DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In this study, naphthalene（Nap）and phenanthrene（PA）were used as target contaminants to investigate the bioavailability of contaminants in sediments with different organic contents under aerobic or anaerobic conditions. The actually total amount of Nap or PA biodegaded was used to compare the total amount of Nap and PA estimated by SPME process with different operating conditions in realistic sediments.
  Results showed that an increase in the organic contents in sediment increased the partitioning of naphthalene and phenanthrene into the organic matters in the aerobic and anaerobic condition. Desorption of target contaminants was the rate limiting factor which decreased the degradation rate and the amount of Nap and PA biodegraded. In the multi-contaminants experiment, naphthalene would be preferentially biodegraded in comparison with phenanthrene. The experiment results indicated that the presence of Nap could enhance the biodegradation of PA in the anaerobic condition.
  For the assessment of Nap biodegradation, SPME could more preeiously estimate its biodegradation potential. However, the LMW PAHs, such as PA, SPME might underestimate its biodegradation protential. The biodegradation of naphthalene, SPME could provide the better assessment and was not affected by sediment organic content or aerobic and anaerobic condition.
  It implied that desorption rate and biodegradation rate affected the SPME assessment. Therefore, SPME could not preciously predict the bioavailability of Nap or PA in sediment, especially, when the system contained multi-contaminate with various biodegradability.
