Identification of degradation products of the avicide 3-chloro-para-toluidine hydrochloride in Louisiana rice fields
Article Abstract:
A comprehensive study on the migration of 3-chloro-para-toluidine hydrochloride (CPTH) on treated rice baits to soils in Louisiana rice fields is presented. The soils were tested, with the use of field and laboratory studies, for traces of free CPTH and their degradation products. The utilization of gas chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS) allowed the easy identification of CPTH products.

Effect of exposure to chlorobenzenes on growth rates of the crab Portunus pelagicus (L)
Article Abstract:
Juvenile crabs of the genus Portunus pelagicus were exposed to different types of chlorobenzenes to determine the impact of the chemicals on their growth rate. The results showed that extended exposure to chlorobenzene concentrations which were less than acutely toxic caused a reduction in the growth rates of the crustaceans. Critical body residue concentrations of the toxicant decreased along with molecular weight.

High-speed isothermal analysis of atmospheric isoprene and DMS using on-line two-dimensional gas chromatography
Article Abstract:
An instrument consisting of a programmed temperature vaporization injector and a two-dimensional gas chromatography system enables the quick measurement of dimethyl sulfide and isoprene concentrations. This ability to make a quick measurement is particularly important with isoprene because the compound readily breaks down within 10 to 15 minutes in the presence of high concentrations of OH.
