This study was conducted to determine the amount of information pollution in the Magiran and Noormags databases and to examine the status of information pollution in terms of the content of abstracts, bibliographic information, key words, and the methods of writing.

The research method was an analytical survey utilizing the researcher-designed questionnaire. Inferential statistics were used to analyze the data. The two populations of this research were chosen from the MagIran and Noormags databases. Questionnaires were submitted to all the postgraduate students in Educational Sciences at the Faculty of Psychology of Isfahan University, Iran. There was no sampling.

The findings showed no significant difference in the overall amount of information pollution in the content of abstract, bibliographic information, keywords and the method of writing between the two databases. But overall information pollution in the MagIran is .95 less than Noormags, which is due to the less availability of information pollution in bibliographic information and key words in Noormags.

Abstracts and the writing styles in Noormags are in better condition and there are less information pollution compared to MagIran.

The main purpose of this study is determining the information pollution in data bases shared by the Islamic Azad University, Tehran Science and Research Branch in library Information Retrieval from the viewpoint of postgraduate students and is determining the average information pollution in content of abstracts, bibliographic information, keywords and contamination caused by writing. The methodology in this research is documental and analytical survey. Two societies of research include five database: Emerald, Pro Quest, Science Direct, ISI Web of knowledge, Scopus and graduate students of Library and Information Science, Islamic Azad University, Tehran Science and Research branch. For this study two different questionnaires were used. The findings showed between the mean score of pollution Factors of bibliographic data to separate databases are significant differences. So that Proquest in this category is in the first place. It also was determined. the mean score of pollution factors in the abstract of five databases, is no significant difference database. But ISI Web of knowledge Had little more pollution than others. Comparison of pollution in the keyword information shows the mean scores between pollution factors to separate data bases are no significant different, so that Emerald has more pollution. It also was determined between the mean score pollution factor caused by writing data exists significant difference. So that in this group Science Direct is in the first place. Although these five bases are studied in the humanities, but the results showed each database does not meet all user needs entirely. To reduce pollution using standard thesaurus, fix any spelling mistakes and inappropriate information with competent judgment, reduce the contradictory information, stained bias and biased information, misleading and unfounded is recommended.

With the development of computer networks and increase in the volume of publications, the so-called advent of “Information Revolution” took place. Since controlling publications is a difficult task, publishing wrong or misleading information can result in the contamination of information. Consequently, information pollution can cause contamination in decision-making process, materials and environment.
