Title Spatial Trend Of Light Pollution In Obio/Akpor Lga, Rivers State, Nigeria Type Journal Article
Year 2020 Publication International Journal of Novel Research in Civil Structural and Earth Sciences Abbreviated Journal
Volume 7 Issue 2 Pages
Keywords Lighting; Perception
Abstract The study examines the spatial trend of light pollution across the study area. The Global Positioning System (GPS) was used to acquire the coordinates of each respondent resident, where structured questionnaire were administered in the study area and then imported to the ArcGIS 9.3 software environment to analyse the spatial trend in light pollution using the Inverse Distance Weighted (IDW) method of interpolation. Findings, reveals that the perception of pollution by light stray is obviously noticed by the respondents with particular emphasis on light stray from traffic light, neighbor security lights which to a large extend alters their level of comfort and distort their level of outdoor relaxation. Thus, the study recommends, among others, that: shielded light bulbs or properly designed light fittings should be installed to avoid light rays spreading beyond the needed boundaries. And measure should be taken to ensure car drivers use properly fixed headlamps that are not damaged and also, awareness should be passed on adequate use of headlamps by road users (vehicle drivers) on streets when compared with use on highways and minor roads.

Title Avoiding room light during night may stimulate immunity in COVID-19 patients by promoting melatonin production Type Journal Article
Year 2020 Publication Melatonin Research Abbreviated Journal
Volume 3 Issue 4 Pages 476-481
Keywords Human Health; Commentary
Abstract COVID-19 is one of the greatest health issues facing humankind for many decades; it emerged in Wuhan, China, late in December 2019, and rapidly spread over the world within the short period. This report emphasizes the potential hazards of exposure to room light at night which affects the immunity of COVID-19 patients by suppressing their melatonin, which is only released from the pineal gland at night. Exposure to light at night is especially common in the hospital setting. This may make the symptom worse for the hospitalized patients and the light at night should not be ignored. Thus, I suggest that COVID-19 patients should avoid light at night either by wearing eye masks or darkening the room to enhance pineal melatonin synthesis and increase their serum melatonin levels.

Title Spatiotemporal Patterns of COVID-19 Impact on Human Activities and Environment in Mainland China Using Nighttime Light and Air Quality Data Type Journal Article
Year 2020 Publication Remote Sensing Abbreviated Journal Remote Sensing
Volume 12 Issue 10 Pages 1576
Keywords Remote Sensing
Abstract The sudden outbreak of the COVID-19 pandemic has brought drastic changes to people’s daily lives, work, and the surrounding environment. Investigations into these changes are very important for decision makers to implement policies on economic loss assessments and stimulation packages, city reopening, resilience of the environment, and arrangement of medical resources. In order to analyze the impact of COVID-19 on people’s lives, activities, and the natural environment, this paper investigates the spatial and temporal characteristics of Nighttime Light (NTL) radiance and Air Quality Index (AQI) before and during the pandemic in mainland China. The monthly mean NTL radiance, and daily and monthly mean AQI are calculated over mainland China and compared before and during the pandemic. Our results show that the monthly average NTL brightness is much lower during the quarantine period than before. This study categorizes NTL into three classes: residential area, transportation, and public facilities and commercial centers, with NTL radiance ranges of 5–20, 20–40 and greater than 40 (nW· cm−2 · sr−1 ), respectively. We found that the Number of Pixels (NOP) with NTL detection increased in the residential area and decreased in the commercial centers for most of the provinces after the shutdown, while transportation and public facilities generally stayed the same. More specifically, we examined these factors in Wuhan, where the first confirmed cases were reported, and where the earliest quarantine measures were taken. Observations and analysis of pixels associated with commercial centers were observed to have lower NTL radiance values, indicating a dimming behavior, while residential area pixels recorded increased levels of brightness after the beginning of the lockdown. The study also discovered a significant decreasing trend in the daily average AQI for mainland China from January to March 2020, with cleaner air in most provinces during February and March, compared to January 2020. In conclusion, the outbreak and spread of COVID-19 has had a crucial impact on people’s daily lives and activity ranges through the increased implementation of lockdown and quarantine policies. On the other hand, the air quality of mainland China has improved with the reduction in non-essential industries and motor vehicle usage. This evidence demonstrates that the Chinese government has executed very stringent quarantine policies to deal with the pandemic. The decisive response to control the spread of COVID-19 provides a reference for other parts of the world.

Title The Dimming of Lights in India during the COVID-19 Pandemic Type Journal Article
Year 2020 Publication Remote Sensing Abbreviated Journal Remote Sensing
Volume 12 Issue 20 Pages 3289
Keywords Remote Sensing; COVID
Abstract The monthly Suomi National Polar-orbiting (NPP) Visible Infrared Imaging Radiometer Suite (VIIRS) Day–Night Band (DNB) composite reveals the dimming of lights as an effect of the lockdown enforced by the government of India in response to the COVID-19 pandemic. The changes in lighting are examined by creating difference maps of a pre-pandemic pair and comparing it with two pandemic pairs. The visual raster difference maps are substantiated with quantitative analysis showing the proportion of population affected by the changes in the lighting brightness levels. In the pre-pandemic images of February and March 2019, 60% of the population lived in administrative units that became brighter in March 2019. However, in the first pandemic pair, 87% of the population lived in administrative units that became dimmer in March 2020 after the lockdown in comparison to February 2020. The nightly DNB profile at the airport in Delhi illustrate how the dimming of lights coincide with the date of the onset of the lockdown (in March 2020). The study shows the usefulness of the DNB nightly and monthly composites in examining economic impacts of the pandemic as countries throughout the world go through economic declines and move towards recovery.
