Any time there's an article in the paper, in a magazine or a story on the news about some newly discovered "health risk", everyone freaks out about it.
I work for a chemical manufacturer that provides raw materials (urethanes, polyurethanes, plastisols, foams, elastomers, etc) for OEMs that make everything from kitchen utensils to ... uh... hmmm... "adult toys".
The level of BPEs or other phthalates that you would expose yourself to in using a basic paint bucket are inconsequential and would pose a statistically insignificant risk to your health. Chances are greater that you'll get hit by a bus or win the lottery before you'll suffer any negative effects from the levels of harmful chemicals in those buckets.
However, if it makes you feel better and you absolutely have nothing else to worry about in your or anyone close to you's life, then by all means, make sure you get the exactly "right" bucket.
