Cirkulärt omhändertagande av solcellspaneler och vindturbinblad för vindkraftverk
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I regleringsbrevet för 2023 fick Energimyndigheten i uppdrag av regeringen att utreda hur solcellspaneler och vindturbinblad till vindkraftverk i högre utsträckning ska kunna tas om hand på ett giftfritt och cirkulärt sätt i enlighet med avfallshierarkin. Redovisningen av detta regeringsuppdrag, rapporten Från avfall till resurs – Förslag för en mer cirkulär hantering av solcellspaneler och vindturbinblad, ER 2024:11, baseras på denna underlagsrapport som har tagits fram av forskningsinstitutet RISE på uppdrag av Energimyndigheten. Analyser, slutsatser och förslag/rekommendationer som framförs i rapporten är författarnas egna.En fortsatt utbyggnad av fossilfri elproduktion är av stor vikt för att vi ska kunna nå Sveriges energi- och klimatmål. För att utbyggnaden i sig ska vara hållbar är det viktigt att vi redan nu planerar för hur avfallet från dessa elproduktionsanläggningar ska förebyggas, minimeras och sedan hanteras.Det finns redan i dagsläget aktörer som har utvecklat och håller på att utveckla ett flertal olika lösningar för ökad cirkularitet. Dessa möjligheter kan tas tillvara och främjas genom regelbunden kartläggning och genom att arbeta gemensamt inom EU. Genom ett sådant arbete finns det också större möjligheter att etablera industriella värdekedjor i Sverige för hanteringen av avfallet från solcellspaneler och vindturbinblad.En cirkulär hantering av avfall ger ett betydligt mindre avtryck på miljön än det som en linjär hantering ger upphov till. Det är viktigt att de aktörer som tillhandahåller fossilfri elproduktion tar ansvar under hela livscykeln och att det finns goda förutsättningar för aktörerna att göra det.

- Background: A growing literature suggests associations between occupational pesticide exposure and respiratory health. In this study, we aimed to examine the association of exposure to insecticides, fungicides, and herbicides, individually and as a mixture, with respiratory health outcomes and rhinitis in avocado farmworkers from Michoacán, Mexico. Material and methods: We conducted a cross-sectional study of 105 avocado farmworkers between May and August 2021. We quantified 12 insecticide, fungicide, and herbicide metabolites in urine samples collected during two study visits (8–10 weeks apart). We collected survey data on self-reported pesticide use during the 12 months prior to the baseline survey and estimated annual exposure-intensity scores (EIS) using a semi-quantitative exposure algorithm. We also assessed respiratory symptoms, including wheezing, chest tightness, wheezing after exercise, and night cough. We used generalized linear regression models to examine associations of individual urinary metabolite concentrations and annual EIS with respiratory health outcomes and rhinitis. Mixture effects were assessed using Bayesian Weighted Quantile Sum (BWQS) regression. Results: After adjusting for multiple comparisons, we observed mostly null associations of individual pesticide metabolite concentrations and annual EIS with the outcomes of interest. However, in BWQS analyses, we found evidence of a mixture association of urinary pesticide metabolites with increased odds of night cough (OR: 5.34, 95 % CrI: 1.67, 20.62). Pyrethroid metabolites 3-phenoxybenzoic acid and cis- and trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylic acid were the main contributors to this association (43 %). Conclusions: Our findings indicate that exposure to a mixture of pesticides, particularly pyrethroid insecticides, may be associated with night cough in avocado farmworkers.

- Coinfection with multiple HPV types is common in cervical lesions, but the biological significance of the individual infections is difficult to establish. Expression of oncogenic E6/E7 HPV mRNA is correlated to risk of malignant progression, commercial assays for genotyping E6/E7 mRNA of all HR-HPV are lacking.

- DNA-based HPV assays show high sensitivity but poor specificity in detecting high-grade cervical lesions. Assays detecting mRNA of oncogenic E6/E7 show higher specificity, but lack either detection of all high-risk HPV genotypes or the capacity to specify the detected genotypes. Therefore, a real-time PCR assay detecting type-specific E6/E7 mRNA was developed and the clinical performance evaluated. 210 cervical LBC (liquid based cytology) samples from 204 women were analysed for HPV DNA and mRNA with the in house real-time PCR as well as PreTect HPV-Proofer. The sensitivity of real-time PCR mRNA-detection to detect histologically confirmed CIN2+ (cervical intraepithelial neoplasia grade 2 or higher) were 0.91, compared to 0.95 for DNA-analysis. The specificity was 0.68 compared to 0.38, and the positive predictive value (PPV) was higher for mRNA (0.67 vs 0.52) without any loss in negative predictive value (NPV). The sensitivity of the real-time PCR mRNA-test was somewhat higher than for PreTect HPV-Proofer (0.83 vs 0.75), when analysing for the same genotypes. The specificity was similar (0.76 vs 0.77). When analysing for mRNA of the eight most common genotypes in cervical cancer (HPV16, 18, 31, 33, 35, 45, 52, 58), the sensitivity to detect CIN2+ lesions was 0.87 and the specificity 0.74, with a PPV of 0.70. In conclusion, real-time PCR for detection of HPV E6/E7 mRNA transcripts can be a sensitive and specific tool in screening and investigation of cervical neoplasia. The composition of HPV-types in mRNA-testing needs to be further investigated to optimize sensitivity and specificity.

Småbarnsföräldrars konsumentbeteende : En kvantitativ studie om engagemang, säkerhetstänkande, värderingar och omgivningens påverkan på köpbeslut
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Den här boken är resultat av åtta studenters arbete under en uppsatsperiod på tio veckor. Vi började träffas i mars 2008 och i april satte arbetet igång på allvar. Under perioden gjorde studenterna en enkät, samlade in data och analyserade för att komma fram till hur småbarnsföräldrar funderar kring inköp av artiklar åt sina barn. I slutet av maj var arbetet klart! Det har varit ett nöje att få handleda arbetet och jag känner mig stolt att som handledare få presentera den här boken, vars innehåll är väldigt rikt med tanke på under vilken kort period den skapats. Jag hoppas att den kommer att läsas av studenter i marknadsföring som vill ha inspiration till hur undersökningar om konsumentbeteende kan genomföras, eller som helt enkelt bara vill läsa sig mer om ämnet. Vi vill alla tacka några personer som engagerat sig i att hjälpa till med arbetet, genom att låta sig intervjuas, släppa in oss i sällskap av konsumerande föräldrar eller givit synpunkter på arbetet som helhet. Tack till Linn Söderlund, Nicolaus Eberhardt och Maria Hedlund. Cecilia Lindh, Maj 2008

- Purpose: Previous studies have emphasised that women with pre-existing mood disorders are more inclined to discontinue hormonal contraceptive use. However, few studies have examined the effects of combined oral contraceptives (COC) on mood in women with previous or ongoing mental disorders. Materials and methods: This is a supplementary analysis of an investigator-initiated, double-blinded, randomised clinical trial during which 202 women were treated with either a COC (1.5mg estradiol and 2.5mg nomegestrolacetate) or placebo during three treatment cycles. The Mini International Neuropsychiatric Interview was used to collect information on previous or ongoing mental disorders. The primary outcome measure was the total change score in five mood symptoms on the Daily Record of Severity of Problems (DRSP) scale in the intermenstrual phase of the treatment cycle. Results: Women with ongoing or previous mood, anxiety or eating disorders allocated to COC had higher total DRSP -scores during the intermenstrual phase of the treatment cycle in comparison with corresponding women randomised to placebo, mean difference 1.3 (95% CI 0.3-2.3). In contrast, among women without mental health problems, no difference in total DRSP -scores between COC- and placebo users was noted. Women with a risk use of alcohol who were randomised to the COC had higher total DRSP -scores than women randomised to placebo, mean difference 2.1 (CI 95% 1.0-3.2). Conclusions: Women with ongoing or previous mental disorders or risk use of alcohol have greater risk of COC-induced mood symptoms. This may be worth noting during family planning and contraceptive counselling.

Tidskriftsartikel (refereegranskat)abstract
- Bisphenol A (BPA) is considered an endocrine disruptor and has been associated with deleterious effects on spermatogenesis and male fertility. Bisphenol F (BPF) and S (BPS) are struc-turally similar to BPA, but knowledge of their effects on male fertility remains limited. In this cross– sectional study, we investigated the associations between exposure to BPA, BPF, and BPS and semen quality in 556 men 18–20 years of age from the Fetal Programming of Semen Quality (FEPOS) cohort. A urine sample was collected from each participant for determination of BPA, BPF, and BPS concentrations while a semen sample was collected to determine ejaculate volume, sperm concen-tration, total sperm count, sperm motility, and sperm morphology. Associations between urinary bisphenol levels (continuous and quartile–divided) and semen characteristics were estimated using a negative binomial regression model adjusting for urine creatinine concentration, alcohol intake, smoking status, body mass index (BMI), fever, sexual abstinence time, maternal pre–pregnancy BMI, and first trimester smoking, and highest parental education during first trimester. We found no associations between urinary bisphenol of semen quality in a sample of young men from the general Danish population.
