Increasing precipitation accelerates soil erosion and boosts sediment loads, especially in mountain catchments. Therefore, there is significant pressure to deliver plausible assessments of these phenomena on a local scale under future climate change scenarios. Such assessments are primarily drawn from a combination of climate change projections and...

An expansion of impervious surfaces in urban areas leads to increases of nutrient loads discharged with the surface runoff to receivers. A study of a different density of urban development impact on total nitrogen (TN) and phosphorus (TP) loads from the city of Lublin (eastern Poland) with the use of the SWAT (Soil & Water Assessment Tool) model wa...

Buffer zones are considered as the most common measures aimed at reducing nutrient loadings into the aquatic environment. Assessment of their effectiveness, especially under climate change scenarios, is crucial for planning future mitigation measures and implementation of the Water Framework Directive. The goal of this study was to evaluate the pot...

Implementation of buffer zones resulted in a reduction of nutrient loads discharged from the Nurzec River. Each growth in the width of the buffer zone (from 2 to 5m, 5 to 10 m, and 10 to 20 m) resulted in an increase of yearly reduction by 60.9–76.3 and 2.8–3.5 t/y for TN and TP, respectively.

This study, conducted in 2020-2022, was designed to determine the impact of livestock grazing on habitat biodiversity and Carabidae beetles. Two research plots (a meadow and a pasture) were established on a farm in the village of Otapy, located in the agricultural catchment area of the Nurzec River in Eastern Poland. They were located next to each...

Currently, climate change is considered as an important factor affecting nutrient loads introduced through riverine systems into the Baltic Sea. Although the prospect of a large increase in pollution has long seemed very real, it still does not translate into planning of effective remedial actions. One of the factors limiting the development of suc...

Although the Carpathian Mts. area is considered as extremely prone to surface erosion which results in capacity loss of the dammed reservoirs, a lack of data to follow details of this process is perceivable. The research of the selected sediment fractions transport tracking was conducted using the capabilities of the digital platform—Macromodel DNS...

Therefore, there is significant pressure to deliver plausible assessments of these phenomena on a local scale under future climate change scenarios. Such assessments are primarily drawn from a combination of climate change projections and...

Environmental models play a key role in assessment of sediment loads released from the catchment and transported through the riverine systems under current and future conditions. To discuss the future ones the climate change scenarios are commonly incorporated into the models. Since precipitation have the most significant impact on surface runoff c...

An expansion of impervious surfaces in urban areas leads to increases of nutrient loads discharged with the surface runoff to receivers. A study of a different density of urban development impact on total nitrogen (TN) and phosphorus (TP) loads from the city of Lublin (eastern Poland) with the use of the SWAT model was performed. To distinguish bet...

Climate change affects nutrients loads that outflow to surface water, especially in terms of leaching pollutants from the catchment area. The aim of this study was the analysis of spatio-temporal pattern of loads changes influenced by climate change scenarios for a middle size catchment in the central Poland (Wełna River). The first step of the stu...

An impact of climate change on nutrient loads outflowing in the surface runoff from the sub-catchment occupied by a large agglomeration (Lublin, eastern Poland) has been studied.

Precipitation is one of the essential driving factors of natural processes influencing the structure and functioning of river catchment ecosystems. Changes in precipitation conditions have a significant impact on surface runoff and consequently the intensity of sediment transport, and its deposition especially in mountain catchments exposed to freq...

Currently, climate change is considered as an important factor affecting nutrient loads introduced through riverine systems into the Baltic Sea. Although the prospect of a large increase in pollution has long seemed very real, it still does not translate into planning of effective remedial actions. One of the factors limiting the development of suc...

Purpose The study tracks spatial and temporal distribution of sediment particles from their source to the deposition area in a dammed reservoir. This is particularly important due to the predicted future climate changes, which will increase the severity of problems with sediment transport, especially in catchments prone to erosion. Methods Analyse...

Nitrogen and phosphorus budgeting is considered to be a key tool for policy makers and stakeholders when dealing with nutrient contamination issues, however no unified method has been employed in countries affected by this eutrophication problem. The current study offers a detailed insight into the estimations of nutrient loads and their distributi...

Nitrogen and phosphorus budgeting is considered to be a useful tool for policy makers and stakeholders when dealing with nutrient contamination issues. Although a variety of budgeting approaches have been employed in countries affected by this problem, the direct comparison of possible options for the same area is quite limited. The current study o...

Excessive production of biomass, in times of intensification of agriculture and climate change, is again becoming one of the biggest environmental issues. Identification of sources and effects of this phenomenon in a river catchment in the space−time continuum has been supported by advanced environmental modules combined on a digital platform (Macr...

A database has been created as a result of the Raba River basin (Carpathian Mts., Poland) mapping/projection in the Macromodel DNS/SWAT. The sediment yield simulations (SYLD) in each of the 36 designated sub-basins have been performed, taking also into account seasonal variability. The model subsequently has been used as a reference/baseline for su...

Soil runoff and sediment transport are considered as an important vector for particle-bound contaminant transfer from source to receiving waters. Under changing climate conditions and rapid basin development, identification of sediment origins is critical for planning further action to reduce erosion effects, and further pollution to surface waters...

Agriculture, despite numerous efforts, still remains the key pressure on the aquatic environment causing an over excessive enrichment with nitrogen and phosphorus compounds. Therefore, an essential part of contemporary research and management endeavours to identify areas at risk. Presented here is a method of delimitation of such zones susceptible...

Spatial and temporal patterns of sediment contamination were examined in the Huron-Erie Corridor (HEC) of the Laurentian Great Lakes. Both the St. Clair and Detroit Rivers are designated Great Lakes Areas of Concern (AOCs) and are subject to past and prospective future sediment remediation efforts. Data generated using a system-wide probabilistic s...

Heavy metals are ubiquitous in the Great Lakes basin at a wide range of concentrations. Their historical sources are associated with geological settings of the area, while contemporary ones are attributed to anthropogenic activities of the watershed’s inhabitants. Four heavy metals in particular can be credited with the development of this area: co...

Heavy metals...

Polybrominated diphenyl ethers (PBDEs) were measured in 182 sediments from the Huron–Erie Corridor, North America. The median (5–95 percentile) Corridor ∑PBDE concentration was 1.03 ng/g dry wt (0.25–13.48 ng/g dry wt). Dry weight ∑PBDEs were elevated in U.S. waters of the Detroit River (US DR) and lowest in Canadian waters of Lake St. Clair (CA LS...

Contaminant remediation decisions often focus on sediment‐organism relationships, omitting the partitioning between sediment and water that exists across a given site. The present study highlights the importance of incorporating non‐sedimentary routes of exposure into a non‐equilibrium, steady‐state food web bioaccumulation model for predicting pol...

The continuity of sediment transport in many catchment-river-sea systems worldwide has been disturbed by anthropogenic interferences. These interferences alter the sediment balance and result either in a surplus or lack of sediment, and with mostly negative, impacts to the economy, development and infrastructure, and environment. The main issues di...

The tanning industry uses large quantities of Cr whose contribution to the contaminant burden of aquatic organisms is not yet fully understood. The present study investigated Cr bioaccumulation by indigenous chironomids in a freshwater ecosystem impacted by tannery effluents. Total Cr content in sediments and in chironomids was determined on severa...

Chromium is widely used as a tanning agent and can become a contaminant of concern in aquatic ecosystems receiving discharges from industrial or artisanal tanning activities. In a companion study, we showed that Cr discharged by tanneries was bioavailable to indigenous chironomids with accumulation via sediment ingestion likely to represent the pre...

Despite concerted efforts through the European territory, the problems of nitrogen pollution released from agricultural sources have not been resolved yet. Therefore, infringement cases are still open against a few Member States, including Poland, based on fulfilment problems of commitments regarding the Nitrate Directive. As a result of the litiga...
