PITTSBURGH, PA, United States (UPI) — Pittsburgh Mayor Bob O`Connor died of brain cancer Friday night at 61, less than a year after his election to a post he had sought for years.

A spokesman told the Pittsburgh Post-Gazette O`Connor`s family was with him when he died at the University of Pittsburgh Medical Center Shadyside Hospital.

City Council President Luke Ravenstahl was sworn in as mayor at 10:30 p.m., less than two hours after O`Connor`s death.

O`Connor won the mayor`s race last November in his third try for the office. The newspaper characterized him as an energetic executive, leading a campaign to clean up the city in time for the Major League All-Star Game in July.

Shortly before the All-Star break, he was diagnosed with cancer. He spent the day of the game getting his first chemotherapy treatment.

O`Connor got into politics by running for the city council at age 45, after five years as a steel worker at Jones & Laughlin and a career as an executive with a restaurant company.

Washington, Sept 2: Scientists studying the harmful effects of exposure to lead have found that people who are routinely exposed to it are 50 percent more likely to die of brain cancer.

The study, based on information from the U.S. Census Bureau and the National Death Index, was conducted by researchers at the University of Rochester Medical Center, and provides further evidence that widespread environmental risk factors such as lead must be explored.

The study computed the risk estimates for lead exposure and brain cancer from a census sample of 317,968 people who reported their occupations between 1979 and 1981.

Edwin van Wijngaarden, Ph.D, the study’s author said followed the cancer rates of 318,000 people for nine years. He found 119 brain cancer deaths.

He found that the death rate among people with jobs that potentially exposed them to lead was 50 percent higher than unexposed people, and the number of deaths was larger than in many previous studies.

The study is published in the Sept. 1 issue of the International Journal of Cancer. (ANI)
