1 -- Computer charts alcohol level Two new computer programs developed at the University of Toronto can predict a person's seam blood alcohol concentration and the relative risk of a traffic acci- dent after alcohol consumption. The Blood and Breath Alcohol Concentration (BBAC) program combines personal data (gender, age, height, weight, metabolic rate) with details of the timing, amount and type of beverage consumed -- and whether food was eaten as well - to chart a per- son's blood alcohol concentration. "This program can be used by lawyers and police officers to estimate whether an accused per- son was over the legal limit at the time of the 'occurrence:" said Dr. of Pharmacology. For instance, Dr. Giles said a 25-year old man, 180 cm tall and weighing 70 kg., with an average metabolic rate, would have a maximum alcohol level of fo milligrams of alcohol per 100 millilitres of blood if he consum- ed eight whiskies on an empty stomach over three and one-half hours. The legal driving limit is 80 milligrams of alcohol per 100 millilitres of blood, but a person can be impaired at a lower level. The second program called RISK combines the same data as Gwynne Giles of the Department BBAC and also considers marital IT PAYS TO ADVERTISE ADVERTISE WHERE IT PAYS LANDSCAPING SERVICES LEAKY LAWN ALEX'S LANDSCAPING & DESIGN Tree Planting - Inter-lock Stone Fencing - Decks - Maintenance Masonry Repairs - Painting 985-3873 985-3197 CLARK PROPERTY MAINTENANCE LANDSCAPING BACKHOE & BOBCAT SERVICE RETAINING WALLS LAWN MAINTENANCE INTERLOCKING BRICK Year Round or Seasonal Contracts 985-9312 649-2515 852-9585 i: \; LANDSCAPE DESIGN and CONSTRUCTION * Interlocking Stone * Flagstone (Dry, or in concrete) * Retaining Walls -& Steps - Timber - Stone * Rockeries * Foundation & Large Tree Plantings * Sod and Seed * Fencing & Decks Undergroupd Sprinklers Service & Installation Customized Dgfit-yourself Kits 1-800-387-4283 LANDSCAPING University Werks Interlocking Brick -- Wood Decks Wood Fencing -- Retaining Walls PROFESSIONAL DESIGN & QUALITY PRODUCTS ALL WORK GUARANTEED FREE ESHMATES CALL: 985-2289 666-9690 REESOR WEED CONTROL Specializing in: Government Licenced * LAWN CARE - Port Perry - * FERTILIZING 985-3383 * WEED CONTROL * CHINZ BUG ANALDA LANDSCAPING & NURSERIES (5 miles east of Port Perry) HWY. 7A and West 1/4 Line 2868-4771 TREE SERVICE UXBRIDGE FOREST GARDENS LTD. * Tree Pruning or Removal " * Bucket Truck & Brush Chipper * Stump Removal * Fully Insured 852-7087 For-us-tree Service P.O.

Results from the Grand Rapids traffic study .-- a major traffic ac- cident study done in Michigan in the 1960's -- were incorporated in- to the data base to help calculate the risk. ~ 3 Using RISK, Dr. .Giles com pared two 180 cm, 70 kg men who consumed five drinks over three hours, one aged 16 and the other aged 40. The 16-year old, who was single, had partially completed high school and drove 100 km/month, had a traffic accident risk six times that of the 40-year old, who was married, had an undergraduate university degree and drove 10,000 km/month. "Teenagers and alcohol are a disastrous combination," said Dr. Giles. "They continue learning to drive even after passing the driv- ing test. Any disturbance during this continuing learning process can have significant conse- quences. If they drive after drink- ing, errors are inevitable and an accident is far more likely." "Both programs can be used to help educate people on some of the dangers of alcohol abuse, as well as illustrating the increased flanges of drinking and driving," 4 e said.
