Effects of Sulfur Dioxide on the Lichen Alga, with Special Reference to Chlorophyll

Ecophysiological responses of almond (Prunus dulcis) seedlings to cadmium stress

“…Greater sensitivity of chlorophyll b, as observed in this study, has been reported in other studies also (Mobin & Khan 2007;Gill et al 2012). Chl a is presumed to be degraded to phaeophytin, whereas chlorophyll b molecule loses its phytol group (Rao & Le Blanc 1966).…”

Teloschistes flavicans (sw.) Norman como indicador de poluição atmosférica em Paranaguá – PR

“…Um método para avaliação do stress liquênico devido a fatores ambientais é a avaliação da degradação da clorofila em feofitina em líquens transplantados (BOONPRAGOB, 2002;RONEN;GALUN, 1984), sendo a exposição ao SO 2 um dos principais fatores para esse efeito (RAO;LEBLANC, 1966). Tal método já foi utilizado para avaliar o impacto causado por atividades industriais (CARRERAS; PIGNATA, 2001;GARTY et al, 2000) e de despejo de resíduos sólidos (PAOLI et al, 2015).…”

“…Barkman (1958) give a list. In addition some later authors may be mentioned: Beschel (1958), Ried (1960), Lange and Bert eh (1965), Bertsch (1966), Rao and Le Blanc (1966).…”

“…Nylander himself declared that the absence of lichens in the outskirts of the Jardins du Luxembourg in Paris was due to air pollution originating in the surrounding buildings. Several scientists have as sociated themselves with this view in a more or less modified form, including Arnold (189 1-1901), Ser nander (1912,1926), Vaarna (1934), H�eg (1934), Vareschi (1936Vareschi ( , 1953, Sauberer (1951), Barbalic (1953), Beschel (1958), Skye (1958Skye ( , 1964Skye ( , 1965, Villwock (1959Villwock ( , 1962, Le Blanc (1961), Pivut (1962), Gilbert (1965), Pearson and Skye (1965), Domros (1966), Rao and Le Blanc (1966) and Laundon ( 1 967).…”
