“…The front and rear gas valves were shut off successively to provide air tight conditions under ordinary pressure, and irradiation was put on after reaching the temperature and RH designed for the experiment. The irradiation intensity of the reactor was set at 100 mW·cm –2 , which could well simulate the average outdoor solar radiation. , The temperature (298 ± 0.5 K) was controlled by a low-temperature circulation chiller. The irradiation time was set to 0–720 min, and the dark control group was treated in the same way, except there was no irradiation.…”

A large-scale survey was conducted by measuring five organophosphite antioxidants (OPAs) and three novel organophosphate esters (NOPEs) in 139 dust samples across China. The median summed concentrations of OPAs and NOPEs in outdoor dust were 33.8 ng/g (range: 0.12−53,400 ng/g) and 7990 ng/g (2390−27,600 ng/g), respectively. The dust concentrations of OPAs associated with the increasing economic development and population density from western to eastern China, whereas the NOPE concentration in Northeast China (median, 11,900 ng/g; range, 4360−16,400 ng/g) was the highest. Geographically, the distribution of NOPEs was significantly associated with annual sunshine duration and precipitation at each sampling site. Results of laboratory experiments further revealed that the simulated sunlight irradiation promoted the heterogeneous phototransformation of OPAs in dust, and this process was accelerated with the existence of reactive oxygen species and enhanced relative humidity. Importantly, during this phototransformation, the hydroxylated, hydrolyzed, dealkylated, and methylated products, e.g., bis(2,4-di-tert-butylphenyl) methyl phosphate, were identified by nontargeted analysis, part of which were estimated to be more toxic than their parent compounds. The heterogeneous phototransformation pathway of OPAs was suggested accordingly. For the first time, the large-scale distribution of OPAs and NOPEs and the phototransformation of these "new chemicals" in dust were revealed.

“…A large fraction of the studies dealing with solar radiation published during recent years have considered models of solar radiation (e.g., Quej et al ., 2016; Yao et al ., 2017; Jamil and Siddiqui, 2018; Antonopoulos et al ., 2019; Cao et al ., 2020), often focusing on the application of solar radiation calculations and forecasting with regard to photovoltaic (PV) power plants (e.g., Ghofrani et al ., 2016; Bouzgou and Gueymard, 2017; Eseye et al ., 2018; Srivastava et al ., 2019; Das, 2020). The global, direct, and diffuse radiation are commonly measured in the field (Marques Filho et al ., 2016; Gairaa et al ., 2017; Othman et al ., 2018; Chamorro et al ., 2020; Mohammad et al ., 2020).…”

This study deals with the impact of season, cloud cover, and air pollution on spectral regions of incident solar radiation (UVB, UVA, photosynthetically active radiation (PAR) = Blue + Green + Red, 660, 730 nm) and their ratios (Blue/Red, Blue/PAR, Green/PAR, Red/PAR, 660/730 nm, UVB/UVA, UVB/PAR, and UVA/PAR) measured at three measuring stations at two locations in the City of Ostrava, Czech Republic. The mentioned spectral regions are crucial for plants because they influence photosynthesis and photomorphogenesis. However, there is still a lack of published information about the radiation regime in the plants' environment. The measured data underwent a quality check and were divided into 40 groups corresponding to different combinations of season, cloud cover, and air pollution level. Standard statistical characteristics of spectral regions and their ratios were calculated for each combination. Generalized linear models were used to evaluate the effect of air pollutants on spectral regions of incident solar radiation. Average irradiance values in the spectral regions generally decreased with increasing air pollution on both cloudy and sunny days. A mostly decreasing trend of average values of ratios with increasing air pollution is found mainly on sunny days and, for some cases, even on cloudy days. Each ratio shows a specific patterns depending on the season and cloud cover. The generalized linear models confirm previously published results and underline that air pollution affects various spectral regions of incident solar radiation differently.
