The Impact

Research results define basis for specific monitoring programs of gro-undwater quality in wetland eco-systems in Serbia and Croatia. The main pur-pose of the research was to determine the impact of nonpoint diffuse source pollution on the groundwater quality, as well as seasonal variations on the con-centration levels of selected physico-chemical parameters. Statistical analyses, PCA, HCA, ANOVA and t-test, encompass 18 monitored parameters in ground-water. Statistical data indicated that protected area in Serbia has a significantly higher load of pollution from agricultural activities compared to Wetlands Tompojevci. The highest load in groundwater was detected from total nitrogen, ammonia and nitrogen anions, indicating contamination of groundwater by nitrogen-based fertilizers. The results obtained within the two-year seasonal monitoring program, from 2018 to 2020, are highly essential for achieving a comprehensive database that could be used as platform for high-quality groundwater management in selected protected areas with the aim of minimizing environmental pollution.

Groundwater is generally used for various purposes, particularly domestic and industrial purposes in all over the world. Fresh water from groundwater sources is high in the recent years and the groundwater is polluted high because of rapid population and industrial growth. It is very difficult to restore the contaminated groundwater by various pollutants.  Hence, it is important to analyse physico-chemical parameters of groundwater for its need for various sectors. Therefore, the present study was under taken to define the quality of groundwater with the help of WQI. The ground water samples were collected from 20 different places around Ambattur Industrial Estate in Chennai city. The groundwater quality assessment showed that the water quality of bore wells around Ambattur Industrial Estate is poor for drinking purpose as per WQI for BIS acceptable limit.  WQI observed from those selected 20 groundwater bore wells are ranging from 63.30 to 219.63.   The analysis reveals that the groundwater from the Ambattur Industrial Estate needs pre-treatment before it is being used for various purposes.

The Impact

The study was conducted to assess the impacts of trout farming on water quality using macro invertebrates as bio-indicators. Two trout farms were selected for the study, viz., Gandaki Trout Farm (GTF) in Kaski district and Fall & Trout Fish Farm (FTF) in Nuwakot district. Reference and impacted sites were selected in each trout farms from where macro invertebrates were collected and physico-chemical parameters were measured. Sorensen’s Index and Multiple Site Similarity Index were calculated to compare the macro-invertebrate assemblages between the impact and the reference sites. Water quality classes were also calculated using macro invertebrate-based tool, NEPBIOS/ASPT scores. Altogether 24 families of macro invertebrates were observed at GTF and 12 families at FTF. The Sorensen’s Similarity Index was greater than 0.5 between reference and impacted sites at GTF; whereas it was only 0.28 at FTF indicating comparatively low level of similarity. In addition, Multiple Site Similarity Index (0.64) at GTF also indicated high similarity between the macro invertebrate assemblages. Reference sites showed higher scores with higher diversity of macro invertebrates. Both farms had suitable water quality for trout (dissolved oxygen and temperature) and most of the physico-chemical parameters did not show significant differences except pH and turbidity at GTF probably due to small scale operation and production. Journal of Institute of Science and TechnologyVolume 22, Issue 2, January 2018, Page: 175-182

The thickness of non-saturated zone and physico-chemical conditions are important parameters to assess the impact of infiltration ponds on water resources with respect to heavy metals transfer. As changes in physico-chemical parameters of solutions have a strong impact on the mobility of colloidal phases in sediments and soils, the colloidal facilitated transfer of heavy metals has to be investigated. Therefore, this study focuses on the characterization of runoff, surface and interstitial waters in a retention/infiltration pond collecting runoff waters of a bridge near Nantes. Physico-chemical parameters and chemical analyses were performed on the waters during about one year. The separation of dissolved and colloidal fractions was carried out by filtration and ultrafiltration for one sample of surface and interstitial waters. Until now, the runoff waters were only filtered at 0.45 μm. The comparison of physico-chemical data shows that the minor variations of runoff water parameters are mitigated in basin and in soils but strong variations impact the composition of interstitial waters. High concentrations of zinc, copper and still of lead are measured in runoff. Lead and cadmium seem to be associated to colloidal and particulate fractions while zinc, copper, nickel and chromium are distributed in all fractions.

The Impact

The influence of different fermentation conditions and cabbage hybrids and variety, ?Tenacity?, ?Bravo? and ?Futoski?, on physico-chemical properties of cabbage heads was studied in this research. Experiment was set up in industrial conditions. Samples 1T, 4B and 7F were obtained by spontaneous fermentation with 3.3% NaCl solution, samples 2T, 5B and 8F were obtained with brine from previous cabbage fermentation and samples 3T, 6B and 9F were treated with 100 mL of lactic-acid starter culture onto 3.3% NaCl solution. Previous cabbage fermentation was done with 3.3% of salt solution and final percentage of salt in brine used for investigation was 2.57%. Cabbage samples were taken after 0, 3, 6, 12, 24 days and at the end of fermentation process (44th day for one group of samples and 55th day for the other) in order to determine total color and texture changes. Temperature and pH value were analyzed during the fermentation process, while water activity (aw) and total sugars content were analyzed for raw cabbage samples and on the last fermentation day. 44th day was determined as the end of fermentation for six samples, and 55th day for three samples, by measuring remaining sugar content. Considering into account all obtained results and fermentation conditions, sample 9F shown the best properties at the last fermentation day in terms of investigated physico-chemical parameters. aw value, shear force, total color change, pH value and total sugar content of this sample on the last fermentation day were 0.958, 14672 g, 8.46, 3.45 and 0.92%, respectively.

This scientific paper enables us to present the bacteriological, physico-chemical parameters and heavy metals present in the soil of Elbasan city. Through this study we have obtained significant data that give us the opportunity to judge about soil impurity of Elbasan city, allowing us to present a current assessment of soil pollution. The pollution of the land of a historical-cultural city like Elbasan takes on a considerable importance in terms of the impact on the health of citizens, based mainly on the cultivation of agricultural crops in the study area. In view of this goal, during the September-October 2020 period, some soil samples were taken and analyzed in the laboratory, where the area predetermined by us for samples taking consists of the geographical space where the heavy industries of Elbasan city operate. All bacteriological, physico-chemical parameters and heavy metals part of the soil of Elbasan are presented for the first time in this paper. As a result of the results obtained where we encounter a significant soil pollution of Elbasani town we think that is attributed to the fact that Elbasan has always been considered as one of the most polluted cities in Albania in recent years. Finally, we can say that land pollution comes as a result of productive activities of light and heavy industries, which operate without implementing the rules of environmental protection in Albania but also from human activity mainly in agriculture, where we mention the use without criteria of pesticides and chemical fertilizers.

The objective of this work is to evaluate the physico-chemical quality of the groundwater of the Merdja plain and to determine the sources of mineralization. This quality is influenced by several environmental and anthropogenic factors such as geological context, climate, precipitation and interaction between groundwater and aquifers and human activities.  A Principal Component Analysis (PCA) on samples taken from several wells spread over the entire Tebessa plain (Merdja) allowed us to detect two axes that explain 73.4% of the information. The first axis describes the variables related to mineralisation and the second one describes those related to agricultural activity. Multidimensional Positioning (MDS) confirmed the interaction of physico-chemical parameters between them and their influence on groundwater quality by highlighting three groups of wells according to their physico-chemical characteristics, particularly those containing high concentrations of nitrates. This contamination is mainly the result of spreading the fertilisers and wastes that are dumped into the plain without treatment. Salinization is the result of long-term interactions between groundwater and geological formations.

AbstractOligochaeta samples were collected from seven lakes (2 natural and 5 non-natural) of Ceyhan River basin during the summer and autumn seasons of 2014. The Ceyhan River basin is located in the south-eastern Anatolia region in Turkey. Lakes Gölbaşı and Azaplı are located in a protected area. Some physico-chemical parameters of surface water were measured in situ. Sampling for oligochaetes was conducted by using both hand-nets and an Ekman Birge grab sampler, with samples obtained from different depths. Oligochaetes represented the dominant group of the total benthic macroinvertebrates in samples, with the exception of samples collected from Ayvalı Dam lake. A total of 11,293 oligochaete specimens were sorted from samples collected from these lakes, from which 14 species belonging to 2 subfamilies (Naidinae and Tubificinae) were identified.
