Glossary Germany, Iceland, Ireland, Luxembourg, The Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom, together with the European Union. Overpotential Voltage difference between a half-reaction's thermodynamically determined reduction potential and the potential at which the redox event is experimentally observed. In an electrolytic cell the overpotential leads to the consumption of more energy than thermodynamically expected to drive a reaction. PAH Polycyclic Aromatic Hydrocarbon. PARCOM Commission of the Paris Convention for the protection of the North-East-Atlantic from pollution derived from land-based sources. This convention and another one, the Oslo Convention, were unified, updated and extended in 1992 resulting in the OSPAR Convention for the protection of the marine environment of the North-East-Atlantic. PCB Polychlorinated Biphenyl. PCDD Polychlorinated dibenzo-p-dioxin. PCDF Polychlorinated dibenzofuran. PCN Polychlorinated naphthalene. PEMFC Proton Exchange Membrane Fuel Cell. Plant Installation. PMA Polymer Modified Asbestos. Pollution Direct or indirect introduction, as a result of human activity, of substances, vibrations, heat or noise into air, water or land which may be harmful to human health or the quality of the environment, result in damage to material property, or impair or interfere with amenities and other legitimate uses of the environment (Industrial Emissions Directive). Potash Salts that contain potassium in water-soluble form. In this document, potash refers to potassium chloride (KCl). PTFE Polytetrafluorethylene. PVC Polyvinyl chloride. Rectiformer Combination of a rectifier and transformer designed and built as a single entity for converting alternating current into direct current. Site Geographical location of an installation. A specific site may be used by other operators and/or installations. WORKING DRAFT IN PROGRESS Site remediation Containment and/or decontamination of contaminated environmental media such as soil, groundwater, sediment or surface water from an industrial site. The area of the site may be larger than the fenced area. Standard conditions Reference point of a material used to calculate its properties. In this document, the standard conditions refer to a temperature of 273.15 K and a pressure of 1 bar. Sylvinite Mineral composed of a mechanical mixture of sylvite (KCl, or potassium chloride) and halite (NaCl, or sodium chloride). 320 December 2011 TB/EIPPCB/CAK_Draft_1
Glossary Technique Ensemble of both the technology used and the way in which an installation is designed, built, maintained, operated and decommissioned (Industrial Emissions Directive). TEQ Toxic Equivalent. The TEQ is a single figure resulting from the sum of the products of the concentrations of individual PCDDs, PCDFs and PCBs and their individual Toxic Equivalent factors. TOC Total Organic Carbon. TWG Technical Working Group. UNEP United Nations Environment Programme. VCM Vinylchloride monomer. WORKING DRAFT IN PROGRESS TB/EIPPCB/CAK_Draft_1 December 2011 321
