HUMNap project 2 major HUMNap objectives: 1) determine associations between the air pollutants and biomarkers of exposure, 2) knowledge transfer among partners 3 study locations: 1) under high traffic air pollution pressure, 2) under high industrial air pollution pressure, and 3) reference site 5 work packages: 1) project management, 2) air pollution monitoring, 3) human biomonitoring, 4) knowledge transfer, 5) dissemination The outline of the HUMNap project PhD Student Section PhD programme Enrolment in University of Zagreb, Faculty of science PhD programme in natural sciences - biology is planned for year 2021 Training A minimum of 3 international workshops and partner visits are planned for improvement of lab skills and knowledge transfer. Conferences A minimum of 4 domestic and international conferences are planned for data dissemination and networking. Genetic toxicology Assessing biomarkers of early DNA damage in human blood and buccal epithelial cells from volunteers. Mechanism of action Determination of oxidative changes to macromolecules , as well as assessing changes in enzymatic and non-enzymatic oxidative stress defense. Automation Knowledge transfer on automated scoring processes for high-throughput slide analysis.
