PURPOSE Branch Simazine and diuron are herbicides that have been found in surface and ground water in California. Because they have traditionally been used on highway rights-of-way during the rainy season, this is a potential source of surface and ground water pollution. The Department of Pesticide Regulation (DPR), which is responsible for preventing(More)
Overview The Department of Pesticide Regulation (DPR) is establishing a network to sample ambient air for multiple pesticides in several communities. DPR will sample on a regular schedule over three or more years and use the data to evaluate health risk and, as necessary, improve protective measures against pesticide exposure. DPR expects to begin the(More)

The objective of this study was to investigate the extent to which precipitation affects the mobility of pesticides in a sandy loam soil which received no additional irrigation. During a four month period, 172 mm of rain fell on the experimental plots to which ordram, simazine and carbofuran had been applied at a rate of O.OOlkg active ingredient mm2. A(More)

Aerial application of baited malathion has been used in recent Mediterranean Fruit Fly Eradication Programs in California in 1981 and 1989/90. In response to public concerns about exposure to malathion from this method of application, the California Department of Health Services (CDHS) conducted exposure assessment studies and concluded that a potential(More)
—Long period gratings (LPGs) were written into a D-shaped single-mode fiber. These LPGs were subjected to a range of curvatures, and it was found that as curvature increased, there was increasingly strong coupling to certain higher order cladding modes without the usual splitting of the LPGs stop-bands. A bend-induced stopband yielded a spectral sensitivity(More)
