KELSO, Wash. – Columbia Analytical Services, Inc. announces a new website service that allows users to search the California Proposition 65 (Prop 65) chemical list online. The database of 775 chemicals is searchable by a CAS registry number or by the chemical name and when clicked, shows the risk level, maximum allowable dose level, type of toxicity, date listed, and listing mechanism.

“This appears be the only searchable Prop 65 chemical list on the internet,” said Trent Mueller, Webmaster for Columbia Analytical Services. “People may find it useful to do a quick web search to see if their chemical is on the list, rather than search through the entire Prop 65 document itself.”

The chemicals in the Prop 65 list are known to the state of California to cause cancer or reproductive toxicity. The Safe Drinking Water and Toxic Enforcement Act of 1986, also known as Prop 65, requires that the governor revise and republish at least once per year the list of chemicals known to the state to cause cancer or reproductive toxicity. All businesses in the state must notify Californians about significant amounts of chemicals found in their products, or those that may be released into the environment. California’s Prop 65 list is recognized nationwide as being the standard for which other states aim.

The searchable Prop 65 list is also linked to a broader database containing thousands of analytes, which may also show the chemical formula, its structure, stability, melting point, among other information. To search the list, users may visit http://www.caslab.com/Proposition-65-List/ or go to www.caslab.com and type “Prop 65” in the search.

Columbia Analytical has completed the implementation of the National Council of Air and Stream Improvement (NCASI) Method AQ-S108.01 for the determination of anthraquinone in pulp and paper products.

In response to California’s listing of anthraquinone with Proposition 65, many companies are proactively having their products tested for anthraquinone in advance of the ruling’s effective date. This procedure is currently being performed by Columbia Analytical as written and released by NCASI.

Columbia Analytical has been in consultation with NCASI scientists over the past year in preparation for this action by the state. This preparation enabled Columbia Analytical to be in position to offer the Gas Chromatography/Mass Spectrometry (GC/MS) procedure in time for pulp and paper operations to comply with the regulation.

Columbia Analytical is currently analyzing for anthraquinone in samples for multiple organizations.

For more information on anthraquinone analysis, please contact Jeff Christian at 360-501-3316 or Ed Wallace at 360-577-7222.
