“…Information relating the uptake of DDT to its distribution within the plant was lacking and it was essential to establish to what extent and where the pesticide accumulates. The presence of various degradation products of DDT in tobacco (Chopra et al 1970), their'possible association with health hazards, and the requirements for reduced total DDT levels in export tobacco (Anonymous 1966;Guthrie 1972) require continued studies of the presence of DDT in tobacco. This is a report on the distribution of DDT-*C (phenyl-rinS') [403][404][405][406][407] (Apr.…”

Rose, Nr,sron eNo CnrNc, H. H, 1974. Distribution of DDT-uC inNicotiana tabacum. Can. J. Plant Sci. 54: 403-407. Tobacco, Nicotiana tabacum L., when grown in aerated nutrient solution, quartz sand or field soil, took up p,p'-DDT from the medium. The major portion of the total DDT in the plant was located in the root although the stem portions of the plant also accumulated the pesticide. The distribution of DDT varied within the shoot portion, with the largest concentration being in the lower leaves of the plant.When the DDT in the shoot was expressed in quantity (pg DDT per sample), the leaves of mid-stalk insertion contained the most DDT.

+ ions of some methyl-6-deoxy-6-bromo-a-D-glucopyranoside derivatives are discussed. Elimination of MeOH resulting in the glycosidyl cation is the predominant reaction of the [ M + HI+ ion. This process is completely suppressed during CID of the metal-cationized species, which, surprisingly, show elimination of the added metal in the form of RC00-metal and metal bromide in the case of the ester derivatives. These reactions appear to be assisted by neighbouring group participation. Because of the proximity of the C(3)-oxygen with C(6), the benzyl ether derivative is characterized by the loss of PhCH,Br from the IM + metal] + ion.
