Re: leaching of chemicals from pipes and process equipment



What type of pipes are you thinking about?  The pollutants that are
released are different for different types of pipes.  For copper pipe,
its copper.  For galvanized pipe, it is zinc. For stainless steel pipe,
chromium may be released.  For plastic pipes, releases of plasticizers
are of concern.  There are data sources for some of these releases on
the Internet.
