Experimental work was carried out to investigate the influence of impeller speed, granulation time, binder mass and their interactions on granule size distribution, mean size and binder content distribution in a conical high shear granulator. It was observed that the response of high shear granulation to changes in process parameters varies significantly from one operating condition to anot...

The present research aimed to determine acute toxicity and evaluate the effect of sub-lethal concentrations of diazinon on some haematological and immunological parameters of Barbus sharpeyi by the Organization for Economic Cooperation and Development methods. Juvenile B. sharpeyi were exposed to 0, 5%, 10% and 25% 96h LC50 concentrations of diazinon for 21 days. Blood samples were taken after ...

the pollutants due to effect on the immune system of fish increase fish sensitivity to pathogens. diazinon is one of the most used organophosphates pesticide in many agricultural areas. this study aimed to evaluate the effect of diazinon on the immune system of rainbow trout ( oncorhynchus mykiss ) and application of milk thistle plant, vitis vinifera extract to reduce the adverse effects of th...

About 12 months ago Captec Pty Ltd registered a diazinon-based dipping product for sheep called Diprite. Diprite included new (patented) label instructions that enabled application of a consistent dose of chemical to all sheep dipped. Many pesticides ‘strip’ when used in sheep dips (including diazinon). Stripping is the process whereby the pesticide leaves the dip faster than the water removed ...

The primary purpose of this chapter is to provide public health officials, physicians, toxicologists, and other interested individuals and groups with an overall perspective on the toxicology of diazinon. It contains descriptions and evaluations of toxicological studies and epidemiological investigations and provides conclusions, where possible, on the relevance of toxicity and toxicokinetic da...

diazinon is one of the highly consumed organophosphorous pesticides. it inhibits cholinesterase enzyme in animal tissues. due to permanent residence in agricultural drainage channels, the swan mussel (anodonta cygnea) can be considered as one of the most suitable indicators of such pollutants. at the present study, acethyle cholinesterase activity of a. cygnea was measured when exposed to vario...
