<h1>Read TOXSWA surface water concentrations</h1>
</div>
<p>Read TOXSWA hourly concentrations of a chemical substance in a specific
segment of a TOXSWA surface water body. Per default, the data for the last
segment are imported. As TOXSWA 4 reports the values at the end of the hour
(ConLiqWatLayCur) in its summary file, we use this value as well instead
of the hourly averages (ConLiqWatLay).</p>

the segment number.</p></td>

<tr>
<th>substance</th>
<td><p>For TOXSWA 4 .out files, the default value "parent" leads
to reading concentrations of the parent compound. Alternatively, the substance
of interested can be selected by its code name.</p></td>

<tr>
<th>total</th>
<td><p>Set this to TRUE in order to read total concentrations as well. This is
only necessary for .out files as generated by TOXSWA 4.4.2 or similar, not for .cwa
files. For .cwa files, the total concentration is always read as well.</p></td>

maximum time weighted average concentrations and areas under the curve.</p></td>

generating event statistics.</p></td>
