“…The bare and unvegetated calcine waste can produce dust with particulate-bound Hg during summer, which may be directly inhaled by the residents. In 2019, Hg in the atmosphere of the PQMI mine site was measured as high as 2,035-2,138 ng/m 3 at the area near mine waste calcine deposits, exposed natural soils, and rock outcrops, whereas it was measured at 8.44-61.63 ng/m 3 in the perimeter of the lake, which is close to the concentrations (64.9 ng/m 3 ) reported in 2002 (Maramba et al 2006;Samaniego et al 2020b).…”

“…Among the trace metals analyzed, Hg is considered the main contributor of non-carcinogenic risk of the area with HI of 3.1 x 10 1 and 1.3 x 10 1 for children and adults, respectively. These high HI for Hg were brought by the inhalation of soil vapor, which was demonstrated in the measurement of total Hg in the air in the PQMI area (Samaniego et al 2020b). However, there are uncertainties in this exposure pathway because it needs long-term monitoring in the area to gather reliable data on the volatility of Hg from soil and dynamics of particulatebound Hg in seasonal change, which was also observed in another study (Ordońez et al 2011).…”

Abandoned mines pose high risks to human health and the environment due to the disturbed and exposed metal-laden soils and sediments. In this study, soils and sediments in an abandoned mercury (Hg) mine in Puerto Princesa City, Philippines were analyzed to assess the potential adverse health effects of the exposure to trace metals associated with the mine wastes. A total of 63 soil and sediment samples were collected in the area and analyzed for Hg concentration using a direct Hg analyzer and inductively coupled plasma–mass spectrometry (ICP-MS) for other trace metals. Analysis results showed that aside from Hg, there are anomalous concentrations of Ni (nickel), Cr (chromium), and Mn (manganese) in the area brought by the value of the mineralogy of the ores that were mined. The measured trace metal concentrations, together with the United States (US) Environmental Protection Agency’s (EPA) exposure parameters and the US Department of Energy’s (DOE) toxicity values were used to calculate the dose contacted from different exposure pathways. The result of the health risk assessment showed that Hg was considered as the main contributor of non-carcinogenic risk in the area with a hazard index of > 1 for both children and adults. Inhalation of Hg vapor from the soils and sediments is found to be a significant addition to the health risks in the area. Other trace metals such as Co (cobalt), Fe (iron), Ni (nickel), and Tl (thallium) were calculated with a hazard index greater than 1, which poses a health risk to children due to the ingestion pathway. All carcinogenic trace metals assessed were below the guidance value, indicating no significant carcinogenic health risks for both adults and children in the area. This work serves as an initial step of the country in the assessment of the risks to human health and the environment brought by Hg contaminated areas, as stated in the Minamata Convention on Mercury.

“…Lastly, the receptor score was weighted on the frequency of the reported victims of physical harm from the source. The amalgamation of the physical hazard scores (PSc) is calculated as shown in (1) while total mine physical hazard score (TPSc) was taken as the average of all hazardous features present in each site (2), where n is the number of identified potential risk types, P is the physical hazard score per risk type, A is the amalgamation of source, pathway and receptor score and m is the number of identified features per site. The factor 1000 was used to reduce the magnitude of scores.…”

“…The dust generated from the mine wastes are also easily inhaled by the nearby communities. From the air monitoring study conducted on these regions, elevated values were recorded [2], contributing highly on the potential health problem criterion. Lastly, PQMI Tailings II was found adjacent to the local community landfill of Puerto Princesa City.…”

Abandoned mines remain a social, environmental, and health-risk problem for the Philippines. These abandoned sites are generally characterized by water-filled pit lakes surrounded with disturbed and exposed soils and sediments containing elevated values of heavy metals and other environmental contaminants. Previous studies with abandoned mines in the Philippines have initiated the use of integrated methods for the assessment of existing abandoned mine site conditions as a tool for decision-making. To further provide a numerical basis for rehabilitation prioritization, this paper aimed to utilize the modified Historic Mine Site Scoring System (HMS-SS) for physical and environmental hazard assessment of the abandoned mercury mine located in Barangay Sta. Lourdes, Puerto Princesa City, Philippines and to produce hazard classification maps based on the generated scores. Results identified the pit lake to be extremely hazardous physically, however, the liquid material (rainfall accumulation in the pit) yielded very low environmental hazard scores with only a few identified points that exceed the regulatory limit. Moreover, the two (2) identified mine tailings sites were found to be physically moderately hazardous but are categorized as extremely hazardous for the environmental aspect. The hazard scoring, coupled with the integrated environmental methods for characterization and development of hazard maps, is recommended as a scientific and quantitative basis for providing decisions in priority of actions to be taken with regards to abandoned mine sites.
