Poly(dimethylsiloxane) (PDMS) and a poly(DMS-styrene) block copolymer were compared as extraction and optical detection media for hydrophobic compounds in water and water/ethanol solutions. Partitioning to both polymers increased exponentially with i

The focus of this research was on elucidation of the role of deciduous tree ecosystems in accumulation of fine-particle-associated polycyclic aromatic hydrocarbons (PAHs) and heavy metals on leaves of deciduous trees. The studied species were Tilia x

Mirex is a toxic, hydrophobic pollutant in Lake Ontario that undergoes an indirect photoreaction mediated by natural dissolved organic matter. The monohydro product photomirex further photolyzes to form a dihydro product. The efficiency of mirex phot

Photolytic rate constants for the novel energetic compoundammonium dinitramide(ADNweredetermined in order to understand the fate of ADN in natural bodies of water. Quantum yields were measured between 290 and 400 nm using a lamp system, and these val

The hydrophobic chlorocarbon mirex readily binds to aqueous humic acids (HAs). In HA solutions irradiated at sunlight wavelengths (λ ≥ 290 nm), mirex molecules bound to HAs are transformed to photomirex by dechlorination. The mechanism of this int

A kinetic model was developed describing the effects of hydrophobic partitioning to humics on second-order humic-mediated photoreactions in aqueous solution. Model development and evaluation were in terms of the humic-mediated dechlorination of the h

A mass balance approach was used to evaluate the fate of mirex in the Oswego River. The objectives of this research were 1) to assess the magnitude and extent of mirex contamination in the Oswego River, 2) to quantify the transport, fate, and distrib

Dissolved hydrophobic chemicals can be concentrated with a passive, in situ concentration-extraction sampler (PISCES), an inexpensive and easy-to-use device made from plumbing parts and polyethylene film. PISCES is intended to mimic the direct uptake
