This study investigated the levels of DNA strand breaks and formamidopyrimidine DNA glycosylase FPG sensitive sites, as assessed by the comet assay, in peripheral blood mononuclear cells PBMC from healthy women from five different countries in Europe. The samples were analysed in 13 different laboratories for DNA damage, which is measured by the comet assay.

Programme and Abstract Book Authors: Data obtained with both methods were compared and reproducibility of the methylation-sensitive modified version of the comet assay determined. The essential comet assay: This study aimed i to quantify airborne cultivable bacterial and fungal concentrations in four different types of indoor environment as well as to identify the recovered fungi; ii to assess the impact of outdoor bacterial and fungal concentrations on indoor air; iii to investigate the influence of carbon dioxide CO2temperature and relative humidity on bacterial and fungal concentrations; and iv to estimate bacterial and fungal dose rate for children 3e5 years old and 8e10 years old in comparison with the elderly.
