C. ruhmeiscer Technical Services Superintendent. Monsanto Chemical Company Anniston, Alabama 36202 ' Dear Mr. Euhmeiscer: The following is a brief report of our activities - in August. srrA September, excluding the information contained in my letter of September 19, 1966: . 1) The sample of 551? provided by Monsanto was used' in preliminary tests to determine its toxicity to bluegills (levonis macrochlrus). Specimens measuring 1.5 to. 2.0 inches.in length were exposed in concentrations up to 1000 ppb at room temperature (72 i 2 F). All fish survived. Pit? in relatively non-toxic compared with . insecticides. " 2) Previously, we reported tentative 36-nr TLffl values for bluegills to be about 25 ppb for methyl parathion and about 75- ppb for ethyl parathion. Additional tests have confirmed the .25 ppb value for methyl parathion but . indicate that Che parathion value may be' closer to 65 ppb. Although these points may be further refined, I am confident that they are accurate within t 2.5 ppb.' 3) ' ' - On September 20, we collected 50 mosquitofish (Gambusia affinis) from Choccolocco Creek (4- miles east of Boiling Spring) and subjected them to bioassay. These screening" casts indicate 36-hr TL^ values of'about 80 ppb for parathion and' about 60 ppb for'methyl parathion. The . accuracy of these estimates will improve when additional specimens are.tested. 4) The following is a summary of water, mud, and,fish ssnples analyzed to dace: DATE COLLECTION SITE SAMPLE PESTICIDES (ppb) S/13/66 Bridge - 4 miles E.

Z. C. Fuimeisoer Technical Services Superintendent Monsanto Chenlcal Company * Anniston., Alabama 3^202 Dear Mr. Fuhrmeister: z' ^ ^tV r*. H^r QS to>' VTe have been, bavins problems 1 High vater in Choccolocco Creek hindered attempts to replace fish in our cages until last veekand (jan. 15). Also, vater samples collected during high vater failed to provide useful information concerning microflora. These analyses Here done by our Microbiology Department and will be repeated when the stream flov returns to normal. . The sost vexing problem has been the appearance of a large peak on Gas chromatograms that coincides with parathion--this peak vas found in samples from all of oar stations. Initially, ve thought it to be parathion. However, when ve found it upstream from Anniston and because of its peculiar behavior on thin-layer places, ve decided that It vas not parathion. let, the .peak masked the actual parathion peak (if any) end prevented quantitation of parathion in samples. After rechecking vt equipment, reagents, and other materials used to process samples, ve finally discovered the source of the mysterious peak. It seems that hexane stored In polyethylene squeeze bottles picks up at least three contaminants, one of vblch has the exact same retention time as parathion. This has been a most exasperating experience. The following samples vere analysed vith the problem peak present, and ve quantitated the peak as thcogh it vere parathion.

C. Tukrseister Page 4 Although the scans suggest a 10-2!$ inhibition in the caged fish, t_h_i_sdifference is not significant at the % level when tested with a z-zest. However, the t-value (2.501) barely missed being significant (t 2-571 with 5 d.f.), in spite of the inadequate sample size. A preliminary literature search has revealed several reports of enzyme inhibition by mercury, especially seme of the enzymes involved in degradation of phosphate insecticides (See R. D- O'brien. i960. Tonic phosphorous esters. Academic Press, E. T. p. 119). Ve have sons studies underway regarding possible synergistic or additive effects of mercury and paraehion. We are not yet ready to report our findings. In conclusion, it is obvious that all our data are incomplete. A number of materials originating at the Monsanto Plant (via Snow Creak) are shoving up in fish and mud samples taken downstream few Anniston. We hope to mate a trip to Anniston soon and bring chrcnatogrsms to illustrate this phenomenon. We have not been bl ^ to detect parathlon in Cnoccolocco Creak. Studies of passible cholinesterase inhibition, in caged fish bold promise but are still incomplete. .* Preliminary flow-through, studies and an investigation of tha .

Both, of our gas chromatographs are down nd it will be a while before we are able to have them, repaired. We have a large number cf samples being processed. . On March 5, we collected a water sample from Dry Creek (at the Hiway 202 bridge). Ihe attendant at the service station said that fish had been killed in the creek. Elis man claims that several cattle died as a result of drinking from Dry Creek. He said that on Friday afternoons the creek ns a real mess. However, when we collected the water samples, I observed live scscuitofish in the creek, thus, I am not convinced that the stream ` is as bad as he thinks. Seme samples should be taken"on Fridays used for bioassay tests, of bluegilis. I gave the Mississippi State Chemical Lab 2 bluegilis and a carp for mercury analyses. They seemed to doubt that they could do a quantitative analysis, but premised to do their best. If you people have competent, chemists who could do mercury analyses on some of the dead fish from down scream, I suggest that you get them busy, especially in view of the cholinesterase data below. We caught a number of fish of several species at Jackson Shoals, including seme minnows and .small bass for residue analysis on GLC. On March 5> we obtained 23 small bluegilis from Choccolocco Creek at Jackson Shoals (ca. 150 yards below the confluence of Eastaboga Creek). . Cholinesterase levels were determined for 20 of these fish using the brains of 2 fish as a single sample. On March 7, cholinesterase levels were run on 10 bluegilis from our control population at the Country Club. Procedure, chemicals, and other variables were identical in tests of these, two groups Cf fish. : DSW 162383 HARTOLDMONO014980 March 10, 15c7 Page 2 In Table 1, A-l through.

Ivcte the clean sample from the fish taken upstream. Many of the peaks in the downstream fish are those we have found in Snow Creek. Could rhis be the reason that the SE Lab did not do GLC analyses of fish tissues as a pant of their report? Note that we indicate retention .times for several pesticides on one tracing. The peaks do not match these times perfectly, indicating that they are not pesticides.
