Figure 3: Box and whisker plots of private water supply (PWS) drinking water and urinary As.
(a) Total As in drinking water samples plotted with its analytical limit of detection (LOD) (lower dashed line) and the UK As PCV (upper solid line). (b) Individual urinary As species plotted with their respective LODs (dashed lines). (c) Urinary total As and urinary sum of species excluding AB (U-AsIMM). Boxes range from 1st to 3rd quartiles with a median line, lower and upper whiskers are the lowest and highest datum within 1.5 inter quartile range (IQR) of the lowest and upper quartile respectively and circles are outliers. For plotting purposes, speciation data were censored by replacing <LOD values with ½ LOD.
