The objective of this study was to evaluate the effect of phosalone on some mineral contents, morphological abnormalities and spinal deformities in common carp (Cyprinus carpio, L.1758). Fish were exposed to 0.15, 0.30 and 0.60 mg L of phosalone using a semi-static exposure regime for 14 days. Experiments were conducted in triplicate for control treatments and phosalone concentrations. At the e...

BACKGROUND Transfer of pesticides from environment to animal products is inevitable, so the purpose of the present work was to evaluate phosalone consumption via feeding with or without sodium bentonite (SB) on performance, blood metabolites and its transition to milk of Iranian Baluchi sheep. METHODS Twenty Baluchi ewes were divided into four treatments (P1 as control, P2, P3, and P4) of fiv...

To elucidate the role of acetylcholinesterase (AChE) enzyme in BBB function, phosalone, an organophosphorous compound, was studied using rat brain micro vessels in vitro. Phosalone at 100 mg/kg b. wt. induced convulsions and caused a significant inhibition of AChE resulting in increased permeability as assessed by volume distribution. The anaesthetized phosalone treated group also increased per...

A kinetic study of the degradation of phosalone in an alkaline medium was undertaken by using a pneumatic stopped-flow system. A rapid semiautomatic method is proposed for determining phosalone. Linear calibration graphs up to 8.0 x 10(-5) M (detection limit = 1.40 x 10(-6) M) were obtained, with a measurement period of only 3.5 s per sample and a relative standard deviation of 1.4%. Several pe...

The benzoylphenyl urea insect growth regulators (IGRs), diflubenzuron, alsyston, CGA 112913, UC 62644 and Thuringiensin, were tested on adult and late third instar Trioxys pallidus and first instar walnut aphids. The organophosphates, phosalone and azinphosmethyl were used as positive controls. The IGRs and Thuringiensin were not acutely toxic to adult and larval Trioxys when contact, topical a...

The dynamics of incurred pesticide residues in apples, variety Melrose, was monitored during their cold storage at 1–3 C for 5 months. Of 21 active ingredients contained in pesticide preparations applied within four experimental pre-harvest regimes, only six fungicides (captan, cyprodinyl, dodine, pyrimethanil, tebuconazole, tolyfluanid) and one insecticide (phosalone) were detected at the time...

in this experiment, fermentation parameters of a tmr ration determined with different levels of phosalone as an organophosphate pesticide (0, 100, 250, 500, 750 and 1000 ppm) and bentonite (0, 1 and 2 %dm of tmr) using in vitro batch culture and gas production techniques. the results from gas production showed that cumulative gas production for 96h after incubation significantly decreased with ...

Organophosphate pesticides exert their toxic effects by cholinesterase inhibition and the consequent prolongation of the undesirable effects of accumulation of acetylcholine. The signs of toxicity include tremors, convulsions, lachrymation, defecation etc. However, sustained cholinesterase inhibition through sustained administration of organophosphates would lead to the gradual disappearance of...
