Special Issue Information

Dear Colleagues,

At present, the environment is becoming fragile due to intensive human activities. We face various challenges from air and water pollution, marine plastic litter pollution, excessive solid waste around cities and villages, climate change, and others. These challenges threaten ecological integrity as well as human health. The present Special Issue focuses on the topic of Environmental Toxicology and Risk Assessment, including the toxicological effects and responses, molecular mechanisms, toxicological pathways, and potential ecological/health risks in organism exposure to various pollutants, particularly these emerging pollutants in all environmental compartments. We welcome submissions in the form of original research articles, short communications, comments, and reviews. We encourage new theories, analytical methods, and risk assessment frameworks. Particularly, novelty is the most important. Our efforts should contribute to understanding the environmental fates of various pollutants and filling in the present knowledge gaps. These works should provide unique perspectives and could be used as a meaningful reference for other researchers and scientists.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Polycyclic aromatic hydrocarbons (PAHs) are recognized as carcinogens that pose a severe threat to human health. Research on the temporal variation of PAHs was confined to monthly and seasonal investigations, and a longer timescale study remained inadequate until recently. Therefore, this study focuses on the decadal variation of PAHs in environmental media contaminated by a coal gangue dump in the Jiulong Coal Mine, Fengfeng, China. The results show that the total concentrations of PAHs have sharply declined compared to the past. The result of the paired-sample t-test indicates that several individual PAHs have obviously changed in concentration with statistical significance (p < 0.05). Moreover, proportions of medium-molecule weight PAHs increase with statistical significance (p < 0.01) when compared to the past. Various diagnostic ratios suggest that PAHs in previous samples are mainly derived from weathering products of coal gangue and vehicle exhaust, while PAHs in the present samples are dominated by those originating from pyrogenic sources. Calculation of incremental lifetime cancer risks (ILCRs) indicates high carcinogenic risk despite a considerable decrease in ILCR values by 2 to 3 orders of magnitude. It shows that recent measurements conducted by the local government do weaken the contamination of coal gangue dumps, but more attention to pyrogenic PAHs is necessary. Full article
