This can critically upset the quality of life in an urban city like Karachi. The purpose of present study was to examine the level of noise pollution due to transportation and its impacts on human health. For this purpose, two busiest business commercial roads of Karachi, M. A. Jinnah Road and Shahrah-e-Faisal were selected for measuring noise level at different timings of the day throughout the week during last week of April 2018. Collected data was statically analyzed by SPSS software. According to the research findings, the calculated average equivalent sound pressure levels were Leq 88.07dB at Old Radio Station Building, M. A. Jinnah Road and 86.09dB at Aisha Bhawani College, Shahrah-e-Faisal which is far above the acceptable limit of SEQS (Sindh Environmental Quality Standards). It is recommended that legislations and proper mitigation measures including noise barrier and absorbent installation to control this unseen pollution is needed to prevent noise impact on human health.</p> 2022-02-17T00:00:00+01:00 Copyright (c) 2022 Ambreen Aziz, Hashim Zuberi, Khalid Hassan, Urooj Haroon Heavy Metal Pollution Assesssment in Phosphate Mining and Processing Sites. Hahotoé and Kpémé in Togo 2021-08-18T22:08:41+02:00 Milohum Mikesokpo Dzagli Yawovi Mignanou Amouzouvi Kosi Sesime Kossivi Bienvenu Rodrigue Afoudji <p>The industrial activities related to phosphate mining and treatment constitute a threat to the population and its environment at Hahotoé and Kpémé (Togo) and released uncontrolled concentrations of toxic heavy metals that polluting soils, vegetation and water. The assessment of the pollution level would be useful for remediation, safeguard and prediction of risk to the environment and public. This study aims to assess the pollution level related to heavy metals in the soils, water and leaves at the phosphate mining (Hahotoé) and treatment (Kpémé) sites using spectroscopic techniques. Pollution indices such as contam- ination factor, degree of contamination, potential ecological risk index, pollution load index and heavy metal pollution index were used to achieve this goal. The average concentrations of Cd, Cr, Cu, Ni, Pb and Zn were investigated in the soils, leaves and water samples from the studied areas using the ZEEnit 700 with acetylene-air flame atomic spectrometer. High average concentrations of heavy metals were found in the samples exceeding the WHO limits. Heavy metal pollution index was used to assess the wa- ter quality with respect to heavy metals and very high value was found of 1168.84 at Kpémé and 733.58 at Hahotoé exceeding the critical value of 100. The results show unacceptable water quality for drinking on these sites. This study must help to design measures to reduce the pollutants released in the areas. The concerned issue poses a public health threat, so stakeholders would act in controlling the pollution level.</p> 2022-02-17T00:00:00+01:00 Copyright (c) 2022 Milohum Mikesokpo Dzagli, Yawovi Mignanou Amouzouvi, Kosi Sesime, Kossivi Bienvenu Rodrigue Afoudji COVID-19 Implicated Ban on Diwali Fireworks: A Case Study on the Air Quality of Rajasthan, India 2021-10-21T08:35:41+02:00 Devendra Singh Rathore Bhavya Singh Chirmaie Nagda Kapil Kumar Tanushree Kain Lalit Singh Jhala <p>Diwali is a five-day festival celebrated every year with lamp illumination and bursting of firecrackers in India. Considering the present situation of the COVID-19 pandemic, the Rajasthan government im- posed a ban on firecrackers during the five-day festivities in the year 2020 to tackle air pollution caused by the emission of harmful pollutant gases from their burning. This paper has assessed the concentration of PM10, PM2.5, CO and SO2 pollutants, which are released from fireworks in large amounts in the environment during the Diwali festival. Seven air quality monitoring stations viz. Ajmer, Alwar, Jaipur, Jodhpur, Kota, Pali and Udaipur in Rajasthan state were selected to examine the effect of a ban on the use of firecrackers during the Diwali festival. The analysis was done by comparing the mean concentrations of baseline data and Diwali day data of 2019 and 2020. The results depict that the firecracker ban helped in declining the concentrations of all the air pollutants (PM2.5, PM10, CO and SO2) taken into consid- eration, which significantly improved the ambient air quality of Rajasthan during the Diwali festival, and it is suggested that such regulations should be implemented from time to time to improve the quality of air and human health effectively.</p> 2022-02-17T00:00:00+01:00 Copyright (c) 2022 Devendra Singh Rathore, Bhavya Singh, Chirmaie Nagda, Kapil Kumar, Tanushree Kain, Lalit Singh Jhala Soil Quality Index of land impacted by anthropogenic activities in coastal Ghana 2022-01-06T05:21:37+01:00 Benjamin Ason David Kofi Essumnag Frederick Ato Armah Samuel Obiri <p>The excessive use of weedicide and fertilizer by farmers, indiscriminate waste disposal as well as unregulated and pervasive chemical use for mining and industry has huge impacts on the sustainability of soil resource.</p> <p>However, land use-specific characterization of soil has not been extensively studied. The soil quality of 4 different land use classes-cultivated soils, industry, decommissioned waste dump and forest reserve that depict different anthropogenic effect in urban and rural settings were assessed. Twelve composite samples were taken per site at a depth of 30cm with an auger, air dried and sieved with 2mm mesh and portions used for analysis. Soil mineral parameters analyzed include bulk density, reaction pH, organic carbon, total nitrogen, phosphorus, exchangeable cations: sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), and extractable trace elements: manganese (Mn), nickel (Ni), iron (Fe), cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb). The mean %SQIs for soil samples collected from cultivated soils, decommissioned dump, industrial and forest reserved sites are 54.9%, 57.6%, 60.6% and 61.4% respectively. Mean concentrations of Cd, Pb and Ni are 0.020 mg/kg, 1.301 mg/kg and 0.213 mg/kg, respectively. There were significant variations pairwise between cultivated soil and forest reserve soil and then cultivated and industrial soil (p&lt; 0.05). Assessing soil quality (SQ) through evaluation of changes in soil properties across different land use classes is an essential tool for proper management to promote sustainable use to sustain life.</p> 2022-05-11T00:00:00+02:00 Copyright (c) 2022 Benjamin Ason, David Kofi Essumnag, Frederick Ato Armah, Samuel Obiri Characterization of Mg-rich natural serpentine clay mineral and removal of reactive blue 19 from aqueous solutions 2021-12-31T00:31:04+01:00 Gökçe Didar Değermenci Nejdet Değermenci Nuray Emin Elif Aşıkuzun <p>The present study assessed the use of serpentine clay as adsorbent to remove the anionic dye agent of Reactive Blue 19 (RB19) from aqueous solutions. Firstly, serpentine clay minerals were characterized using different instrumental techniques like XRD, FTIR, SEM, TGA, XRF and BET analysis. As a result of characterization, the clay sample was determined to be serpentine group and it contained antigorite as dominant mineral type. Later, adsorption studies were performed and the effects of initial pH, adsorbent dosage, initial dye concentration and temperature on RB19 removal were investigated. The experimental results determined the highest adsorption capacity was obtained as 44.8 mg/g with initial RB19 concentration of 200 mg/L, temperature 25°C, adsorbent concentration 2 g/L and pH 7. According to isotherm results, the Langmuir isotherm model was more suitable to explain adsorption of RB19 on serpentine compared to the Freundlich isotherm model. Additionally, adsorption data indicate the pseudo-second-order kinetic model is a better fit rather than the pseudo-first-order kinetic model.</p> 2022-05-11T00:00:00+02:00 Copyright (c) 2022 Gökçe Didar Değermenci, Nejdet Değermenci, Nuray Emin, Elif Aşıkuzun
