The first version, prepared by the United Nations Economic and Social Council's Committee of Experts on the Transport of Dangerous Goods, was published in 1956 (ST/ECA/43-E/CN.2/170). In response to developments in technology and the changing needs of users, they have been regularly amended and updated at succeeding sessions of the Committee of Experts pursuant to Resolution 645 G (XXIII) of 26 April 1957 of the Economic and Social Council and subsequent resolutions. -
The Calcium Arsenates

ROBINSON Acting Chemist, Oregon Agricultural Experiment Station. CORVALLIS, OREGON The regular huIlejne of the Station are sent free to the residents of Oregon who request them. THE CALCIUM ARSENATES By R. H. ROBINSON Acting Chemist, Oregon Agricultural Experiment Station INTRODUCTION Chemical investigations on the calcium arsenates relative to their economfic value and practicability as insecticides have been carried on by the department of Agricultural Chemistry of this Station during the past two years.The results obtained from these investigations are presented in this bulletin.The work was supported by the annual funds provided by the Adams Act of the United States Government.. Commercial calcium arsenate is an arsenical now being produced by reliable manufacturers of spray material and offered for sale as a sub- stitute for the arsenates of lead.The value of the latter as a stomachic insecticide has been demonstrated, and itis now used extensively for the successful controlof the codling moth, the destructionof the cotton boll worm., the tobacco worm, and the Colorado potato beetle. Previous inveatigations on the toxic values and killing power of calcium arsenate and lead arsenate indicate equal efficiency. A consideration of a few figures will show the economic advantages which might be gained if calcium arsenate could be substituted for lead arsenate.A conservative estimate of the quantity of lead arsenate used annually in the United States, as stated by one of the largest manufac- turers of spray materials, is probably more than 30,000,000 pounds. -
