“…The anthropogenic activities are known to be one of the primary drivers of pollution within various spheres of the environment ( Akimoto, 2003 ; Volkamer et al, 2006 ; Masood et al, 2016 ; Schlacher et al, 2016 ). Since the lockdown implemented due to COVID-19 in various countries has almost seized the industrial activities and vehicle movement, a decrease in air pollution across the globe has been reported ( Henriques, 2020 ; Stone, 2020 ).…”

The novel Coronavirus pandemic (COVID-19) hit the world severely in the first half of 2020 which forced several nations to impose severe restrictions on all sorts of activities involving human population. People were mainly advised to remain home quarantined to curb the virus spread. Industrial and vehicular movements were ceased as a result of lockdown, and therefore the rate of pollutants entering the ecosystem was also reduced in many places. Water and air pollution remained a major concern in the last few decades as these were gradually deteriorating in many spheres including the hydrosphere and atmosphere. As the nation-wide lockdown period in India completed more than two months, this study attempted to analyze the impact of lockdown on water and air quality to understand the short-term environmental changes. Using remote sensing data, this study demonstrated the improvements in ambient water quality in terms of decreased turbidity levels for a section of the Sabarmati River in the Ahmedabad region of India. The Suspended Particulate Matter (SPM) concentrations are evaluated to underline the turbidity levels in the study area before and during the lockdown period using the Landsat 8 OLI images. We noticed that the average SPM has significantly decreased by about 36.48% when compared with the pre-lockdown period; and a drop of 16.79% was observed from the previous year's average SPM. Overall, the average SPM concentration during the lockdown period (8.08 mg/l), was the lowest when compared with pre-lockdown average and long-term (2015–2019) April month average. The atmospheric pollution level (NO 2 , PM 2.5 , and PM 10 ) data obtained from the Central Pollution Control Board for Ahmedabad city also shows a significant improvement during the study period, implying a positive response of COVID-19 imposed lockdown on the environmental fronts.

“…This affects the chemical components of the river, because they are controlled by natural factors (geology, biological, and geomorphology) and anthropogenic activities (land use and industrial waste) (Syvitski et al, 2005;Shan et al, 2013). As the sediment is transported, the fluctuations in the mineralogical components affect the concentration of chemi-cal species (Masood et al, 2016). Whereas the investigation of sedimentary features can be used to reveal the input history of materials derived from the terrestrial environment (Calvert et al, 2001;Glasby et al, 2004;Naimo et al, 2005;Wei et al, 2006;).…”

The effect of topography, climate, soil, and geology on River Sadong sediments is related to its geochemistry. Eighteen surface sediments and five core samples were collected in replicates from six sampling sites along River Sadong, Sarawak, Malaysia. The main aim of this study is to describe the geomorphology and sedimentological characteristics of the river sediments. This was achieved by the study of the processes that form the sediments and influence their physical and chemical characteristics. The sediments were analyzed for their sedimentological characteristics. The results indicated that the studied area is enriched with organic matter, and there are no sedimentary structures in its vicinity.

“…Thus, TOC was not a determining factor in the distribution of ∑LABs in the sediments, and the intensity of a sewage input from different local sources was likely the key factor (Figure 4). Weak ∑LABs–TOC correlations determined for other areas of Peninsular Malaysia, such as the Selangor and Perak Rivers, were assessed using the R 2 values of 0.008 and 0.17, correspondingly, with similar indications (Magam et al 2015; Masood et al 2015).…”

21Linear alkylbenzenes (LABs) as sewerage indicators were investigated in the sediments of the 22 West and South Peninsular Malaysia. Surface sediment samples were analyzed using gas 23 chromatography-mass spectrometry. Results showed that LAB concentration in the samples 24 of Port Dickson and the Kim Kim River varied from 111.6 to 255.8 and from 88.2 to 119.0 25 ng•g −1 dry weight, respectively. The ratios of internal isomer, in which the benzene ring was 26 close to the center of the linear alkyl chain, to external isomer, in which the benzene ring was 27 near the end of the linear alkyl chain (I/E ratios), of LABs in Port Dickson coast sediments 28 ranged from 2.6 to 4.1. By contrast, the ratios for sediment from the Kim Kim River varied 29 from 1.7 to 1.9. I/E, long-chained LABs over short-chained LABs (L/S), and C 13 /C 12 ratios 30 indicated that the aquatic environment received primary and secondary sewage effluents. These 31 findings emphasized the necessity of continued water treatment system development in 32 Malaysia.33
