珠江三角洲地区水环境污染特点表现为：污染物排放量大、类型杂且集中，潜在复合污染出现，跨界污染突出，城市污染依然严重，并呈现出从城市向农村蔓延的区域性污染趋势，加上近几年咸潮入侵加剧，使区域水质型缺水的局面更趋紧张。造成这种污染局面的因素：一方面受控于区域内特殊的河网分布格局，水体径流特征、水资源分配的地区性差异以及海潮入侵等自然因素；另一方面也反映了区域经济发展模式，工业布局和城市规划不尽合理，环境基础设施滞后，环境意识淡薄，经济发展与环境保护不协调等人为因素所致。

The effects of NaAA content on the mechanical properties and water-swellable properties were studied. The experimental results show that NaAA has good reinforcement for the EVM vulcanizate. EVM vulcanziate reinforced by NaAA has higher water absorbing rate and equilibrium water absorbing ratio. When the NaAA content is 50 phr, the maximum water-absorbing ratio of EVM vulcanziate is 278.3%. With the incorporation of ion into immersing media, the water-absorption ratio of EVM vulcanizates decreases. FT-IR analysis confirms that NaAA formed in the process of compounding and underwent polymerization during vulcanization.
