The Peninsula of Sithonia is one of many typical regions in Greece in which overexploitation of local aquifers has led to several serious problems related to quantity and quality degradation of groundwater reserves. In this paper, a management plan is presented that aims at the utilization of the so...

Three hydrographic cruises were conducted during 1997-1999 in north Aegean Sea, in order to study the dissolved oxygen (DO) and nutrient distributions in Strymonikos Gulf impacted by the riverine waters of the Strymon River. The approaches used in this paper include a preliminary estimation of the...

Lake Pamvotis is a shallow lake, located in NW Greece, which during last decades has influenced by a lot of man-made impacts such as sewage discharge, water level fluctuation, e.t.c. Water quality for physicochemical and biological parameters was monitored seasonally in five sampling-stations from...

The present study is performed with the aim to reduce the levels of polluting emissions from fuel combustion that produce acid rains and the greenhouse effect (NOx, CO2). The electric field effects on the processes of heat/mass transfer and propane combustion are studied in order to perform electric...

The malaria situation in Bulgaria during the past decade of the century was analysed and the evaluation of the risk of re-emerging of the diseases and factors determining it in the phase of maintanence of malaria eradication was carried out. The epidemiological analysis of malaria cases notified...

Air pollution is changing the ecosystems, especially in Europe. Tropospheric ozone may adversely affect tree growth, with critical levels for ozone being exceeded in many parts of Europe, especially in the Czech Republic. This research reports the information on exceedances of ozone threshold values...

Electricity generation in solid fuel fired power stations is currently the main source of flying particulates and greenhouse gases emissions. Environmental pollution is expected to deteriorate dramatically in the coming century unless pollution abatement technologies for solid fuels energy...

Fly ash (FA) and fluidized bed ash (FBA) solutions were evaluated as amendments for acid-disturbed lands, more specifically for treating acidic and metal contaminated soil. While titrating the ash materials with different volumes of acid, pH changes were monitored as a function of time and the acid...

In order to study the erodibility characteristics of some calcareous soils from Central Greece, the instability of aggregates of 2.0-4.7 mm in water was studied. Soil loss experiments were also conducted in the laboratory using a rain simulator where soil loss was measured and the soils’ attitude...

Testing was conducted with anionic diphenyloxide disulfonate (DPDS) surfactants (C12 and C16 alkyl moieties) with naphthalene in aqueous systems and phenanthrene in soil systems to investigate the influence of these surfactants on biodegradation of hydrocarbons. A potential for enhancement in the...
