In groundwater, used for drinking water supply in the greater industrial area of Thessaloniki, in Northern Greece, concentrations of total arsenic exceeded the WHO provisional guideline value and the EU maximum contaminant level (MCL) of 10 μg/L. The concentration of total arsenic was in the range between 4–130 μg/L, whereas the median value was 36 μg/L and the average concentration 46 μg/L. Nine out of the eleven wells contained total arsenic at concentration higher than 10 μg/L and it should be stressed that 6 of them contain arsenic at concentrations between 10 (new MCL) and 50 μg/L (previous MCL). The examined groundwaters were found to contain elevated concentrations of manganese and phosphate. Arsenic had a positive correlation with the pH, indicating the possible effect of pH on arsenic mobilisation. These findings emerge the problem of contamination from arsenic, since, according to the EU directive 98/83, all drinking water sources within the European Union should have achieved compliance with the new limits by 12/2003, implying that the situation requires urgent remedial action. 相似文献

Understanding how future climate periods influence fire behaviour is important for organizing fire suppression strategy and management. The meteorological factors are the most critical parameters affecting fire behaviour in natural landscapes; hence, predicting climate change effects on fire behaviour could be an option for optimizing firefighting resource management. In this study, we assessed climate change impacts on fire behaviour parameters (rate of fire growth, rate of spread and fireline intensity) for a typical Mediterranean landscape of Greece. We applied the minimum travel time fire simulation algorithm by using the FlamMap software to characterize potential response of fire behaviour for three summer periods. The results consisted of simulated spatially explicit fire behaviour parameters of the present climate (2000) and three future summer periods of 2050, 2070 and 2100, under the A1B emissions scenario. Statistical significant differences in simulation outputs among the four examined periods were obtained by using the Tukey’s significance test. Statistical significant differences were mainly obtained for 2100 compared to the present climate due to the significant projected increase in the wind speed by the end of the century. The analysis and the conclusions of the study can be important inputs for fire suppression strategy and fire management (deployment of fire suppression resources, firefighter safety and exposure, transportation logistics) quantifying the effect that the expected future climate periods can have on fire suppression difficulty in Mediterranean landscapes. 相似文献

Detection of microcystins in Pamvotis lake water and assessment of cyanobacterial bloom toxicity 总被引:1,自引:0,他引:1

Lake Pamvotis is a shallow, eutrophic Mediterranean lake with ecological significance. This paper deals with the evaluation
of cyanobacterial toxicity in Lake Pamvotis. ELISA and HPLC revealed the presence of significant amounts of MCYST-LR. Danio rerio bioassay confirmed the toxic nature of the bloom. Cyanobacterial extracts had adverse toxic effects on development of D. rerio. Also, it was shown that cyanobacterial extracts containing environmentally detected concentrations of MCYST can cause reduced
survival rate of fish species. The results clearly indicate that cyanobacterial blooms in Lake Pamvotis may be regarded as
human and fish health hazard. Continuous monitoring of the lake is suggested, in order to prevent future possible intoxications. 相似文献

Ecological (biological and hydrochemical assessment) and hydrogeological (vulnerability and pollution risk mapping) tools
have been combined to assess the ecological quality and hydrogeological vulnerability of an agricultural river basin. In addition,
the applicability of the recently developed vulnerability assessment approach (COP method) in the particular environmental
conditions was tested by comparing its results with hydroecological assessment tools (i.e., pollution metrics). Five sampling
sites were selected and sampled for benthic macroinvertebrates and physicochemical variables during summer and spring. Overall,
sites ranged from moderate to poor ecological quality. The results illustrated that 26% of the study area was of moderate
pollution risk, while 65% was classified as of low and very low risk zones. However, the higher elevation zones where calcareous
rock formations are encountered presented moderate to high pollution risk that was accredited by the ecological quality assessment.
Pollution metrics facilitated from hydrochemical analysis indicated a significant association with groundwater vulnerability,
thus validating vulnerability and risk estimations. This study indicated that the particular groundwater pollution risk mapping
methodology and the water quality assessment indices can be well combined to provide an integrated evaluation tool at a catchment
scale. 相似文献

Toxin-producing cyanobacteria in lakes and reservoirs form a threat to humans as well as various forms of aquatic life. This
study examined the occurrence and distribution of Microcystins (MCYST) in the shallow eutrophic lake Pamvotis (Greece). MCYST
concentrations in the tissues (liver, kidneys, intestine, gonads, brain and muscle) of the fish species Carassius gibelio were also examined. Tests were performed with an enzyme-linked immunosorbent assay (ELISA). MCYST concentration in water
and in the scum of Lake Pamvotis were highest during the warm period (April–October, 2005). Phytoplankton samples were dominated
by the genera Microcystis and Anabaena during the same period. MCYST values were always below the WHO Guide level for recreational waters but much higher than the
WHO Guide level for drinking water. It was found that MCYST can accumulate in the fish tissues of C. gibelio. Even though the target organ for MCYST is the liver, in our study MCYST were found also in the rest of C. gibelio tissues in the following order: intestine> kidney> > brain>gonads> muscle. Muscle tissue contained concentrations of microcystins
that correspond to 0.096 μg/kg/day well above the recommended limit for human consumption (0.04 μg/Kg/day). 相似文献

Three representative areas (lowland, semi-mountainous, and coastal) have been selected for the collection of drinking water samples, and a total number of 28 physical, chemical, and biological parameters per water sample have been determined and analyzed. The mean values of the physical and chemical parameters were found to be within the limits mentioned in the 98/83/EEC directive. The analysis of biological parameters shows that many of the water samples are inadequate for human consumption because of the presence of bacteria. Cluster analysis (CA) first was used to classify sample sites with similar properties and results in three groups of sites; discriminant analysis (DA) was used to construct the best discriminant functions to confirm the clusters determined by CA and evaluate the spatial variations in water quality. The standard mode discriminant functions, using 17 parameters, yielded classification matrix correctly assigning 96.97% of the cases. In the stepwise mode, the DA produced a classification matrix with 96.36% correct assignments using only ten parameters (EC, Cl???, NO3 ???, HCO3 ???, CO3 ???2, Ca?+?2, Na?+?, Zn, Mn, and Pb). CA and factor analysis (FA) are used to characterize water quality and assist in water quality monitoring planning. CA proved that two major groups of similarity (six subclusters) between 17 physicochemical parameters are formed, and FA extracts six factors that account for 66.478% of the total water quality variation, when all samples’ physicochemical data set is considered. It is noteworthy that the classification scheme obtained by CA is completely confirmed by principal component analysis. 相似文献

Groundwater risk assessment at a heavily industrialised catchment and the associated impacts on a peri-urban wetland 总被引:4,自引:0,他引:4

Industrial and agricultural activities often impose significant pressures to the groundwater quality and consequently degrade wetland ecosystems that depend mostly on subsurface water flow. Groundwater vulnerability and risk mapping is a widely used approach to assess the natural protection of aquifers and the associated pollution potential from human activities. In the particular study, the relatively new Pan-European methodology (COP method) has been applied in a highly industrialized peri-urban wetland catchment, located close to Athens city, to map the intrinsic vulnerability of the aquifer and evaluate the risk potential originating from local land uses. Groundwater analysis results for various parameters, including Phenols, PCBs and nutrients, have been used to validate the vulnerability and risk estimations while a biological assessment occurred to associate the mapping results with the wetland's ecological status. The results indicated that even though the natural protection of the aquifer is relatively high due to the dominant hydrogeologic and geomorphologic conditions, the groundwater pollution risk is considerable, mainly because of the existing hazardous land uses. The water quality of the groundwater accredited these findings and the ecological status of this peri-urban wetland also indicated significant impacts from industrial effluents. 相似文献

A multi-criteria approach for the dumping of dredged material in the Thermaikos Gulf,Northern Greece

A multi-criteria approach was applied for the disposal into the sea of ~1 100 000 m3 of sediment, dredged from a coastal area in the northeastern part of the Thermaikos Gulf. This sediment (classified as muddy) is distributed vertically into two distinct Layers (A and B) with the thickness of the surficial sedimentary unit ranging from 7 to 54 cm. Its geochemistry reveals increased Cr and Ni concentrations, which may be attributed to natural enrichment through the erosion of the adjacent igneous and metamorphic rocks. In addition, a low to moderate contamination from urban-originated heavy metals, like Cu, Pb and Zn as well as from aliphatic and polycyclic hydrocarbons was identified for the upper Layer A. However, the limited proportion (5.5%) of the polluted Layer A in the total volume of the dredged material could not affect the good quality (assessed by the Sediment Quality Guidelines) of the bulk sediment. The identification of the optimum marine dumping site was based on (a) the physicochemical similarity (detected by the application of a cluster analysis) of the dredged material with the surficial deposits of potential dumping sites in the Outer Thermaikos Gulf, and (b) the consideration, based on previous studies, of various criteria related to the disposal area such as deep-water circulation, influence on living resources, impact on economical (aquaculture, fishing, navigation), recreational (fishing) and military activities. 相似文献
