Waterbase - TCM: QualityBiotaD

This website has limited functionality with javascript off. Please make sure javascript is enabled in your browser.

The QualityBiotaD table contains disaggregated data on hazardous substances in biota, measured at Eurowaternet transitional, coastal or marine water monitoring stations. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations and Pressure data.

Table definition

Year	Year	year of aggregation period or year in which sample taken, in format YYYY.	int(4)	0
Month	Month	month in which sample taken, values in range 0-12 (it is possible that the month has not been supplied, in which case the value will be 0).	int(4)	0
Day	Day	day in which sample was taken, values in range 0-31 (it is possible that the day has not been supplied, in which case the value will be 0).	int(4)	0
Unit	Unit	unit of measurement.	nvarchar(30)	0
Basis	Basis	basis of aggregate: D = Dry, L = Lipid (fat), W = Wet.	nvarchar(1)	0
SampleID	Sample ID	unique sample identifier required if multiple samples taken on same day. SampleID default value is 0.	nvarchar(50)	0
CASNo	Chemical abstract service number	chemical abstract service number of determinand.	nvarchar(20)	0
Determinand	Determinand	determinand name.	nvarchar(200)	0
DryFreshRatio	Dry fresh ratio	ratio of dry weight to fresh weight of biota monitored expressed as %.	float(8)	0
Fat	Fat	fat content of biota expressed as % of total wet matter.	float(8)	0
LimitOfDetection	Limit of detection	concentration for which there is a desirably small probability (around 5%) that the determinand will not be detected, i.e. there is a 95% probability that the determinand will be detected.	float(8)	0
LimitOfDetermination	Limit of determination	the smallest concentration that can be distinguished from the analytical blank at a chosen level of statistical confidence (usually 95%).	float(8)	0
Concentration	Concentration	concentration of determinand in sample. For observations reported as below the analytical limit, the field will contain the upper (reporting) limit.	float(8)	0
Tissue	Tissue	code of tissue element of species monitored: LI = Liver, MU = Muscle, SB = Soft body, WO = Whole body.	varchar(2)	0
LimitOfDetectionFlag	Limit of detection flag	flag to indicate sample below analytical limit of detection in format <.	varchar(1)	0
CountryCode	Country code	ISO 3166-alpha-2 code elements.	varchar(2)	0
WaterbaseID	Waterbase ID	Internally produced, unique identifier used to represent the transitional, coastal or marine water monitoring station, in the format: CountryCode_WaterDataSet_NationalStationID (e.g. GB_TCM_12345).	varchar(200)	-1
Species	Species	code of species monitored.	varchar(20)	0
