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.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47196219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70598397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45698833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49374307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
