“…If approved, the proposed technique would amend the National Primary Drinking Water Regulations to eliminate the liquid/liquid extraction step in the current USEPA test procedure for these four organochlorine pesticides, replacing it with a solid-phase extraction technique. Comprehensive reviews of analytical procedures for pesticide analysis from water have been published (24)(25)(26).…”

A simple and rapid method for extraction of seven dinitroaniline herbicides from human whole blood and urine using Sep-Pak C18 cartridges is presented. After mixing with distilled water, whole blood and urine samples containing the herbicides were loaded on Sep-Pak C18 cartridges and eluted with chloroform-methanol (9:1). The recovery of the seven compounds that were added to whole blood and urine was more than 91%. The herbicides were detected by capillary gas chromatography (GC) with electron-capture detection (ECD), surface-ionization detection (SID), nitrogen-phosphorus detection (NPD), and flame-ionization detection (FID). GC-ECD generally gave the highest sensitivity for all herbicides, whereas GC-FID gave the lowest sensitivity. Isopropalin could be detected by GC-SID with a sensitivity comparable with that of GC-ECD; high sensitivity could also be obtained for isopropalin, pendimethalin, and nitralin using GC-NPD. The calibration curve for the seven herbicides measured by GC-ECD showed linearity in the range of 0.047-3.0 pmol on-column. The detection limits of the herbicides were 24-45 fmol on-column for whole blood and 19-40 fmol on-column for urine.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
