Fig. 5From: Calibration of the SPEARpesticides bioindicator for cost-effective pesticide monitoring in East African streamsDistribution of physicochemical parameter values at the study sites. The violin plot shows the kernel probability density of the data points across the parameter values. White points indicate the median, black boxes the interquartile range, and black lines 1.5 × the interquartile range. Light-grey boxes indicate the range of values considered typical or recommend for streams with good water qualityBack to article page
