The object of this study was the kinetics of disappearance of linuron in soil, under
laboratory conditions. Compared two methods of indirect determination of half life time and
estimation accuracy of the calculations. These were the analytical method (for example, a
simple first-order reaction model) and the graphical method (assuming a linear decay of the
active substance). According to the current international standards assume that a measure of
uncertainty of measurement was the double value of standard deviation. Calculated expanded
uncertainty of measurement of the absolute half period and the relative uncertainty. Depending
on the method used was different, but similar half-life values (36.1 and 37.3 days). It was found
that the analytical method was more accurate (relative uncertainty 3.0%) than the graphics
(uncertainty 4.8%).
