Abstract

The aim of the study was to compare the physical-chemical quality parameters of shallow groundwater quality in peat bogs of the Łęczna-Włodawa Lake District in the context of the occurrence of selected boreal species of plant relics: dwarfbirch (Betula humilis Schrank), downy willow (Salix lapponum L. ) and swamp willow (Salix myrtylloides L. ). Analyzes of shallow groundwater quality parameters included physical-chemical parameters: reaction (pH), electrolytic conductivity(EC), dissolved organic carbon (DOC), total nitrogen (TN), ammonium nitrogen (NH4), nitrite nitrogen (NO2), nitrate nitrogen (NO3), total phosphorus (TP), phosphate (PO4), sulfate (SO2), sodium (Na), potassium (K), calcium (Ca) and mag-nesium (Mg) by certified laboratory tests.

It was found that the natural hydrochemical specification of peat bogs is characterized by fluctuations associated with the dynamics of internal metabolism of peat ecosystems without the visible impact of anthropopressure. This is confirmed by the concentration of nutrients: TNat the study sites were within a broad range of mean values: 16.92–45.31 mg·dm–3; NH4 (0.55–0.76 mg·dm–3); NO2 (0.06–4.33 mg·dm–3); and NO3 did not exceed 0.2 mg·dm–3, and concentration of TP adopted mean values in a range of 0.22–0.42 mg·dm–3.

The studied physical-chemical factors of shallow groundwater were within the habitat preferences of the studied species, but in differentiated qualitative and quantitative ways determined optimal conditions for building the population of the studied species. Particularly values of TP lower than other obtained values in a range of: 0.08–0.32 mg·dm–3; PO4 = 0.1 mg·dm–3; TN = 2.2–21.2 mg·dm–3; NH4 = 0.1–0.46 mg·dm–3; DOC = 24.6–55.9 mg·dm–3, as well as higher than average pH values in a range of: 5.34–5.95 and concentration of Ca = 5.67–28.1 mg·dm–3 and Mg = 0.56–2.41 mg·dm–3, as well as EC = 72.1–142.3 μS·cm–1 can be treated as a condition favouring proper development of the population of dwarf birch. For Salix lapponum: a reduced level of values of nitrogen fractions (TN = 3.01–18.84 mg·dm–3; NH4 = 0.1–0.41 mg·dm–3), a reduced level of values of phosphorus fractions (TP = 0.09–0.44 mg·dm–3; PO4 = 0.1–0.44 mg·dm–3), part of ions (Ca = 4.39–19.63 mg·dm–3; Mg = 0.77–3.37 mg·dm–3), pH = 5.9–6.4, EC = 124–266 μS·cm–1 and DOC = 24.1–57.5 mg·dm–3. For the equally studied Salix myrtylloides, such conditions were met by: TP = 0.1–0.41 mg·dm–3; PO4 = 0.1–0.18 mg·dm–3, DOC = 27.5–50.9 mg·dm–3, pH = 5.3–5.94 andEC = 62.2–139.3 μS·cm–1.

Abstract

Our scientific research is based on the monitoring of ions before and after filtration of groundwaters in the water plant of Velekinca in the municipality of Gjilan, Kosovo. Sandy filters are the most commonly used industrial filters in surface – and groundwater industries. The reason is their low construction cost and high processing capacity. In our scientific re-search, sand filters used in the plant do not have perfect filtration, so we can monitor results before filtration (BF) and after filtration (AF) by determining the concentration of some ions and molecules. The following average concentrations have described: Ca2+ (BF: 83.42, AF: 83.19) mg·dm–3, Mg2+ (BF: 35.59, AF: 34.35) mg·dm–3, Cl– (BF: 28.018, AF: 28.73) mg·dm–3, SO42– (BF: 42.76, AF: 44.46) mg·dm–3, HCO3– (BF: 410.9, AF: 404.81) mg·dm–3, A-HCl (BF: 6.73, AF: 6.63) ml-HCl, GH (BF: 19.94, AF: 19.62) °dH, CS (BF: 18.87, AF: 18.5) °dH and NO2– (BF: 0.0033, AF: 0.0022) mg·dm–3. Be-ing scientific researchers in the field of water treatment technology, we have concluded that ions create an affinity for sand particles. They attach to each other by creating an ion-sand particle physical chain. According to our scientific research, sand filters are difficult to guarantee a high quality of water processing.

Abstract

The objective of this study is to assess the physical-chemical quality of urban wastewater from the city of Boumerdès, in northern Algeria with regard to the threshold values for irrigation or their discharge in aquatic ecosystems. Five sampling points were carried out of the study area in April 2017. The results obtained of physical- chemical parameters indicating pollution show that the water course is exposed to pollution mainly of organic origin. It’s expressed by a high maximum value according to Algerian and World Health Organisation standards: chemical oxygen demand ( COD 886 mg O ₂∙dm ^–3), biochemical oxygen demand ( BOD ₅ 490 mg O2∙dm ^–3), nitrate (NO ₃ ^– 73.09 mg∙dm ^–3), nitrite (NO ₂ ^–6 mg∙dm ^–3), ammonium (NH ₄ ⁺ 23 mg∙dm ^–3) and phosphates (PO ₄ ^3– 7.3 mg∙dm ^–3). The COD to BOD ₅ rate of 1.8, show that the effluents must be treated before being discharged into the receiving environment. However, it is lower than 2, which makes them easily biodegradable and can be treated by a biological system such as a natural lagoon. It shows also a diversified origin of the pollution. It is predominantly domestic origin, it could have an adverse effect on public health, presenting a risk of environmental eutrophication, contamination of soil and water resources. The physical-chemical characterisation of the urban wastewater shows that they are quite loaded and present a pollution in nitrogenous compounds, a treatment is requested before the direct discharge to the receiving environment or their reuse in the irrigation.
