United Nations Globally Harmonized System

The United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) includes an internationally standardized guidance procedure on Transformation/Dissolution Protocol (T/DP) for metals and sparingly soluble metal compounds (United Nations, 2007), recently validated by the OECD (Organization for Economic Cooperation and Development). To establish the acute aquatic hazard classification level of a metal-bearing substance under the GHS, data from the T/DP are compared with an acute ecotoxicity reference value (ERV) derived under conditions similar to those of the T/DP.

The Globally Harmonized System of Classification and Labelling of Chemicals (CHS) Presents a brief overview of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) for defining and communicating hazard information and protective measures related to the physical, health, and environmental risks of chemicals through product labels and safety data sheets (SDSs).

The analyses are performed using the criteria in the European classification and labelling directive (67/548). These criteria will be replaced by a new directive that is based on the Globally Harmonized System (GHS) for classification and labelling developed by the United Nations (Reg. 1272/2008). The new rules will be implemented stepwise from June 2010 to June 2015.
