methoxy polyethylene glycol modified magnetite nanoparticles (pegmns) were synthesized and were 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 spectrophotometry at 236 nm, through batch experiments. the effects of adsorbent dosage, solution ph, contact time, s...
Smallholder farmers in Northern Tanzania grow vegetables that include tomatoes, cabbages and onions and use many types of pesticides to control pests and diseases that attack these crops. Based on the use of questionnaires and interviews that were conducted in Arumeru, Monduli, Karatu and Moshi rural districts, this study investigates farmers’ practices, perceptions and related cost and health ...
In this study, the efficiency of a clean-up method by gel permeation chromatography (GPC) for the separation of pesticides from lanolin is analyzed. The pesticides analyzed belong to two different families, organophosphorous and synthetic pyrethroids. Lanolin, a standard mixture of the pesticides, and a lanolin-pesticides mixture are injected in a GPC column. The recoveries and elution times fr...
BACKGROUND Residential proximity to agricultural pesticide applications has been used as a surrogate for exposure in epidemiologic studies, although little is known about the relationship with levels of pesticides in homes. OBJECTIVE We identified determinants of concentrations of agricultural pesticides in dust. METHODS We collected samples of carpet dust and mapped crops within 1,250 m of...
