When we arrived in Switzerland a few days ago, I posted about my family’s Swiss origins. My father was born near Zurich 120 years ago. I gave a brief bio on dad and mentioned that he spent most of his work life at the Morse Chain Company which had a factory at the top of South Hill in Ithaca, NY. We rented half of a house further down South Hill.
Dr Samuel Goldman of The Parkinson's Institute in Sunnyvale, California, who co-led the study published in the journal Annals of Neurology, commented:
Our findings, as well as prior case reports, suggest a lag time of up to 40 years between TCE exposure and onset of Parkinson's, providing a critical window of opportunity to potentially slow the disease before clinical symptoms appear.Unfortunately my 40 years are up. Perhaps others can be spared.
Recent environmental studies continue to find TCE contamination on South Hill, even though the company stopped using the chemical almost 40 years ago. I can only imagine how high the contamination levels in our old neighborhood might have been 70 years ago.
Groundwater contamination by TCE is widespread. Studies estimate up to 30% of U.S. drinking water supplies are contaminated with TCE. In Europe, the chemical was reclassified in 2001 as a "category 2" carcinogen, although it is still used in industrial applications.
