“…To protect against such damage, plants produce antioxidant enzymes including SOD, POD, and CAT (Ju et al 2017a;Ren et al 2018a). The impact of acid rain on the activities of these enzymes has been found to be dependent upon acid rain pH (Liu et al 2018a;Ren et al 2018a). Herein, we determined that SOD, POD, and CAT activities were affected by soil type, SAR pH, and the interaction between these two variables (Fig.…”

“…As such, it is important to clarify the mechanisms whereby plant roots adapt to acid rain stress and altered mineral nutrient absorption, as there have been few studies of this topic to date. Acid rain can also indirectly affect plant roots by causing soil acidification and the release of basic ions, in addition to altering soil pH and other soil properties (Zhang et al 2016;Ju et al 2017a;Liu et al 2018a).…”

“…Given that each soil type exhibits unique properties, acidification can have variable impacts across soil types. Acid rain can alter soil pH and thereby impact the microbial activity therein, particularly in response to more significant acidification (Liu et al 2014(Liu et al , 2018a. Soil responses to acid rain will inevitably affect plant roots, governing their ability to thrive under acid rain conditions.…”

Acid rain remains a global environmental issue that can indirectly impact plant root growth and health by mediating soil acidification. The impact of acid rain on the roots of Jatropha curcas L., however, has not been thoroughly evaluated to date in soils with a range of buffering capacities. We, therefore, explored the ability of J. curcas roots to tolerate acid rain in a range of soil types by exposing samples to simulated acid rain (SAR) (pH2.5, pH3.5, pH4.5, pH5.6) and then examining the impact of such exposure on root morphology, relative growth rate (RGR root ), nutrient absorption, enzymatic activity, and microbial biomass. Yellow-brown soil (YBS) and purple soil (PS) were found to be better able to buffer SAR-mediated acidification, thereby providing superior benefits to J. curcas root growth as compared to red soil (RS) and yellow soil (YS) under these experimental conditions. SAR (pH 4.5) significantly enhanced Ca, K, and Mg absorption by J. curcas roots, thereby improving their growth characteristics, whereas SAR (pH 2.5) impaired K and Mg absorption and thus suppressed root growth. K and Mg absorption characteristics were regulated by changes in plasma membrane H + -ATPase activity under these different SAR treatment conditions. Morphological and growth (RGR root ) adaptations of J. curcas roots to SAR treatment were associated with superoxide dismutase activity levels therein. SAR (pH 4.5) was sufficient to bolster the rhizosphere microbial activity of J. curcas seedlings, and correlation analyses revealed that root growth was regulated by rhizosphere microbial biomass P content under SAR treatment conditions.

“…During the 1980s, the southern regions of China, including the southwestern forests, recorded high levels of AR [ 10 ], making China the country with the third-highest level of recorded AR [ 2 , 11 ] with recorded average pH values between 3.5 to 4.8 [ 12 , 13 ]. Acid rain deposition triggered a series of environmental issues in China, including the acidification of soil and water [ 14 , 15 ], plant damage, forest decline [ 2 ], and the loss of biodiversity [ 16 ].…”

Acid rain deposition (AR) has long-lasting implications for the community stability and biodiversity conservation in southwest China. Acer catalpifolium is a critically endangered species in the rain zone of Western China where AR occurs frequently. To understand the effects of AR on the morphology and physiology of A. catalpifolium, we conducted an acid stress simulation experiment for 1.5 years. The morphological, physiological, and photosynthetic responses of A. catalpifolium to the acidity, composition, and deposition pattern of acid stress was observed. The results showed that simulated acid stress can promote the growth of A. catalpifolium via the soil application mode. The growth improvement of A. catalpifolium under nitric-balanced acid rain via the soil application mode was greater than that of sulfuric-dominated acid rain via the soil application mode. On the contrary, the growth of A. catalpifolium was significantly inhibited by acid stress and the inhibition increased with the acidity of acid stress applied via leaf spraying. The inhibitory impacts of nitric-balanced acid rain via the leaf spraying of A. catalpifolium were greater than that of sulfur-dominant acid rain via leaf spraying. The observations presented in this work can be utilized for considering potential population restoration plans for A. catalpifolium, as well as the forests in southwest China.

“…But in this perspective, PCMs could become susceptible to the attacking effect of air contaminants, such as nitrogen oxides. During the past few years, nitrogen oxides pollution has turned into incredible terribleness owing to massive emissions of industrial waste gas and automobile exhaust . Specifically, the auxo‐action of nitrogen oxides for organics decomposition has been determined .…”

The effect of nitric acid on the thermal performance of stearic acid/kaolinite (SA/Kaol) composite phase change materials (PCMs) was studied. SA/Kaol was subjected to HNO3 manipulations at different acidity conditions. The results indicated that inferior thermal properties were detected at the acid‐treated composites with pH < 2. The latent heat value of SA/Kaol‐0.5 demonstrated an obvious reduction of about 30% compared with that of SA/Kaol, and its supercooling extent could reach as many as 11.2 °C while that of SA/Kaol was only 1.4 °C. Based on interfacial reaction analysis, the reduced crystallinity of SA should be attributed to the confinement effect originated from acid molecular clusters, while the supercooling behavior was caused by external ions. These ions could hinder SA molecules from adsorbing to the surface of crystal nucleus and thus delay the solidification process. As a result of segregation effect, the latent heat value of acid‐treated samples was deteriorated but the supercooling extent was relieved during thermal cycles. This work was the first that reported the effect of nitrogen oxides on PCMs. We believe that the results could play an enlightening role in the stability study of thermal property during PCMs practical applications.
