Can visible light impact litter decomposition under pollution of ZnO nanoparticles?

Light Pollution Changes the Toxicological Effects of Cadmium on Microbial Community Structure and Function Associated with Leaf Litter Decomposition

“…These results indicated that ALAN exposure can alter the fungal community structure and composition. This is consistent with the results of recent studies which showed that light radiation not only can alter the fungal community, but also inhibit litter decomposition associated with fungi [8][9][10]. However, our results differ from these studies [8,9] in that effects of different light conditions on the structure and diversity of fungal communities are significantly different.…”

“…This is consistent with the results of recent studies which showed that light radiation not only can alter the fungal community, but also inhibit litter decomposition associated with fungi [8][9][10]. However, our results differ from these studies [8,9] in that effects of different light conditions on the structure and diversity of fungal communities are significantly different. In Du's studies [8,9], the leaves were incubated under visible light (24 h/day) which would almost completely change the living environment of the fungi and the samples were not replicated when measuring fungal diversity.…”

“…Hence, the fungal community can be used as an indicator to evaluate the response to environmental stress [24]. Previous studies showed that light (UV radiation or ALAN) cannot only increase the degradation of complex aromatic compounds [25], but also alter microbial communities [5,[8][9][10]. Our results showed that ALAN exposure always decreased unique fungal OTUs and altered the abundance of the six most abundant genera (Figure 1a,b).…”

“…In freshwater ecosystems, there are more and more emerging pollutants, such as artificial light at night (ALAN, also known as light pollution) because of ongoing anthropogenic activities, especially near the streams there is a high concentration of people [4]. Many studies have indicated that ALAN can not only directly affect a very wide diversity of species including plants, animals, and microbes [4][5][6][7], but also indirectly affect other chemical pollutants by changing their states and associated environmental factors [5,[8][9][10]. Interactional effects between natural stressors (temperature, oxygen consumption, and heat) and toxicants (heavy metals and polycyclic aromatic hydrocarbons) have been studied [11,12].…”

“…Interactional effects between natural stressors (temperature, oxygen consumption, and heat) and toxicants (heavy metals and polycyclic aromatic hydrocarbons) have been studied [11,12]. Some recent studies also showed that excessive light (24 h/day) exposure can enhance the inhibitory 2 of 13 effect of nanoZnO on explaining light-induced dissolution of nanoZnO [8,9]. Our recent studies have shown that ALAN could not only alleviate the negative effects of silver nanoparticles (AgNP) or Pb on plant litter decomposition in streams but also affect the fungal community composition and function associated with litter decomposition [10,13].…”
