Pesticides residue analyses from 83 samples picked up from 20 packinghouses in the area of Souss Valley, in the southern part of Morocco, revealed that only one sample was found to have slightly higher chloropyriphos ethyl residues. All other results showed the presence of pesticides at various levels, but within the EU regulation. The compounds frequently found are methidathion, chloropyriphos ethyl, malathion, dimethoate and parathion-methyl, respectively, at a rate of 43%, 33%, 11%, 7% and 4% of the number of samples. The study on dissipation of some pesticides in fruits showed that chloropyriphos ethyl is more persistent in the fruit and requires about 80 days from the application date to reach a value equal or lower than authorized maximum residue level (MRL) for this pesticide in the EU markets. In contrast, only 7 days from the time of application are necessary for methidathion, malathion and dimethoate to reach the acceptable limit. [ABSTRACT FROM AUTHOR] |
