Using RUA as a starting point, establishing a PRTR in line with good international practice and with public access to the information collected should be a medium-term priority for Colombia. Policies and best practices of OECD countries could support these efforts (OECD, 1996a, 1996b,). Colombia could benefit from a wealth of information on country data and experiences and OECD-wide agreed release estimation techniques provided by the OECD website.4 This information could assist greatly in launching a PRTR in Colombia. To date, however it has a limited focus, dealing only with chemicals covered by the Stockholm Convention on Persistent Organic Pollutants (POPs). Colombia should strengthen its policies concerning public availability of safety data on chemicals. To this end, practices followed by OECD countries and reflected in two OECD Council Acts (OECD, 1983b, 1983c) could be of benefit.
