Risks associated with exposure to chromium, and non cancer risks from arsenic are incorporated in the study.
EPA noted that uncertainties exist in the risk assessment, including uncertainty in the toxicity of arsenic, the level of arsenic residue on the surface of the wood, the amount of arsenic absorbed, etc.
You can usually recognize pressure treated wood by its greenish tint, especially on the cut end, and staple-sized slits that line the wood.
However, the greenish tint fades with time, and not all pressure treated wood has the slits.
Arsenic has been associated with lung and skin cancer and is acutely toxic.
The draft preliminary risk assessment demonstrated an increased risk of cancer for children who regularly played on pressure treated play sets, and a greater increased risk for children who also were exposed to pressure treated decks in the home.
Should I take any other precautions when I work with pressure treated wood?
Arsenic that leached from the play sets to the soils underneath was included in the assessment of exposure.
EPA's draft preliminary childhood risk assessment takes into consideration variations in exposure due, for example, to climate, weathering of the wood play structures, whether the child also spends time on a pressure treated wood deck, and months of the year that outdoor play occurs.
How are children exposed to arsenic from pressure treated wood?
When was pressure treated wood found to present health risks?
