# Determine the SSLRC mobility classification for a chemical substance from its Koc

This implements the method specified in the UK data requirements
handbook and was checked against the spreadsheet published on the CRD
website

## Usage

``` r
SSLRC_mobility_classification(Koc)
```

## Arguments

- Koc:

  The sorption coefficient normalised to organic carbon in L/kg

## Value

A list containing the classification and the percentage of the compound
transported per 10 mm drain water
