Abstract
Atrazine is a worldwide herbicide used to control pre- and post-emergence
broadleaf and grassy weeds in major crops. Being both effective and
inexpensive, it is well-suited to production systems with very narrow profit
margins, asis often the case with maize. However, due to atrazineís ground
water contamination potential and its association with birth defects and
menstrual problems when consumed by humans at concentrations even
below governmentstandards; environmental media monitoring for atrazine
are inevitable. The objective of this study was to investigate a proposed
ìsafe, cheap and relatively fastî analytical technique for the routine
monitoring of atrazine in soil samples by high performance liquid
chromatography equipped with ultra-violet detector and/or gas
chromatography mass spectrometry. The method uses acetonitrile as the
extracting solvent, and a self-packed activated silica gel for clean-up of
extract. The proposed method exhibited good sensitivity and recovery, and allowed
for rapid analysis. For soil analysis, a single chemist could prepare test
solutions from 15 corresponding homogenized samples within 4 hours
