549 •RESULTS The distribution of radioactiv:j.t-y in the top four inches of soil four months after a 6 H/Atreatment of c.I4Wben can be seen in Graph I. It is to be noted1ihat the h~8t concentrati6ft otradioactivity is f~ in the layer of soil 1/8 n to 1/4"below the soU surface. From that point on there is a gradual decline in radioactivity. Direct counting of untreated soil1ll1der the S8itte conditi 9lUl.yields an avera~\ of 13 counts pprmin .. uiiF of above background due 1;0 the 'natura~ oceurring~:loactivity K40•. The lOll'.' counts received therefore, frcllIl'the 3" to 4n 1~ are still greater than that received !rom the untreated soil·. ,", ' •. '.f The comparison in dil.8Wi1bution of racH\iiactivity between the 3 H/A treatment and the 6 HI! is shown in Graph II. 'iIill*el/2 1t soil layers were collected and counted d1rec~.Obviouslt one~s pot obtain as quite a clear picture of the radioactive distributionwh1jft l/2 11 layers are oounted as compared to 1/8 11 layers. The olose similaritj/:ln oounts reoeivedbe'tween the 3 H/Aand 6 H/Atreatments is undejItandable,e1nce both applications contained exactly the same amount of C Wben.\.:.I£ Graph II had pl',en drawn to show the total amount of Wben for each 18i181"'- instead of the Cllf fraction then the relative length of the bars for the 3 HtArate would be twice as long as indicated while the bars for the 6 H/Arate would be four t:iJlles as long. . Of the various chemical procedures tried a barium hydroxide digestion was the most efficient in remov:lng t.he radioactive components from the soil. The choice of this partioular alkali was based upon the work oonducted by Ercegovich in reoovering Amitrole from the soil. (2) Table I is a summary of the results of analyses of the various soil layers using the barium hydroxide digestion. In each case only a part of the radioactivity is removed. For inste,nce the alkaline digestion of SOgramsof soil from the 0-1/2 11 layer only decreased the counts from 4S7clmto 29Sclin. This drop of 162 clm from the so11 surface represents a recovery of' 62,420 clin in the purified extracts. Dy plotting the recovery data in Table I from the various layers of soil it is possible to approximate the total amount of radioaotivity present in the soil. If one ass1.lJll8Sthat all of the radioactivity in the top four inohes of soil is Amiben then this would account for approx :iJllately 17% of the Wben that was originally applied. Paper ohromatography was used to examine the alkaline digests "to determine how much of the recovered radioactivity could be attributed to Amiben. Examination of the Rf values in Table I indicates that the aotivity reo overed from the lower two layers was not Amiben. It may be a complex of Amiben that is stable to the alkaline digestion used or poss;\.Ply an entirely different oompound synthesiZed by soil o!'ganisms utilizing C14 from Wben. ,\ .
