Poster presented at SETAC 2026. Plastic waste in the environment has been suggested as a potential carrier for azoles and other pesticides, which may contribute to the selection and spread of fungal resistance to azole-based medicines and pesticides. Here, we report results from pesticide analyses of plastic litter collected across Norway. Although many of the 120 plastic samples were weathered and small, we detected pesticides and other contaminants on 36 of the samples, including azoles on 13 of them. Azole concentrations ranged from 2-66 µg/kg plastic litter. The concentrations of the other contaminants ranged from 1 to 731 µg/kg plastic litter, with the highest finding of the herbicide fluroxypyr-meptyl on a piece of hayball plastic wrap. 18 of the litter samples with findings were found in forest habitats, whereas 17 samples were sampled from farmland and grassland. The findings suggest certain pesticides and biocides, including azoles, bind more strongly to plastic than previously assumed, allowing contaminants to persist and spread beyond agricultural areas into natural habitats. This raises concerns about environmental transport of antifungal agents and the potential acceleration of resistance development, posing risks to health and ecosystems.

Mattilsynet utfører årlig offentlig kontroll av fremmedstoffer i næringsmidler. I samarbeid med NIBIO undersøkes nivåene av naturlige giftstoffer (plantetoksiner) i mat. Hensikten med overvåkingsprogrammet er først og fremst å overvåke nivået av plantetoksiner for å sikre at forbrukeren ikke utsettes for noe som kan utgjøre en helsefare. Overvåkingen skal også bidra til å sikre at næringsmiddelvirksomheter etterlever regelverket, slik at plantetoksiner ikke overskrider gjeldende grenseverdier. Rapporten presenterer resultater fra 50 prøver som ble hentet fra det norske markedet i 2025. Dette var: • 5 sorghumprøver, 5 teffprøver og 5 barnegrøtprøver som ble analysert for tropane alkaloider, • 5 prøver av spisskummen, 5 urtete-prøver og 5 prøver av urtekrydder med oregano som ble analysert for pyrrolizidinalkaloider, • 10 prøver av bakevarer med valmuefrø ble analysert for opiumalkaloider, og • 10 linfrøprøver ble analysert for cyanogene glykosider (hydrogencyanid) Resultatet av analysene; • Vi påviste ikke tropane alkaloider i noen prøver. • Det ble funnet tre prøver over grenseverdi for pyrrolizidinalkaloider. To av disse prøvene var fra tørket oregano og én var fra urtete av sitronmelisse. Kun urteteen var en overskridelse av grenseverdien etter fratrekk for usikkerheten. • Alle prøver av bakevarer med valmuefrø hadde funn av opiumalkaloider under grenseverdien. • Tre prøver av linfrø inneholdt hydrogencyanid over grenseverdien. Funn over grenseverdi blir fulgt opp overfor importør/virksomheten av produktet.

Phenotypic plasticity and local adaptation jointly shape plant responses to environmental variation, but their relative contributions and trait-specific interactions remain poorly understood. (1) We quantified metabolites and measured growth, reproduction and herbivore resistance-related traits in 15 Fragaria vesca genotypes from a European latitudinal gradient grown reciprocally in four common gardens over two years. (2) Environment explained most trait variance (30%), followed by genotype × environment interactions (18%) indicating evolved plasticity, then genotype (9%). (3) Northern genotypes exhibited greater plasticity in stress-related metabolites but more canalization in growth-related traits, while southern genotypes maintained constitutively high levels of protective metabolites; this resulted in latitude shaping more than 4% of plasticity profiles. (4) Long-term temperature at origin outperformed precipitation in predicting trait variation across all categories. Synthesis. Plasticity dominates over local adaptation along climate gradients but evolves in a trait-specific manner as a heritable target of selection, buffering populations against climate shifts while also shaping the pace of genetic tracking, critical for predicting range dynamics under climate change.

Evaluation of biochar-assisted contaminant immobilization as a soil remediation technology must consider the trade-off between the positive effects of reduced toxic impacts through soil cleanup and climate change mitigation through carbon storage, and the negative impacts associated with contaminants introduced to soil with the biochar. Addressing this trade-off is challenging, as existing models and characterization factors used in life cycle impact assessment (LCIA) are generally not representative of conditions at contaminated sites, particularly in the presence of sorbents such as biochar. In addition, comparative toxicity potentials (CTPs) of most per- and polyfluoroalkyl substances (PFAS) compounds are not available for soils. To address these challenges, we applied the USEtox framework to quantify environmental fate, ecosystem exposure, and ecotoxicological effects of perfluorooctanoic acid (PFOA) as the remediation target, and several metals and polycyclic aromatic hydrocarbons (PAHs) introduced via biochar amendment. The resulting CTPs were used in the LCIA phase of a life cycle assessment (LCA) of soil remediation based on the LC-Impact methodology. Biochar had a significant influence on the CTPs of PAHs, a moderate effect on PFOA, and a limited effect on metals. The trade-off between the immobilization of PFOA and the introduction of PAHs and metals was outweighed by the benefits of carbon storage and avoided incumbent waste management. These results suggest that the implementation of biochar-assisted remediation should be primarily guided by the carbon storage potential of the biochar and the characteristics of incumbent feedstock treatment pathways, whereas the effect of biochar on PFOA immobilization was less influential.

This data article presents a multi-source dataset of satellite-based auxiliary data designed for forest modelling and monitoring. The dataset integrates annual medoid composites derived from Sentinel-1, Sentinel-2, and Landsat imagery, together with spectral indices, Landsat-based 3I3D change metrics, forest mask and forest type layers, and terrain variables derived from the Copernicus GLO-30 DEM, offering comprehensive information on forest cover, spectral behavior, and change metrics. It provides harmonized predictors across seven European countries, ensuring consistency, scalability, and ease of use for researchers developing or validating models to understand forest dynamics and estimate forest-related variables such as biomass or canopy recovery. A curated subset of the dataset is distributed via Zenodo, along with direct public access links to the complete multi-terabyte archive. The data support applications in forest biodiversity conservation, carbon monitoring, biomass modelling, and climate-change impact assessment.

Ny forskning viser at gran fra Nordland og Troms tilfredsstiller kravene til konstruksjonsvirke når den styrkesorteres etter gjeldene regler. Skogen som ble plantet før og etter 1945 kan etter hvert avvirkes, og representerer en betydelig ressurs for bygg og rehabilitering. Utfordringen er ikke kvaliteten på råstoffet – men trolig manglende lokal foredling og bruk.
