Special Issue Information

Dear Colleagues,

Emerging contaminants (ECs) are a large class of compounds such as persistent organic pollutants (POPs), microplastics, endocrine disrupters and antibiotics, etc. Toxicological data reveal that these contaminants present high ecotoxicity, long persistence and do not biodegrade easily. The worldwide detection and occurrence of ECs in various environmental media, especially in water, have been reported. As our knowledge about them deepens, there becomes an urgent need to develop highly effective treatment techniques and set regulatory standards in order to solve to problem of water pollution by ECs.

The “highly effective” in highly effective treatment techniques not only refers to the high removal efficiency of ECs, but also that the technique must pose low or even no ecological risks during the whole treatment process. Given this, transformation behaviors including the analysis of the removal kinetics and mechanisms as well as ecological risk assessments will be considered for this Special Issue. Therefore, this Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) focuses on green and environmentally friendly treatment techniques for ECs. New research papers, reviews, viewpoints, case reports, and conference papers are welcome in the Special Issue. Papers dealing with new approaches to ECs’ standards or risk assessments and management are also welcome. Other manuscript types accepted include methodological papers, position papers, brief reports, and commentaries. A broad outline of this Special Issue's scope includes, but is not limited to:

  1. New analysis methods for ECs;
  2. The occurrence of new ECs in water;
  3. Environmental behaviors and adverse effects of ECs and their potential metabolites;
  4. Highly effective treatment techniques for ECs;
  5. Targeted/non-targeted screening techniques for the transformation intermediates and end products of ECs;
  6. Toxicity identification evaluation and effect-directed analysis of ECs and their transformation products; 
  7. Theoretical calculations of ECs.

We are looking forward to receiving your contributions.

Antibiotics and pesticides, as well as various emerging contaminants that are present in surface waters, raise significant environmental concerns. Advanced oxidation processes, which are employed to eliminate these substances, have demonstrated remarkable effectiveness. However, during the degradation process, by-products that are not completely mineralized are generated, posing a substantial risk to aquatic ecosystem organisms; therefore, it is crucial to assess effluent ecotoxicity following treatment. This study aimed to assess the toxicity of effluents produced during the removal of amoxicillin and glyphosate with a Fenton-type process using a laminar structure catalyzed with iron (Fe) and copper (Cu). The evaluation included the use of Daphnia magna, Selenastrum capricornutum, and Lactuca sativa, and mutagenicity testing was performed using strains TA98 and TA100 of Salmonella typhimurium. Both treated and untreated effluents exhibited inhibitory effects on root growth in L. sativa, even at low concentrations ranging from 1% to 10% v/v. Similarly, negative impacts on the growth of algal cells of S. capricornutum were observed at concentrations as low as 0.025% v/v, particularly in cases involving amoxicillin–copper (Cu) and glyphosate with copper (Cu) and iron (Fe). Notably, in the case of D. magna, mortality was noticeable even at concentrations of 10% v/v. Additionally, the treatment of amoxicillin with double-layer hydroxides of Fe and Cu resulted in mutagenicity (IM ≥ 2.0), highlighting the necessity to treat the effluent further from the advanced oxidation process to reduce ecological risks.

Rice–duck and rice–crayfish co-culture patterns can increase soil productivity and sustainability and reduce the use of chemical pesticides and fertilizers, thereby reducing the resulting negative environmental impacts. However, most studies have focused on the rice–duck and rice–crayfish binary patterns and have ignored integrated systems (three or more), which may have unexpected synergistic effects. To test these effects, a paddy field experiment was carried out in the Chaohu Lake Basin, Hefei city, Southeast China. Four groups, including a rice–duck–crayfish ecological co-culture system (RDC), idle field (CK), single-season rice planting system (SSR), and double-season rice planting system (DSR), were established in this study. The results showed that the RDC improved the soil physical properties, fertility, humus content, and enzyme activity. In the RDC system, the soil total nitrogen content ranged from 8.54% to 28.37% higher than other systems in the 0-10 cm soil layer. Similar increases were found for soil total phosphorus (8.22–30.53%), available nitrogen (6.93–22.72%), organic matter (18.24–41.54%), urease activity (16.67–71.51%), and acid phosphatase activity (23.41–66.20%). Relative to the SSR treatment, the RDC treatment reduced the total losses of nitrogen and phosphorus runoff by 24.30% and 10.29%, respectively. The RDC also did not cause any harm to the soil in terms of heavy metal pollution. Furthermore, the RDC improved the yield and quality of rice, farmer incomes, and eco-environmental profits. In general, the RDC can serve as a valuable method for the management of agricultural nonpoint-source pollution in the Chaohu Lake area and the revitalization of the countryside. Full article
