Method: "Anion Concentrations We analyzed our samples for seven anions using the Ion Chromatograph (For a sample readout from the Ion Chromatograph, see Figure 3 in Appendix). Of the seven nations we analyzed for, fluoride and bromide were not present in any of the samples (see Figure 4)." page 8
This means it was not looked for other substances except those declared for. The reason of this way of research is the research interest. If the focus of the research interest is looking for causes of forest dying it will look into the biology of the forests and how it could be effected by common human influence. There is no thought on a possible conspiracy or secret circumstances for whatever reason. At least, this will be the case of some college students probably - and at that time. And of course, if you don't know what to look for, the research gets even more expensive until you know what is all in the air. It is a little bit like with the electromagnetic frequency spectrum which is also huge.
Presentation "Regnet es wirklich Säure?" within the study course to receive a degree as a chemistry teacher by Caroline Roos Frankfurter Str. 20 35037 Marburg Germany December 1998 ("Regnet es wirklich Säure?" = "Does it really rain acid?")
Experiment with acid rain to prove the mobilisation of Aluminum-ions: "VERSUCH 5 Mobilisierung von Metall-Ionen durch Sauren Regen [Acid rain] Geräte und Chemikalien: 100 mL Becherglas, Schütteltrichter (100 mL). Destilliertes Wasser, Glaswolle, 2%ige Schwefelsäure, Eisessig, Morin-Lösung.
Durchführung: Den Boden des Schütteltrichters mit Glaswolle auslegen. Anschließend mit 10 mL luftgetrockneter Erde füllen. Auf die Erdprobe gibt man 100 mL Wasser, das durchgelaufene Wasser wird im Becherglas aufgefangen. Nun gibt man 100 mL der angesetzten Schwefelsäure hinzu, und fängt die durchgelaufene Lösung ebenfalls im Becherglas auf.

Obviously, the learning success of the college class above was not that acidic rain (from the sulfates) looses the aluminum from the molecular compounds in the soil but to learn how to measure acidic rain in general. Investigating the plant-sickening consequences of the acidity of the rain would have focussed on the aluminum itself.
