Risk assessment on soil environment quality and losses of nitrogen and phosphorus for the gravel soils under different farming practices in the watershed of Lake Fuxian;

Study on the Effect of 2 Kinds of Emergent Plants in Removing Nitrogen and Phosphorus and Its Influencing Factors;

Inert gas fusion thermal conductivity method for the determination of nitrogen in silicon metal;

An indirect proof of the main source of nitrate and phosphate pollutant in Songhuaba reservoir;

The influence of nitrate concentration on toxin content of Alexandrium tamarense was investigated, which gave rise to the supply of an appropriate nutrition condition and culture technique of increasing the toxin production of Alexandrium tamarense.

Alexandrium tamarense showed the highest specific growth rate at low nitrate level.

Existing forms of phosphorus and nitrogen in sediments of Wabuhu Lake;

Effects of Phytase and Compound Enzymes on Performance and Utilization of Nitrogen and Phosphorus for Meat Chickens;

The nitrogen and phosphorus in sediment interstitial water of cage cultural waters in the Depth Bay of Niutou Island;

Studies on growth and photosynthesis characteristics of Gracilaria lemaneiformis and its capacity to uptake ammonium and phosphorus from scallop excretion;

Simultaneous removal of ammonium and sulfate from synthetic wastewater by anaerobic biodegradation;

The result indicated that ammonium and phosphate were the main factors that influenced the growth of chlamydomonas: the bloom began to occur as the ratio of ammonium and phosphate was 17, and the bloom rapidly regarded when the phosphate deduced to 0.
