC6NP, which prevails at pH > 5 would have an ortho-quinoid structure that is responsible for the absorption peak centred at 428 nm. Considering that 2,4DC6NP has been detected in the brackish lagoons of the Rhoˆne delta (southern France), where its levels are comparable to those of the parent herbicide, it is necessary to examine the possible effects of 2,4DC6NP on the species living in that environment. For this reason, the acute toxicity of the anionic form of 2,4DC6NP was assessed for the brine shrimp Artemia salina, a zooplankton species that lives both in brackish and in saline aquatic environments. The toxicity test yielded a LC 20 value of 8 AE 2 mg L À1 and a LC 50 value of 18.7 AE 0.8 mg L À1 . Such values are safely higher than the maximum detected concentration of 2,4DC6NP in the Rhoˆne delta lagoons. Further studies should be concentrated on the long-term effects of 2,4DC6NP, and in particular on its potential genotoxicity.

“…The intensive model of monocultures caused irrational and abusive use of fertilizers and the overpumping of aquatic resources, with the consequent salinization of cultivated soil, as well as the salinization of certain coastal regions (Kungolos et al [11]). Underground waters were polluted, mainly from nitrates but also from phosphoric salts, and there was an exhaustion of underground aquatic horizons in regions with hydrous cultures caused by a network of drillings (Podimata et al [12]). At the same time, two new protection issues arose: the network Natura 2000, SPA and the management of water for Greece and Thessaly.…”

Primarily, this is a discussion and review of the general European policies of management protection in the perspectives of the new CAP (Common Agriculture Policy). There are some technical proposals in Thessaly for agriculture and environmental management with the contribution of a voluntary group such as the Working Team "Natural environment" (WTNE) in Natura 2000 and SPA (Special Protection Areas) by following a strategic PLAN. The fundamental problem and concept that this article examines is if the sustainable confrontation or approach can be better improved via means of the effectiveness and the short-term "valorization / utilization" of natural resources or if solutions should be found or proposed via means of long-term "conservation" of resources. Consequently, the completion of works, as paradigm, of 'Karla' reservoir dam's plain (collectors, water reservoir, etc.) and the beginning of projects for exploitation -valorization, created a reflection in regard to the type and manner of water consumption and the more general development and the valorization of level areas in Thessaly, Greece. The choice between different sustainable management solutions, except the solely "economic effects", will be supposed to include the parameter "environment" and it approaches the question of "exploitation -valorization" of resources in a context of effectiveness and "conservation" of resources.
