Atrazine: a lively chemical journey
Atrazine is a widely used pesticide, particularly popular in corn plantations for its herbicidal properties of killing and preventing the growth of certain weeds and grasses. Evidence of its neurotoxicity, hormone disruption and reproductive toxicity led the EU to ban the chemical in 2003. Despite …

Determination of Atrazine Concentration in Freshwaters Using Fluorescence Spectroscopy
<p>Atrazine is the most widely used herbicides in USA, but its negative impact on aquatic ecosystem cannot be over-looked. Atrazine was traditionally determined through liquid/gas chromatography or IR spectroscopy. However, these methods are either time-consuming or costly, so fluorescence …

Degradation of atrazine utilizing triazine hydrolase (TrzN) from Arthrobacter aurescens TC1
… notably, TrzN can hydrolytically dechlorinate atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) to its less toxic derivative hydroxyatrazine. Atrazine is a widely used synthetic herbicide which has an extensive list of potential environmental and health concerns. TrzN is a prime …

Influence of phytobland oils on the activity of foliarly applied atrazine
… oro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) as influenced by various phytobland oils was studied at three locations in Virginia. Postemergence control of grasses (Digitaria sanguinalis (L.) Scop., Panicum dichotomiflorum Michx., and Setaria spp.) was increased by single and repeated …
