CODE LIST FOR CHEMICAL, PHYSICAL, BIOLOGICAL AND MICROBIOLOGICAL DETERMINANTS MEASURED IN ENVIRONMENTAL RESEARCH
1 Preface
The Finnish Environment Institute, the Swedish Environmental Protection Agency and the Institute of Applied Environmental Research of the Stockholm University have developed this code list from a list originally created by the Nordic Code Centre. Abbreviation 'Determinants, Code List DB' is used then refering to this list.
2 Structure
Code List DB consists of three different sub-codes: substance, pre-treatment and determination.
Substance code list is divided into five sub-groups:
- Inorganic substances
- Organic substances
- Physical parameters
- Biological parameters
- Microbiological parameters
The main purpose of this code list is to simplify data handling of physico-chemical determinants and they carry sufficient peripheral information about data quality for data users. They are not unambiguous if the main interest is analytical method. Codes in the Code List DB are not specific for units. These should be documented separately in the data bases.
3 Maintenance
Maintenance of the code list is continuous. New codes are added into the code list on the basis of the requests made by the users. Proposals for the new codes should be sent using the code request form. A new code can be taken in use, with the list designator DB, only after it has been accepted by the maintainer (Finnish Environment Institute, SYKE) of this code list.
The basic idea in the maintenance of the code list DB is that changes which could change the basic meaning of the code will not be made. Codes with the list designator DB are stable and unique.
Code requests will be automatically sent to the SYKE. Decisions on these requests will be made in co-operation with the SYKE and the Swedish Environmental Agency.

GCA Gas chromatography, atomic emission spectrometry
GCE Gas chromatography, electron capture
GCF Gas chromatography, flame ionization
4.4. Code combinations
Examples how sub-codes are combined.
The accuracy of the codes can be selected freely depending on needs. Pre-treatment and/or determination codes can be missing. If several pre-treatment codes are included in the code combination, the order of these codes is the same as the order of the different pre-treaments during analyse.
Description of the code combination is composed by means of the names of the codes included in the combination (see examples below).

Code lists updated 30 September 2020. Please note that only DB codes are included in substance list, additional IM codes are also used in the ICP IM programme included in separate file 'Parameter codes on IM list' . Also a list including all Parameter codes (DB and IM) used for individual Subprogrammes is added 'Parameters for each Subprogramme'.
