Impact of River Water and Bottom Sediment Pollution on Accumulation of Metal(loid)s and Arsenic Species in the Coastal Plants Stuckenia pectinata L., Galium aparine L., and Urtica dioica L.: A Chemometric and Environmental Study

Pollution of river bottom sediments with heavy metals (HMs) has emerged as a main environmental issue related to intensive anthropopressure on the water environment. In this context, the risk of harmful effects of the HMs presence in the bottom sediments of the Warta River, the third longest river in Poland, has been assessed. The concentrations of Cr, Ni, Cu, Zn, Cd, and Pb in the river bottom sediments collected at 24 sample collection stations along the whole river length have been measured and analyzed. Moreover, in the GIS environment, a method predicting variation of HMs concentrations along the whole river length, not at particular sites, has been proposed. Analysis of the Warta River bottom sediment pollution with heavy metals in terms of the indices: the Geoaccumulation Index (Igeo), Enrichment Factor (EF), Pollution Load Index (PLI), and Metal Pollution Index (MPI), has proved that, in 2016, the pollution was heavier than in 2017. Assessment of the potential toxic effects of HMs accumulated in bottom sediments, made on the basis of Threshold Effect Concentration (TEC), Midpoint Effect Concentration (MEC), and Probable Effect Concentration (PEC) values, and the Toxic Risk Index (TRI), has shown that the ecological hazard in 2017 was much lower. Cluster analysis revealed two main groups of sample collection stations at which bottom sediments showed similar chemical properties. Changes in classification of particular sample collection stations into the two groups analyzed over a period of two subsequent years indicated that the main impact on the concentrations of HMs could have their point sources in urbanized areas and river fluvial process.

The distribution of lead, zinc, and chromium in fractions of bottom sediments in the Narew River and its tributariesThe purpose of the paper was to evaluate the distribution of lead, zinc and chromium contents in different grain fractions of bottom sediments in the Narew River and some of its tributaries. This study also aimed to determine which fractions are mostly responsible for bottom sediment pollution. The studies of the Narew and its tributaries (the Supraśl, Narewka, and Orlanka) were conducted in September 2005 in the upper Narew catchment area. The analyzed bottom sediments differed regarding grain size distribution. The studies revealed the influence of the percentage of particular grain fractions present on the accumulation of heavy metals in all bottom sediments.

Integral Assessment

Purpose. The paper deals with assessment of the ecological risks of pollution of soil at the sites where unusable plant protection chemicals are stored, and of the bottom sediments in the Ukrainian section of the Danube and in the Danube region lakes. Methodology. The applied analytical methods and synthesis of the data obtained while monitoring the studied objects, comparing data, logical generalization and analogies in combination with expert appraisals and monographic and graphical analytic studies. Findings. It was concluded that the condition of land resources of the Danube region of Ukraine is unsatisfactory. The risk of the soil ecosystem instability in the majority of the region areas is assessed as high. The monitoring data pertaining to the sites where unusable plant protection chemicals are stored indicate that the maximum permissible concentrations of certain pollutants surpass the standards by 5.032.0 times. The ecological condition of soils is assessed as medium bad while the risks are at the level varying between considerable to high. The ecological condition of bottom sediments in the Lower Danube is assessed as satisfactory, except in Kuhurlui, Yalpuh and Kytai Lakes where it is unsatisfactory. The ecological risk level in the Ukrainian section of the Danube and in the Danube region ranges from high to considerable. Originality. For the first time ever, for the Danube region of Ukraine a comprehensive assessment of the ecological risk of soil pollution, which included assessment of the risk of instability of the soil ecosystem resulting from storage of unusable plant protection chemicals, was performed. The integral assessment of the bottom sediment pollution was made for the site located between Reni town and the Danube estuary, and in Danube Lakes. Analysis of the existing methodologies for assessment of the ecological risk of soil and bottom sediment pollution enabled to develop and apply recommendations how to use indicator values describing the ecological condition with due account of the physical degradation and pollution criteria. Practical value. The obtained results can be used for the development of a strategy of effective and sustainable management of the Ukrainian Danube regions natural resources based upon the instruments and mechanisms aimed at solution of the social and economic development problems bearing in mind possible impact of the destabilizing factors.

Satisfactory State

The main goal of this study is assessing the degree of water and bottom sediment pollution in the lower Dniester by organochlorine pesticides. During the study period, the waters of the lower Dniester were in satisfactory state, an excess of EQS was registered only for the γ-isomer of HCH (Lindane), for other pollutants, an excess of EQS was not noted. The main pollutants were accumulated in bottom sediments, which is associated with the input of organic matter, bio-sedimentation. The concentration of γ-isomer HCH (lindane) in bottom sediments exceeded EQS by 5 and 20 times in spring and summer, respectively, DDT exceeded EQS by more than 4 times in summer, POPs (dieldrin and heptachlor) in summer exceeded EQS by 10.8 and 2.5 times, respectively.
