The impact of indoor air quality on human health is gaining importance as people spend 90% their time indoors. It has been established that occupancy a significant contributor to Volatile Organic Compound (VOC) concentrations and concern regarding occupant health, yet VOC emissions remain largely uncharacterised. In the current study, we review recent research examines contributions humans profile in occupied spaces, with focus study characteristics. This investigation identified hierarchy factors contributing inter-study variations biogenic (HVOC) levels measured We found variation reported HVOC are related sampling techniques used, test conditions, sample analysis. Contrasting findings issues such effect nutrition smoking discussed. Conclusions were reached about advancements nature results need use larger datasets, recommendations global guidelines future testing have made. advocate for unified approach studies, promoting more coordinated data collection reporting fostering development impactful applications.

In late December 2019, a novel coronavirus, COVID −19 originated in Wuhan city of China, and significant improvement not only the air quality but also water quality. Therefore, current study demonstrates changes parameters Ghaggar river, Punjab, India. The variations river have been examined during pre-, during, post-pandemic periods. maximum temperature for all monitoring stations was between 28 to 37°C pandemic period, whereas dissolved oxygen value varied from 3 7 mg/L. pH obtained reported be 7.7 8.0, except chhatbir station (7.6). biochemical demand found 18–53 Strong positive correlations were observed total coliform fecal pre (0.76) (0.89) Similar recorded BOD conductivity (0.75) (0.58)

In December 2019, a novel coronavirus disease (COVID-19) outbreak occurred due to human respiratory virus that originated in the city of Wuhan, China. During COVID-19 lockdown, there was significant improvement air quality across world. We analyzed data for BTEX over three years (January 2019 2021) with pairwise comparison and trend analysis pre-, during, post-pandemic periods. This study demonstrates substantial changes concentration VOCs urban area (Punjab) lockdown effects. The results indicate reduction mean TVOCs all monitoring stations found be 8.89 ± 1.80, 5.59 1.71, 5.57 1.43 μg/m3 before, post-pandemic, respectively. level declined by −43% during period compared previous years. A higher T/B ratio Patiala (2.97 μg/m3) before pandemic, which may vehicle emission sources. LCR values benzene were children than males females, indicated possible risk. exceeded prescribed value CPCB children.

This study examines the levels of benzene and potential health impact during three years continuous monitoring (2019–2021), including COVID-lockdown period from 2020 in a city that is an important Romanian center for petroleum refining associated product manufacturing. The dataset contains benzene, toluene, NOx, PM10 concentrations, meteorological factors monitored by six automatic stations national network which four are two outside. Special attention was given to dynamics establish patterns related leukemia. An assessment exposure performed using EPA’s ExpoFIRST v. 2.0 computing inhalation Average Daily Dose (ADD) Lifetime (LADD). estimated based on several indicators such as lifetime cancer risk (LCR), Hazard Quotient (HQ), Disability-Adjusted Life Years (DALY), Environmental burden disease (EBD). Overall, annual average all almost similar between i.e., 3.46 2019, 3.41 2020, 3.63 µg/m3 2021, respectively. lockdown 2.67 µg/m3, lower than multiannual 2019–2021 period, 3.5 µg/m3. Significant correlations were present other pollutants NOx (r = 0.57), fraction 0.70), toluene 0.69), temperature −0.46), humidity 0.28), wind speed −0.34). Regarding ADD, scenarios, most affected age categories small children, despite outdoor time.
