title: Effect of past century mining activities on sediment properties and toxicity to freshwater organisms in northern Sweden @sv
description: The data contain information on spatial and temporal variation in sediment properties and toxicity estimates of three lakes in close proximity to an abandoned Pb/Zn-mine. One sediment profile per lake was analyzed and the age of different sediment layers was estimated, to be able to correlate the results with known activities during the development of the mine. Number of variables: 17 Number of rows (incl. header): 76 Variable List: Site: Lake origin of the sediment core (Lake 1, Lake 2 or Lake 3) Depth: Depth of the analyzed sediment layer (cm) for each core Zn: Zinc concentration in the sediment layer (mg kg-1) Pb: Lead concentration in the sediment layer (mg kg-1) Density: Density of the sediment layer (g cm-3) LOI: Loss on ignition for each sediment layer (%) TOC: Total organic carbon for each sediment layer (%) PECQ: Predicted effect concentration quotient for each sediment layer PECQ.norm: Predicted effect concentration quotient for each sediment layer, normalized to total organic carbon content 210Pb: 210Pb activity for each sediment layer (Bq kg-1), measured at 46.5keV SD(210Pb): Standard deviation of 210Pb activity for each sediment layer (Bq kg-1), measured at 46.5keV 214Pb(295keV): 214Pb activity for each sediment layer (Bq kg-1), measured at 295keV SD(295keV): Standard deviation of 214Pb activity for each sediment layer (Bq kg-1), measured at 295keV 214Pb(351 keV): 214Pb activity for each sediment layer (Bq kg-1), measured at 351keV SD(351 keV): Standard deviation of 214Pb activity for each sediment layer (Bq kg-1), measured at 351keV 137Cs: 137Cs activity for each sediment layer (Bq kg-1), measured at 662keV SD(137Cs): Standard deviation of 137Cs activity for each sediment layer (Bq kg-1) Missing data codes: NA – not analyzed
description: Data innefattar spatiala och temporala variationer i sedimentegenskaper och estimerad toxicitet i tre sjöar nära en nedlagd Pb/Zn-gruva. En sedimentprofil per sjö analyserades och de olika sedimentlagrens ålder bestämdes, för att kunna korrelera resultaten med utvecklingen av gruvan. Antal variabler: 17 Antal rader (inkl. rubrikrad): 76 Lista på variabler: Site: Sjöidentitet på sedimentprofilen (Lake 1, Lake 2 or Lake 3) Depth: Djup på de analyserade sedimentlagren (cm) för varje profil Zn: Zinkkoncentrationen i respektive sedimentlager (mg kg-1) Pb: Blykoncentrationen i respektive sedimentlager (mg kg-1) Density: Densitet i varje sedimentlager (g cm-3) LOI: Glödförlust i varje sedimentlager (%) TOC: Totalhalt organiskt kol (%) PECQ: Predicted effect concentration quotient PECQ.norm: Predicted effect concentration quotient, normaliserad för TOC 210Pb: 210Pb aktiviteten (Bq kg-1), analyserad vid 46.5keV SD(210Pb): Standardavvikelsen för 210Pb aktiviteten (Bq kg-1) 214Pb(295keV): 214Pb aktiviteten (Bq kg-1), analyserad vid 295keV SD(295keV): Standardavvikelsen för 214Pb aktiviteten (Bq kg-1), analyserad vid 295keV 214Pb(351 keV): 214Pb aktiviteten (Bq kg-1), analyserad vid 351keV SD(351 keV): Standardavvikelsen för 214Pb aktiviteten (Bq kg-1), analyserad vid 351keV 137Cs: 137Cs aktiviteten (Bq kg-1), analyserad vid 662keV SD(137Cs): Standardavvikelsen för 137Cs aktiviteten (Bq kg-1) Missing data codes: NA – not analyzed @sv
