NO This publication describes sampling and sample preparation procedures suitable to obtain uncontaminated samples for the purpose of determining river inputs of inorganic contaminants into estuaries. Emphasis is placed on heavy metal contaminants but procedures are suitable, with appropriate modifications for other inorganic contaminants. For example, the collection of samples for mercury may require modifications of handling procedures.
