Lead Engineer
Biography
Employed in NIBIO since 2016. My primary work consists of different aspects of the analysis of pesticide residues in vegetable, animal, and environmental samples (water, soil, etc.). I can be contacted regarding technical questions related to the analytical services offered by our laboratory, questions related to legislation and/or administrative questions.
I have technical competence related to GC-MS/MS and LC-MS/MS analysis of pesticide residues, where part of my work consists of method development and validation. I am also responsible for data management in our departments LIMS.
Key points:
- Legislation
- Mattilsynet (Norwegian Food Safety Authority)
- Knowledge Development
- Pesticides
- GC-MS/MS
- LC-MS/MS
- LIMS
- Method development
- Validation

Currently used pesticides (CUPs) were introduced to have lower persistence and bioaccumulation, and lesser bioavailability towards non-target species. Nevertheless, CUPs still represent a concern for both human health and the environment. India is an important agricultural country experiencing a conversion from the use of obsolete organochlorine pesticides to a newer generation of phytosanitary products. As for other developing countries, very little is known about the transfer of CUPs to the human diet in India, where systematic monitoring is not in place. In this study, we analyzed ninety four CUPs and detected thirty CUPs in several food products belonging to five types: cereals and pulses, vegetables, fruits, animal-based foods, and water. Samples were taken from markets in Delhi (aggregating food produced all over India) and in the periurban area of Dehradun (northern India) (representing food produced locally and through more traditional practices). Overall, chlorpyrifos and chlorpropham were the most detected CUPs with a detection frequency of 33% and 25%, respectively. Except for vegetables and fruits, the levels of CUPs in all other food types were significantly higher in samples from Delhi (p < 0.05). Exposure dosage of CUPs through different food matrices was calculated, and chlorpropham detected in potatoes had the maximum exposure dosage to humans (2.46 × 10−6 mg/kg/day). Risk analysis based on the hazard quotient technique indicated that chlorpyrifos in rice (2.76 × 10−2) can be a concern.
