Champ d’application

This standard applies to the collection, storage, and transportation of water quality, sediment, and biological samples in marine environments. It is also applicable to marine waste dumping and dredging material disposal operations. It is mandatory for all entities conducting marine environmental monitoring in China. The standard does not cover specific laboratory analytical methods, which are addressed in other parts of the GB 17378 series.

Exigences techniques

GB 17378.3-2007 establishes the fundamental methods and procedures for marine sample collection. It outlines general principles for sampling representativeness, objective setting, and sample custody to ensure data objectively characterizes the marine environment. Strict adherence to these sampling procedures is essential for valid environmental assessments. For water quality samples, the standard specifies requirements for sampling station layout, temporal frequency optimization, and the selection of sampling devices. It details specific collection procedures for special samples, including dissolved oxygen, heavy metals, and oil, emphasizing contamination prevention from the vessel or equipment. Regarding sediment samples, the standard provides guidelines for station layout consistent with water quality monitoring points. It covers the collection of both surface and core samples, requiring specific field descriptions of color, odor, and biological phenomena. Samples must be stored in appropriate containers, such as borosilicate glass or polyethylene bags, to prevent contamination. For biological samples, the standard focuses on selecting species that accumulate pollutants, primarily mussels and oysters. It defines the criteria for sample age, size, and seasonal collection, along with specific preservation methods like freezing at -10°C to -20°C for different types of marine organisms.

Méthodes d’essai

While this standard does not specify laboratory analytical testing methods, it mandates rigorous field quality control procedures. These include the use of field blank samples to assess environmental contamination during sampling, field parallel samples to determine sampling precision, and field spiked samples to monitor changes during transportation. The standard also details specific evaluation procedures for sampling device performance, including sealing reliability and material inertness.
