Ultracytopathological characterization of leaves following short-term exposures of hydrogen chloride gas

“…Contaminants can cause leaf tissue destruction (necrosis) [12][13][14]. Under the influence of chlorine gas, the following acute morphological and physiological effects on species of coniferous plants were described and assessed: chlorosis, necrosis, decreased photosynthetic efficiency, damage to chloroplast membranes [14][15][16]. Trees growing near industrial enterprises suffer from a decrease in the average leaf area with a higher percentage of said area being damaged [17].…”

Primary leaves of Phaseolus vulgaris L. (pinto bean), 9 or 12 days from sowing, were exposed to aqueous acids, chloride salts, or hydrogen chloride gas. Leaves were examined for the presence and severity of resultant visible injury and sampled for light and scanning electron microscopy. Exposure to 0.06 n HCl, HNO3, H2SO4 or 14.5–19.0 mg m‐3 gaseous HCl for 20 min evoked similar foliar injury including glazing and necrosis of the laminas. This injury appeared to result initially from plasmolysis and collapse of the epidermis and subsequently of the underlying mesophyll. Cellular injury was accompanied by various cytoplasmic alterations. Microscopic symptoms observed in leaves exposed to gaseous HCl or aqueous acids included vesicles and particulates within the larger vacuoles. Similar symptoms were present in leaves exposed to polyethylene glycol 6000. Differential effects included formation of necrotic “pits” and preferential injury to paravascular tissues in leaves treated with aqueous acids and crystalline chloroplast inclusions in gaseous HCl‐treated and water‐stressed leaves. The visible and microscopic appearances of leaves exposed to aqueous acids or gaseous HCl were compared and related to injury stemming from acid precipitation and a possible mechanism of action for gaseous HCl phytotoxicity.
