The continued development in agriculture, the rapid growth of industrialization, and last but not least, the increase in the global population adversely affects the environment. The availability of drinking water decreases every year with the rise in water pollution, which is the consequence of the failure of conventional approaches to the water treatment process. This review will provide a comprehensive and detailed analysis of the electrochemical water treatment processes, as these techniques have several benefits over conventional methods, such as being cost-effective, easily applicable, selective, and broad applicability. This review starts by discussing the traditional methods. It explains their limitations and finishes the introductory part by presenting all the benefits of the electrochemical method over the conventional method for water treatment. Then, the discussion will be carried out on the individual electrochemical method with their detailed analysis of the selected approach, selected material, and optimized parameters for analysis. The elaborative study was targeted, and the different coupled systems, their analysis parameters, and derived removal efficiencies were given in tabular form. In the last section of the article, the conclusive statements present the prospects of the electrochemical method for water treatment.

Background: "Active" heat acclimation (exercise-in-the-heat) can improve exercise performance but the efficacy of "passive" heat acclimation using post-exercise heat exposure is unclear. Therefore, we synthesised a systematic review and meta-analysis to answer whether post-exercise heat exposure improves exercise performance.

Methods: Five databases were searched to identify studies including: (i) healthy adults; (ii) an exercise training intervention with post-exercise heat exposure via sauna or hot water immersion (treatment group); (iii) a non-heat exposure control group completing the same training; and (iv) outcomes measuring exercise performance in the heat (primary outcome), or performance in thermoneutral conditions, V̇Omax, lactate threshold, economy, heart rate, RPE, core temperature, sweat rate, and thermal sensations.

To investigate the bacterial community structure and physicochemical characteristics of different types of Daqu in the Binzhou region, this study employed traditional pure culture methods, high-throughput sequencing technology, and conventional physicochemical assays for analysis. The research results indicate that Enterococcus faecium and Bacillus licheniformis emerged as the main LAB and Bacillus species in Daqu from Binzhou region, respectively. In addition, high-throughput sequencing revealed significant differences in bacterial community structure between the two types of Daqu (P < 0.

The characterization of tunnel wash water (TWW) from 12 Norwegian tunnels showed very high concentrations of total suspended solids (TSS), metals, and polycyclic aromatic hydrocarbons (PAHs). Iron (Fe), aluminum (Al), and manganese (Mn) were mainly particle-associated. They are efficiently removed by sedimentation, while the dissolved concentrations of toxic metals like Cu, Zn, and As did not change.

Purpose: Cryptosporidium spp. and Giardia duodenalis are zoonotic protozoan parasites that are widely seen in domestic and wild animals worldwide. While these pathogens, which affect the digestive system of the hosts, cause high economic losses in animal breeding, they are also considered an important public health problem.
