“…In general, emission readings obtained in this study from the ten different points in and around the medical waste incinerator for nitric oxide and ammonia was within the acceptable limits ≤0.06ppm. The readings obtained for hydrogen sulphide in front of the incinerator (0.07ppm) and main electrical station (0.06ppm) exceed the permitted limits and call be linked to construction materials used in the build [15]. Overall, incinerator in this study is functionally useful but could be improved via the integration of a multi-stage combustion chamber and scrubber which both aids in the mopping up of excess fumes as well as prompts complete combustion of waste at higher temperatures.…”

Waste incineration represents a prominent waste treatment strategy applied towards the treatment of hospital waste in many developing countries. Adequate pollution control limits the exposure of waste workers and the community to toxic contaminants in air emissions and ash. This study examined the air quality emissions of acid gases (Nitric Oxide, Sulphur Oxides, Hydrogen Sulphides, Ammonia, Carbon Monoxide, Methane) using a portable Haz-Dust Particulate detection system. Determination of heavy metals (Cadmuim, Chromium, Cobalt, Copper, Nickel, Iron, Lead, Magnesium, Manganese and Zinc) released in the flu ash samples in the neighboring environments at the front and back of the incinerator, including the electrical station and school block around the Federal Government College, Keffi was measured using an Atomic Absorption Spectrophotometer (iCE 3000 series). The results showed that the particulate emissions were in the range of 0.10-0.26 (mg/m 3). Carbon monoxide levels detected were in the range of 5-12 ppm. The distribution of acid gases ranged between 0.01-0.07 (ppm) for CO, SO 2 , NH 3 , H 2 S and NO 2. No measureable concentrations of Chromium, Copper and Lead was detected. The concentrations of Iron (0.202 mg/l) and Magnesium (18.309 mg/l) were below the WHO acceptable limits while Cobalt (0.171 mg/l), Nickel (3.466 mg/l), Manganese (3.589 mg/l) and Zinc (10.61 mg/l) were higher than approved limits. Improvements are required for the medical waste incinerator in this study by integrating addition process treatment systems to reduce environmental pollutants being released.

“…Within the urban ecosystem, soils are distinguished by composition and properties (Short et al, 1986). Natural landscapes are transformed into anthropogenic with a local change in biochemical cycles (accumulation and removal of chemical elements (Adama et al, 2016;Dymov et al, 2013). Urban soils, as a depositing component of the urban landscape, accumulate many trace elements, including heavy metals and metalloids, as well as organic compounds that are toxic to living organisms (Kicińska, 2019).…”

According to the main chemical indicators, the soils of the city differ signifi cantly from their natural analogue. A signifi cant part of the territory of cities is affected by negative processes that affect the ecological functions of soils. Due to the intensifi cation of the anthropogenic impact, surface air pollution increases, soil profi les are disturbed, acidity and alkalinity change, and the biodiversity of soil microfl ora is reduced. This paper presents the results of a study of alluvial urban soils of parks and the industrial zone located in Saint Petersburg in Russia. A morphological description and the basic physical parameters of soils are determined. The content of priority toxicants (heavy metals, benzo[a]pyrene, petroleum products) was conducted, as well as an epidemiological study of soils for the presence of pathogenic organisms. The data obtained show that heavy metals accumulate in alluvial soils, about 35% of the studied soils exceeded permissible concentrations. The content of PAHs in soils also exceeded up to 34 of the maximum permissible concentration. We observe differences in the sanitary and hygienic conditions of alluvial territories specially designated for recreational area. According to the results of microbiological studies, pathogenic organisms are present in soils, but their content varies within acceptable limits of Russian Federation.

“…The 2011 Health Facility Research reported that one in three PHCs did not practice medical waste segregation, and of those who did, almost half reported burning their medical waste in the open area (NIHRD, 2012). These situations entail potential health risks to healthcare workers and community near the PHCs (Adama, Esena, Fosu-Mensah, & Yirenya-Tawiah, 2016;Oyekale & Oyekale, 2017;Udofia, Gulis, & Fobil, 2017). The exposed population increases as healthcare utilisation increases.…”

ABSTRAKPada tahun 2014 Indonesia mulai menerapkan Universal Health Coverage (UHC), yang akan meningkatkan cakupan asuransi kesehatan. Artinya bahwa pemanfaatan layanan kesehatan akan meningkat juga, sehingga pengelolaan limbah medis di pusat kesehatan masyarakat (puskesmas) akan menjadi semakin penting. Artikel ini merupakan analisis data Riset Fasilitas Kesehatan (Rifaskes) yang dilakukan oleh Badan Litbang Kesehatan tahun 2011 tentang faktor-faktor yang mempengaruhi pemisahan limbah dan pembuangan akhir limbah layanan kesehatan di Puskesmas. Jumlah sampel adalah 8.599 Puskesmas. Variabel yang dianalisis meliputi sistem pembuangan limbah, perilaku pemisahan limbah, dan pengolahan limbah dengan cara dibakar. Analisis data dilakukan secara multivariat dengan model logistik biner multivariabel dan regresi multinomial pada tingkat signifikansi 0,05. Hasil analisis regresi multivariabel menemukan bahwa ada ketidaksetaraan berbasis geografis di mana Puskesmas yang terletak di wilayah Jawa-Bali, di daerah perkotaan, bukan di daerah terpencil, dan di pulau-pulau utama, cenderung melakukan pemisahan limbah medis, dan cenderung tidak melakukan praktik pembakaran terbuka. Puskesmas yang memiliki sistem pembuangan limbah yang layak, mengindikasikan bahwa memiliki kecenderungan mempraktikkan pemisahan limbah medis (tidak pembakaran terbuka). Sebaliknya puskesmas di daerah pedesaan, tidak melakukan pemilahan limbah dan cenderung mengelola sampah dengan cara dibakar. Hal ini mengindikasikan bahwa sumber daya untuk menerapkan pengelolaan limbah layanan kesehatan yang tepat di Puskesmas, termasuk fasilitas dasar, pelaksanaan pemisahan di sumber, dan pengolahan serta pembuangan limbah yang tepat menjadi sangat penting. Kata kunci: Limbah medis, fasilitas kesehatan, analisis regresi, pengelolaan limbah, Indonesia ABSTRACTIn 2014, Indonesia started implementing Universal Health Coverage (UHC). As coverage of health insurance expands, healthcare utilisation will increase. Therefore, sustainable healthcare waste management (HCWM) in public health centres (PHCs) will become more important. This paper addresses the drivers of waste segregation and the final disposal of healthcare wastes. We obtained data on health care waste management (HCWM) in 8,599 PHCs from the 2011 Health Facility Research (Rifaskes). We then fitted multivariable binary logistic and multinomial regression models at the 0.05 level of significance. The multivariable regression analyses found that there were geographically based inequalities where PHCs located in JavaBali region, in the urban area, not in the remote area, in main islands, were more likely to practice medical waste segregation, and less likely to practice open burning. Owning a sewerage system corresponds to a higher likelihood of practising medical waste segregation and lower likelihood of open burning. Moreover, PHCs with better basic amenities were more likely to segregate their waste and less likely to practice open burning. This paper recommends the importance of resource for establishing proper ...
