Parameter Code / Full Name or Description of Parameter / Field Unit Field Name WCZ Name of Water Control Zone WCSZ Name of Water Control Sub Zone dd/mm/yyy RIVER Name of River MDATE Date of Sampling STATNAME Name of Sampling Station Mathematical expressions for the parameters L_*: L_* i) '<' means smaller than the value indicated; ii) '>' means larger than the value indicated; (e.g. L_DO, L_PH_F, iii) 'blank' means equal to the value indicated L_SS, etc.) Example L_SS is 'blank' and SS is '5.8', mean the suspended solids level of the river water sample is equal to 5.8 mg/L.

L_E_COLI is '<' and E_COLI is '1', mean the E.coli content of the river water sample is less than 1 cfu/100 mL. DO* Dissolved Oxygen mg/L PH_F* pH SS* Suspended Solids mg/L BOD5* 5 days Biochemical Oxygen Demand mg/L COD* Chemical Oxygen Demand mg/L OIL* Oil and Grease mg/L F_COLI* Faecal Coliforms cfu/100mL E_COLI* E.Coli cfu/100mL NH4* Ammoniacal Nitrogen mg/L NO3* Nitrate Nitrogen mg/L TKNSP* Total Kjeldahl Nitrogen (Soluble + Particulate) mg/L PO4* Ortho-phosphate mg/L TPSP* Total Phosphorus (Soluble + Particulate) mg/L SSP* Sulphide (Total) mg/L AL* Aluminium g/L CD* Cadmium g/L CR* Chromium g/L CU* Copper g/L PB* Lead g/L ZN* Zinc g/L FLOW_SUM Flow m3/S SHENZHEN
