Air pollution has created a lot of problems in the developed and developing countries. To avoid or reduce these problems, constant monitoring of the air should be ensured. The conventional techniques is costly because it requires a lot of money and time consuming. Biomonitoring has been the alternative method. Moss, lichens and plants are biomonitors available to entrap air pollutants. The aim of this paper is to discuss one of the ways of monitoring air pollution -Moss bag technique. To do this, types, choice, preparation, handling of bags after preparation of moss were discussed. From the literatures consulted, it was discovered that there were differences in the techniques used by the researchers. In all, the use of mosses with emphasis on the employment of moss bag have proved to be a powerful tool in airborne particulate and toxic elements. To conclude, developing countries should focus more on this technique because it will reduce cost of air monitoring.

“…Mosses have found widespread use for monitoring purposes, but debate continues regarding how concentrations in moss can be interpreted and compared to bulk and/or wet deposition sampling methods [58,59]. For one, their accuracy as monitors will become reduced once exposure levels are high enough to impair metabolism [54].…”

To protect important resources under their bureau's purview, the United States National Park Service's (NPS) Arctic Network (ARCN) has developed a series of "vital signs" that are to be periodically monitored. One of these vital signs focuses on wet and dry deposition of atmospheric chemicals and further, the establishment of critical load (CL) values (thresholds for ecological effects based on cumulative depositional loadings) for nitrogen (N), sulfur, and metals. As part of the ARCN terrestrial monitoring programs, samples of the feather moss Hylocomium splendens are being collected and analyzed as a cost-effective means to monitor atmospheric pollutant deposition in this region. Ultimately, moss data combined with refined CL values might be used to help guide future regulation of atmospheric contaminant sources potentially impacting Arctic Alaska. But first, additional long-term studies are needed to determine patterns of contaminant deposition as measured by moss biomonitors and to quantify ecosystem responses at particular loadings/ ranges of contaminants within Arctic Alaska. Herein we briefly summarize 1) current regulatory guidance related to CL values 2) derivation of CL models for N and metals, 3) use of mosses as biomonitors of atmospheric deposition and loadings, 4) preliminary analysis of vulnerabilities and risks associated with CL estimates for N, 5) preliminary analysis of existing data for characterization of CL values for N for interior Alaska and 6) implications for managers and future research needs.

“…Both studies found that cadmium concentration in moss was positively and linearly correlated with cadmium concentration in rainwater (r = 0.91 and 0.87, respectively). Aboal et al (2010) reviewed the use of mosses as bio-indicators of atmospheric heavy metals, noting that moss concentrations of cadmium and lead are more consistently correlated with measurements of atmospheric deposition than concentrations of other metals. The correspondence of instrumentally measured heavy metal concentrations and those in moss suggest that moss could be used to complement existing networks of air-quality monitors.…”

L.; Amacher, Michael C.; and Monleon, Vicente J., "Using an epiphytic moss to identify previously unknown sources of atmospheric cadmium pollution" (2016 H I G H L I G H T S• Bio-indicators are a valid method for measuring atmospheric pollutants • We used moss to map atmospheric cadmium in Portland, Oregon • Using a spatial linear model, we identified two stained-glass manufacturers as the major sources of atmospheric cadmium in Portland • After both companies suspended cadmium use, atmospheric levels declined precipitously Urban networks of air-quality monitors are often too widely spaced to identify sources of air pollutants, especially if they do not disperse far from emission sources. The objectives of this study were to test the use of moss bioindicators to develop a fine-scale map of atmospherically-derived cadmium and to identify the sources of cadmium in a complex urban setting. We collected 346 samples of the moss Orthotrichum lyellii from deciduous trees in December, 2013 using a modified randomized grid-based sampling strategy across Portland, Oregon. We estimated a spatial linear model of moss cadmium levels and predicted cadmium on a 50 m grid across the city. Cadmium levels in moss were positively correlated with proximity to two stained-glass manufacturers, proximity to the Oregon-Washington border, and percent industrial land in a 500 m buffer, and negatively correlated with percent residential land in a 500 m buffer. The maps showed very high concentrations of cadmium around the two stainedglass manufacturers, neither of which were known to environmental regulators as cadmium emitters. In addition, in response to our findings, the Oregon Department of Environmental Quality placed an instrumental monitor 120 m from the larger stained-glass manufacturer in October, 2015.

Both stained-glass manufacturers voluntarily stopped using cadmium after the monitoring results were made public, and the monthly average cadmium levels precipitously dropped to 1.1 ng/m 3 for stained-glass manufacturer #1 and 0.67 ng/m 3 for stained-glass manufacturer #2.Published by Elsevier B.V.
