Child cancer victims in Clyde say report shows reasons for cancer cluster

Some families whose children are part of a northern Ohio cancer cluster say they're troubled after soil samples from a former park showed high levels of a chemical believed to increase the risk of certain cancers in humans. Attorneys for the family members cite a recent report prepared for the federal Environmental Protection Agency about park grounds in the Clyde area, where at least 35 children have been diagnosed with cancer since the mid-1990's.  The report says soil samples taken near a basketball court showed metals and PCBs, or polychlorinated biphenyls, in amounts exceeding EPA levels.  The report says a tip left on a hotline indicated a company used a black sludge-like material to fill in the area near the court.  The family members plan a news conference later today.
