Data Submission to Pesticides-Online
� For more convenience, we try to use the data-formats (residue findings) that our users are already utilizing in their lab and translate them into ours.
� Thus, please send us an exampleof your data so that we can look at it and see what we can do.
� If you don't have a LIMS in your lab, we can also offer you a tool basedon Microsoft Access to easily collect your pesticides residue data.
� Which information do we need at least?- Commodity (+ Processing)- Pesticide sought for + value(negatives also interesting!!!)
- Year of analysis- Country of origin- (Other: organic, MRL-violation)

Method Validation Database - Statistics
� currently only data for QuEChERS-Method,but Method Validation Database is flexible to receive data from any other method !
� Recovery data for QuEChERS-Method:- 478 compounds- 44 commodities (apple, raisin, lemon, …)- 17 labs data submitted
� Recovery data of S19- and ChemElute will be submitted soon from different labs.
You’re welcome to submit validation data from your lab!
But how to submit?
