EPA Releases Plan for New Health Risk Assessment for Cobalt
EPA released its draft plan for IRIS cancer assessment for inhalation of cobalt that takes a “no safe-level” approach inconsistent with the consensus from other available studies.

The agency recently released its draft plan for an extensive new health evaluation for cobalt inhalation and will focus its assessment on water-soluble and water-insoluble cobalt compounds.
EPA officials indicated that it plans to carry out a cancer assessment that will likely be more stringent and generate new risk values that could drive additional future restrictions on cobalt use, much like the current hexavalent chromium evaluation under review by the agency.
The agency also recently announced a public meeting in January to discuss several matters related to its approach on inhalation risks from cobalt, including scientific complexities associated with the effort.

Plastics and Plating on Plastics [1944]
This republished 1944 AES convention paper presents an historic perspective of the early days of plastics in surface finishing - using them and plating on them, in the waning years of World War II. The discussion reviews the uses of plastics in plating equipment and processing at that time, as well as the coating of the plastics themselves, with accompanying application photos. You will note that today’s conventional plating-on-plastics processes lay far in the future. Surprisingly, CVD processes are discussed.

A Process for Alkaline Non-cyanide Silver Plating for Direct Plating on Copper, Copper Alloys and Nickel Without a Silver Strike Bath
Traditionally, silver is electroplated in toxic, cyanide-based chemistry. Due to cyanide’s extreme hazard to human health and environments, developing non-cyanide silver chemistry is essential for the silver electroplating industry. Discussed here is an aqueous, alkaline non-cyanide silver plating technology, which can be directly plated over nickel as well as copper and its alloys. The silver deposits have perfect white color and better anti-tarnishing properties than other non-cyanide silver processes. The silver is plated entirely from the dissolving silver anode and the bath is very stable, and maintains a stable pH level both during plating and idle time. This new non-cyanide silver technology will plate bright silver that is perfectly suitable for electronic, industrial and decorative applications. .
