The following definitions and acronyms have been used in this study:
CRT - Cathode Ray Tube, as in TVs and computer monitors.
EEE - Electrical and electronic equipment.
Hazard - property or situation in which particular circumstances can lead to harm.
Hazard Identification -determines what can go wrong by identifying a set of circumstances.
PCBs - Printed circuit boards (not Polychlorinated Bi-Phenols).
Probability -mathematical expression of chance (e.g., 0.2 is a 20% or one in five chance). Often not calculable and can only be expressed qualitatively (e.g., possible/likely).
PWB - Printed wiring board.
Regulation -The term 'regulation' is used in its broadest sense, being voluntary or mandatory mechanisms, legislation or formal initiatives of government or peak industry bodies.
Risk -a combination of the probability, or frequency, of occurrence of a defined hazard and the magnitude of the consequences of the occurrence.
Risk Assessment -consists of risk estimation and risk evaluation.
Risk Estimation -is concerned with the outcome or consequences of an intention taking account of the probability of occurrence. It includes predicting how likely it is that a set of circumstances will occur.
Risk Evaluation -is concerned with determining the significance of the estimated risks or tolerable level of risk for those affected: it therefore includes the element of risk perception.
RoHS -European Union Directive on the Restriction on the use of certain Hazardous Substances.
TCLP - Toxicity Characteristic Leaching Procedure, US precautionary-based test to assess maximum leachate. If the leachate produced using the TCLP contains certain elements at concentrations above a regulatory threshold, the solid waste is a TC hazardous waste (unless otherwise excluded). The TCLP analysis simulates landfill conditions. Over time, water and other liquids percolate through landfills. The percolating liquid often reacts with the solid waste in the landfill, and may pose public and environmental health risks because of the contaminants it absorbs. The TCLP, or Toxicity Characteristic Leaching (not Leachate) Procedure is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid, and multiphase wastes.
US EPA - Environmental Protection Agency, USA.
WEEE - Waste electrical and electronic equipment.
