Confidential information

In last week's edition of Mixed Greens we talked about a recent study of the effects of PFOA, a persistent perfluorochemical with toxic effects on the liver, thyroid and immune system. That study, funded by part of DuPont's multi-million dollar settlement over poisoned river water in the mid-Ohio valley, is the largest of its kind ever performed.

Researchers on the study have only just begun to crunch the mountains of data that have been collected. But those mountains may pose a problem, according to an area judge who has sealed the data from the public. The records contain details about blood-PFOA levels as well as health and demographic information about 70 thousand mid-Ohio valley residents. Citing confidentiality concerns, the judge sealed the data – including the version which omits identifying data.

Qualified researchers will be able to petition for access to the data, and results from the WVU study will be released over as they become available.

So, what do you guys think? Does sealing the data put up unnecessary road blocks for those looking to study the health effects of PFOA? Or is the judge doing right by the study participants?
