GST activity of flies body after exposure and co-exposure to VCH and MeHg+ for one (a and b)or three days (c and d). Kinetic readings were expressed as the mean in a and c (standard errors were omitted for better viewing) and delta per minute as mean ± standard error in b and d. Results were analyzed by four-way ANOVA (VCH x MeHg+ x age x time of kinetic reading which was treated as repeated measures) and were considered significantly different when p < 0.05
