Occupational health and safety in household hazardous waste management facilities.
Employees in household hazardous waste management facilities encounter a variety of potentially hazardous exposures. The purpose of this study was to evaluate both chemical and physical hazards at a representative group of household hazardous waste management facilities in Minnesota. Sampling results...
Multiclass determination of 66 organic micropollutants in environmental water samples by fast gas chromatography-mass spectrometry.
A multiresidue method has been developed for quantification and identification of 66 multiclass priority organic pollutants in water by fast gas chromatography (GC) coupled to mass spectrometry (MS). Capabilities and limitations of single quadrupole mass spectrometer as detector in f...
Using gas chromatography to characterize a direct coal liquefaction naphtha.
Speciation of oxygenated compounds in direct coal liquefaction naphthas is essential considering their important roles in coal conversion reactions. This study attempts to characterize them as fully as possible using gas chromatographic systems. Firstly, GC-MS was deployed allowing t...
Mapping the nanoparticle-coating monolayer with NMR pseudocontact shifts.
Lanthanide ions Yb(3+) and Tb(3+), once bound to the monolayer of organic molecules coating the surface of gold nanoparticles, induce pseudo-contact shifts on the signals of nearby nuclear spins. This not only allows the investigation of the average structure of the ligands in the mo...
Estrogenic effects of dissolved organic matter and its impact on the activity of 17β-estradiol.
We always think, and the hormone-like effects of DOM have been reported. The objective of this study was to investigate the estrogenic effects of DOM and its impact on the activity of the natural estrogen 17β-estradiol (E2). DOM of three different sources, HA sodium salt, Suwannee R...
Molecular solids: Co-crystals give light a tune-up.
Highly luminescent metal-organic frameworks through quantum dot doping.
The incorporation of highly luminescent core-shell quantum dots (QDs) within a metal-organic framework (MOF) is achieved through a one-pot method. Through appropriate surface functionalization, the QDs are solubilized within MOF-5 growth media. This permits the incorporation of the Q...
Psychophysical evaluation of achromatic and chromatic vision of workers chronically exposed to organic solvents.
The purpose of this paper was to evaluate achromatic and chromatic vision of workers chronically exposed to organic solvents through psychophysical methods. Thirty-one gas station workers (31.5 ± 8.4 years old) were evaluated. Psychophysical tests were achromatic tests (Snellen char...
Molecular monolayers as semiconducting channels in field effect transistors.
This chapter describes the fundamental study of charge transport through single layers of π-conjugated molecules organized to form the semiconducting channels of field-effect transistors (FETs). Physical and chemical methods of evaporation, Langmuir-Blodgett assembly and transfer, a...
Assimilable organic carbon (AOC) in soil water extracts using Vibrio harveyi BB721 and its implication for microbial biomass.
Our data showed that AOC levels in soil water extracts were significantly correlated (P<0.05) with microbial biomass determined as microbial biomass carbon, indicating that the AOC concentrations determined by the method developed might be a good indicator of soil microbial biomass. Our findings pro...
