聚乙烯醇对环境影响的研究进展

Development on Environmental Influence of PVA

介绍了国内外关于聚乙烯醇的毒性、对土壤环境影响及对水环境影响的最新研究成果。研究表明,聚乙烯醇的毒性非常低,可改善土壤物理性质,促进作物生长,在废水中可回收等特性。正是由于聚乙烯醇对环境的低影响,使聚乙烯醇的溶解性和生物降解性在工业和商业中被广泛应用。文中对PVA的生物性能和环境性能作了较系统的介绍。

This paper introduces the biologic and environmental properties of PVA. The research findings indicate that PVA has very low toxicity and can improve the physical properties of soil so that growth of plants can be prompted; that PVA can be recovered from wastewater. Because of its effects upon the environment, the properties of PVA-solution and bio-degradation are widely applied in industry and commerce.
