Ectohydric moss, Thuidium tamariscellum, monitors atmospheric Lead (Pb) pollution in Baguio City, Philippines
Madison P. Munar*, Ralph Robie B. Oreiro and Roland M. Hipol
Abstract:
This is the first study in the Philippines which adopted the standard moss monitoring procedure to address Lead (Pb) contamination in the ambient air of Baguio City. Pb is considered as one of the seven criteria pollutants by United States Environmental Protection Agency. Analysis of exposed moss tissues was performed using Flame-Atomic Absorption Spectrophotometry by Baguio Water District. There is high metal loading observed on the tissues of Thuidium tamariscellum(Müll. Hal.) Bosch & Sande Lac.after exposure along and in between major road intersections in the city.There is no significant variation in Pb concentration in the exposed moss as revealed by One-Way Analysis of Variance. This study reports the presence of Pb in the ambient air of Baguio City and the lack of monitoring is harmful to people and environment. Nevertheless, this study offers cost-effective air monitoring method that can be adopted in cities as newer available technology.
