Data för: Evaluation of Standardised (ISO) Leaching Tests for Assessing Leaching and Solid–Solution Partitioning of Perfluoroalkyl Substances (PFAS) in Soils
No full textThe dataset contains chemical analysis results of PFAS concentrations in soils and leacha-tes (eluats) from leaching tests performed on the soils studied. The data set is the raw data derived for the study by Kleja et al (2025). The set contains results for one field-contaminated soil and three spiked soils (12 PFAS contaminants) aged for 5 months, all of which were examined using batch tests in accordance with ISO 21268-2: 2019 with either deionised water or 1 mM CaCl2 as leachant (liquid-to-solid phase ratio (L/S) of 10) and percolation tests according to ISO 21268-3:2019 with 1 mM CaCl2 as leaching fluid. The solubility of PFAS as a function of tumbling time (1, 8, 24, 48, 96 and 240 hours) with 1 mM CaCl2 as leachant in the batch test (ISO 21268-2:2019) was also investigated. Leach-ate (eluate) produced using ISO 21268-3:2019 was analysed for PFAS, pH and conductivi-ty, while leachate from ISO 21268-2:2019 was also analysed for DOC, Al, Ca, Fe, K, Mg, Mn, Na, Cl and SO4.

Environments 2025, 12, 179. https://doi.org/10.3390/environments12060179Datasetet innehåller kemiska analysresultat av PFAS-koncentrationer i jordar och lakvat-ten (eluat) från laktester utförda på de studerade jordarna. Datasetet utgör rådata till studien av Kleja et al (2025). Setet innehåller resultat för en fältkontaminerad jord och tre spikade jordar (12 PFAS föroreningar) åldrade i 5 månader som alla undersöktes med batch test enligt ISO 21268-2:2019 med antingen avjonat vatten eller 1 mM CaCl2 som lakvätska (vätska-till-fast fas-förhållande (L/S) på 10) och perkolationstest enligt ISO 21268-3:2019 med 1 mM CaCl2 som lakvätska. Lösligheten hos PFAS som en funktion av skaktid (1, 8, 24, 48, 96 och 240 timmar) med 1 mM CaCl2 som lakvätska i batchtestet (ISO 21268-2:2019) undersöktes också. Lakvatten framtagna med ISO 21268-3:2019 analysera-des för pH och konduktivitet, medan lakvatten från ISO 21268-2:2019 också analyserades för DOC, Al, Ca, Fe, K, Mg, Mn, Na, Cl och SO4.

Nationell Riktad Skogsskadeinventering (NRS) - Barkborreskador på gran i Västernorrlands län och östra Jämtland 2016
No full textInventories of forest damage are carried out within the Swedish University of Agricultural Sciences (SLU) Forests programme. An annual monitoring of the most important sources of forest damage is carried out by the Swedish National Forest inventory (NFI). Although the Swedish NFI is an objective and uniform inventory of forest damage in Swedish forests at national and regional scales, less common or less widespread occurrences of forests pests and pathogens are difficult to survey solely through large-scale monitoring programmes. There is a need for complementary inventories to facilitate timely delivery of relevant information.
Thus Target-tailored forest damage inventories (TFDI) aiming at providing data for operational decisions making at local level, and linked to specific damage events were introduced. TFDI’s are developed to give rapid response to requested information of specific damage outbreaks. The TFDIs are carried out in limited and concentrated samples, with flexible but robust methods and design. The data collected in the TFDI shall also be of such quality that it can be useful in research.
During 2016 TFDI carried out a sample inventory of the volume Norway spruce (Picea abies) damage by bark beetles, Four-eyed spruce bark beetle (Polygrapus poligraphus) and/or European spruce bark beetle (Ips typographus) in older spruce forest in the county of Västernorrland and in eastern Jämtland (township of Bräcke, Ragunda and Östersund). The inventory in 2016, just like in 2014 and 2015, also includes Jämtland, compare to the previous years, as a follow-up to the severe winter storms in 2013, which felled a large amount of forest. The inventory included both standing and wind-felled trees. The purpose of the inventory was to estimate the volume Norway spruce damage by the given bark beetles, but also to highlight geographical distribution and the appearance of the damage in different forest sites. The results from the inventory should be available for decisions making basis in forestry managements.
The inventory was stratified by an objective sample of all the National Forest Inventory permanent sample plots in the county of Västernorrland and eastern Jämtland. Included plots within the sample was all older thinning forest and final felling mature forest consisting of at least 7/10 proportion of spruce. The radii of sample plots use for the damage inventory was 25 m. Diameter at breast height was measured on damage trees and wind-felled trees. Diameter on stump from cut trees with fresh damage was measured. Furthermore species of bark beetle and age of damage was recorded. The inventory was carried out in the same way as in 2011, 2012, 2013, 2014 and 2015. Measurements of wind-felled trees were included from 2013 onwards and comprises both wind-felled trees newly infested (season 0) with bark beetles and fresh wind-felled trees not infested with bark beetle. In 2016, the variable “including stump” is included, which explains if the windfall is a whole tree. This is also explained by the variable ”full length” which also is included in previous years. The dataset consist at plot level of 147 rows with 23 column, at tree level of 466 rows with 12 columns and at wind-felled tree level of 72 rows with 13 columns.
Some assessed and used variables:
At sample plot level:
Plot area measured
The proportion of spruce at the sample plot
Maturity class
At tree level:
Is the tree dead or alive?
Position of tree – standing, stump
Diameter at breast height
Which species of bark beetle has attacked the tree?
Which season did the damage occur?
Tree volume
At wind-felled tree level:
Diameter at breast height
Is the tree infested by bark beetle?
Which species of bark beetle has attacked the tree?
Which season did the tree fell?
Tree volume
See the document "Data_description" for more detailed information. As additional documentation, field instructions for the inventories are also provided, both for the specific inventory and for the National Forest Inventory (NFI). An English version of the National Forest Inventory field instruction is available for year 2021 only, which is why this is included here.Med hjälp av ett flexibelt inventeringskoncept inriktat på skogsskador kan Sveriges Lantbruksuniversitet (SLU) inom miljöanalysprogrammet Skog följa upp och presentera information om olika slags skogsskador. En årlig uppföljning av stora skadeutbrott i våra svenska skogar sker via Riksskogstaxeringens (RT) objektiva inventeringar. Men trots att vi här får en kontinuerlig uppföljning av de viktigaste skadesymptomen saknas ofta möjligheten att på ett lämpligt sätt följa upp regionala skadeutbrott.
Med fler förväntade skadeutbrott i klimatförändringarnas spår finns ett stigande behov av regional information med god precision. För att effektivisera övervakningen av skogsskador har Nationell Riktad Skogsskadeinventering (NRS) introducerats med skräddarsydda inventeringar riktade mot enskilda skadegörares utbrott. NRS ska kunna leverera underlag om en skadas status och omfattning, så att specifika operativa beslut kan fattas. Därför kan inriktningen av inventeringen variera beroende på vilka skador som för tillfället är mest relevanta och för vilka skador det finns uttalade behov av information. Inventeringen ska vara åtgärdsorienterad och snabbt kunna leverera resultat. Data som samlas in i NRS ska också vara av sådan kvalitet att de kan vara användbara inom forskningen.
Under 2016 har inom NRS genomförts en stickprovsinventering utav barkborreangrepp av dubbelögad bastborre (Polygrapus poligraphus) och/eller granbarkborre (Ips typographus) i äldre granskog i Västernorrlands län och östra jämtlands län (Bräcke, Ragunda and Östersund kommun). Inventeringen 2016 omfattar precis som 2014 och 2015 även Jämtland, jämfört med tidigare års inventeringar, som en uppföljning av de kraftiga stormarna under december 2013, vilka fällde en stor mängd skog. Inventeringen omfattar både stående angripna träd och vindfällen. Syftet med inventeringen var att skatta volym angripen gran, men också att belysa den geografiska fördelningen samt skadornas uppträdande på olika typer av mark och i olika typer av föryngringar. Resultaten från inventeringen ska kunna fungera som beslutsunderlag till möjliga skötselåtgärder.
Inventeringen stratifierades genom ett objektivt urval av Riksskogstaxeringens alla permanenta provytor i Västernorrlands län. I urvalet ingick, alla ytor i äldre gallrings eller slutavverkningsmogen granskog (≥ 7/10 gran). Inventeringen utfördes på den del av en cirkelyta med 25 m radie, vars yta ingick i det beskrivna beståndet. Andra delar av cirkelytan ingick inte i inventeringen. På angripna stående träd och vindfällda träd har brösthöjdsdiameter uppmätts. På stubbar efter avverkade träd med färska angrepp har stubbdiameter uppmätts. Förutom diameter har också barkborreart och ålder på angreppen angetts. Inventeringen har genomförts på samma sätt som under 2011, 2012, 2013, 2014 och 2015. Inmätning av vindfällen inkluderades från och med 2013 och omfattar både vindfällen med färska angrepp (säsong 0) samt färska vindfällen utan angrepp av barkborrar. Under 2016 finns variabeln ”rotdel” med som förklarar om vindfället är ett helt träd. Detta framgår även under variabeln ”full längd” som finns med även tidigare år. Totalt inventerades 147 provytor. Antalet inmätta angripna träd var 466 och vindfällen var 72. Datafilerna innehåller på provytenivå 147 rader med 23 kolumner, på trädnivå 466 rader med 12 kolumner samt för vindfällen 72 rader med 13 kolumner.
Viktigaste inventerade bedömda variabler och beräknade variabler:
På ytnivå:
Inventerad areal

Kommunal partiorganisation 1985
No full textThe study was conducted in connection with the 1985 general election and was based on a survey directed at local party organizations, specifically targeting the organizations’ chairpersons and campaign managers. The primary focus of the survey was on the parties’ local organization, activities, and political positions. Several questions were designed as a direct follow-up to the local democracy research group’s corresponding survey conducted during the 1979 election. In addition, the questionnaire included specific sections concerning election campaigns, campaign strategies, and perceived electoral outcomes.Studien genomfördes i anslutning till riksdagsvalet 1985 och baserades på en enkätundersökning riktad till kommunala partiorganisationer, specifikt till organisationernas ordförande och valledare. Undersökningen fokuserade främst på partiernas lokala organisation, verksamhet och politiska ställningstaganden. En del av frågorna utgjorde en direkt uppföljning av den kommunaldemokratiska forskningsgruppens motsvarande studie i samband med valet 1979. Utöver detta innehöll enkäten särskilda avsnitt med fokus på valkampanjer, valstrategier och upplevda valresultat

För att effektivisera övervakningen av skogsskador har Nationell Riktad Skogsskadeinventering (NRS) introducerats med skräddarsydda inventeringar riktade mot enskilda skadegörares utbrott. NRS ska kunna leverera underlag om en skadas status och omfattning, så att specifika operativa beslut kan fattas. Därför kan inriktningen av inventeringen variera beroende på vilka skador som för tillfället är mest relevanta och för vilka skador det finns uttalade behov av information. Inventeringen ska vara åtgärdsorienterad och snabbt kunna leverera resultat. Data som samlas in i NRS ska också vara av sådan kvalitet att de kan vara användbara inom forskningen.
Under 2015 har inom NRS genomförts en stickprovsinventering utav barkborreangrepp av dubbelögad bastborre (Polygrapus poligraphus) och/eller granbarkborre (Ips typographus) i äldre granskog i Västernorrlands län och östra Jämtlands län (Bräcke, Ragunda and Östersund kommun). Inventeringen 2015 omfattar precis som 2014 även Jämtland, jämfört med tidigare års inventeringar, som en uppföljning av de kraftiga stormarna under december 2013, vilka fällde en stor mängd skog. Inventeringen omfattade både stående angripna träd och vindfällen. Syftet med inventeringen var att skatta volym angripen gran, men också att belysa den geografiska fördelningen samt skadornas uppträdande på olika typer av mark och i olika typer av föryngringar. Resultaten från inventeringen ska kunna fungera som beslutsunderlag till möjliga skötselåtgärder.
Inventeringen stratifierades genom ett objektivt urval av Riksskogstaxeringens alla permanenta provytor i Västernorrlands län. I urvalet ingick, alla ytor i äldre gallrings eller slutavverkningsmogen granskog (≥ 7/10 gran). Inventeringen utfördes på den del av en cirkelyta med 25 m radie, vars yta ingick i det beskrivna beståndet. Andra delar av cirkelytan ingick inte i inventeringen. På angripna stående träd och vindfällda träd har brösthöjdsdiameter uppmätts. På stubbar efter avverkade träd med färska angrepp har stubbdiameter uppmätts. Förutom diameter har också barkborreart och ålder på angreppen angetts. Höjd och volym är enbart skattad för träd angripna under innevarande (0) säsong. Inventeringen har genomförts på likartat sätt som under 2011, 2012, 2013 och 2014. Inmätning av vindfällen inkluderades från och med 2013 och omfattar både vindfällen med färska angrepp (säsong 0) samt färska vindfällen utan angrepp av barkborrar. Totalt inventerades 153 provytor. Antalet inmätta angripna träd var 40 och vindfällen var 162. Datafilerna innehåller på provytenivå 153 rader med 23 kolumner, på trädnivå 40 rader med 12 kolumner samt för vindfällen 162 rader med 12 kolumner.

Vilken granbarkborreart har angripit trädet
Vilken säsong är angreppen gjorda
Trädets volym
På vindfälle nivå:
Brösthöjdsdiameter
Är vindfället angripet av barkborre?

Se dokumentet "Databeskrivning" för mer detaljerad information. Som ytterligare dokumentation tillhandahålls också fältinstruktioner för inventeringarna, både för den specifika inventeringen och för Riksskogstaxeringen. En engelsk version av Riksskogstaxeringens fältinstruktion finns endast för år 2021 vilket är anledningen till att den är inkluderad här
Domed oblong brooches of Vendel Period Scandinavia
No full textThe study's aim was to investigate oblong brooches of Vendel Period Scandinavia, i.e. Ørsnes types N & O and similar brooches, including transitional types surviving into the Early Viking Period. A database of 593 brooches from all of Scandinavia was studied and interpreted by typology, chronology, function, social significance, technological characteristics, production sites, interregional variation and ideological connotations. Unique brooches are described and discussed. Brooches from Uppåkra are also described and discussed, against the background of the new results. The study then puts forward two new seriation chronologies for Vendel Period female graves on Bornholm and in Sweden.
Purpose:
The aim of the study is to offer new perspectives on domed oblong brooches of Vendel period Scandinavia and transitional types which survived into the earliest Viking period. The new perspectives are based on a larger and more recent material base and a widened geographic scope, covering all of Scandinavia.
The dataset consists of a table with information on domed oblong brooches from Vendel period and early Viking period Scandinavia. The data includes inventory numbers, provenance, measurements, type and context. The data is downloadable in -xls and .csv format. The download package also contains the study article and a codebook.
The dataset consists of 1267 photographs of the domed oblong brooches studied by the author. Formats include JPEG and TIFF.Studien berör välvda ovala spännbucklor i vendeltidens Skandinavien, d.v.s. Ørsnes typer N & O och liknande spännbucklor, inklusive övergångstyper som levde kvar in i den tidiga vikingatiden. En databas på 593 föremål från hela Skandinavien används i studien. Föremålen studeras och tolkas med avseende på typologi, kronologi, funktion, social betydelse, tekniska egenskaper, produktionsplatser, interregional variation och ideologiska konnotationer. Avvikande spännbucklor samt sådana från Uppåkra beskrivs och diskuteras separat. Studien lägger även fram två nya relativa kronologier för vendeltida kvinnogravar på Bornholm och i Sverige.
Syfte:
Studiens syfte är att erbjuda nya perspektiv på välvda ovala spännbucklor i vendeltidens Skandinavien, och övergångstyper som levde kvar in i den tidiga vikingatiden. De nya perspektiven baseras på ett stort nytt dataunderlag samt har en bredare geografisk omfattning som täcker hela Norden.
Datasetet består av en tabell med information om välvda ovala spännbucklor från vendeltiden och vikingatiden. Uppgifterna innefattar bland annat inventarienummer, geografiskt läge, mätdata, typ och kontext. Data går att ladda ned i XLS- och CSV-format. Nedladdningspaketet innehåller också studieartikeln och en kodbok.
