Fig. 7

Teratogenicity of cigarette filter leachates following the 7-day exposure. Occurrence of mouthpart deformities (A) is shown as the proportion of larvae presenting mouthpart deformities in the control and water treatment groups (a = 3, N = 176). Mouthpart deformity scores (B) are shown as mean deformity scores per replicate (n = 7) for the control and water treatment groups (a = 3, N = 21). The boxes display the 25%- and 75%-quartile, dark lines the median, and the whiskers extend to one and a half times the interquartile range. Results shown are from exposures via water, using smoked (sm.) or unsmoked (un.) filters. The asterisks indicate evidence for increased frequency (A) and severity (B) of mouthpart deformities in the treatment groups compared to the control with p < 0.01 for (**) and p < 0.001 for (***)
