“…Because the purpose of this pilot case study is to determine the feasibility of comprehensively integrating personal exposome and internal multi-omics to investigate the phenotypic variations, the validation of those testable hypotheses should be performed after this study. In addition, we focused on the airborne exposome and did not measure other exposures, such as dermal and ingestion exposures, inorganic chemical components ( Gao et al 2019a ; Xu et al 2019 , 2020 ; da Silva et al 2020 ), psychosocial stressors, and personal lifestyle, which may affect the clinical measurements as well ( Fig. 6 A).…”

Conventional environmental health studies have primarily focused on limited environmental stressors at the population level, which lacks the power to dissect the complexity and heterogeneity of individualized environmental exposures. Here, as a pilot case study, we integrated deep-profiled longitudinal personal exposome and internal multi-omics to systematically investigate how the exposome shapes a single individual's phenome. We annotated thousands of chemical and biological components in the personal exposome cloud and found they were significantly correlated with thousands of internal biomolecules, which was further cross-validated using corresponding clinical data. Our results showed that agrochemicals and fungi predominated in the highly diverse and dynamic personal exposome, and the biomolecules and pathways related to the individual's immune system, kidney, and liver were highly associated with the personal external exposome. Overall, this data-driven longitudinal monitoring study shows the potential dynamic interactions between the personal exposome and internal multi-omics, as well as the impact of the exposome on precision health by producing abundant testable hypotheses.

“…It should also be noted that the lowest bioavailability of P in soil was recorded in sample 1.2 (BAC + Cr). This may explain why Cr bioavailability was recorded in sample 1.2 (BAC + Cr) at the end of the test, since Cr is an analog of P and a lower bioavailability of P in the soil may indicate that it is in the biochar competing for binding sites. , However, to further elaborate on the above, a daily analysis of P bioavailability monitoring was performed for each soil type (Cr, Cd, or Pb) regardless of the type of treatment (Figure c). No significant effect of time on P bioavailability was found for the three soil types.…”

Soil contamination with heavy metals (HM) poses significant challenges to food security and public health, requiring the exploration of effective remediation strategies. This study aims to evaluate the remediation process of soils contaminated with Cd, Cr, and Pb using Lolium perenne assisted by four types of biochar: (i) activated coffee husk biochar (BAC), (ii) nonactivated biochar coffee husk (BSAC), (iii) activated sugar cane leaf biochar (BAA), and (iv) nonactivated biochar sugar cane leaf (BSAA). Biochar, loaded with phosphorus (P), was applied to soils contaminated with Cd, Cr, and Pb. L. perenne seedlings, averaging 2 cm in height, were planted. The bioavailability of P and heavy metals (HM) was monitored every 15 days until day 45, when the seedlings reached an average height of 25 cm. At day 45, plant harvesting was conducted and stems and roots were separated to determine metal concentrations in both plant parts and the soil. The study shows that the combined application of biochar and L. perenne positively influences the physicochemical properties of the soil, resulting in an elevation of pH and electrical conductivity (EC). The utilization of biochar contributes to an 11.6% enhancement in the retention of HM in plant organs. The achieved bioavailability of heavy metals in the soil was maintained at levels of less than 1 mg/kg. Notably, Pb exhibited a higher metal retention in plants, whereas Cd concentrations were comparatively lower. These findings indicate an increase in metal immobilization efficiencies when phytoremediation is assisted with P-loaded biochar. This comprehensive assessment highlights the potential of biochar-assisted phytoremediation as a promising approach for mitigating heavy metal contamination in soils.

“…Undoubtedly, due to the limitation of the single participant and annotation power in this study, future research should monitor the precision environmental health of 15 more individuals and increase the annotation confidence of the chemical and biological components in the exposome. In addition, we focused on the airborne exposome and did not measure other exposures, such as dermal and ingestion exposures, inorganic chemical components [50][51][52][53], psychosocial stressors, as well as personal lifestyle, which may affect the clinical measurements as well (Figure 6a). Nonetheless, this study demonstrates the power of using a holistic approach of monitoring the exposome on personal environmental health using inter-omics analyses, and serves as a useful model to scale to the other individuals and locations.…”
