<h2>Description</h2>
<p>Calculates long term accumulation PEC values. Assumes that the complete load to soil during the
time specified by 'interval' (typically 365 days) is dosed at once. As in the PPR panel opinion
cited below (PPR panel 2012), only temperature correction using the Arrhenius equation is performed.
By default, PEC values for the scenarios as defined in the EFSA guidance
(2015, p. 13) are calculated.</p>
