Fig. 3
shows the results obtained for the pesticides quantified at higher levels.
In general, this water body was more contaminated by pesticides (primarily
herbicides) during the dry period. Thus, bentazone, terbuthylazine,
MCPA, diazinon, CPF and metolachlor were detected at higher levels in
June and July, after the first runoff-producing rainfall in May and soon
after their application, namely in vineyards and in the intensive olive
crops. This process has been previously well documented in various
works conducted in the Mediterranean region
