During a research project to improve the performance and operation of shower dips, a series of measurements of the diazinon based dip-wash concentrations were taken. These measurements, although not replicated, indicated that the concentrations were falling to levels which were considered to be too low. As a result a replicated trial was conducted on the same shower dip, modified as per the fin...
A semiconductor composite photocatalyst, TiO2-ZnO, was synthesized by precipitating ZnO on the surface of commercial TiO2 (aeroxide P25), and used for the photodegradation of diazinon in a 12 W UVC batch photoreactor. Scanning electron microscopy (SEM) investigation revealed a plausible hybridization of TiO2 and ZnO in the composite. Ultraviolet visible (UV-Vis) spectroscopy confirmed a red shi...
An interlaboratory study was conducted to compare pesticide recovery from Empore C(18) and Speedisks C(18)XF solid phase extraction disks after shipping. Four pesticides were used for the comparison of the two disk extraction materials: atrazine, diazinon, metolachlor, and tebuconazole. These pesticides were chosen to provide a range of physiochemical properties. Water samples were extracted on...
Pesticides are one of the major pollutants in the environment. The residue of pesticides has been reported to be at a critical level in agricultural crops, especially in greenhouse crops. Tomato is considered as an important vegetable in Iranian food basket and is produced in fields and greenhouses. So, the current study aimed to assess diazinon and oxydemeton-methyl levels in tomatoes sampled ...
Hematological changes of silver carp (hypophthalmichthys molitrix) in response to Diazinon pesticide
Diazinon is widely consumed for plague control in the agricultural farms and in domestic and aquaculture aspects. The present research purposed to evaluate the effect of half-lethal concentration (LC50) of diazinon on some biochemical and hematological parameters of silver carp, hypophthalmichthys molitrix, after 0, 24, 48 and 96 h. The results showed that the values of leukocytes (WBC), haemat...
The Columbia Center for Children's Environmental Health is using a combination of environmental and biologic measures to evaluate the effects of prenatal insecticide exposures among urban minorities in New York City. Of the 571 women enrolled, 85% report using some form of pest control during pregnancy and 46% report using exterminators, can sprays, and/or pest bombs. Chlorpyrifos, diazinon, an...
Hematological and biochemical changes were studied in beluga (Huso huso) weighing 450±50g in the presence of b,1-3, D-glucan as a single intraperitoneal injection (0.3mg/kg body weight) once, and thereafter a chronic exposure to organophosphate, diazinon at concentration of 1.5 mg/L as a continuous bath for 63 days at 22±1ºC. Results of erythrocyte profile in fish treat...
organophosphate insecticides such as diazinon are common to control pests in many agricultural fields that are located in the vicinity of fresh water resources. in this study male goldfish were exposed for 10 days at concentrations of 3 and 6 mg/ l diazinon (granules 10%) and after that histopathological effects of diazinon on some fish tissues were examined by light microscope. according this ...
the efficiency of diazinon (as insecticides) and nitrate (related to nitrogen fertilizer) removal from contaminated water is investigated through nf membrane technique. the effects of nitrate concentration (40-160 mg/l), diazinon concentration (10-1000 µg/l) and ph (5-9) on the efficiency of a commercial polyamide nanofilter membrane at a constant pressure of (800 kpa) are investigated. the res...
