Chemical precipitation and complexation are primarily important for the inorganic species. The formation of coordination complexes is typical behaviour of transition metals, which provide the cation or central atom. Ligands include common inorganic anions such as Cl - , F- , Br - , SO4 2- , PO4 3- and CO3 2- as well as organic molecules such as amino acids. Such complexation may facilitate the transport of metals. Biodegradation is a reaction process mediated by microbial activity (a biotic reaction). Naturally present bacteria may transform the organic molecule to a simpler product, . another organic molecule or even CO2. Biodegradation has wide applicability to. | Sector Guidance NoteDỈPPC Guidance for the Large Volume Organic Chemicals Sector Integrated Pollution Prevention and Control IPPC Scottish environment protection agency ENVIRONMENT AND HERITAGE SERVICE Environment Agency Commissioning Organisation Environment Agency Rio House Waterside Drive Aztec West Almondsbury Bristol BS32 4UD Tel 01454 624400 Fax 01454 624409 Environment Agency First draft published September 2002 This version 2nd draft published April 2003 This document is Environment Agency copyright .
