text: The SQT approach has been praised for a variety of reasons as a technique for characterizing sediment conditions. Relative to the depth of information it provides, and the inclusive nature, it is very cost effective. It can be applied to all sediment classifications, and even adapted to soil and water column assessments (Chapman and McDonald 2005). A decision matrix can be employed such that all three measures be analyzed simultaneously, and a deduction of possible ecological impacts be made (USEPA 1994)
  Other advantages of the SQT include information on the potential bioaccumulation and biomagnifcation effects of contaminants, and its flexibility in application, resulting from its design as a framework rather than a formula or standard method. By using multiple lines of evidence, there are a host of ways to manipulate and interpret SQT data (Bay and Weisberg 2012). It has been accepted on an international scale as the most comprehensive approach to assessing sediment (Chapman and McDonald 2005). The SQT approach to sediment testing has been used in North America, Europe, Australia, South America, and the Antarctic.
