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 another....

Pollution of Lake Bosomtwe is a major concern in Ghana due to its derived socio-economic benefits such as employment, ecotourism and protein source the people basin. Besides these benefits, lake water used for domestic purposes has since served drinking people. However, use agrochemicals within basin intensified last decade. The problems associated with fertilizer pesticide seem carry it higher...

The aim of this study was to investigate the seasonal and spatial variations in concentrations a widely used organophosphorous pesticide (OPP), diazinon, associated risk posed by OPP surface water from three largest rivers located northern province Iran: Haraz, Talar Babolrood rivers. These are agriculture Mazandaran, exposed high doses organophosphorus pesticides, especially diazinon. concentr...

Two multiresidue methods were developed to determine pesticides in air collected in California. Pesticides were trapped using XAD-4 resin and extracted with ethyl acetate. Based on an analytical method from the University of California Davis Trace Analytical Laboratory, pesticides were detected by analyzing the extract by gas chromatography-mass spectrometry (GC-MS) to determine chlorothalonil,...

background: since organophosphorus pesticides are widely used for industry and insect control in agricultural crops, their fate in the environment is very important. pesticide contamination of surface water has been recog­nized as a major contaminant in world because of their potential toxicity towards human and animals. the objec­tive of this research was to investigate the influence of variou...

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...

Methoxy polyethylene glycol modified magnetite nanoparticles (PEGMNs) were synthesized and characterized by scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), and X-ray diffraction (XRD). The adsorption of diazinon onto PEGMNs was investigated by UV-Vis spectrophotometry at 236 nm, through batch experiments. The effects of adsorbent dosage, solution pH, contact time, solut...

Diazinon is an organophosphate which exerts tissue damages by generating free radicals thereby inducing oxidative stress. The purpose of this study is to determine the protective effect of Salvia officinalis L.extract on testes of rats intoxicated by diazinon. In this experimental study, 45 mature male rats were equally divided into three groups of Control (C), Diazinon (DZN) and Diazinon-Extra...
