Acid rain induced leakage of Ca, Mg, Zn, Fe from plant photosynthetic organs – Testing for deciduous and dicotyledons

Simulated acid rains (AR), (pH 3.0, 3.5, 4.0, 4.5, 5.0, 5.5) were applied to green leaves of 13 deciduous trees (DT) and 10 species of dicotyledonous plants (DP). All were incubated at 23 °C within a growth chamber for 72 h. After the contact time, the leachates were analyzfor pH and next mineral el...
