Furthermore, input of DDX into the lakes or their surrounding reservoirs via LRAT is possible and has been reported . However, contributions through this pathway should be minor in regard to the extent of direct depositions that took place in the examined area. evaluated the distribution of 76 pesticides in agricultural topsoil samples from across the EU in 2015. DDT and its TPs where the second most frequently found compounds only after the herbicide glyphosate which was applied much more recently. Accordingly, the most common TP was 4,4'-DDE with median and maximum of 20 and 310 µg•kg -1 , respectively, while for 4,4'-DDD it was 10 and 40 µg•kg -1 . In the current study, concentrations in the youngest layers dating back to 2010-2015 were between <LOD and 15.71 for 4,4-DDE and <LOD and 22.07 µg•kg -1 for 4,4'-DDD. evaluated data from 73 peer-reviewed articles and calculated median concentrations for several legacy pesticides of agricultural and background soils from all over the world. The results were divided into two distinct periods Values of 4,4'-DDT declined from 16.22 to 8.71 µg•kg -1 in agricultural soils and from 1.23 to 0.91 µg•kg -1 in background soils. Similar values and trends were shown for 4,4'-DDE: 12.02 to 7.76 µg•kg -1 and 0.98 to 0.51 µg•kg -1 in agricultural and background soils, respectively. In the present study, 4,4'-DDD which is assumed to represent its DDT counterpart, is found at a median concentration of 7.66 µg•kg -1 in the first period and at <LOD in the second. 4,4'-DDE stays more or less the same (7.23 and 8.23 µg•kg -1 ), at concentrations comparable to those from agricultural soils in the second period from Camenzuli's study. DDD was the predominant TP in other studies concerning OCP concentrations in sediments , and in two of them examining river sediments almost all DDT was converted . On the other hand, there are also many studies in which DDE was the predominant TP (e.g. and attributed this to input of mainly strongly weathered soil material (i.e. from agriculture), and little direct input of DDT into the lake.
