  sediment environment
Fifteen sponges were collected, preserved (killed with the structure and morphology maintained) and then replaced in a high sediment environment next to a living specimen (at 24?m).
      
In this study, a landscape-ecology approach was applied to a marine soft-sediment environment to examine rates of predation and transfer of secondary production in and around vegetated habitats.
      
These results suggest that this 37 MDa plasmid could be implicated in the adaptation to sediment environment.
      
Macrozoobenthos might affect the sediment environment mainly through bioirrigation, bioturbation, secretion, and digestion.
      
Thus, Ba and Sr must either exist on the surface of tephra particles in volatile and water-soluble compounds and/or were released by weathering from Ba and Sr containing feldspars (originating from pumice) in the cave sediment environment.

Developing marine sediment environmental quality criteria is the prerequisite for formulating its environmental quality standard. About 20 years'overseas study has established a series of effective approaches in this field. Each of the approaches has its own advantage and can be supplemental to each other.

Developing marine sediment environmental quality criteria is the prerequisite for formulating its environmental quality standard. About 20 years'overseas study has established a series of effective approaches in this field. Each of the approaches has its own advantage and can be supplemental to each other. The Apparent Effects Threshold (AET) method, which is considered as possessing potentialities, is an approach through which comprehensive sediment quality threshold is determined by processing the combination of large quantity in situ data and laboratory data. The principles used and the techniques and relevant to AET method is introduced and discussed in this paper.

海洋沉积物环境质量基准的建立是制定其质量管理环境标准的前提.国外近20年的研究已逐步建立起一系列有效的沉积物环境质量确定方法.这些方法各有所长,可以互为补充,其中表观效应阈值法(AET法)正在受到重点关注.这种方法结合了现场实际与实验室确认两方面的大量可靠数据,综合判定沉积物的质量阈值,有很大的发展潜力.本文对此方法进行了综合讨论.

The oil standard employed in the marine environmental monitoring in Chinasince 1980’s is introduced. In the light of the problems from the establishment of “the environmental quality standard of marine sediment”and“the oil standard of pollutant assessment for ma-rine lives”,and the amendment of “the standard of seawater quality”and proceeding from the actual data of the experiment,when the oil standard is made or changed,great attention should bepaid to the choice of the standard samples,the analytical procedure...

In the light of the problems from the establishment of “the environmental quality standard of marine sediment”and“the oil standard of pollutant assessment for ma-rine lives”,and the amendment of “the standard of seawater quality”and proceeding from the actual data of the experiment,when the oil standard is made or changed,great attention should bepaid to the choice of the standard samples,the analytical procedure and the determinationmethod,because these factors affect the quantitative value significantly.

文中介绍了我国八十年代以来已经颁布实施的海洋环境样品分析测试中油标准,针对目前我国制定“海洋沉积物环境质量标准”、“海洋生物体内污染物评价标准”,修改“海洋水质标准”等问题,从实验实际数据出发,阐述在制定或修改油类标准时,必须注意标准油、标准物、分析测定条件、分析测定方法,因为这些因素对量值造成了重大影响

A river kind of sediment Certified Reference Material (CRM) based on natural-matrix for environmental radioactivity has been developed. Nine natural and artificial radionuclides in the CRM were certified by two or more laboratories with one or more methods. The sample preparation, homogeneity test, stability inspection and the methods and results for radionuclide certification are described.
