Absorption, Translocation And Metabolism Of 1,3-Dichloropropene In Selected Plants, David L. Berry
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The absorption, translocation and metabolism of 1,3-dichloropropene (a soil fumigant) in bush beans, tomato and carrot was studied under growth chamber and greenhouse conditions using solution culture, vermiculite and sand. Absorption was monitored using gas chromatographic analysis and isotope techniques. Plants were shown to absorb a maximum amount of dichloropropene by 24 to 48 hr from solution culture and vermiculite. The plant absorbed and translocated 1,3-dichlorpropene-14C-U readily to aerial parts of the plant.
Bush beans, tomatoes and carrots absorbed and translocated 3-chlorallyl alcohol-14C-U from solution culture and vermiculite. Levels of 3-chloroallyl alcohol reached maximum at 24 …
Mercury, Dieldrin, Ddt, Dde, And Pcb Levels In Tissues From Fish And Wildlife In Utah, Fred A. Smith
Mercury, Dieldrin, Ddt, Dde, And Pcb Levels In Tissues From Fish And Wildlife In Utah, Fred A. Smith
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Fish and wildlife were randomly sampled in Utah from pre-selected x areas and analyzed for levels of total mercury, dieldrin, DDT, and DDE. Levels were well within consumptive tolerance or guideline limits except for mercury levels of fish in Willard Bay Reservoir. PCB's were also identified in a large proportion of samples.
None of the chukars, 6 percent of the pheasants, 4 percent of the waterfowl, and none of the fish sampled, excluding Willard Bay Reservoir, were above the 0.5 ppm guideline level for mercury established by the Food and Drug Administration. Seventy-seven percent of the fish sampled from Willard …
