Abstracts to Forthcoming Papers

THE MICRODETERMINATION OF MERCURY ANDORGANOMERCURY COMPOUNDS IN ENVIRONMENTALMATERIALS

J. F. Uthe and F. A. J. Armstrong, Dept. of the Environment, FisheriesResearch Board of Canada, Freshwater Institute, Winnipeg, Manitoba.

In this review, current methods used for analysis of mercury at a part-per-million level inenvironmental samples are studied, but it will mainly centre around the use of atomicabsorption spectro-photometry (AAS) for the determination of total mercury content andthe use of gas chromatographic methods for determination of methyl mercury.

THE BOLL WEEVIL-COTTON PLANT COMPLEX

P. A. Hedin, A. C. Thompson and R. C. Gueldner, USDA, Boll WeevilResearch Laboratory, Entomology Research Division, State College,Mississippi, U.S.A.

The boll weevil, Anthonomos Grandis Boheman was introduced from Mexico into theUnited States about 1892. More than three-fourths of all insect losses to cotton in thiscountry have been attributed to this insect, and it is generally agreed that cotton cannot beprofitably grown in areas where it occurs without adequate control measures. This reviewsummarizes the chemically oriented research conducted on this plant-insect complex duringthe past seventy years with emphasis on the program conducted since 1962 at the BollWeevil Research Laboratory.

Of plant-insect relationships, host plant resistance, feeding stimulants, plant attractants,and plant constituents are discussed. Insect-insect relationships treated include insecticides,chemosterilants and hormones, sex attractants, and insect constituents. The development ofan integrated program for the attempted eradication of this insect is also discussed.

USE OF MERCURY IN AGRICULTURE AND ITS RELATIONSHIPTO ENVIRONMENTAL POLLUTION

J. G. Saha and K. S. McKinlay, Canada Agriculture Research Station,Saskatoon, Saskatchewan, Canada.

The agricultural use of mercury has been the origin of considerable concern and althoughsome of the criticism has been justifiable, much of it has been without any scientific basisat all. The present review attempts to make a realistic assessment of the risks involved in theagricultural use of mercury. In order to put the problem in perspective, however, one mustalso consider the natural occurrence of mercury in the environment and the changes broughtabout by other human activities.
