Materials and methods Selection of the test site and collection of test samples Select a gully from the upper reaches of Yitong River in Changchun City.
Aquatic plants can directly absorb NH4+,NO3- and PO43- in waters, and assimilate them into materials for their own needs.
Microorganisms play a very important role in circulations of materials and energy in the ecosystem of the gully.

Introduction Polyurethanes (PUs) are a very large and varied family of extraordinarily versatile and useful engineering materials.
The structures of raw materials, i.e., isocyanates or alcohols, are an important factor to affect the urethane reaction kinetics.
For example, Yilgor et al. [5] reported that the symmetry of isocyanate greatly impacts the thermal behavior and weaving structure of materials.
