The emission to the atmosphere of soil fumigants such as chloropicrin represents a potentially important human exposure pathway. Commonly, determining the air concentration of fumigants is carried out by pumping air through sorbent tubes which chemically retain the fumigant. In order to obtain an accurate measurement, it is essential that the fumigant does not break through the sorbent tubes, s...

OBJECTIVES Our objective was to examine the relationship between residential proximity to agricultural fumigant use and neurodevelopment in 7-year old children. METHODS Participants were living in the agricultural Salinas Valley, California and enrolled in the Center for the Health Assessment of Mothers and Children Of Salinas (CHAMACOS) study. We administered the Wechsler Intelligence Scale ...

The objective of the current study was to determine the chemical constituents and fumigant toxicity of the essential oil isolated by hydrodistillation form Juniperus foetidissima. The chemical composition of the essential oil was determined by GC and GC-MS. The essential oil included large amounts of monoterpenes 51.4%, with citronellol being the major compound thereof, and sesquiterpines 42.4%...

Background: Nowadays stored–product insect pests are controlled by pesticides and chemical fumigant compounds. The continueous use of chemical pesticides is harmful for non–target creatures specially humans and other mammals. Beside they polluted the environment. Objective: Accoring to the studies, the essential oil of Labiatae plants have insecticidal activity against some pests. In this st...

Dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of Aedes aegypti (L.), the primary vector in the tropical and semitropical world. With no available vaccine, controlling the dengue vector is essential to avoid epidemics. This study evaluates the efficacy of a new smoke-generating formulation containing pyriproxyfen and permethrin in Puert...

A simple and reliable method using on-line purge and trap gas chromatography mass spectrometry has been developed for the determination of the fumigant 1,3-dichloropropene (1,3-DCP) in agricultural water and soil samples. The proposed analytical methodology was validated in the target environmental matrices by the analysis of spiked blank matrix samples. Limit of detection values of 0.05 microg...
