The study covered an urban river valley, strongly transformed due to the transport infrastructure development. The paper evaluates changes in spatial management of the valley section passing through the city centre that occurred during the past two centuries (long-term and short-term phenomena) as well as their effect on selected environmental components. The basic spatial analyses were carried out with the use of specialized software, cartographic materials and photographic and descriptive documentation of the studied area (archival data). The most unfavourable changes in the potential of the valley environment occurred over the past few decades. They are manifested in a considerable deterioration of landscape values as well as the quantity and quality of water resources. Relationship was identified between water quality and intensity of motor vehicle traffic near the river. Despite the progressing urbanisation of the valley, revitalisation procedures can be still carried out and attractive space in the city centre can be created. In order to demonstrate the reasonableness of the presented concept, the paper suggests that urban succession should be incorporated as a term covering time trends and accumulated transformations. It can be helpful in analysing and determining the directions of development in disputable situations.

“…As discussed previously, the sediments can be a source of contamination to the water column, predominantly Cd, Cr, Cu, Pb and Zn, particularly when they are attached to organic sediments [58]. Furthermore, Wu et al [67] reported that finer sediments, as formed by organic matter, tend to have higher metal concentrations and readily wash off into water bodies. This is of particular concern as the Geoaccumulation index (I geo ) revealed that Zn, Cu, Ti, and V are moderately contaminated in sediments and from the perspective of Pb, sediments are moderately contaminated to contaminated, particularly in the zone of the reservoir free of E. crassipes.…”

The Valsequillo reservoir is a Ramsar wetland due to its importance as a point of convergence of migratory waterfowl. It is located in Central Mexico and is currently endangered by the constant spill of municipal and industrial discharges from Puebla city. On this context, we evaluated thirteen potential toxic metals (PTMs) in water, Water hyacinth (E. crassipes) plants and sediments at this site. A combined number of 31 samples were collected from the study area. The degree/extent of metal contamination in sediments was assessed through different geochemical indexes, namely: Geoaccumulation index (Igeo), Enrichment Factor (EF) and Potential Ecological Risk Index (PERI). The ability of Water hyacinth plants residues as a phytodepurator in the Ramsar site was tested in terms of the bioaccumulation factor (BF) and the translocation factor (TF). The results concerning sediments showed that Pb, Cu and Hg pose a threat to the aquatic environment since Igeo and EF indicate sediments ranging from moderately contaminated to contaminated. Moreover, PERI pointed out Hg as the main contributor to the ecological risk in sediments, especially in the part of the reservoir covered by E. crassipes. Water hyacinth plants displayed good capacity to absorb PTMs from the water, since the content of Co, Zn, As, Ni, Cu, Pb, Ti, Cr, Ba, Mo and V in the total plant was (all values in mg/kg of dry weight) 21 ± 9, 408 ± 300, 12 ± 6, 93 ± 21, 93 ± 69, 53 ± 29, 1067 ± 643, 78 ± 55, 362 ± 39, 14 ± 0.6 and 96 ± 35, respectively. Metal content in sediments resembles to that of E. crassipes; especially in the roots, suggesting a constant deposition of plants at the bottom of the reservoir, which contributes to the eutrophication of the water. The present work encourages the need for a sustainable management of Water hyacinth plants in the Ramsar site, since they represent a plague and a natural phyto-depurator at the same time.

“…During rainfall events, these particles are washed off and transported through urban drainage systems, becoming one of the most critical sources of non-point source pollution, causing water quality impairment in receiving water bodies, and are dominant stressors in urban aquatic ecosystems. [4][5][6] Urban runoff is a critical vector of pollutants: it has been shown that they are contaminated by different chemical compounds that are transported mainly in the particulate phase and can vary considerably from one area to another. [7][8][9] Sediments act as indicators of environmental quality for stormwater because they can adsorb harmful pollutants such as nutrients, heavy metals, pesticides, and polycyclic aromatic hydrocarbons (PAHs) from the extensive and intensive impacts of anthropogenic activities.…”
