In addition, previous research found that soil organic carbon (SOC) plays an essential role in controlling Hg distribution and speciation. However, there is minimal information on the Hg storage distribution and their relationships with SOC in the WLFZ in TGR. This study investigated Hg distribution, storage, and their relationships with SOC in the surface soils in WLFZ. The results showed that the total Hg (THg) content in the surface soils ranged from 18.40 to 218.50 ng g\u22121, with an average value of 78.17 \u00b1 41.92 ng g\u22121. About 89% of samples had THg content above the background value in Chongqing, showing specific enrichment of Hg in WLFZ due to contamination in the TGR. The surface soils have low SOC, with an average value of 8.10 \u00b1 3.90 g kg\u22121. Moreover, THg content showed consistent distribution with the SOC in WLFZ, with a significantly positive correlation (R = 0.52, p &lt; 0.01, n = 242). THg storage (201.82 \u00b1 103.46 g ha\u22121) in the surface soils was also significantly positively correlated with the SOC storage (R = 0.47, p &lt; 0.01, n = 242). The reduced SOC sequestration, due to the periodical alternative \u201cflooding\u2013draining\u201d and frequent reclamation and utilization of WLFZ, decreased the Hg adsorption in soil. Those might result in the re-release of Hg into waters when WLFZ is flooded. Therefore, more attention should be directed towards Hg cycling and the consequent environmental risks in the TGR region.<\/jats:p>","DOI":"10.3390\/ijerph20043681","type":"journal-article","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T03:29:06Z","timestamp":1676863746000},"page":"3681","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Organic
