Opis:: The abundance of microplastics (MP) in the aquatic environment is increasingly disturbing for maritime countries, especially Indonesia, because it has the potential to threaten the health and sustainability of aquatic ecosystems. This review summarized and discussed the distribution of MP abundance in Indonesian aquatic ecosystems which concluded that rivers, bays and estuaries, beaches, seas, and even fish and shellfish have been contaminated. The highest contamination of MP was found in the waters of Jakarta, West Java, and East Java, which are densely populated areas. The potential threat of exposure and accumulation of MP to human health was also discussed. However, differences in the methods and units of measurement for MP as well as limited information regarding the interaction of MP with human organ functions are weaknesses in this review. The future research on the relationship between food and feeding habits of the community around contaminated waters with the accumulation of MP in the human body is needed to identify the prevention and treatment strategies.

Opis:: The constant discharge of large quantities of toxic substances due to human activities has led to a global environmental issue. Numerous industrial sectors’ effluents, which include coal-based power plants, mineral extraction activities, electroplating processes, as well as battery manufacturing, release metallic ions towards different ecosystems, such as Cadmium (Cd), Mercury (Hg), and Chromium (Cr). Heavy metals pose a significant danger to living organisms, humans, and environments because of their properties, mainly severe toxicity, and strong accumulation ability. Metallic ions are not subject to breakdown towards final components when contrasted with organic contaminants, which are significantly impacted by biochemical and chemical decomposition. Consequently, eliminating these elements has been regarded as a significant task within the water treatment sector. The purpose of this article is to analyze the literature related to heavy metals in terms of different issues. The heavy metals expression is explained. The natural sources and human activities responsible for releasing metallic ions into the environment are comprehensively discussed. In addition, heavy metals toxicity and potential risks to humans and different ecosystems are included. Various approaches for removing heavy metals from industrial wastewater, along with their associated advantages and drawbacks, are further evaluated.

Opis:: Nowadays, one of the most important and essential aspects of having a healthy and safe life is the air safety and its quality in indoor and outdoor environments. In the air, there are not only chemical pollutants but also biological ones, with specific impacts. Hospital environments are among the most likely to be affected by the microbiological contamination of the air; therefore its quality is particularly important. Pathogenic microorganisms, which may be present in the air, can cause nosocomial infections in hospitalized patients, with compromised immune system or other medical conditions. This paper reflects the evaluation of microbiological air contamination, in different hospital environments and nearby areas, in the city of Tirana. The microbial air quality has been monitored during the period of 2009–2018, performing evaluations every three years, in the same area and the same time of the year. In order to build a database for understanding the impact of developmental changes on the air microbiological loads, results of similar studies conducted earlier, during 2007 and 2008 were also taken into consideration. The above-mentioned period was selected because of the changes in the infrastructure and indoor environments of the monitored area, where many patients have been treated for years. Changes have been made over the years to hospital structures and surroundings, including recreational facilities, clinical service units, as well as main and connecting roads, etc. The obtained results, which were compared over the years, provided a clear view of the changing microbiological air loads, influenced by the improvements of indoor and outdoor areas. The morphological studies of the observed, isolated, purified and identified microorganisms revealed the presence of specific mold loads, with the dominance of the species of Aspergillus genus and those of the group Fungi imperfecti. Over the years, a decrease in the total number was observed (from 103 to 101), together with a smaller number of bacteria (1012), in the monitored environments.
