Due to the great amount of pesticides currently being used, there is an increased interest for developing biosensors for their detection. Among all the physical transducers, piezoelectric systems have emerged as the most attractive due to their simplicity, low instrumentation costs, possibility for real-time and label-free detection and generally high sensitivity. This paper presents an overvie...

Increase in the population of India, results in higher demand for food as well as decrease in land for farming. Hence to fulfil the increased demand, food is adulterated to get more quantity in short period of time. Moreover, pesticides in crops are using above the legal maximum residue limit by farmers to gain more profit in lesser time. Although pesticides are highly effective on pests but th...

BACKGROUND Pesticide exposure may be positively associated with depression. Few previous studies have considered the episodic nature of depression or examined individual pesticides. OBJECTIVE We evaluated associations between pesticide exposure and depression among male private pesticide applicators in the Agricultural Health Study. METHODS We analyzed data for 10 pesticide classes and 50 s...

This study characterized the within- and between-child variability in dimethylthiophosphate (DMTP) levels in the urine of 44 children living in an agricultural community in central Washington State in December 1997 and 1999. The goal of this analysis was to investigate these variability components during periods when organophosphate pesticides were and were not actively applied to orchards in t...

chlorpyrifos is one of the organophosphate pesticides that are commonly used to control insects in domestic activities and many agricultural farms that are located in close to water sources. hence, the present study, investigate the lethal toxicity of this pesticide. in this study, fish were treated in groups of 21 with different concentrations of chlorpyrifos (aria brand with active ingredient...

The acute nervous system toxicity of organophosphate (OP) pesticides is well described. However, the reported long-term effects of OP pesticides on the nervous system are inconsistent. This inconsistency may be due to imprecise estimates of pesticide exposure, variability of central nervous system (CNS) and peripheral nervous system (PNS) assessment, small samples, and poor control of confoundi...

BACKGROUND Organophosphate poisoning is a major public health problem in South Africa. Individuals get exposed to organophosphate in both the domestic and industrial spheres. METHOD A cross-sectional study was conducted using retrospective, secondary data of organophosphate poisoning cases over a 3-year period, reported at the Tshwane District surveillance office. Data were analysed using Mic...

The effect on fecundity of two organophosphates, chlorpyrifos and diazinon, was assessed in the earthworm Aporrectodea caliginosa. Juveniles were exposed to two sub-lethal concentrations of each organophosphate, the lowest of which was a laboratory-simulated field rate, for 4 weeks and recovery was monitored for 12 weeks in organophosphate-free soil. Growth, maturation, cocoon production and ha...
