چکیده

According to The Pesticide Manual, more than 700 pesticides are currently approved for use around the world [1]. About 600 more were used in the past, but are either banned or no longer marketed. In spite of their discontinuance, some of these still persist in the environment where they may bioaccumulate in the flora and fauna. Many pesticides or their degradation products can be found at trace levels in food and beverages; in soil, water, and air; in aquatic and terrestrial flora and fauna; and in human blood, adipose tissue, and breast milk. The World Health Organization has classified pesticides into five groups based upon their acute toxicity to humans [2]. The categories range from “Acutely Hazardous” to those that are “Unlikely to Present Acute Hazard in Normal Use.” Certain pesticides are classified as persistent organic pollutants (POPs), carcinogens, teratogens, or endocrine disrupters. It is now common to analyze for Comprehensive Pesticide Screening by GC/MSD using Deconvolution Reporting Software

Reducing Analysis Time Using GC/MSD and Deconvolution Reporting Software Application

Analyzing a complex matrix can be accomplished using multiple specific detectors, but a significant time savings is realized using GC/MSD. Using an available Retention Time Locked database with Deconvolution Reporting Software (DRS) adds a second “expert” opinion. GC/MSD with DRS provides the fastest methodology to the fewest number of false positives/negatives with the greatest confidence in t...

Screening for Pesticides in Food Using the Japanese Positive List Pesticide Method: Benefits of Using GC/MS with Deconvolution Reporting Software and a Retention Time Locked Mass Spectral Database Application

In 2006, the Japanese Ministry of Health, Labour and Welfare introduced a new system for the regulation of pesticides, feed additives, and veterinary drugs. This “Positive List” system stipulates that only compounds on the approved list can be used in food production and provides the framework for regulation of these compounds. These new regulations have increased the need for analytical method...

Can "Deconvolution" Improve GC/MS Detectability?

This study uses 35 pesticides spiked in spinach extracts at the 50 ppb level to find the optimal AMDIS deconvolution settings. Additional advantages of using deconvolution versus MSD ChemStation, to find more compounds in an extract are also discussed. The detectability of compounds in a complex matrix is significantly improved with deconvolution. This can also be viewed as better or increased ...

Screening for 171 Volatile Organic Air Pollutants Using GC/MS with Deconvolution Reporting Software and a New Indoor Air Toxics Library Application

A retention-time-locked mass spectral database was created specifically for indoor air analysis by thermal desorption/gas chromatography/mass spectroscopy (TD/GC/MS). This Indoor Air Toxics Database contains locked retention times and mass spectra for 171 volatile and semivolatile organic compounds that are targets in various indoor air methods. In combination with Agilent's Deconvolution Repor...
