Industrial pollution has been a problem in certain areas of hong kong, and 12 parameters relating to metals and metalloids were initially used in 1986 to measure the degree of such pollution. these parameters are aluminium, arsenic, boron, cadmium, chromium, copper, iron, mercury, manganese, nickel, lead, and zinc. in 1997, another seven were added antimony, barium, beryllium, molybdenum, silver, thallium, and vanadium, making a total of 19
香港部分地區多年來一直受工業污染的困擾， 1986年河溪水質監測計劃推行初期我們用12項金屬及準金屬參數來檢驗工業污染水平：鋁砷硼鎘鉻銅鐵汞錳鎳鉛及鋅其後在1997年起另添加了七項新參數：銻鋇鈹鉬銀鉈及釩，監測的參數共19項，此外並測試了四項與工商業污染有密切關系的參數，即氰化物總量氟油脂及洗滌劑。 -
