In order to ensure edible safety, more regard has been paid to pesticide contamination on agricultural product. Conventional techniques are used to measure pesticide contamination. However, the conventional analyses are not possible because of their destructive characteristic and the limitation of time and labor. Spectral technique can provide a rapid, nondestructive means to assess quality and...

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...

Subacute experiments were carried out on rabbits by daily oral administration of Lindane, Malathion and Dichlorophos. A dose-dependent significant decrease in Salmonella typhi induced immune response was found in sera of animals treated with these pesticides compared to untreated controls. Inihbition of cholinesterase activity confirmed the immunological findings.
