 The parameters of applied distributions used in the simulation of exposure variation dimensions (level, repetitiveness/velocity and similarity).
 Exposure groups were simulated based on distributions parameters as shown by N(μ,σ^{2}) representing a normal and logN(μ,σ^{2}) a lognormal distribution. SD stands for standard deviation and 10th, 50th and 90th indicate percentiles of the exposure distributions. The parameters of the distribution are extracted from relevant literature; ^{*}, ^{#}, ^{$} and ^{£} represent the studies in the literature upon which the parameters of the distributions are based. ^{*}: Nordander et al (2008), ^{#}: Hansson et al (2010), ^{$}: Arvidsson et al (2006) and ^{£}: Möller et al (2004).
