Abstract

Geochemical parameters and major ion concentrations from sediments of a freshwater lake in the town of Åtvidaberg, south-eastern, Sweden, were used to identify the geochemical processes that control the water chemistry. The lake sediments are anoxic, characterized by reduced sulphur and sulphidic minerals. The hypothesis tested is that in sulphidic-anaerobic contaminated sediments, the presence of redox potential changes creates a favourable condition for sulphide oxidation, resulting in the release of potentially toxic metals. The acid volatile sulphide (AVS) contents ranged from 5.5µmol/g to 16µmol/g of dry sediment. Comparison of total mine tailing metals (∑MTM) to simultaneously extracted metals (SEM) in sediments indicates that up to 20% of the ∑MTM are bound to the solid phase as AVS. Consequently, the AVS/SEM analysis classified all sediment samples as potentially toxic in terms of heavy metal concentrations (i.e ∑SEM/AVS > 1). Evaluation of hydrogeochemical data suggests that calcite dissolution, iron (III) oxyhydroxysulphate mineral jarosite (H-Jarosite) precipitation, hematite precipitation and siderite precipitation are the most prevailing geochemical processes that control the geochemical interactions between the water column and sediment in a mine-impacted lake. The geochemical processes were verified and quantified using a chemical equilibrium modeling program, Visual MINTEQ model version 3.1, beta. The identified geochemical processes create an environment where the characteristics of sulphate-rich waters and acidic-iron produce the geochemical conditions for acid mine drainage (AMD) and mobilization of toxic metals.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 27 August 2015.
All research outputs
#10,253,400
of 13,445,146 outputs
Outputs from Environmental Toxicology & Chemistry
#2,894
of 3,894 outputs
Outputs of similar age
#150,459
of 240,576 outputs
Outputs of similar age from Environmental Toxicology & Chemistry
#63
of 108 outputs
Altmetric has tracked 13,445,146 research outputs across all sources so far. This one is in the 20th percentile – i.e., 20% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,894 research outputs from this source. They receive a mean Attention Score of 4.5. This one is in the 19th percentile – i.e., 19% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 240,576 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 108 others from the same source and published within six weeks on either side of this one. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
