a Relative abundance of derived DOM molecules that identified in vitro toxicity endpoints (red square scatters) and their proportion of all in vitro toxicity assays that hit toxicity endpoints (blue circular scatters). The median (center lines), 1.5 × the interquartile range (whiskers), and outliers (points beyond the whiskers) for the blue circular scatters are shown synchronously in the panel. b Numbers of types of gene symbol hits in Tox21 10 K activity assays. The bar + data overlap plot shows the median (bar), whiskers representing 1.5 × the interquartile range, outliers as points beyond the whiskers. The vertical axis represents absolute number. c Different kinds of gene symbol hits in Tox21 10 K activity assays, where only gene symbols with more than two hits for derived DOM molecules in each DOM species were shown. All gene hit symbols and number of hits were shown in Supplementary Table 6. The small bars in the stacked bars represent the median and the whiskers at the top of each small bar represent 1.5 × the interquartile range. The vertical axis represents absolute number. d In vivo assay data including bioaccumulation factor, fish biotransformation days, and biodegradation half-life days. The bar + data overlap plot shows the median (bar), whiskers representing 1.5 × the interquartile range, outliers as points beyond the whiskers. The methods and p-values for statistical hypothesis tests of biodegradation half-life days for different DOM species were shown in the Source Data file.
