“…This has been previously explained as the decrease in chlorophyll concentration may reflect their degradation, because acid rain generates an imbalance in H + ions in leaf cells [61]. In addition, the increase in H + ions could displace Mg 2+ from the chlorophyll molecule, turning into pheophytin [62]. Finally, the decrease in chlorophyll a and b depends upon the pH of the simulated acid rain and the exposure time [63].…”

Megapolis such as Mexico City, have atmospheric pollutants that interact with the humidity and solar radiation. The topography of this city promotes air stagnation, generating atmospheric pollutants and episodes of acid rain, a phenomenon well recorded since the end of the 1980s. However, little we know about how urban trees respond to acid rain in the city. Here we present how simulated acid rain causes anatomical and changes in photosynthetic pigments in two of the most abundant urban trees in Mexico City: Liquidambar styraciflua L. and Fraxinus uhdei (Wenz.) Lingelsh. We first described the leaf anatomy of both species. Then, we used one-year-old trees sprayed with sulfuric acid solutions at pH 2.5 and 3.8, and evaluated visible leaf damage, anatomical alterations, and chlorophyll contents. In both species, the pH 2.5 caused cuticle alterations and areas of total tissue destruction. L. styraciflua showed greater sensitivity, but we discuss some of the tolerance mechanisms. Finally, acid rain also reduced the chlorophyll contents. These results contribute toward a catalogue of urban tree species to describe pollution-induced damages, and the identification of tolerant species useful for short- and mid-term detection of environmental crisis, in cities with similar environmental conditions and urban tree composition.

“…Highly acidic deposition may cause many problems, ranging from killing freshwater fish and damage to crops, to erosion of buildings and monuments (Manahan, 2001). Additionally, acid deposition alters soil chemistry, nutrient availability and plant growth; thus, its effects on terrestrial ecosystems may be chronic and accumulative (Shan, 1998), leading to trees and shrubs being weakened and becoming more vulnerable to insects, diseases and fungal infestations (Eamus and Fowler, 1990;USEPA, 2010).…”

The Eco-physiological assessments of variable parameters known to be essential for proper plant growth and health were determined in cucumber plants exposed to short term treatments in 42 days using two broad classification types; Photo Fenton solution generating OH radicals and simulated acids. Solutions containing different classification of scavengers of OH radicals and mannitol were employed as Controls. Results indicated that the acid rain and photo Fenton solution both decreased the photosynthetic rate (Amax), stomatal conductance (gs), photochemical efficiency of PSII in the dark (Fv/Fm), SPAD chlorophyll and they imparted severe foliar injuries on cucumber leaves. The acids treatments have the highest negative impact followed by the photo Fenton Solution. The mechanisms of phytotoxicity of the two solutions may be through OH radical and other Reactive Oxygen Species (ROS) generation. The addition of mannitol, catechin hydrate and tea solutions to the acids and photo Fenton solution mixtures all mitigated the negative effects of the duo on the cucumber plants. Mannitol at dosage applied in the present study can be adjudged to be the best in the amelioration of the negative effects of the fumigants. Future plant protection from deleterious impacts of atmospheric and hydrospheric pollutants can employ mannitol as scavengers of ROS.
