The major part of the Polish Plain (central Europe) was shaped during the last glaciation and so far has been considered to be poor in groundwater outflows. The present study aimed to map the groundwater outflows and to analyse their water properties in the Lubuska Upland, western Polish Plain. The mapping of the groundwater outflows was supplemented by hydrochemical analyses (major ions and trace metals) of selected outflows. Altogether, approximately 600 groundwater outflows were recorded, of which 45% were springs. The outflow water discharges ranged from 0.001 to 45 L s−1. Most of them were located at the bottom of the slopes of river valleys. The water was neutral (pH 6.9 to 8.11), with electrical conductivity from 261 to 652 μS cm−1 and average temperature ~10 °C. The most common water type was dominated by bicarbonate, sulphates and calcium ions. The waters often exceeded the quality limits for total Fe and Mn2+. This study revealed that groundwater outflows are a common feature of the areas shaped by former glaciations and are most likely supplied by shallow aquifers.

Trace Metal Contamination

<p>The spatial distribution of trace metals in peri-urban soils from Kenitra city (Morocco) was investigated. A total of 10 soil samples (0-20 cm depth) were collected from the studied area. The physicochemical properties including pH, electrical conductivity and texture were determined. Contents of 6 trace metals (Cd, Cr, Cu, Ni, Zn and Pb) were measured using Atomic Absorption Spectrometry method (AAS). <strong></strong></p><p>The results showed that soils of Kenitra city have a sandy texture with a predominance of alkaline pH. The analyzed soil samples can be considered as no salt due to low electrical conductivity values. The trace metals contents revealed that soils are uncontaminated.</p>

Application of effective abatement plan to curtail particulate matter is only conceivable when the emission sources have been uniquely identified and characterized. SKC high volume gravimetric sampler Model 210-5000, serial no 20537 and respirable foam were used to capture the respirableparticle and the inhalable particle at five different locations in Obaretin between December 2008 to April 2009. The foam and the glass fibre filter were analyzed for trace metals (NI, Cr, Zn, Co, Fe, Mn, Cu, Pb and Cd) by using Atomic Absorption Spectrophotometric, (AAS). From the analysed trace metals Ni and Co were below detection limit and the trace metal Cd was moderately enriched. The total mean concentration values of the analyzed trace metals for inhalable particle (Fe: 1.70ssmg/m3 , Zn:0.0532mg/m3, Cu:0.1370mg/m3, Mn:0.034mg/m3, Cd:0.04452mg/m3, Pb: 0.15226mg/m3, Cr: 0.0070mg/m3). Trace metals in respirable particles, the total mean concentration values of the analysed trace metals are: (Fe: 1.4536mg/m3, Zn:0.0456mg/m3, Cu:0.1206mg/m3, Mn:0.1130mg/m3, Cd:0.2098mg/m3, Pb:0.13560mg/m3, Cr: 0.10000mg/m3) Ni and Co were below detection limit. The spatial distribution were insignificant (P>0.05). The values obtained in this study violated the available WHO limit and fell within the purview of OSHA limit.
