1 Scope

This part of HY/T 147 specifies the analysis methods for monitoring items in marine atmospheric total suspended particulate matter samples and precipitation samples.

This section applies to the analysis and testing of atmospheric total suspended particulate matter samples and precipitation samples in coastal waters, offshore and open seas.

3 Terms and definitions

The following terms and definitions defined in GB 17378.1 and GB 17378.2 apply to this document.

Total suspended particulate; TSP the general term for particles suspended in the air with an aerodynamic equivalent diameter below 100µm, referred to as TSP.

Precipitation wetdeposition Liquid water and solid water falling into the underlying surface (land, water surface, etc.) from the atmosphere, including rain, snow, hail, fog, etc.

Sample membrane A filter membrane containing total suspended particulate matter in the atmosphere.

4 General rules

4.1 The concentration of total suspended particulates is determined by the gravimetric method, see GB/T 15432.

4.2 The electrode method is used to determine the conductivity of precipitation, see GB/T 13580.3.
