Potential hazards of fumigant residues.
A spectrum of fumigants (primarily ethylene dibromide, 1,2-dibromo-3-chloropropane, ethylene oxide, symdibromotetetrachloroethane, 1,3-dichloropropene, dichlorovos, carbon tetrachloride, methyl bromide) as well as their degradation products in foodstuffs and soil have been examined mainly in regard to the potential mutagenicity of their residues.
متن کاملLeaching potential of persistent soil fumigant residues.
Persistent fumigant residues in soil resulting from agricultural pest-control practices may be released into water and leached to groundwater. In this study, the leaching potential of persistent soil fumigant residues was evaluated, and the effect of dissolved organic matter (DOM) and ammonium thiosulfate (ATS) amendment was investigated. A silt loam soil was incubated separately with the fumig...
متن کاملFormation and extraction of persistent fumigant residues in soils.
Fumigants are commonly thought to be short-lived in soil, but residues have been found in soils years following application. In this study, formation and extraction of persistent soil fumigant residues were investigated. Fumigants 1,3-dichloropropene (1,3-D), chloropicrin (CP), and methyl isothiocyanate (MITC) were spiked into Arlington, Glenelg, and Hagerstown soils and incubated for 30 d unde...
متن کاملUltrasound treatment acceleration of solvent extraction for fumigant residues from wheat.
Concerns about consumer and worker safety and the fate of fumigants have fuelled strong efforts to determine their residues in foodstuffs. Fumigants are usually extracted from commodities with solvent at room temperature (25 degrees C). In this paper, solvent extraction of methyl bromide, phosphine, carbonyl sulfide, and carbon disulfide using ultrasonic acceleration or heating was evaluated. W...
متن کاملCardiovascular effects of potential occupational hazards.
Cardiovascular effects of potential occupational hazards have received relatively little attention. The major inhalant occupational exposures of concern are carbon disulfide, nitrates, halogenated hydrocarbons and carbon dioxide. Occupational exposure to certain trace metals may also be associated with adverse cardiovascular effects. Of concern is potential toxicity from cobalt, antimony, lead,...
