Several articles have appeared in the literature regarding the impact of stratospheric ozone depletion on the prevalence of skin cancer due to increasing ultraviolet radiation. While it has been shown that UVB radiation is related to carcinogenesis of both melanoma and non-melanoma skin cancer, it has not definitively been shown that stratospheric ozone depletion is translating into increased penetrating ultraviolet radiation. Estimates of increasing skin cancer in the future are dependent on calculations of UVB increases drawn from data on ozone depletion. The present article describes the history of stratospheric ozone depletion, how it may affect UVB penetration and skin cancer rates, and what is currently being done to prevent man's further detrimental effects on our atmosphere.

Hydroxyl (OH) is the atmosphere's main oxidant removing most pollutants including methane. Its short lifetime prevents large-scale direct observational quantification. Abundances inferred using anthropogenic trace gas measurements and models yield conflicting trend estimates.

Alpine wet meadows are known as NO sinks due to nitrogen (N) limitation. However, phosphate addition and N deposition can modulate this limitation, and little is known about their combinative effects on NO emission from the Qinghai-Tibet Plateau in wet meadows. This study used natural wet meadow as the control treatment (CK) and conducted experiments with N (CONH addition, N15), P (NaHPO addition, P15), and their combinations (CONH and NaHPO addition, N15P15) to investigate how N and P supplementation affected soil NO emissions in wet meadow of QTP.

This paper investigates the evolution of changes in surface ultraviolet (UV) radiation globally, emphasizing the significant impacts of key factors influencing its variability, i.e., total column ozone, aerosols, clouds, and surface reflectivity.

Bromine is a significant environmental threat due to its corrosive nature and contribution to ozone layer depletion. It often coexists with iodine and forms interhalogen complexes (IBr), which require an effective and selective bromine adsorption strategy. Leveraging the electrophilic nature of bromine, we designed an electron-rich thiophene-based porous organic polymer (POF-2).

Photodissociation of the CH2Cl radical is investigated by using high-level multireference configuration interaction ab initio methods, including the spin-orbit coupling. All possible fragmentation pathways, namely, CH2Cl + hν → CH2 + Cl, HCCl + H, and CCl + H2, have been analyzed. The potential-energy curves of the ground and several excited electronic states along the corresponding dissociating bond distance of each pathway have been calculated.
