Is Active Moss Biomonitoring Comparable to Air Filter Standard Sampling?

Area of Science:

• Environmental Science
• Biomonitoring
• Air Quality Assessment

Background:

• Urban air quality and human health are significant concerns.
• Traditional dust samplers are costly; biological methods like moss biomonitoring are emerging.
• Current biomonitoring methods lack standardization and reliable comparison with instrumental data.

Purpose of the Study:

• To compare active biomonitoring using three moss species with instrumental dust collection for air pollution analysis.
• To assess the accumulation of specific analytes (Mn, Fe, Cu, Zn, Cd, Hg, Pb) in mosses exposed in an urban environment.
• To evaluate the impact of environmental change and pollutants on moss vitality and photochemical efficiency.

Main Methods:

• Active biomonitoring using the moss-bag technique with *Pleurozium schreberi*, *Sphagnum fallax*, and *Dicranum polysetum*.
• Exposure of moss samples in Opole, Poland, to measure accumulated analytes in total suspended particulates (TSP).
• Comparison of biomonitoring results with data from instrumental dust collectors.

Main Results:

• Moss species exhibited reduced lifetime and photochemical efficiency post-exposure, likely due to environmental changes and pollutants.
• Biomonitoring results showed incomplete consistency with the reference instrumental method.
• Analyte concentrations (Mn, Fe, Cu, Zn, Cd, Hg, Pb) were measured in collected TSP.

Conclusions:

• Active moss biomonitoring is a potential alternative to costly instrumental methods for air quality monitoring.
• The reliability of moss biomonitoring depends on specific monitoring goals, required sensitivity, measurement quality, and pollutant type.
• Further standardization and validation are needed for robust comparisons between biological and instrumental air quality data.
