Methods for the Determination of Chemical Substances in Marine and EstuarineEnvironmental Samples

摘要

The manual contains seven methods for the determination of nutrients, threemetals, and chlorophyll a in marine and estuarine environmental matrices. Two of the metals methods are graphite furnace atomic absorption techniques and the third uses inductively coupled plasma mass spectrometry. Methods for the determination of orthophosphate and nitrite plus nitrate are based on well-established automated colorimetric techniques. Both of these methods have undergone multilaboratory validation study. A high temperature combustion method for the determination of particulate carbon and nitrogen in water and sediments is also contained in the manual. The chlorophyll a method is based on a well-established fluorometric technique.
