Biological Pollution in Libraries: A Case Study of the King Abdulaziz Public Libray, Kingdom of Saudi Arabia. American Journal of Information Science and Technology. Vol. 5, No. 2, 2021, pp. 40-47. doi: 10.11648/j.ajist.20210502.14 Received: May 7, 2021; Accepted: May 26, 2021; Published: June 9, 2021 Abstract: Biological pollution is a main problem that threatens the environment because of its great risks that negatively affect human health. Such risk is more increased in closed spaces than open ones. Being closed and insufficiently ventilated environment, libraries are highly liable to biological pollution and they may become fertile environments for the causes of pollution. The present study aims at measuring how extent the biological pollution level is in the King Abdulaziz public library in the Kingdom of Saudi Arabia and how suitable and safe it is as a workplace to librarians and reading place for visitors. It also reveals the librarians' awareness and understanding of biological pollution and its risks. The study uses case study approach and the experimental method to achieve the objectives and answer the questions it raised. It concludes that King Abdelaziz Public library suffers from high air pollution and books may form the most concentrated colonies of bacteria. It finally recommends that environmental factors that help the growth and reproduction of microbes in the internal library environment must be under control, library pollution level must be measured periodically, laws and regulations that maintain a healthy environment for librarians should be enacted and regulated and must be Implemented an environmental management system that contributes effectively to eliminate pollution Keywords: Biological Pollution Risks, Biological Pollution, King Abdulaziz Library, Librarian's Occupational Safety, Public Library 1. Introduction Pollution is an environmental phenomenon that takes a large part of all governments' attention because of its negative impact on the health of individuals. Biological pollution is as old as the human being is on earth [1]. It results from visible and invisible living organisms, whether they are plant or animal [2]. Libraries are institutions that have an integral part of the environment, and they have special importance of intellectual and cultural heritage that should be secured. Therefore, libraries should be environmentally protected and preserved, because the environmental safety of libraries is fundamental to the safety of their users, and librarians. 2. Background Literature Many studies dealt with library pollutants in different areas of the world, however, the intellectual contributions of biological pollution of libraries in Arab countries is still lacking. The following section presents intellectual production of related studies. Dalal et al. traced the extent of fungal contamination of office materials in some libraries in Wardha city, India. The study classified as a type of biological pollution research and its results indicated that many fungi clearly spread in air or books. The study also confirmed that the fungi are primarily responsible for the paper and book damage in libraries, as well as affect significantly the health of librarians [3]. Hayleeyesus and Manaye measured the concentration of
