| Abstract: | Phosphorus(P) is an essential nutrient utilized by all organisms for energy transport and growth. Both the conventional molybdenum-blue method and the magnesium-induced coprecipitation(MAGIC) procedures were applied for the measurement of dissolved inorganic phosphorus(DIP) and total dissolved phosphorus(TDP) in more than 840 water samples collected between 2003 and 2005,including seawater(the Huanghai Sea,the East China Sea,and the northern South China Sea) ,water from rivers and estuaries(the Changjiang,t... |
