In 1990, Congress created a new regulatory commission called The Ozone Transport Commission (OTC). OTC was developed to alleviate ground-level ozone problems in the Northeast United States. Effective July 1st 2009 Rhode Island and Massachusetts will now follow new Volatile Organic Compounds (VOC) regulations under OTC guidelines. The total number of VOC allowed must be below 350 g/l.
What does this mean? Good bye to dangerous finishes such as moisture cure.
The solvents and reactive chemicals found in moisture cure polyurethanes begin to evaporate into the air soon after application. Immediate exposure to their fumes can lead to temporary irritation of the eyes, nose, and throat and cause annoyances such as headaches, nausea, and dizziness. Very high and/or long-term exposures can lead to more serious health issues such as organ damage, birth defects or pregnancy complications, chemical allergies, and, possibly, cancer.
Whats a better way to finish my wood floors? Oil or water based polyurethanes.
thats only untill it dries long term expoisure means like someone who is applying the mcu like working for a floor company now read it again btw its exectly the same words found on the health dept web site

David Smith at Keele University, UK, and his team have found that volatile organic compounds (VOCs) are generated by cell cultures in proportion to the number of cancer cells and could be used as biomarkers for tumors. Following some conflicting results, Smith's team optimised their selected ion flow mass spectrometry (SIFT-MS) method to measure the acetaldehyde emitted by both malignant and non-malignant cells cultured in vitro. Smith was able to exploit a recent advance in SIFT-MS which allowed the production of carbon dioxide to be measured as well.
The study confirmed that the different lung cell lines had different VOC signatures, says Smith. 'This extremely interesting finding paves the way for detecting particular cells (including tumour cells) on the basis of their VOC signature' says Claire Turner, an expert in VOC analysis at the Open University, Milton Keynes, UK. 'The long term significance is that it may be possible to not only detect cancer through VOC analysis but also to non-invasively identify the tumour type'.
'This work will be continued with the investigation of other cell types, malignant and non-malignant, in the search for volatile biomarkers of other cancers' adds Smith. He hopes that in future the technique could be introduced into the GP's surgery to allow routine and opportunistic screening for cancer and also for other diseases, such as diabetes and kidney disease.
George Hanna, a consultant surgeon at St Mary's Hospital, London, UK, agrees that this could be possible, saying '[this technique] has the potential to change clinical practice being a simple non-invasive test. It is ideally placed to be a practical screening test that changes clinical practice
