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

This article presents a methodological approach for the formulation of control strategies capable of reducing atmospheric
pollution at the standards set by European legislation. The approach was implemented in the greater area of Thessaloniki and
was part of a project aiming at the compliance with air quality standards in five major cities in Greece. The methodological
approach comprises two stages: in the first stage, the availability of several measures contributing to a certain extent to
reducing atmospheric pollution indicates a combinatorial problem and favors the use of Integer Programming. More specifically,
Multiple Objective Integer Programming is used in order to generate alternative efficient combinations of the available policy
measures on the basis of two conflicting objectives: public expenditure minimization and social acceptance maximization. In
the second stage, these combinations of control measures (i.e., the control strategies) are then comparatively evaluated with
respect to a wider set of criteria, using tools from Multiple Criteria Decision Analysis, namely, the well-known PROMETHEE
method. The whole procedure is based on the active involvement of local and central authorities in order to incorporate their
concerns and preferences, as well as to secure the adoption and implementation of the resulting solution. 相似文献

Traffic is a main source of air pollutants in urban areas and consequently daily peak exposures tend to occur during commuting. Personal exposure to particulate matter (PM) was monitored while cycling and travelling by bus, car and metro along an assigned route in Lisbon (Portugal), focusing on PM2.5 and PM10 (PM with aerodynamic diameter <2.5 and 10 µm, respectively) mass concentrations and their chemical composition. In vehicles, the indoor-outdoor interplay was also evaluated. The PM2.5 mean concentrations were 28?±?5, 31?±?9, 34?±?9 and 38?±?21?µg/m3 for bus, bicycle, car and metro modes, respectively. Black carbon concentrations when travelling by car were 1.4 to 2.0 times higher than in the other transport modes due to the closer proximity to exhaust emissions. There are marked differences in PM chemical composition depending on transport mode. In particular, Fe was the most abundant component of metro PM, derived from abrasion of rail-wheel-brake interfaces. Enhanced concentrations of Zn and Cu in cars and buses were related with brake and tyre wear particles, which can penetrate into the vehicles. In the motorised transport modes, Fe, Zn, Cu, Ni and K were correlated, evidencing their common traffic-related source. On average, the highest inhaled dose of PM2.5 was observed while cycling (55 µg), and the lowest in car travels (17 µg). Cyclists inhaled higher doses of PM2.5 due to both higher inhalation rates and longer journey times, with a clear enrichment in mineral elements. The presented results evidence the importance of considering the transport mode in exposure assessment studies. 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

In the HYENA study (HYpertension and Exposure to Noise near Airports) noise annoyances due to aircraft and road traffic noise were assessed in subjects that lived in the vicinity of 6 major European airports using the 11-point ICBEN scale (International Commission on Biological Effects of Noise). A distinction was made between the annoyance during the day and during the night. Lden and Lnight were considered as indicators of noise exposure. Pooled data analyses showed clear exposure–response relationships between the noise level and the noise annoyance for both exposures. The exposure–response curves for road noise were congruent with the EU standard curves used for predicting the number of highly noise annoyed subjects in European communities. Annoyance ratings due to aircraft noise, however, were higher than predicted by the EU standard curves. The data supports other findings suggesting that the people's attitude towards aircraft noise has changed over the years, and that the EU standard curve for aircraft noise should be modified. 相似文献

In the present study, the tube well water quality and the associated health risks, emphasizing on arsenic contamination, were investigated in rural and urban samples from Tehsil Mailsi located in Punjab, Pakistan. Arsenic concentrations (μg/L) were ranged from 12 to 448.5 and which exceeded the WHO recommended limit (10 μg/L) in all cases. The calculated average daily dose (3.3 × 10?0.4 to 1.2 × 10?0.2 mg/kg day) and hazard quotient (1.1–40) reflected the potential health risk to local population due to tube well water consumption as drinking purpose. Sodium percent (Na%), sodium absorption ratio, residual sodium carbonate, Kelly’s index and magnesium absorption ratio were also determined to assess the suitability of tube well water for irrigation purpose. The resulting piper plot revealed the Na–Ca–HCO3 type water chemistry of the area and generally alkaline environment. The spatial distribution of arsenic in the tube well waters pinpoints the significant contribution of anthropogenic activities to arsenic pollution. Nevertheless, different statistical tools, including principal component analysis, hierarchical cluster analysis and correlation matrices, revealed the contribution of both natural and anthropogenic activities and alkaline type of aquifers toward the high level of arsenic contamination. 相似文献

Wildland fires are one of the more severe disturbances for natural ecosystems in the Mediterranean basin and can become a
critical factor in the process of soil erosion. A quantitative assessment of soil erosion is needed in order to form an assessment
on the extent and magnitude of post-fire soil erosion potential and to assess the effectiveness of the rehabilitation treatment.
On 21 August 2006, a large wildland fire occurred in the Kassandra Peninsula in northern Greece, which burned one fifth of
the Peninsula. After the fire, in order to protect the soil against erosion, the Forest Services applied a hillslope rehabilitation
treatment of contour-felled logs and branch piles. In this paper, we report quantitative estimation of the wildland fire and
erosion control treatment on soil erosion potential. The coupling of the Universal Soil Loss Equation and the Geographical
Information Systems was implemented and the erosion potential was found to be 2.8 t/ha/year pre-fire, 29.5 t/ha/year post-fire,
and 21.3 t/ha/year after rehabilitation treatment. The model can successfully contribute in the planning of the rehabilitation
treatment but it cannot be used in the quantification of the soil loss after the application of the erosion control measures.
The comparisons between the results of the three cases indicate the importance of the immediate erosion control measures in
order to mitigate soil loss and restore the natural environment. 相似文献
