Soil - ecosystem has done much with the stability of agriculture , recently the facts influencing the function of soil - ecosystem were not restricting in polluting from physical or chemical sources , the gm technic applying in agriculture not only made the pumping harvest in agriculture , but produced the more serious harm : transgenic bio - pollution 摘要土壤生态系统的功能是否正常直接关系到农业系统的稳定，影响土壤生态系统功能的因素已经不是局限在化学物理污染上了，农业转基因技术的应用，为农业生产带来新的增长点，为消除传统的化学物理污染的同时，也给土壤生态系统带来了更深刻，难以控制的影响因子：转基因生物污染。
This paper with indoor environment as research content , make more detailed exposition from hot comfortable environment , hearing environment , visual environment and air quality aspects for the physical pollution , chemical pollution , biological pollution and radioactive pollution that affects indoor environment 本文以室内环境为研究对象，分别从热舒适环境、听觉环境、视觉环境和空气品质四个方面对影响室内环境的物理污染、化学污染、生物污染和放射性污染做了较详细的论述。
The related reports said the main pollution sources of serious environmental cd , pb and as pollution in china were mining and smelting of nonferrous metals , these pollutants were discharged into the environment and caused the pollution of water , atmosphere , soil and biological species and caused a series of acute and chronic diseases in the exposed people , but the relationship between malignant tumors and environmental cadmium , lead , arsenic pollution is not well understood up to now 研究认为有色金属镉、铅、砷对人体有毒害作用；有色金属矿山的开采和冶炼是环境镉、铅、砷污染的主要来源；污染物进入环境后，产生水污染、大气污染、土壤污染和生物污染，继而危害暴露人群的身体健康，产生一系列急性和慢性病症。
