- 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,σ2) representing a normal and log-N(μ,σ2) a log-normal 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). We refer to the reference list for detailed information.
