Special Issue Information

Dear Colleagues,

Water is one of the most important resources on Earth. The quantity and quality of water resources are essential to the health of the population, and to all sectors of the economy, making it a determining factor in society’s standard of living. Urban wastewater usually contains different substances (e.g., chemicals and mixtures of chemicals) that can be toxic and have a negative effect on environmental resources. Urban wastewater treatment and environmental sustainability are the only ways to conserve natural resources, including water, and protect global ecosystems. 

The aim of this Special Issue of Water is to present the latest reports related to urban wastewater treatment and environmental sustainability. Authors are encouraged to present their research and review papers on urban wastewater treatment, as well as articles on wastewater toxicity and estrogenicity.

Dr. Dorota Olejnik

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. Water 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 2600 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.

This article presents the results of a study on the oestrogenicity and androgenicity of urban wastewater in Lodz, and the possibility of their removal by the Group Wastewater Treatment Plant (GWWTP). Wastewater samples were taken at five points of the sewer system in the city and at the inlet and outlet of the GWWTP. The study was conducted using Yeast Oestrogen Screen (YES)/Yeast Androgen Screen (YAS) tests, which allow a general assessment of the content of compounds with (anti-)oestrogenic and (anti-)androgenic effects in wastewater, without identifying specific substances. Wastewater samples taken from the sewage network did not show (anti-)oestrogenic activity, while oestrogenic and antagonistic properties to androgens were detected in most of them. In the influent of the treatment plant, oestrogen agonistic activity was detected only in one sample (oestrogen equivalent—EEQ equal to 1.31 × 105 ng 17 β–oestradiol/L) and was 100% removed. The purification efficiencies in GWWTP for oestrogen and androgen antagonistic activity were 51.5–99.2% and 39.4–47.1%, respectively. Although no oestrogenic activity was detected in general wastewater in Lodz, observed high-antagonistic–androgenic activities may adversely affect the water body and cause, among others, the feminization of fish, especially in the case of discharge of untreated wastewater by combined sewer overflows.

Due to the agricultural and industrial activities in rapidly urbanized basins, nitrogen (N) inputs have increased significantly, causing a variety of environmental issues. These challenges require an accurate assessment of the contributions of the driving factors, particularly in the Chaohu Lake Basin, which faces the double pressures of urban expansion and agricultural production. The research shows: (1) From 1990 to 2018, the trajectory of net anthropogenic N inputs (NANI) exhibited a three-stage pattern (uptrend stage, fluctuation stage, and downtrend stage), with an average value of 13,482 kg N km−2 year−1. The primary source was fertilizer N application, which made up approximately 79% of the NANI. Human food and animal feed imports, biological nitrogen fixation, and atmospheric N deposition composed 8%, 6%, and 6%, respectively. (2) Rapid urbanization enhanced the NANI in a short time stage. However, long-term analysis had shown a declining trend in nitrogen inputs, indicating that urbanization could improve fertilizer efficiency and introduce cleaner energy sources. (3) The NANI in urban watersheds were estimated at 20,700 kg N km−2 year−1, which was 3.4 times higher than in agricultural watersheds. Fertilizer N application was used in urban watersheds, as well as human food and animal feed imports. Urbanization drove the N input of food and feed mainly in urban watersheds but had no influence in agricultural watersheds and mixed watersheds. Since urban basins were the main source of nitrogen inputs, it was crucial to support environmental management efforts to reduce N pollution. Full article
