THE CLAMS WERE ACCLIMATED FOR 1 TO 2 WEEKS IN HOLDING TANKS AT 25C, 8.2 PH, AND 15.6 PERCENT SALINITY. THEY WERE THEN TRANSFERRED TO EXPERIMENT TANKS WITH WATER HAVING LIKE PROPERTIES AND A DIELDRIN CONCENTRATION MAINTAINED AT SAMPLES OF CLAMS AND WATER WERE REMOVED AFTER 12, 24, 36, 48, 60, AND 72 HOURS AND AFTER FREEZING AND CLEANUP OF THE MEAT SAMPLES WERE ANALYZED FOR PESTICIDE RESIDUE BY GAS-LIQUID CHROMATOGRAPHY. THE RESULTS INDICATED THAT RANGIA IS CAP CONCENTRATING DIELDRIN IN ITS TISSUE TO LEVELS FAR THE SMALLEST DIELDRIN RESIDUE IN EXPERIMENTAL CLAMS WAS 38.2 MICROGRAMS/LITER AFTER 12 HOURS EXPOSURE AND THE LARGEST 1226 MICROGRAMS/LITER AFTER 60 HOURS. APPARENTLY THE DIELDRIN IS NOT NOXIOUS ENOUGH IN THE CONCENTRATION USED TO AFFECT SIPHONING AND THUS IT IS ACCUMULATED IN QUANTITIES THAT MAY BECOME A THREAT TO THE ESTUARINE FOOD WEB.
