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...

Background and purpose: Pesticides cause general concern due to their possible adverse results on human health. The aim of this study was to investigate different pesticides and also estimating daily intake of their residues in melon and watermelon samples in Kashan, Iran. Materials and methods: In this cross-sectional study, 62 melon and watermelon samples were collected from different fruit ...

In current study, the effects of Iranian rice cooking method (Kateh) on residue levels of 41 pesticides were investigated. The pesticides were selected according to Iranian National Standards Organization (INSO) regulations and covered 18 permitted and 23 banned pesticides belonging to different chemical classes such as organophosphate, triazole, and carbamate. A 250 g portion of rice sample wa...

In this paper the efficiency of a method for the separation and identification of pesticides in lanolin is presented. Theses pesticides belong to the organophosphorous and synthetic pyrethroids families. After the gel permeation chromatography, pesticides are separated from lanolin into two fractions corresponding to the two families, which simplify subsequent analysis by gas chromatography.

A gas chromatography mass spectrometry with spike calibration curve method was used to quantify three carbamate pesticides residue in cooked white rice and to estimate the reduction percentage of the cooking process duration. The selected pesticides are three carbamate pesticides including carbaryl and pirimicarb that their MRL is issued by “The Institute of Standards of Iran” and propoxur whic...

Executive Summary The NMDOH developed conclusions and recommendations about the potential association of pesticide exposure and Parkinson's disease (PD) based on the literature assessed. Two main categories were analyzed: studies without genetic interactions and studies with genetic interactions. Within these two categories, the following categories of pesticides were identified: 1) general, 2)...

An application of large quantity of agricultural pesticides in rural area is a common practice in order to increase the productivity and yield, to protect the agricultural crop from pests and prevent products lost due to insect and bacterial contamination is a common practice. Resistance and mutation of some pests to chemicals are the causes of using larger quantity of pesticide in the developi...

Evidence continues to accumulate that pesticides are the leading candidates of environmental toxins that may contribute to the pathogenesis of Parkinson's disease. The mechanisms, however, remain largely unclear. According to epidemiological studies, we selected nine representative pesticides (paraquat, rotenone, chlorpyrifos, pendimethalin, endosulfan, fenpyroximate, tebufenpyrad, trichlorphon...
