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.

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. PubDate: 2022-02-17 DOI: 10.6092/issn.2281-4485/13435 Issue No:Vol. 47 (2022)

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.
