Biological monitoring for selected herbicide biomarkers in the urine of exposed custom applicators: application of mixed-effect models.
Metabolites and/or parent compounds of the herbicides atrazine, alachlor, metolachlor, cyanazine and the 2-ethylhexyl ester of 2,4-dichlorophenoxyacetic acid (2,4-D) were measured in the urine of 15Expand
Evaluation of irritancy and sensitization potential of metalworking fluid mixtures and components
There are approximately 1.2 million workers exposed to metalworking fluids (MWF), which are used to reduce the heat and friction associated with industrial machining and grinding operations.Expand
A Biological Monitoring Method for o-Toluidine and Aniline in Urine Using High Performance Liquid Chromatography with Electrochemical Detection
Abstract A urinalysis method for o-toluidine and aniline was developed for biological monitoring. Urine specimens were made 4.7 M in sodium hydroxide and heated at 80°C for 2 hours to convert theExpand
Synthesis, characterization, and use of 2-[(2H9)butoxy]acetic acid and 2-(3-methylbutoxy)acetic acid as an internal standard and an instrument performance surrogate, respectively, for the gas
Abstract 2-[(2H9)Butoxy]acetic acid and 2-(3-methylbutoxy)acetic acid were synthesized, mixed with 2-butoxyacetic acid, and separated by capillary gas chromatography on a fused-silica column with aExpand
Quantitation of trace levels of phenyltin compounds using HPTLC
Mixtures of tetraphenyltin, triphenyltin chloride, diphenyltin dichloride, and monophenyltin trichloride were resolved using high performance thin layer chromatography on silica gel with retentionExpand
High-Performance Liquid Chromatography Identification, Quantification, and Fractionation of a Suspect Allergen, 4-Chloro-3-methylphenol, in an LLNA-Positive Metalworking Fluid
A metalworking fluid (MWF) was obtained that produced an allergic reaction in the local lymph node assay (LLNA) with an EC3 = 4%, the EC3 being the estimated concentration needed to provoke a 3-foldExpand
Robotic direct reading device with spatial, temporal, and PID sensors for laboratory VOC exposure assessment
TLDR
We evaluated a novel robotic direct reading method that used a real-time location system to measure the spatial-concentration distribution of volatile organic compounds (VOCs) in a chemistry laboratory. Expand
Assessing flammable storage cabinets as sources of VOC exposure in laboratories using real-time direct reading wireless detectors
Herein we present the results of measurements using wireless direct-reading photoionization detector-based gas sensors to quantify concentrations of vapors of volatile organic compounds (VOCs) in andExpand
Synthesis, characterization, and use of 2-[(2H(9))butoxy]acetic acid and 2-(3-methylbutoxy)acetic acid as an internal standard and an instrument performance surrogate, respectively, for the gas
2-[(2H(9))Butoxy]acetic acid and 2-(3-methylbutoxy)acetic acid were synthesized, mixed with 2-butoxyacetic acid, and separated by capillary gas chromatography on a fused-silica column with a lengthExpand
