From 1st of February till 17th of March 2020, I was at University of Aveiro at Centre for Environmental and Marine Studies (CESAM) for fulfilling my obligate internship. I worked in ecotoxicological lab where I performed an acute test with Niclosamide (Lampricide, moluscocide, pharmaceutical) on Ch. riparius non-biting midge and I started a chronic test (growth, biomarkers, emergence etc. as observed endpoints). Unfortunately, I could not finish the study because of Coronavirus. Internship was partially covered by the Erasmus+ grant.
