OBJECTIVE Organophosphorus (OP) pesticides are considered hazardous substances because of their high toxicity to nontarget species and their persistence in the environment and agricultural products. Therefore, it is important to develop a rapid, sensitive, and economical method for detecting OP pesticides and their residues in food and the environment. METHODS A broad, selective monoclonal an...

The mode of action of pesticides is extremely fascinating because the subject covers so many fields of biology and chemistry and has many practical implications. To understand how pesticides work (their mode of action), it is necessary to understand how the pests’ targeted systems normally function. It is also helpful to understand how human systems function in order to see similarities and dif...

BACKGROUND Persistent organic pollutants represent about 95 % of the industrial sector effluents in Egypt. Contamination of the River Nile water with various pesticides poses a hazardous risk to both human and environmental compartments. Therefore, a large scale monitoring study was carried on pesticides pollution in three geographical main regions along the River Nil water stream, Egypt. MET...

exposure to pesticides could be one of the contributing cause to the falling sperm counts and rising levels of male infertility. adverse effects of pesticides in the environment first received widespread attention in the 1960s. however, only recently it has been postulated that long term, low exposure of these chemicals are increasingly linked to human health effects such as immuno-suppression,...

Background: Organophosphorus pesticides are widely used in agriculture, homes, gardens, and veterinary practices. Extensive application of pesticides in agriculture often results in residues of these compounds being absorbed into the foods, including wheat. The aim of this study was to evaluate the residue levels of 20 organophosphorus pesticides in wheat samples collected from different region...

Adsorption isotherms of 10 pesticides and their biodegradation intermediates on clay minerals and soils were investigated to predict the fate of pesticides in the environment. The adsorption isotherms were expressed by the Freundlich isotherm equation. Pentachloronitrobenzene, 2,4,6-trichlorophenyl-4′-nitrophenylether, and various intermediates were highly adsorbed on soils, although isoprothio...

Pesticide use has been the mainstay control of disease vectors and pests of importance to public health [1–3]. However, three recent developments have raised concern over how pesticides used for public health (which include vector-control pesticides, household insecticides, and professional pest-management pesticides [4]), are being regulated, managed, and monitored in affected countries. Distu...

The Eastern Mediterranean Region is facing an increasing burden of vector-borne diseases. Progress in controlling these disease is compromised by the limited number of vector control interventions, most of which rely on the use of pesticides. The lack of new pesticides under development and the spread of vector resistance necessitate judicious use of existing pesticides to preserve their public...
