|Subject||Less than 2 Hex Chrome Cancer Cases in California (Annually)|
It would be nice if there were a reliable source of data from which to perform these calculations. See my previous comment(s). But using the data we have... The California population is around 40 million. So using the most recent CARB data that show a cancer case rate attributable to hex chrome of 16 per million, that computes to 640 cancer cases from hex chrome annually statewide. See my source here - https://www.arb.ca.gov/adam/toxics/statepages/cr6state.html How many of those are from chrome platers? CARB's Appendix B states chrome platers emit 0.90 pounds of hex chrome annually. SC AQMD states that there are 0.8 pounds per day of Hex chrome emissions in the South Coast basin (see data in SC AQMD MATES V Table 3-4) from all sources. That computes to 292 pounds annually (0.8 X 365 = 292). So in the South Coast area chrome platers make up 0.3% (0.9 / 292 = 0.0031) of the hex chrome emissions in the area that everyone would agree contains the highest percentage of chrome platers in the state. So, since chrome platers make up 0.3% of emissions we can compute the cancer cases attributable to chrome platers as 1.98 cases per year. 1.98 CANCER CASES PER YEAR IN CALIFORNIA FROM HEX CHROME ATTRIBUTABLE TO THE ENTIRE CHROME PLATING INDUSTRY!! Who is in control of CARB? What is the agenda? Setting priorities is one of the most basic functions of management. CARB has spent three years on this rule making.
