The Michigan Daily-Tuesday, May 22, 1979-Page5 PBB found in 70% of Michigan residents LANSING (UPI)-About 70 per cent of Michigan residents have detectable amounts of PBB in their blood, state health officials said yesterday. According to the most recent progress report of a statewide PBB study, about half the state's residents have .5 parts per billion (pbb) or less of PBB in their blood and about 5 per cent have 5 ppb or more. Cows may be sold for food with as much as 20 ppb in their fat. THE PROGRESS report noted that fat concentrations of PBB generally are higher than PBB blood levels. "Although the blood specimens show only 70 per cent with PBB detectable levels, results from the fat anaylses will undoubtedly increase the percentage showing some exposure," the report said. "The results of these tests should be done by the time of the final report, to be issued September, 1979." EARLIER STUDIES estimated PBB could be detected in fat samples of 90 per cent of the state's population. Another survey showed 96 per cent of nursing mothers had detectable levels of PBB in their breast milk, which has a high fat content. In general, the most recent report said, PBB levels were higher in children than adults and in males than in females, as had been found before. But for the first time, data showed white people had higher levels than black people. 'The public was primarily exposed to PBB through use of food products distributed locally ...' -from a state Dept. of Public Health report The study, funded by a $2.2 million state appropriation, is being coor- dinated by the state Department of Public Health and conducted by the University's School of Public Health, Wayne State University and the Mount Siani Environmental Sciences Laboratory in New York. IT HAS NOTED differences in PBB levels by geographic region. "The general public was primarily exposed to PBB through the use of food products that were distributed locally," the progress report said. "Since the majority of the affected animals were from the western part of the state, the levels of PBB in the general population tend to be higher in that area," the report said. "THE DATA do not substantiate an earlier conjecture by some that the PBB was primarily distributed in lower quality meats that found their way to the poorer households of the state." Efforts to develop methods of flushing PBB from the body have tur- ned up "interestjng preliminary results," the report said. "The .tests so far indicate that rats fed PBB and then given diets with high fiber content or certain absorbant materials have lowered their PBB levels faster than those on regular diets," it said. "IT IS MUCH too early to tell whether or not this will result in the development of means for people to rid their bodies of PBB and possibly other chemicals." PBB entered Michigan's food chain when it was accidentally added to livestock feed in 1973. Nuke plant on line, high costs follow SOUTH HAVEN (UPI)-Consumers Power Co. brought one of its two ailing nuclear power plants back on line yesterday, ending three weeks of down- time that forced the utility to buy power from other utilities at a cost of $330,000 per day. The $1115 million Palisades nuclear power plant was back in operation at 12:35 a.m., utility spokesman Mike Koschik said. THE PLANT shut down April 30 when a faulty voltage regulator caused its main turbine to trip and shut down the reactor. Before the facility was brought back on line, the utility revealed a computer analysis, performed because of the utility's plans to replace two defective steam generators, showed two emergency reactor cooling systems were not as earthquake resistant as originally believed. Since May 2, plant engineers have been shoring up the two systems which involve braces holding about 100 feet of 12-inch diameter piping running from two 7,500 gallon water reservoirs to the plant's nuclear vessel. ADDITIONAL BRACES were in- stalled at a cost of $25,000 to make the plant resistant to an earthquake four times more powerful than any that hit the area in the last century, Koschik said. The plant shutdown caused Con- sumes to buy electricity from other utilities at an estimated cost of $6.3 million. Koschik said, however, engineers had not yet determined how to repair Con- See PALISADES, Page8 Inmates suspected in prison poisoning JACKSON (UPI) - Officials at Southern Michigan Prison locked three suspects in detention cells yesterday in the poisoning of at least 27 inmates who spiked their fruit juice with a wood alcohol-based fluid used in duplicating machines. Nineteen inmates were hospitalized in outside facilities as a result of the weekend outbreak at the nation's largest walled prison and two remained in critical condition, officials said. Another eight inmates were treated at the prison infirmary. SEVERAL OF the victims suffered temporary blindness, prison officials said. The first noticeable symptom in most cases was severe stomach cram- ps. Three inmates suspected of stealing the fluid and selling it to inmates as pure alcohol were locked up in deten- tion cells pending further investigation, said a spokeswoman for the state Department of Corrections. They were not immediately iden- tified. THE STATE spokeswoman said blood tests were administered to 94 in- mates who reported poisoning sym- ptoms or other ailments or believed they may have ingested the poisonous fluid. "The people at the prison infirmary say they're still coming in, even now," she said. The most seriously poisoned inmates were taken to hospitals in Jackson, Lansing, Ann Arbor, Flint, Grand Rapids and Detroit for blood dialysis treatment to cleanse their blood of the wood alcohol. ONE OF TIRE critically ill inmates was identified as Paul Hinds, 35, Detroit, serving up to 15 years for burglary and prison escape. He was being treated at University Hospital. Prison officials said six packages of the fluid, used in mimeograph machines and other equipment, ap- parently were stolen from an office supply center within the main prison complex. The poisoning outbreak started in Cellblcok-11, a close-custody unit which lodges inmates incarcerated for a variety of offenses, and spread to other cellblocks. JAMES POGATS, administrative assistant to the warden, said that while inmates sometimes try to produce their See JACKSON, Page8 Edison expects rate hike of $69 LANSING (UPI) - The state Public Service Commission (PSC) is to decide today whether Detroit Edison Co. should receive a multi-million dollar rate hike to cover the costs of a new power plant critics say should not have been built. An Edison spokeswoman yesterday inadvertently read a statement praising the PSC for approving the in- crease, but later denied the company had early inside information about the decision. SHE SAID Edison prepared the statement for possible use in case the recommendation of the PSC staff is ac- cepted by the full commission. Edison asked the PSC for an-interim rate increase of $69 million to tide it over until a final decision is reached on its request for a permanent increase of $166 million. million The interim increase would cost the average Edison customer about 80 cen- ts per month. EDISON, THE state's largest electric utility with 1.6 million customers, last received a regular rate increase in Sep- tember, 1978, when it was granted $83.7 million. However, the firm received about $19 million earlier this year through a new PSC program of annual rate adjust- ments to compensate for the effects of inflation on operating and maintenance costs. The PSC staff recommended a $56.9 million interim rate increase to cover costs Edison faces when its new 800 megawatt Greenwood No. 1 oil-fired power plant begins operation later this year. Those costs include depreciation and the expenses of operating the $370 See EDISON, Page 9 earn $1OO a month for 2 or 3 hours a week of your spare time. donate plasma You may save a life!
