In the present study, the residual pesticide levels were determined in eggplants (Solanum melongena) (n = 16), purchased from four different markets in Dhaka, Bangladesh. The carbamate and organophosphorus pesticide residual levels were determined by high performance liquid chromatography (HPLC), and the efficiency of gamma radiation on pesticide removal in three different types of vegetables w...

Chiu and her colleagues from Harvard School of Public Health and Massachusetts General Hospital present important new data on semen quality in relation to dietary pesticide exposure via fruit and vegetable intake (Chiu et al., 2015). To examine this relationship the authors utilized a novel approach that classifies fruits and vegetables into high versus low-to-moderate pesticide residue groups ...

Compared with conventional methods, electrochemical immunosensors have many advantages, such as low cost, high sensitivity, and rapid detection, and has certain prospects for realizing real-time-monitoring. In this paper, a design of portable pesticide residues detection instrument was presented based on an electrochemical impedance immunosensor. Firstly, we studied on an impedance immunosensor...

A validation study was conducted on a rapid multiresidue method for determination of pesticide residues in vegetables and fruits by LC-MS/MS. Pesticide residues in the vegetables or fruits were extracted with acetonitrile in a disposable tube using a homogenizer, followed by salting out with anhydrous magnesium sulfate and sodium chloride in the presence of citrate salts for buffering. The extr...

Beekeepers who use honey bees (Apis mellifera L.) for crop pollination services, or have colonies making honey on or in close proximity to agricultural crops, are concerned about the reductions of colony foragers and ultimate weakening of their colonies. Pesticide exposure is a potential factor in the loss of foragers. During 2009-2010, we assessed changes in the field force populations of 9-10...

Abstract Background A method is now available to quantify the number of pesticide residues and relative dietary risks in individual servings food. The Dietary Risk Index (DRI) system combines results United States Kingdom residue testing programs with data on food serving sizes each pesticide’s chronic Reference Dose or Acceptable Daily Intake. Chronic DRI values are a ratio: amount maximum all...

Vegetables constitute an important component of a balanced diet. Being a rich source of vitamins and minerals, they protect us from micronutrient deficiencies and gastrointestinal disturbances. However, along with life-saving nutrients, they have turned into a major source of life-taking poisonous substances called pesticides and their residues into the human body. Many studies reviewed across ...

Vegetables are rich sources of vitamins, minerals, and fibers, and have beneficial antioxidative effects. Ingestion of vegetables containing pesticides is one of the main routes through which these enter the human body. Slowly released into the body, however, pesticides can cause an array of diseases. In this study we investigated the concentrations of some pesticides in the most frequently con...

The identification of herbicide residues on crop foliage is necessary to make crop-management decisions for weed pest control and to monitor pesticide residue levels on food crops. Electronic-nose (e-nose) methods were tested as a cheaper, alternative means of discriminating between herbicide residue types (compared with conventional chromatography methods), by detection of headspace volatiles ...
