Here, we optimized a purge-trap method that enabled efficient separation and isotopic analysis of IHg and MeHg in marine organisms. Applying this method to surface and benthic organisms collected from the Bohai Sea in winter and summer, we reveal distinct seasonal and habitat-specific Hg dynamics. Surface organisms primarily accumulated MeHg that had undergone photodemethylation in the water column, while benthic organisms assimilated a mixture of photodegraded water-column MeHg (64\u201380%) and nonphotodegraded MeHg produced in sediments (20\u201336%). In vivo MeHg demethylation was substantially enhanced in surface organisms during summer, contributing \u223c36% of the organismal IHg pool. Species-specific isotope signatures further suggest that methylation of IHg in sediments is a major source of MeHg to the water column, with \u223c14\u201319% of it being photodegraded before biological uptake. Together, these findings provide new mechanistic insight into coastal Hg cycling and advance the isotopic framework for assessing ecological risks associated with marine Hg exposure.<\/jats:p>","DOI":"10.1021\/acs.est.5c18280","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T14:02:08Z","timestamp":1786370528000},"page":"23369-23379","source":"Crossref","is-referenced-by-count":0,"title":["Seasonal\nand Habitat-Specific Mercury Cycling in Coastal\nBiota Revealed by Species-Specific Isotopes"],"prefix":"10.1021","volume":"60","author":[{"given":"Songjing","family":"Li","sequence":"first","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7261-8377","authenticated-orcid":true,"given":"Ruoyu","family":"Sun","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowei","family":"Chen","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhao","family":"Wang","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0513-883X","authenticated-orcid":true,"given":"Chao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengfei","family":"Li","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Liu","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3413-9700","authenticated-orcid":true,"given":"Wang","family":"Zheng","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7299-0355","authenticated-orcid":true,"given":"Jiubin","family":"Chen","sequence":"additional","affiliation":[{"name":"Tianjin University , , , ,","place":["Tianjin, China, 300072"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,10]]},"reference":[{"issue":"5","key":"2026083119445236100_cit1","doi-asserted-by":"publisher","first-page":"877","DOI":"10.1007\/s13280-023-01831-6","article-title":"Our Evolved\nUnderstanding of the Human Health Risks of Mercury","volume":"52","author":"Basu","year":"2023","journal-title":"Ambio"},{"issue":"11","key":"2026083119445236100_cit2","doi-asserted-by":"publisher","first-page":"5969","DOI":"10.1021\/acs.est.7b00451","article-title":"Total Mercury\nReleased to the Environment\nby Human Activities","volume":"51","author":"Streets","year":"2017","journal-title":"Environ.
