Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

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〉

Food is the main way of intake of trace elements by human, and rice is the most important food that Taiwanese eat every day. This research aimed to construct a simple, fast and reliable method to analyze multi trace elements in rice by using inductively coupled plasma mass spectrometer, ICP-MS. Prior to instrumentalanalysis, microwave digestion system was successfully applied to decompositionof samples by using 6 ml of concentrated nitric acid and 3 ml of 30 % hydrogen peroxide under 10 minutes and 110 ℃digestion. To validate the proposed method, three Standard Reference Materials from the National Institute of Standard and Technology,were analyzed, and the recovery of each element was in the range of 80-120 %. The measurement uncertainty was alsoevaluated by top-down approach, and the results are in the range of 0.08-5.08 mg/kg.
Afterwards, 75 rice samples from different regions in Taiwan, 25 different species of fish samples and 42 pork samples were collected as field research samples. Finally, the provisional tolerable weekly/daily/monthly intake of adults and elementary childrenwere estimated. All of the 75 rice samples and 42 pork samples are under the regulation for heavy metals set by Food and Drug Administration. Further speciation method is needed for fish samples to check the concentration of inorganic arsenic and methyl mercury. Average weekly/daily/monthly intake of each element of elementary children is under the regulation set by World Health Organization, but the weekly intake of arsenic and mercury of adults are above the regulation.
