Are Paint Fumes a Health Concern? Here ’s What the Latest Science Says

If you’re one of the many homeowners considering using this summer to repaint your house or apartment, you might have been concerned to hear that, according to a just-published study in the journal Occupational &Environmental Medicine, women exposed to common paint chemicals at work are more likely to have a child with autism spectrum disorder. Further, the greater the exposure, the greater the autism risk, the study found. These risks remained even after the researchers adjusted their data to account for other potential autism factors, such as a woman’s smoking history, alcohol habits, and age at the time her child was born. The new study isn’t proof that paint and related chemical exposures cause autism, and should be “interpreted with caution,” the authors write. But the findings are in line with previous studies that found an association between paint chemicals and autism. And there’s a growing body of evidence linking the many chemicals found in paint and its fumes to a number of health issues. Benzene, for example, is an established carcinogen that turns up in some paints, particularly oil-based paints, as well as in art and crafts supplies like glue and dry-erase markers, vehicle exhaust, and pesticides. As with other carcinogens, it’s likely people mostly have to worry about long-term or very high amounts of benzene exposure. But spending time in a poorly ventilated and newly painted room could expose people to elevated b...

We report a molecular dynamics investigation on dilute and concentrated solutions of four acidic organophosphoric extractants (P507, P204, P227 and Cyanex272) in pure oil phase and oil-water biphasic systems for purpose of depicting solution and interface behaviors, which has been a cornerstone of chemistry in solvent extraction and separation. We can intuitively find that the single extractant promotes the interface movement. When the extractants get concentrated in organic phase, they diffuse and aggregate to dimers and trimers. In oil-water biphasic system, most of the extractants tend to migrate to the interface and re...

The presence of OMP changed the film-forming solution from Newtonian to non-Newtonian fluid. The addition of OMP and RAs decreased the crystalline of PVA due to the hydrogen bonds among RAs, OMP and PVA. An appropriate content of RAs ...

In this study, a fast method for evaluating the total oil yield using a single routine Rock-Eval experiment on as-received shales is proposed. First, the temperature threshold (TOK) of the S2oil and cracking hydrocarbons were determined by combining the pyrograms of the as-received shale with a solvent-extracted replicate. Then, the total oil yield was directly derived from the hydrocarbons evaporate at a temperature below than TOK in a routine Rock-Eval experiment. The results show that the TOK value is controlled by the sample’s maturity and pore structure. The higher the maturity, the larger the specific surface a...
