“…The minimum Ca levels that we obtained were also lower than those reported by other, already mentioned authors who gave the values of 5,700 and 7,490 mg·kg -1 , respectively. An opposite situation is observed in the case of Mg concentration in R. japonica leaves when compared with the results obtained by other researchers [5,13,48] [50] and in Japan [51]. In those cases, Japanese knotweed populations from areas with soils contaminated with Cu (3,000 mg·kg -1 of dry mass), Zn (10,000 mg·kg -1 ), and Cd (100 mg·kg -1 ) were analyzed.…”

“…This includes having an impact on the biogeochemical cycles of N and other elements [5][6][7][8], on the quantity and quality of soil organic matter [9], and on soil pH [10]. Changes to the chemical properties of soil due to the influence of vegetation have been observed in many different ecosystems [5,[11][12][13][14][15], and recently special attention has been focused on the role of alien species in soil nutrient enrichment [16,17]. Different plant species, including alien ones, have been shown to directly impact the modification of biotic soil environments [7,10,18].…”

Abstract:The study was conducted on six sites that are dominated by Japanese knotweed (Reynoutria japonica) and that vary in the level of industrialization and habitat transformation by humans. The aim of the research was to investigate the chemical-physical features of soil under a closed and dense canopy of R. japonica, the chemical composition of the R. japonica leaves, and to compare the content of certain elements in the soil-plant-soil system. The soil organic carbon (C org ) content varied from 1.38±0.004% to 8.2±0.047% and the maximum in leaves was 49.11±0.090%. The lowest levels of total nitrogen (N tot ) in soil were recorded on the heavily disturbed sites (till 0.227±0.021%). Soil pH varied greatly, ranging from acidic (pH=4.0) to neutral (pH=7.7). Heavy metal content differed significantly among the study sites. At all of the sites, both in the case of soil and plant leaves, Zn was a dominant element and its concentration ranged from 41.5 to 501.2 mg·kg -1 in soils and from 38.6 to 541.7 mg·kg -1 in leaves. ) were observed on the site that had been influenced by agricultural practices. The results obtained showed that R. japonica is able to accumulate high levels of heavy metals.

Abstract:The publication is a synthetic review of many years of research on the possibility of using water plants (macrophytes) to assess pollution of surface waters and the possibility of using the biomass in phytoremediation processes. The results of the research of kinetics and equilibria of heavy metals sorption and desorption conditions were presented in order to repeatedly use the biomass, as well as the research on the influence of abiotic factors on sorption processes. Defence mechanisms of macrophytes, which enable them to vegetate in considerably polluted waters, have been discussed. The results presented herein and carried out in many countries demonstrate that macrophytes can be successfully used in the biomonitoring of water environments and phytoremediation of waters and sewage; however, validation of these procedures requires more detailed research of the mechanisms, which accompany them.

“…The total number of species should be adequate for monitoring based on macrophytes, as indicated by a previous study which found a similar number of macrophyte taxa (48) and species (8)(9)(10)(11)(12) [36], and was able to determine stream type in lowland mid-sized streams.…”

“…Macrophytes in particular are recognized as sensitive indicators of eutrophication because they react to various forms of nitrogen and phosphorus concentrations in the water [1][2][3][4][5][6][7][8]. Several studies have revealed relationships between macrophyte distribution and acidification [2,8,9] salinization [10], alkalinity [2,8], conductivity [2,5,11], heavy metal pollution [12] and hydromorphological degradation [3,13].…”

Drivers of macrophyte development in rivers in an agricultural area: indicative species reactions

The ecological drivers of macrophyte development in a lowland agricultural area were tested based on a 2008 survey on the Wkra River catchment. Our survey was carried out in the rivers of an agricultural area with relatively high concentrations of both nitrates and phosphates in the water. By using the Polish macrophyte method, we were able to calculate several botanical metrics. Canonical ordination analyses used to relate biological data to environmental variables such as physical and chemical parameters of water, surface water velocity or river width, were carried out using CANOCO for Windows. Redundancy analysis (RDA) showed that pH and alkalinity were the parameters best correlated with the distribution of macrophytes and values of macrophyte indices. The recorded values of the Macrophyte Index for River in the Wkra River and its tributaries reflected their good and moderate ecological status (the Water Framework Directive scale). Despite the fact that nutrient concentrations in the water were relatively high and that most of the sites represented eutrophic conditions, the results of this survey showed that non-nutrient parameters may play an important role in explaining aquatic plant occurrence in rivers that have been subjected to eutrophication.
