معرفی
Gunnar Johanson is a Senior Professor at the Institute of Environmental Medicine, Karolinska Institutet, specializing in toxicology and risk assessment. He leads the Unit of Integrative Toxicology and contributes to Lena Palmberg's Lung Toxicology research group. His career includes a PhD in toxicology from Karolinska Institutet (1988) and appointment as a professor (1999). Johanson chairs the Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals (since 1999) and serves on international committees like EU SCOEL and AEGL. His research focuses on toxicokinetics, chemical exposure (indoor air, occupational hazards, disasters), and risk assessment, with emphasis on inhalation/dermal uptake, zebrafish embryo studies, and computer modeling. Key contributions include pioneering work on glycol ether skin penetration and vapor uptake, as well as evaluating perfluoroalkyl acids in drinking water.
Education: PhD Toxicology (Karolinska Institutet, 1988), Docent (Uppsala University, 1999).
Research Interests: Experimental toxicology, chemical exposure pathways, risk assessment harmonization, occupational safety, and environmental health policy. He investigates biomarkers of exposure (e.g., ethanol washout kinetics), nanomaterial biokinetics, and acute chemical effects in human models.
Recent Article Trends: Recent work addresses heated tobacco product toxicity, chlorophenol indoor exposure, PFAS bioaccumulation, and SARS-CoV-2 pathogenesis in lung models. His studies bridge experimental methods (e.g., air-liquid interface models) with population-level health impacts.
Expert Roles: Vice-chair of Swedish Criteria Group for OELs, EU-LCI working group, and AEGL committee. He advocates for unbiased expert committees and harmonized occupational exposure limits.
Labs/Teams: Core member of the Unit of Integrative Toxicology and collaborator in transnational research networks like the Indo-Swedish Workshop on biomass smoke exposure.
