NASF TECHNICAL PAPERS EDITED BY DR. JAMES LINDSAY, NASF TECHNICAL EDITOR 14 NOVEMBER 2015 — pfonline.com The surface fnishing industry joined the Nickel Institute, the American Chemistry Council and more than a dozen other trade associations in October in submitting comments to the State of California over its proposed listing of nickel metal under Proposition 65 as a reproductive and developmental toxicant. Because the listing is the frst time nickel metal itself is being considered as a reproductive hazard, both NASF as well as its California leadership are working together in monitoring the state's review process by the Ofice of Environmental and Human Heath Assessment (OEHHA). The industry coalition's letter supported the scientifc comments on the proposed listing that were submitted by Dr. Hudson Bates, executive director of the Nickel Producers Environmental Research Association (NiPERA), and Dr. Julie Goodman of the consulting frm Gradient and the Harvard Chan School of Public Health. The OEHHA will hold a scientifc meeting on the issue on November 9, 2015, in Sacramento. Industry representatives will be in attendance. Following is a brief excerpt from the letter, addressed to Michelle Robinson of the Ofice of Environmental Health Hazard Assessment: REGULATORY UPDATE NASF Submits Comments to California on Proposed Prop 65 Listing of Nickel Metal RE: 2015 DART Prioritization of Metallic Nickel The undersigned organizations support the scientifc comments submitted under separate cover by the Nickel Producers Environmental Research Association and emphasize the following key points, in particular: • Excluding occupational settings, exposure to metallic nickel (CAS# 7440-02-0) via inhalation or the oral route is negligible or non-existent. Similarly, despite dermal exposure to metallic nickel in some consumer items, dermal absorption is very low and the contribution of this exposure route to systemic blood nickel levels is undetectable. • The current proposal for prioritization of nickel was based on the new epidemiological studies available since 2007. The case- control studies of workers at the Monchegorsk nickel refnery stand out due to the high external and internal nickel exposures of the workers (many fold higher than any ambient air study) and the studies' ability to detect potential causal exposures related to reproductive outcomes. Yet, these studies do not support a causal association between exposure to nickel and adverse reproductive outcomes. In total, the undersigned organizations urge OEHHA and the DARTIC to assign metallic nickel a low priority. The Best of the Best Until a few years ago, the NASF and its predecessor societies published a journal under a number of titles, most recently Plating & Surface Finishing. Included were hundreds of tech- nical papers that served as the basis for advances in all forms of surface fnishing. Emphasis was placed on selecting the best paper each year— the Gold Medal. It underwent several name changes, being named for fnishing pioneer Carl Huessner in the 1950s, and more recently all awards were given out in honor of Dr. Abner Brenner, another pioneer in our industry. By any name, the Gold Medal papers were the best of the best. In this and coming months, a number of these papers will be republished. Many remain current and useful today. With each decade, the reader will capture the essence of the times in which they were written. This month, the papers from the middle 1950s and 1960s are featured. The Study of Copper Anodes in Acid and Cyanide Plating Baths Charles L. Faust & William H. Safranek, Battelle Memorial Institute, Columbus, Ohio, USA In the middle 1950s, the country was a decade beyond the World War II, and industry was gearing up from military to civilian manufacture. Things were booming, and commercial plating was growing by leaps and bounds. In those days, the auto industry comprised the largest segment for metal fnishing. Basic improvements to the plating process were coming daily for every segment of the plating operation. It wasn't just new chemistries. Improvements in all aspects of the equipment were emerging, including anodes. The AES Carl Huessner Gold Medal paper by Faust and Safranek dealt with anodes. Highly pure Oxygen-Free High Conductivity (OFHC) copper anodes had been developed that ofered signifcant improvements in the eficiency of the copper plating process. These Battelle scientists published their work on evaluating these materials. The paper can be accessed and printed at short.pfonline.com/NASF15Nov1. The Adhesion of Electrodeposits to Plastics Edward B. Saubestre, Lawrence J. Durney, Juan Hajdu & Edwin Bastenbeck, Enthone Inc., West Haven, Connecticut, USA By the 1960s, the surface fnishing industry had grown greatly, with productivity and quality enhanced on all fronts. The auto industry remained the largest segment but others were growing rapidly, particularly in electronics. Yet decora- tive plating remained the most familiar application to the consumer, as evidenced by the vehicles of the day literally NASF REPORT
