The increase in ozone concentration by biogenic VOC is generally 5 ppbv or less, but could be more than 10 ppbv or even 30 ppbv in some local places. The impacts of biogenic NO_x are different or even contrary in different regions, depending on the relative availability of NO_x and VOC...
The observed effects from volcanic eruptions include stratospheric ozone loss, changes to precipitation (both amounts and patterns), and likely increased growth rates of forests, due to an increase in diffuse solar radiation (NAS, 2015), and provide insight into potential direct environmental impacts...
Further, ecological worries include contamination of air and water, environmental changes, depletion of ozone layer, a worldwide temperature alteration, decreased ground level water, alterations in biological system and biodiversity, arsenic tainting and others [128]. COVID-19 pandemic is a worldwide ...

The observed correlation of chlorophyll-a with stratospheric ozone (Figure 13B) suggests a direct and significant impact of UV-B on the phytoplankton community. More study of this phenomenon is needed because at this point only two depth ranges (0–30 m and 40–1...

200 - 800 m in the northern Utah valleys. CSL scientists Ale Franchin andAnn Middlebrookreported that aircraft observations during UWFPS showed high levels of NOx and particulate nitrate, and depletion of ozone throughout this shallow polluted boundary layer(Franchin, 2018)as shown on the right....

Ozone transforms pollutants directly or indirectly. But in any case, it works mainly by forming a less selective and stronger oxidant OH (Gerrity et al., 2011; Luo et al., 2014). In the presence of H2O2, ultraviolet and Fenton reagent, the production of OH will be contributed (Luo et ...
