Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "In this paper we report the laboratory testing and (more importantly) the field testing of a large volume (200 L) liquid-liquid extraction device (APLE) developed by the Ontario Region, Water Quality Branch and the Engineering Section at CCIW. The device permits the lowering of the detection limits for organic contaminants by two orders of magnitude (100) over conventional I - 2 L volume samples. The extractor is particularly useful in situations like the Niagara River where even though concentrations can be low the large flow can still lead to significant chemical loading (for example a chemical concentration of 1 ng/L in the Niagara River corresponds to a loading of 200 kg/year to Lake Ontario)"--Exec. summary.
