OBJECTIVES Effects of acute exposure to organophosphorous pesticides (OPs), chlorphenvinphos (CVP) or chlorphyriphos (CPF) on amphetamine (AMPH)- or scopolamine (SCOP)-induced open-field locomotion were compared in rats. MATERIALS AND METHODS CVP and CPF were administered intraperitoneally, both at doses resulting in about 50% inhibition of erythrocyte acetylcholinesterase (rbcAChE). The pest...

A rapid multi-residue method was developed for the determination of 20 organophosphorous pesticide residues in leeks by gas chromatography coupled to triple quadrupole mass spectrometry (GC–QqQMS/MS). The method was based on the modified QuEChERS sample preparation method. After microwave pre-treatment, leek samples were extracted with acetonitrile containing acetic acid 0.1% and cleaned by dis...

background: the german cockroach, blattella germanica (l), is a world wide hygienic pest that is very difficult to control. extensive usage of insecticides may develop resistance to a variety of insecticides, causing failure to control. this study was designed to determine resistance of hospital-collected strains of the german cockroach to carbamate and organophosphorous insecticides. methods: ...
