Abstract
This research group (forensic research via omics markers in environmental health vulnerable areas: FROM) aimed to develop biomarkers for exposure to environmental hazards and diseases, assess environmental diseases, and apply and verify these biomarkers in environmentally vulnerable areas. Environmentally vulnerable areas—including refineries, abandoned metal mines, coal-fired power plants, waste incinerators, cement factories, and areas with high exposure to particulate matter—along with control areas, were selected for epidemiological investigations. A total of 1,157 adults, who had resided in these areas for over 10 years, were recruited between June 2021 and September 2023. Personal characteristics of the study participants were gathered through a survey. Biological samples, specifically blood and urine, were collected during the field investigations, separated under refrigerated conditions, and then transported to the laboratory for biomarker analysis. Analyses of heavy metals, environmental hazards, and adducts were conducted on these blood and urine samples. Additionally, omics analyses of epigenomes, proteomes, and metabolomes were performed using the blood samples. The biomarkers identified in this study will be utilized to assess the risk of environmental disease occurrence and to evaluate the impact on the health of residents in environmentally vulnerable areas, following the validation of diagnostic accuracy for these diseases.

환경보건 취약지역 주민을 대상으로 실시한 현장 역학 조사에서 혈액과 소변 시료를 안정적으로 확보하였다. 현장에서 확보한 시료는 즉시 이송하여 오믹스 분석을 통해 환경유해인자별, 환경성질환별 특이적인 바이오마커를 개발한다.
Key Message
Blood and urine samples were stably obtained from on-site epidemiological investigations done on residents in environmental health vulnerable areas, and samples obtained from the sites were immediately transported to the omics laboratory after separation under biobank system. Through this analysis, we aimed to develop biomarkers specific to each environmental hazard and disease.

Abstract
OBJECTIVES
We aimed to determine the characteristics of the deceased victims of deaths caused by exposure to humidifier disinfectants, and present the distribution of the victims’ data submitted for damage application, demographic characteristics, imaging findings, characteristics of humidifier disinfectant exposure, and distribution of the causes of death.
METHODS An integrated database of victims was established using the medical records data of 1,413 victims submitted during the application for death damage caused by exposure to humidifier disinfectants, and the demographic characteristics, medical records, imaging findings, exposure characteristics, and cause of death were examined.
RESULTS The average numbers of data submissions of each applicant for death damage were 3.0 medical use records. A total of 608 (43.0%) victims had more than one finding of acute, subacute, or chronic interstitial lung diseases. The average daily and cumulative use times of the victims were 14.40 and 24,645.81 hours, respectively, indicating greater exposure in this group than in the survivors. The humidifier disinfectants’ components comprised polyhexamethylene guanidine (72.8%), chloromethylisothiazolinone/methylisothiazolinone (10.5%), other components (15.0%), and oligo-[2-(2-ethoxy)-ethoxyethyl] guanidine chloride (1.5%). The components’ distribution was 67.8% for single-component use, which was higher than that in the survivors (59.8%). The distribution of the causes of death were: respiratory diseases (54.4%), neoplasms (16.8%), and circulatory diseases (6.3%). Other interstitial lung diseases (65.5%) were the most common cause of death among those who died due to respiratory diseases.
CONCLUSIONS Careful discussions of appropriate remedies should be conducted based on a comprehensive understanding of the characteristics of the deceased victims, considering their specificities and limitations.

Summary
Korean summary
가습기 살균제 사망 피해 신청자 들 중 건강피해를 인정받지 못한 신청자들이 여전히 많이 남아있으며 (약 40%), 피해판정의 복잡성과 다양한 이슈들이 산적해 있어 사망 피해 신청자들의 적정 구제를 위해 종합적인 특성파악을 바탕으로 세심한 관점에서의 검토가 필요하다. 특히, 가습기 살균제 사망 피해 신청자의 특수성과 피해구제의 제한점을 고려하여야 하며, 기계적인 건강피해 판정을 지양하고 사망 피해 신청자 중심의 세밀한 특성 파악을 바탕으로 다양한 전문가집단이 참여하는 종합적인 논의를 통해 적정구제를 이루어 나가야 함을 제안한다.
Key Message
Careful discussions of appropriate remedies should be conducted based on a comprehensive understanding of the characteristics of the deceased victims, considering their specificities and limitations.
