Pesticides and Herbicides: A Growing Concern in the Global Food Supply Chain

On Demand Webcast:

Toxaphene, a complex organochlorine pesticide, has been the most
broadly applied pesticide in the United States and other countries since
the 1970s. The United States banned the use of this pesticide by 1990
after the toxicity and persistence of toxaphene became unquestionable.
In 2002, the U.S. EPA was contacted regarding concerns about toxaphene
residual wastes and degradation products into streams and estuaries.
Traditional methods could potentially underestimate residues once the
toxaphene weathering process had begun in the environment. Because
of the potential for toxaphene underestimation, degradation products
need to be determined with highly sensitive methods. These events
have culminated in the validation of a suitable extraction method for
weathered toxaphene and its degradation products in fish tissues using
Accelerated Solvent Extraction.

Glyphosate, a widely used broad-spectrum herbicide, is monitored for its
presence in food. Generally the GC-MS method developed by Alferness
is used for analysis. This method is both time consuming and has limitations
with limits of quantification across a range of food commodities.
By employing suppressed ion chromatography – mass spectrometry
(IC-MS/MS) for glyphosate analysis, the required reporting limits can be
achieved without time-consuming derivatization. Detection limits as
low as 1μg/kg have been achieved using concentrator techniques.
