Under the rapid development of Phnom Penh, the pollutants control from different sources intothe main natural wetland, Tamouk lake is consequentially required for its ecosystem as well as thesustainable development. Therefore, this work aims to investigate the distribution of thepollutants from the urban canal and aquaculture farm to Tamouk lake through the analysis ofwater quality in both dry and rainy seasons. Twelve sampling sites, i.e., two from urban canals, onefrom aquaculture farm, and nine from the investigated lake, were selected for their water qualityassessment. As the results from both seasonal analyses, the maximum concentrations of totalsuspended solids (TSS), chemical oxygen demand (COD), and ammonia (NH3+) of the effluentfrom aquaculture farm and urban canal to the lake range of 107-134 mg l-1, 76-184 mg l-1, and 8.5-14.9mg l-1 in the dry season and 105-263mg l-1, 75-140 mg l-1, and 7.5-9.2 mg L-1in the rainy season,respectively. In addition, TSS and COD in the lake were only 72-93 mg l-1and 46-77mg l-1 of bothseasons, respectively, whereas NH3+ was estimated to be 7-14 times lower than that in urban canaland aquaculture farms. According to the result analysis, the lakeâs water pollution was mainlycontributed by the discharge from the urban canal and aquaculture farm in both seasons. Higherrelease of pollutants from many sources during the rainy season could compensate for rainwaterâsdilution effect, resulting in the high remaining of organic and nitrogen in lake water. Hence, toreduce the risk of the lake water to humans and ecosystems, the effluent from aquaculture farmsand urban water is highly suggested to have a proper treatment before discharging to the lake.

Biomedical waste management (BMW) is in the spotlight due to the enormous impact of theCOVID-19 pandemic on public health and hospitals. Further, countries with large populationsgenerate significantly higher amounts and variety of both hazardous and non-hazardous BMW,leading to a need for a comprehensive strategy for effective BMW management. The improper,unscientific disposal of BMW causes environmental pollution and presents a continuing,significant health hazard to the individual and the community. The present study provides acomprehensive assessment of the various types of BMW generated and critiques their currentdisposal strategies. A detailed appraisal of current, in-place BMW management guidelines fromvarious world organisations is presented, and emerging protocols for BMW disposal during theongoing COVID-19 pandemic are assessed. Finally, new state-of-the-art technologies, which canlead to breakthrough improvements in various stages of BMW generation, collection, treatmentand disposal process, are examined. The secondary applications of BMW are highlighted, andrecommendations for enhancing the BMW lifecycle practices are presented.

Plastic waste is a problem that has the potential to pollute the environment and can be asource of problems for waters. Microplastics that enter the waters will enter the water body and will eventually settle in the sediment. This study aims to determine the abundance based on the type, size, color and number of microplastics, to determine the comparison of the abundance of microplastics in sediments at each station and to determine the abundance of microplastics based on the pollutant source, to make a distribution map of the presence of microplastics in the Selorejo Reservoir and to analyze the abundance of microplastics based on pollutant sources in the area. Selorejo Reservoir. The results of the study revealed that in the Selorejo Reservoir sediment the most dominant type of microplastic was fragment (42%), based on color it was black (46%), and based on size was microplastic with a size of 125-250 m (48%). Overall the abundance of microplastics in the Selorejo Reservoir is 56637.5 particles/kg sediment where the abundance is high on grid 8 where the grid is the outlet of the Selorejo Reservoir. The results of the Fourier Transform Infrared (FTIR) analysis on sediment samples showed several polymers, namely polyethylene (PE), polystyrene (PS), polyprophylene (PP), and polyamide (PA) ornylon.

Wood carving is one of the oldest traditional professions with a history of hundreds of years andhas developed to this day. The environment of craft villages has its own characteristics because theproduction area and the living area are located in the same household. Wood carving is ameticulous, labor-intensive job, characterized by the use of high-damage equipment such as saws,planers, chisels, hammers, nails, etc., and heavy materials. This exposes workers to many risks dueto the nature of the job or the working environment. Woodworking activities are mostly done bypeople in the village and some surrounding areas. The construction of a database on theenvironment and occupational accidents and diseases related to wood carving is still limited. Inthis study, we analyzed the characteristics of the working environment and the risks ofoccupational accidents that workers have to bear in wood processing in La Xuyen craft village,Vietnam. Within the scope of the study, a total of 377 employees were surveyed using the surveymethod.

In the present study, cigarette smoke exposure shows significant alterations on blood parametersviz., Total Erythrocyte counts (TEC), Haemoglobin concentration (Hb.con.), packed cell volume(PCV), Erythrocyte Sedimentation rate (ESR), Total leukocyte counts and platelets count in albinorats. These changes may be due to the oxidative stress and inflammatory responses induced bycigarette smoke on haematopoietic system. Cigarette smoke consists of carbon monoxide andnicotinamide, which are toxic gases having the capacity to binds with the haemoglobin in redblood cells and interferes with the bodyâs ability to supply inadequate oxygen to the tissues thatacts as a stimulus for marrow production in the result of hypoxic polycythemia and also inducedan irritated action of tobacco smoke on the respiratory tract which causes leukocytosis in albinorats. While after supplementation of antioxidant vitamin C, which reduces the toxicity generatedby cigarette smoke to a maximum extent. This is due to the antioxidant defence mechanism ofvitamin C, which mitigates the toxic actionof cigarette smoke in albino rats.

Leaf surface of plants acts as a sink for the deposition of air pollutants in the urban environment andis considered an ecologically sustainable cost-effective strategy to mitigate the impact of air pollution.In this context, assessment of air pollution tolerance index (APTI) and anticipated performanceindex (API) was calculated to observe the tolerant potential of fifteen plant species along roadsideof Kathmandu valley. APTI was determined by combining the four biochemical and physiologicalparameters; Relative water content (RWC), Total chlorophyll content (TChl), Ascorbic acid content(AA) and Leaf extract pH using a pre-defined formula. Results suggested that, TChl and pH werelower, and RWC and AA were higher at heavily polluted area in comparison to the control site. TheAPTI for the species ranged between 7.57 and 11.51, ideal for sensitive species category (APTI < 16),and the plants are classified as bio indicators of air pollution. Highest mean ATPI (11.51) wasrecorded in Callistemon citrinus and lowest (7.57) was recorded in Buddleja asiatica. The API notonly takes APTI into consideration but also the biological and socio-economic aspect of the species.The API grade indicates. Ficus religiosa and N. arbor-tritis (API = 5) as good performers whileCallistemon citrinus (API=4), Nerium oleander (API=3), Bougainvillea glabra (API=3) and Buddlejaasiatica (API=3) are predicted to be moderate green belt performers. On the basis of APTI and APIassessment, the study suggest that out of fifteen species, only six plants species were identifiedas suitable green belt development. The overall results highlight the suitability of APTI and APIas simple, inexpensive, and convenient methods for recommending plant species for urban areaswith sound environmental pollution with dust load.

Ten surficial sediment samples were collected from 10 locations in Al-Dalmaj Marsh area, whichis located within Al-Qadisiya- Wasit Governorates. The sediment samples were analyzed todetermine the total concentration of hydrocarbons by using a spectrofluorometer. The average ofhydrocarbon concentrations in the study area was ranged between (2.68 µg/g dry weight) at station(1) to (12.99 µg/g dry weight) at station (6). The results show that the spatial variations inhydrocarbon levels among stations, where the high concentrations in station (6) is due to receptionof large quantities of organic, chemical dissolved matters in water from domestic and industrialwastes such as agricultural effluents with other matters, while the low concentration at first stationis due to its being far away from pollution sources. This study itâs a first of its kind in the regionand could serves a baseline study for coming study in the futures.
