A novel GC-ITD-MS method have

been developed and successfully validated for

the determination of 37 pesticides in fruit jams.

In order to facilitate the sample handling and

to reduce the interference of the high sugar

content of the jams the samples were slurried

with water. The pesticides extraction was done

with the sulfate QuEChERS method using PSA

for clean-up. The method was validated by the

analysis of spiked samples at the concentrations

of 10, 20 e 50 μg kg-1 (n=6). In total 41

pesticides were studied and 37 fulfilled all the

requirements for the validation (recoveries from

70-120% and RSD ≤ 20%). So, the reporting

limit (RL) was established at 10, 20 e 50 μg

kg-1 for 26 (64%), 4 (10%) e 7 (17%) pesticides,

respectively. Three compounds (7%) were not

detected at the studied concentrations levels

and one pesticide (2%) was detected but did

not meet the requirements for validation. The

method is easy to implement, uses equipments

commonly available in laboratories and can be

recommended for routine multiresidue analysis

of jams.
