Containment
Trace Element and Stable Isotope Analysis to
Determine Origin of Fruits and Vegetables
Intercepted in the Marketplace – A Pilot Project
Purpose and Objectives:
•
•
•
•
•
•
Collaboration between CPHST Gulfport and Carson Watts
DHS laboratory, Savannah
Build on existing DHS methods for classifying and
discriminating the geographic origin of commodities
Assemble a geo-referenced data library of trace elements for
fresh commodities (mango) from multiple countries.
Use the assembled data library to classify unknown origin
samples as either domestic or foreign source.
Determine carbon and nitrogen contents and stable carbon,
nitrogen and oxygen isotopic compositions of commodities
from various countries.
Use stable isotope ratios to discriminate the geographic origin
of commodities.
Conclusions
• FY10 AQI 15 QPS projects totaling more
than $500,000
• Building new AQI research lab in Miami to
be completed end of FY11
• FY11 AQI research funding will be down
because of decline in AQI user fees
collected during recession
