“…First, most monitors measure PM 2.5 only, including the local site ‘DW,’ which may explain why arsenic wasn’t detected there (Section 4.2). In contrast, moss tissues accumulate heavy metals within the broader PM 10 size range (Adamo et al 2008, Mariet et al 2011, Massimi et al 2019, Tretiach et al 2011). Second, like the hotspots depicted in our maps, deposition of coarse particles is acute (i.e.…”

Heavy metals concentrations often vary at small spatial scales not captured by air monitoring networks, with implications for environmental justice in industrial-adjacent communities. Pollutants measured in moss tissues are commonly used as a screening tool to guide use of more expensive resources, like air monitors. Such studies, however, rarely address environmental justice issues or involve the residents and other decision-makers expected to utilize results. Here, we piloted a community science approach, engaging over 55 people from nine institutions, to map heavy metals using moss in two industrial-adjacent neighborhoods. This area, long known for disproportionately poor air quality, health outcomes, and racial inequities, has only one monitor for heavy metals. Thus, an initial understanding of spatial patterns is critical for gauging whether, where, and how to invest further resources towards investigating heavy metals. Local youth led sampling of the moss Orthotrichum lyellii from trees across a 250×250-m sampling grid (n = 79) and generated data comparable to expert-collected samples (n = 19). We mapped 21 chemical elements measured in moss, including 6 toxic ‘priority’ metals: arsenic, cadmium, chromium, cobalt, lead, and nickel. Compared to other urban O. lyellii studies, local moss had substantially higher priority metals, especially arsenic and chromium, encouraging community members to investigate further. Potential hotspots of priority metals varied somewhat but tended to peak near the central industrial core where many possible emissions sources, including legacy contamination, converge. Informed by these findings, community members successfully advocated regulators for a second study phase – a community-directed air monitoring campaign to evaluate residents’ exposure to heavy metals – as is needed to connect moss results back to the partnership’s core goal of understanding drivers of health disparities. This follow-up campaign will measure metals in the PM10 fraction owing to clues in the current study that airborne soil and dust may be locally important carriers of priority metals. Future work will address how our approach combining bioindicators and community science ultimately affects success addressing longstanding environmental justice concerns. For now, we illustrate the potential to co-create new knowledge, to help catalyze and strategize next steps, in a complex air quality investigation.

“…First, most monitors measure PM 2.5 only, including the local site “DW,” which may explain why arsenic was not detected there. By contrast, moss tissues accumulate heavy metals within the broader PM 10 size range (Adamo et al, 2008; Mariet et al, 2011; Massimi et al, 2019; Tretiach et al, 2011). Second, like the hotspots depicted in our maps (e.g., Figure 5), deposition of coarse particles is acute (i.e., concentrations vary widely across small areas) compared to the more gradual, regional‐scale patterns of PM 2.5 (Massimi et al, 2019; Pakbin et al, 2010; Zhang et al, 2014).…”

“…Bio monitoring is one of the simplest and cheapest method for detecting heavy metal concentration in the ambient air 11,12 . Plant bio monitoring is the better choice for determining the air quality compared to other conventional method because of its cheapness and easy to carry out the work.…”

Kanchipuram, one of the holiest cities is highly polluted with heavy metals due to industrialization and urbanization. It is most important to know the role of plants in the cleansing process of heavy metals in this temple city. In this study, the heavy metals (Fe 2+ , Pb 2+ , Cu 2+ , Zn 2+ , Al 2+ , Cd 2+ , As 2+ , Cr 3+ , Mn 2+ ) from the dust deposited on the leaves of the trees were analyzed. The tree species were collected from different zones of the Kanchipuram town such as residential area, traffic area, Institutional area, hospital area and industrial area. Heavy metals concentrations were analyzed by inductively coupled plasma mass spectrometry. Most of the heavy metals were found below their detectable limits (Pb 2+ , Cd 2+ , Cu 2+ , Cr 3+ , and As 2+ ). Some of the heavy metals were in highly increased values (Fe 2+ , Al 2+ ) almost in selected species. In few locations the content of As 2+ and Mn 2+ in lower levels were deposited on some species. The results obtained from the analysis were compared statistically and correlated by using Pearson's co-efficient. The results obtained from the analysis shown that the heavy metals were emitted from various combustion processes and other anthropogenic activities. The tree species selected can be used in bio monitoring as bio indicators of increased Fe 2+ , Al 2+ in the ambient air.
