But Dr. Irving Sellkoff of the ML Sinri Medical Center, who fa now studying workers at the two plantr on the Hudson, warns that to assume the problems are limited to ekin rashes "would be in error." Meanwhile, as Monsanto, ola U.8. producer of PCB's, supplied an ever-growing de mand for the product all through the 1900's, mink ranchers in the Great Lakes region were having mysterious problems getting their fomele minks to reproduce. "These ranchers were getting wiped out," says Robert Ringer, a physiologist at Michigan State University, "and (hoy didn't know why." Dr. Ringer sus pected the trouble was the DDT In the Greet Lakes fish that tha mink ate. But even when he fed them fish con taining unusually high levels of DDT, hfs laboratory mink want right on reproducing, in 1008. Dr. Ringer finally de termined that the problem was not DDT tat PCB's. A liny amount--fust 0.104 parts par million (p.p.m.) -- slopped mink reproduction. A larger amount--8.87 p.p.m.--killed all the adult minks. Even this laal figure is well tinder tha maximum of S p.p.m. that tha VS. Food and Drug Adminis tration currently allow* in food for human consumption. Other experimental evi dence was piling up. One American rteearclter fed PCB's to rata and produced tumors. Another, James Allen, a pathologist at the University of Wisconsin, fed PCB's to monkeys and produced the symptoms of the Yusho syn drome, Including reproductive problem*. In female monkeys that ware fed PCB's at the P.DA.'s pomissilde level for humans, 8 p.p.m,, only one In right gave birth to normal offspring. And once the Infant monkeys began anirting, they were subject to further hissrds. Since PCB's moves rap idly into fatty parts of the body, the aubstape* became concentrated In the mother's milk. Hence, the level of PCU's present in the infant* at birth subsequently Increased 100 times. As the danger flag* went *p, Monsanto Legsn limiting sales In 1971 to manufactur ers who used PCB a ta "closed systems"--that Is, in Inina formers and capacitors, where the ralptsmc is sealed In and Ml exposed.

But even "closed systems" don't stay closed forever: Old capacitors and transformer* continue to be discarded la dumps where they eventually break open and Irak PCB's into the soil. Though Monsanto acted vol untarily, it surely would have been forced kilo such a tan by a Federal task force ihen studying PCB's. In Jspan. that same year, all PCB production was ordered stoppled. But G.E. continued to be Monsanto's blggeit PCB cus tomer; in 1970, It tad pur chased a record 4.M0 tons, and the bulk of It went to the two capacitor pignts on the Hudson River.

Wise! (he slate would not do for itself was finally done, in August 1974, by Royal Na deau and Robcri Davis of llte local office of the E.P.A. Disturbed, along with a few others in tlte agency, by report* of high PCB levels showing up around the country, they decided to check out the Hudson River, wUh special atlentioa to the aeclkm below Foil I'dward and Hudson Falla. Ihla was hardly s brilliant idea, of course, since O.E. had been announc ing Ha PCB discharges in permit applications for years. Nadeau and Davis found cMiaordlnarlly high levels of PCB's in the water, river mud and living creatures In the vicinity ol the O.E. plants. Just below Fort Edward, (hey found what was, until then, a 'Sverkt's rec ord" for PCB-mfested fish--a rock bass meas uring In at SS5 p.p.m. They could hardly believe K was alii) alive. For a full year, the report of tlte two acientiila floated around. It finally reached Oilman Veilh, a chemist at the E.PA.'a National Water Quality Laboratory In Duluth, Minn. Dr. Veilh had first come up against PCB's as s graduate student working on the mink problem in the 1090's. Npv ha was watchdogging PCB's nationwide. 'T was con vinced after reading this report," he says, "that the Hudson River situation was the worst I'd seen In the country by at least a factor of ten." Veilh wrote a review of that report emphasising It* seriousness, and sent It off to the director of the E.P.A. regional office In New York. It was forwarded. In July of last year, to Ogden R. Reid, who had been CommIntoner of the D.E.C. for Just six month*. At Iasi, thinga began to happen. Startled by this alert all the way from Duluth, Riid poked around hit own department to sea If anyone knew about the PCB problem. He was flabbergasted to discover that plenty was hnown, but nothing had been done. Nobody had even bothered to tell him apout PCB's. Raid found that he had to develop new com munication lines to Insure he would get PCB memos--Including those of Ward Stone. That August, ReM warned tho citizenry not to eat striped bass from the Hudson or salmon from Lake Ontario, a warning he wefilrt convert Into a ban in the Hudson by February. He Iso ordered an administrative hearing, chaired by a Columbia University law profes sor, Abraham Softer, lo determine If Q.B. had violated Mate water-quality standards and, If so, what sort of restitution the com pany should reasonably make. At those hearing*, held Iasi November, a parade of atatr'a witnesses testified that PCB's are toxic to a wide range of living creatures. Including man. II was site made strikingly clear not only how high PCS counts were downstream from tlte G.E plants (79,000 p.p.m. at the Hudson Falls outflow), but how tow they were just a few hundred yards upstream (practically negligible). Aa a result of new aurveya, the record established by Nadeau and Davis with their rock bass was easily broken by many fish. The new record holder was an American eel contain Ing 97S p.p.m, of PCB's. It would have supplied a consumer with more than half his lifetime PCB limit aa set by tlie PBA And in Canada, where the maximum PCB eonlcnl of edihte fish is 2.S p.p.m rather than ft, -that tingle meal would have easily exceeded the lifetime safe limit. _ Given such testimony, H came as qulle a - 7" HONS 0 4 6 8 9 3 I surprise when O.E. Intro duced lit own experl wIlMtes, Oerald Leucr of Ecological Analysts, inc.. who presented his finding that fish taken from below the two plants did not contain KB level* in extent of the torrent standard of I p.p.m. Upon crow-examination, Latter had trouble deciphering hi* own note* and table*. II turned out, furthermore, that the laboratory In Tennessee that had mult the analysis had botched the Job. O.E. with* drew Leurr's testimony. O.E. did better with its basic ``affirmative defense," which held that it had applied for and been granted both elate and Federal permit* to dis charge PCB's. How could it bo penalised for scrupulously following the lew? Softer greed that this argument had "more than superficial ap peal" But It waa not enough to excuse O.E. from the gen* era! requirements of It* per mit, which forbade the rtomirany to violate stale water-quality standards even If the precise prohibitions were not spelled out. Accord ingly, Bofacr ruled thet "O.B, has discharged PCB's In quan tities thet have breeched applicable standards of water quality . .. injured flab, and . . . destroyed the viability of recreational fishing In various parts of the Hudson River by rendering its fish dangerous to consume." - It came out during the HearInge, most interestingly, that even before the KB problem became public. O.E. already had determined that further significant discharges could be eliminated without much dllflcully. KB's entered the river primarily via watte water* used to wash off the casings of capacitors that had been submerged In PCB bath. This water could easily be contained and the PCB't destroyed by ultra-hightemperature Indnerattoo. O.E. was not the only party to leas out. Just four months after Bofaer** decision was announced, Ogden Reid found Me position untenable and resigned after a year end a half as Commissioner of the D.E.C. Several things had gone wrong, but the main one was that he had picked an Inoppor tune time to go after O.E.--the middle of Oovernor Carey's desperate campaign last win ter to keep the elate from being pulled down by New York City's financial collapse. Looking forward to the erltleel "spring borrowings." Carey was busy telling the financial community what a wonderful and hospitable place New York was to do business, while Reid played the heavy to one of the Male's . . -I- top corporal* elttxeni. At one tense meeting with Carey end Reid, the O.B. board chairmen, j Reginald Jones, is reported to have angrily warned that he would pull all company facili ties out of New York If ReM forced the two Hudson River plants to go to sero-KB dis charge before O.E. timughl it feeelble. Publicly, Carey never backed off from defending . Reid on the O.E. issue. But neither did he Mop a vigor ous frontal attack by Reid's fellow commissioner, John Dyson of the State Depart ment of Commerce. "If xrro discharge means aero Jobs end three ounces means MOO Jobs, I say we go for three ounces," said Dyson, in one of his many utterances. Reid's downfall was has tened, no doubt, by a manner thet struck many upper-level departmental bureaucrat* as being peremptory and Insensi tive to the pecking order. As the end approached last win ce, three of those bureaucrat* resigned together in protest of Reid's leadership, Reid even bad the Albany press sniping at him over departmental "morale" right up to the day of bl* resignation. At preas conferences, certainty, Reid did not have Cerey'e light touch and fancy footwork in fending off sticky questions. At sensitive time for the state in Its relationt with In dustry, Reid carried a Mg stick but walked loudly. Though Reid is gone, re placed by Paler A. A. Berk, and O.E.'s PCB discharges are oil but ended, x momentous problem remains: the estimated 500,000 pounds of KB's on the river bottom downstream from the plants. The slate has roughly gC.4 million with which to attack the problem-- bout $3.4 million of it from the settlement with O.E. (The rest of the O.E. money will be spent on studies of other chemicals In the Hudson, toeluding the one O.E. plans to use In place of PCB'*.) The (tret step, which will cost bout g! million and take six months, le to find out what can be done. This will consist mainly of mapping the precise tocattons and depths of the KB's, which now ap , peer to be concentrated be.hind the eight dams on the river between Hudson Fells . and Troy.

In the IS days of heaviest river flow each year, according to D.E.C. tests, as many as 10,000 pounds of KB's may pass over the Troy dam.

Then will come the swift striped bass and the ancient, lumbering sturgeon. As all these fish move upstream, they wifi unavoidably eecumu. late pcr. Aod, despite the landmark agreement betwen the company and the stale, "body knows when those fish will be free of KB's, or rree enough, si least, to allow the river to be reopened to j commercial fishing.
