The modified vermiculite-montmorillonite was added to remediate the potentially toxic trace element (PTE) Hg present in soil containing coal gangue. Pot experiments were conducted to analyze and compare the pH values, Hg contents and Hg species present in coal gangue-containing soil, with and without the modified materials added, to determine whether the addition of modified materials had an effect on the growth of Brassica chinensis L. Results showed that with the addition of 35 g\u00b7kg\u22121 modified vermiculite-montmorillonite, the pH of soil increased by a value of 0.79, compared with that in the control group. When 15 g\u00b7kg\u22121 was added, the concentration of Hg in soil decreased by 98.2%. The addition of modified materials promoted the transformation of Hg in soil from a bioavailable form to an unavailable form; that is, the content of the residual form increased. The plant height and biomass of Brassica chinensis L. also increased, which indicated that the addition of modifiers can increase soil productivity, reduce the effects of PTEs on organisms in soil, and promote plant growth. Therefore, the addition of modified vermiculite-montmorillonite can achieve remediation of coal gangue-containing soil.<\/jats:p>","DOI":"10.3390\/molecules27165340","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T21:30:34Z","timestamp":1661203834000},"page":"5340","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Remediation of Soil Mercury by Modified Vermiculite-Montmorillonite and Its Effect on the Growth of Brassica chinensis L."],"prefix":"10.3390","volume":"27","author":[{"given":"Chang","family":"Li","sequence":"first","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"},{"name":"Anhui Province Engineering Laboratory for Mine Ecological Remediation, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuchen","family":"Li","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"},{"name":"Anhui Province Engineering Laboratory for Mine Ecological Remediation, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hua","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"},{"name":"Anhui Province Engineering Laboratory for Mine Ecological Remediation, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunlu","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"},{"name":"Anhui Province Engineering Laboratory for Mine Ecological Remediation, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liugen","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"},{"name":"Anhui Province Engineering Laboratory for Mine Ecological Remediation, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"112321","DOI":"10.1016\/j.ecoenv.2021.112321","article-title":"Study of the micromorphology and health risks of arsenic in copper smelting slag tailings for safe resource utilization","volume":"219","author":"Zhang","year":"2021","journal-title":"Ecotoxicol.
