Inland freshwaters are of great importance for human health and activities, but major stressors such as nutrient pollution, deforestation, urbanization compromising their status. Water quality degradation freshwater ecosystem preservation current issues worldwide requiring frequent efficient monitoring protocols. The increasing need large amounts data to comply with national international regul...

Available experimental data describing Al(III) and Fe(III) binding by fulvic and humic acids can be explained approximately by Humic Ion Binding Model VI. The model is based on conventional equilibrium reactions, involving protons, metal aquo ions and their first hydrolysis products, and binding sites ranging from abundant ones of low affinity, to rare ones of high affinity, common to all metal...

Endosulfan is an insecticide-acaricide used in South Florida and is one of the remaining organochlorine insecticides registered under the Federal Insecticide Fungicide and Rodenticide Act by the U.S.EPA. The technical grade material consists of two isomers (alpha-, beta-) and the main environmental metabolite in water, sediment and tissue is endosulfan sulfate through oxidation. A comprehensive...

Phenology changes are increasingly recognized as a common response of species to ongoing global change. can be influenced by environmental cues that impact the initiation or duration life history events well intrinsic organismal traits may affect how different respond such cues. Despite importance phenology for biodiversity conservation demonstrated terrestrial and marine research, freshwater i...

Abstract Human proximity to water and its dynamics are important understanding the socio-hydrological dilemma between using floodplains avoiding flood risk. However, previous studies have not distinguished of built-up land in (BLF) outside (BLOF). This article provides a new spatiotemporal perspective BLF proximities for changing risk China. The results show that China’s BLFs had an average 5.4...

Abstract High environmental microplastic pollution, and its largely unquantified impacts on organisms, are driving studies to assess their potential entry pathways into freshwaters. Recreational angling, where many anglers release manufactured baits freshwater ecosystems, is a widespread activity with important socio-economic implications in Europe. It also represents pathway freshwaters that h...

An evaluation of flow-injection analysis with chemiluminescence detection (FIA-CL) to quantify Fe(2+) ((aq)) in freshwaters was performed. Iron-coordinating and/or iron-reducing compounds, dissolved organic matter (DOM), and samples from two natural water systems were used to amend standard solutions of Fe(2+) ((aq)). Slopes of the response curves from ferrous iron standards (1 - 100 nM) were c...
