Background: Paraquat is a herbicide with a good occupational safety record, but a high mortality after intentional ingestion that has proved refractory to treatment. For nearly three decades paraquat concentrationtime data have been used to predict t

Mevalonic acid in urine is converted to its lactone form by incubation overnight at acidic pH, extracted and analysed by GC-MS. The lower limit of quantitation of 7.5 ng/ml provides adequate sensitivity to measure changes in urinary excretion of MVA

Two groups of three male volunteers were exposed to atmospheric concentrations of either 327 or 1833 mg m-3 chlorodifluoromethane (HCFC22) for 4 h. Blood, urine and expired air samples were taken during and after the exposure period and analysed for

1. The pyrethroid insecticide cypermethrin was administered orally to six male volunteers as a single dose of 3.3 mg (cis: trans 1:1) and dermally to six volunteers at a dose of 31 mg/800 cm2 (cis:trans 56:44) as a soya oil-based formulation. Urine s

A physiologically based mathematical model is described for the human inhalation pharmacokinetics of 1,1,2-trichloro-1,2,2-trifluoroethane (FC113). Physiological parameters for the model are derived from the scientific literature. Partition coefficie

Seven male volunteers were exposed to atmospheric concentrations of either 1980, 4100 or 7630 mg m-3 1,1,2-trichloro-1,2,2-trifluoroethane (FC113) for 4 h. Blood and expired air samples were collected during the exposure period and for several days s

We studied the effects of three vehicles (propylene glycol, octanol and ethyl decanoate) with differing polarity on the in vitro percutaneous absorption of three chemicals (fluazifop-butyl, dimethyl phthalate and fomesafen sodium salt) with a range o

A simple method is described for the analysis of mevalonic acid (MVA) in human urine involving conversion to MVA lactone (MVAL) and determination by GC-MS. A strategy is described to achieve a low limit of quantitation to overcome the constraint that

This paper reviews the development of biological monitoring as a method of assessing absorption of pesticides during occupational exposure. An approach to human volunteer studies to estimate the relationship between exposure to pesticides and excreti
