Common carp (Cyprinus carpio) is an important aquaculture species. However, their production and health sometimes threatened by pesticides. In common carp, extensive studies have been done for exposures of single pesticides, but effects mixtures such as those the commonly used chlorpyrifos dichlorvos, are still unknown this first phase work, acute lethal exposure experiment was conducted to est...

Acetylcholinesterase resistance has been well documented in many insects, including several mosquito species. We tested the resistance of five wild, Chinese strains of the mosquito Culex pipiens quinquefasciatus to two kinds of pesticides, dichlorvos and propoxur. An acetylcholinesterase gene (ace1) was cloned and sequenced from a pooled sample of mosquitoes from these five strains and the amin...

Parental exposure to pesticides may contribute to childhood cancer risk. Through the Agricultural Health Study, a prospective study of pesticide applicators in Iowa and North Carolina, we examined childhood cancer risk and associations with parental pesticide application. Identifying information for 17,357 children of Iowa pesticide applicators was provided by parents via questionnaires (1993-1...

The study analyzed the effects of pesticides on selected vegetable crops grown in Abakaliki, Ebonyi State Nigeria. pesticide Dichlorvos (DD Force) was used to treat sites planted with Amaranth, cucumber, and okra. Soil samples were randomly collected after 30 days incorporation tested for traces chloride phosphate. results analysis showed that amaranth, okra residue concentration exceeded maxim...

BACKGROUND A wide range of pesticides is applied for crop protection in vegetable cultivation in China. Regulation of pesticide maximum residue limits (MRLs) in vegetables is established but not fully enforced. And pesticide residues in vegetables were not well monitored. This study conducted the monitoring surveys from 2011 to 2013 to investigate the pesticides in vegetables in the northwest r...

Molecular Imprinted Polymers (MIPs) have been used for recognition and binding of different compounds. We are developing MIPs to selectively bind organophosphate pesticides and toxic chemical warfare nerve agents. MIPs were made to the pesticide Dichlorvos. Control MIPs were made without the template. Dichlorvos-MIPs bound more Dichlorvos in comparison to control-MIPs. The Dichlorvos-MIPs can b...

The extensive use of pesticides leads to accumulation of a huge amount of residues in the environment. As such, the present study investigates the potentiality of Pleurotus pulmonarius to bioremediate dichlorvos pesticides (2,2-dichlorovinyldimethylphosphate) in contaminated soil. DDVP-polluted soils have been contaminated in five concentrations (5% v/w, 10% v/w, 15% v/w, 20% v/w, and 25% v/w),...

The presence of organophosphate pesticides could inhibit the activity alpha-naphthyl acetate esterase (ANAE), which use as fundamental for biosensor applications. k-carrageenan was used immobilization ANAE extracted from wheat-based sources. free and immobilized assessed optimum at a range temperature pH. Enzyme kinetic studies were performed using Michaelis-Menten parameters Lineweaver-Burk, L...
