(AP) - , Recent test* by a private ; agency show PCB levels well , within federafUmlta In fish | takes from UJm Pepin, but authorities say further testing i mnat be done before conclu- , done oaa be drawn. 1 The trade PCBa -- poly chlorinated biphenyl* -- were found last month In fish taken I from Lake Pepin. The flab ' contained quantities of the la* duatrial chemical exceeding the federal standard, five parti par million, resulting in a federal ban on the Interstate sale of Lake Pepin fiah. The chemicals are believe . to cauaa birth defects and re* Sreductive failure in fish, Irdt and mammals. They al so are suspected of causing cancer among human beings. I Lake Pepin fishermen say , they had a teat made recently , by the Wisconsin ALumni Re- serch Foundation (WART), Madison. The teats reportedly : showed PCB levels In nine ' fish taken from a typical aein- lng area In the late to be be low one part per million. Darryl Brown, chief of the U. S. Food end Drug Admints^ (ration laboratory in Mlnneap- olU, says the data la not con clusive. He suggested the fiah taken (or the WARP (anting were different In else from those tested previously. Brown said be has "full confidence'' in the WARP lab oratory and the procedure* it used in tatting the latest sam ple. But he noted that differ ences In sisscould account for a difference is PCB readings. Scientists have theorised that PCB has more chance to accumulate in an older, larger fish which has more fatty tis ane In which the chemical can I lodge. ( HONS 031U3
