Chronic exposure of sub-lethal sulphate concentrations has been found to reduce fitness in freshwater invertebrates, especially via inducing overall osmotic pressure. However, sulphate water quality guidelines have been lacking in most countries.\nSince sulphate toxicity is also context-specific and dependent on water hardness of the region, local data are needed in the effective development of regional environmental quality standards (EQS). As part of a Species Sensitivity Distribution project to derive sulphate EQS in the soft Finnish freshwaters, this study examined the chronic effect of sulphate on endangered keystone species, Margaritifera margaritifera. 7-week-old juveniles and 2-year-old mussels were exposed to different sulphate concentrations in soft water for 28 days. The 7-week-old juveniles had a lethal concentration (LC10) of 1051 mg/L and an effective concentration (EC10) of 456 mg/L, while the 2-year-old mussels had a LC10 of 683 mg/L. Chronic sulphate exposure significantly reduced relative water content in 7-week-old juveniles and inhibited mussel growth, possibly via creating high osmoregulatory stress and limiting pedal feeding as well as valve movement.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-02-02T12:17:12Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-02-02T12:17:12Z (GMT).
