<h1>Calculate predicted environmental concentrations in sediment from surface
water concentrations</h1>

<h2>Usage</h2>
<pre><div>PEC_sw_sed(PEC_sw, percentage = 100, method = "percentage", sediment_depth = 5, water_depth = 30, sediment_density = 1.3, PEC_sed_units = c("µg/kg", "mg/kg"))</div></pre>
<h2>Arguments</h2>
<dl>
<dt>PEC_sw</dt>
<dd>Numeric vector or matrix of surface water concentrations in µg/L for
which the corresponding sediment concentration is to be estimated</dd>
<dt>percentage</dt>
<dd>The percentage in sediment, used for the percentage method</dd>
<dt>method</dt>
<dd>The method used for the calculation</dd>
<dt>sediment_depth</dt>
<dd>Depth of the sediment layer</dd>
<dt>water_depth</dt>
<dd>Depth of the water body in cm</dd>
<dt>sediment_density</dt>
<dd>The density of the sediment in L/kg (equivalent to
g/cm3)</dd>
<dt>PEC_sed_units</dt>
<dd>The units of the estimated sediment PEC value</dd>

PEC calculator</p>
