If life were fair art would be a naturally green endeavor. You could paint a mural, mosaic a table, or glaze your ceramics without a care. But this is the real world, and paints, glues, and glazes can pose hidden health hazards that we should be aware of.
Labels to Look For (and to Look Out For)
All art supplies sold in the US must bear the phrase, "conforms to ASTMD 4236," confirming that they have been properly labeled for chronic health hazards, in accordance with the federal Labeling Hazardous Art Materials Act (LHAMA).
To go even further when it comes to art materials and safety, also look for labels from the Art and Creative Materials Institute (ACMI). ACMI is a nonprofit membership organization made up of art supply manufacturers, who voluntarily agree to have their materials evaluated by independent toxicologists and tested by accredited, independent labs for safety every five years, as well as randomly and whenever product formulas change.
Here are a few places where you can find eco-friendly art supplies:

Studio Safety - What you need to do to stay safe
Substitution or elimination of the hazardous agents
Exhaust ventilation, process enclosure, dilution ventilation
Store chemical products properly. Containers should have screw-top lids
Store acids in separate cabinet and in glass or plastic containers with a plastic lid
Flammable liquid storage - lids tightly closed when not in use to prevent vapors from igniting
Personal protective equipment (e.g., respiratory protection, gloves, eye protection)
Wet-wipe surfaces rather than sweeping or vacuuming (and if you must use a vacuum, make sure it has a HEPA filter). Avoid carpet use.
CERF has created a Studio Safety Guide that helps protect you and your art. Take advantage of this helpful tool.
