Special Issue Information

Dear Colleagues,

Water resources are essential for the ecological environment and human health. Water quality is one of the most important issues and exerts a critical role on ecosystem behavior. Ecological risks reflect the intensity of external risks faced by ecosystems and their ability to resist these risks. These factors may include natural disasters, climate change, pollution, biological invasions, over-exploitation, and resource overuse. The health and stability of ecosystems are crucial for the survival and development of human society. An increase in ecological risks may lead to severe environmental problems and have adverse effects on human health, economy, and society. Therefore, an in-depth understanding of the features and evaluation of water’s ecological health are the primary and challenging issues that need to be faced to ensure the needs of ecosystems and humans. However, there is always uncertainty in any water quality risk assessment, and it is necessary to better understand the integrity and complexity of ecosystems, thus formulating more effective protection and management strategies. The topics of interest to this Special Issue may be related, but are not necessarily limited, to the following: water ecological risk assessment techniques; water quality criteria and standards; national environmental management policies regarding water; early warning systems of river and lake pollutants; and the analysis and characterization of pollutants in aquatic environments.

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 250 words) can be sent to the Editorial Office for assessment.

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. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Freshwater quality criteria (FWQC) are essential scientific thresholds established to protect human health and aquatic ecosystems, serving as the foundation for water quality standards, environmental risk management, and pollution control. The latest research advancements were summarized, including the screening of priority pollutants for FWQC and the theory and methodology for environmental criteria in China in the last decade. The potential work has been meticulously analyzed and discussed concerning FWQC to be conducted in the short-term future. The possible prioritized list of pollutants for FWQC should be concerned with including nine categories of heavy metal ions, three categories of non-metal ions, and five categories of organic compounds in the short-term future research. The guidelines for deriving FWQC for the protection of human health for organoleptic effects and for sediment need to be modified and emphasized to ensure the safety of drinking water sources, address issues related to black and odorous surface water, and protect the biodiversity of benthic organisms. Toxicity data, water quality parameters, exposure data, and the geographical distribution of freshwater species should be systematically collected to support the development of FWQC in China. The potential applications of FWQC were also explored in the evaluation and formulation of WQS, ecological risk assessments, and the management of environmental emergencies and damage assessments to support environmental protection and management in China.
