TL;DR: Metal pollution in the sediments of Rijeka harbor, including anthropogenic influence during recent decades and at the present time, is studied, including metal-enrichment factors and geoaccumulation indices and spatial-distribution maps.

TL;DR: Karst rivers, such as the Krka River, with extremely low natural concentrations of trace metals are highly sensitive to the anthropogenic influence and require implementation of strict protection regimes in the entire catchments area.

TL;DR: In this paper, an experimental methodology was used based on the differential pulse anodic stripping voltammetric (DPASV) determination of labile copper species by titrating the sample using increments of copper additions uniformly distributed on the logarithmic scale.

TL;DR: In this article, three types of recent carbonate precipitates from the River Krka, Croatia, were analyzed: (1) bulk tufa from four main cascades in a 34 km long section of the river flow through the Krka National Park, (2) a laminar stromatolite-like incrustation formed in the tunnel of a hydroelectric power plant close to the lowest cascade, and (3) recent precipitates collected on artificial substrates during winter, spring and summer periods.

TL;DR: A high discrepancy between values of potentially bioavailable metal fraction estimated by different modelling programs/models raised the question about the usefulness of these data as a parameter in understanding/relating the metal uptake and their levels in aquatic organism.
