Objective: To evaluate the drinking water quality in cities and towns in Xinjiang.
Methods: The testing data of 6543 water samples from the dry season and the wet season in 2023 were selected, and the drinking water quality in Xinjiang was evaluated and analyzed by using the Nemerow pollution index, the worst factor discriminant method and the weighted average method to calculate the comprehensive water quality index.
Results: The comprehensive index of drinking water quality in Xinjiang was 0.36 ± 0.39, and the quality rate was 98.58 %. The water quality in the wet season (0.28 ± 0.45) was better than that in the dry season (0.44 ± 0.28), and water quality in the urban area (0.34 ± 0.20) was better than that in the rural area (0.37 ± 0.28). The water quality of conventionally treated water (0.35 ± 0.30) and other treatments (0.36 ± 0.21) was better than that of nontreated water (0.42 ± 0.84), and the water quality of the disinfected water (0.35 ± 0.29) was better than that of the nondisinfected water (0.39 ± 0.54). The water quality of deep wells (0.35 ± 0.25), rivers (0.35 ± 0.37), springs (0.35 ± 0.21), reservoirs (0.37 ± 0.28), others (0.37 ± 0.24), and shallow wells (0.37 ± 0.31) was significantly better than that of streams (0.90 ± 2.40) ().
Conclusion: The drinking water quality in Xinjiang is generally good, and the water can be safely drunk. Drinking water quality is mainly affected by the water period, sampling type, water source classification, and water supply method. Lakes, deep wells and rivers are the ideal drinking water sources in Xinjiang.

The present study evaluated the performance of a full-scale gravity-driven membrane filtration system with passive hydraulic fouling control (PGDMF) for drinking water treatment in a small community over a 3-year period. The PGDMF system consistently met the design flow and regulated water quality/performance parameters (i.e.

This study is aimed at evaluating the quality and safety of two traditional fermented dairy products commonly found in Lebanon (Ambarees and Kishk in its dry and wet forms) by detecting foodborne pathogens and indicator microorganisms. Additionally, it seeks to identify the strengths, weaknesses, opportunities, and threats to quality and the production level. A total of 58 random samples (duplicated) including goat milk ( = 16), dry Kishk ( = 8), wet Kishk ( = 8), and Ambarees ( = 26) were collected from individuals who both farm and process these products.

Biofloc technology is an aquaculture production system that has gained popularity with tilapia production. Probiotics provide benefits for the host and/or aquatic environments by both regulating and modulating microbial communities and their metabolites. When a probiotic feed is combined with a biofloc system, the production amount may be improved through better fish growth, disease resistance, and/or improved water quality by reducing organic matter and stabilizing metrics such as pH and components of the nitrogen cycle.

High levels of nitrogen compounds can lead to acute toxicity in aquatic organisms. Ammonia, a by-product of protein breakdown, is the most prevalent contaminant in freshwater environments. Increasing salinity in water sources can cause fluctuations in salinity levels within breeding ponds.

Tobacco, being a globally cultivated crop, holds significant social and economic importance. Tobacco plants are susceptible to the adverse effects of heavy metals (HMs), particularly cadmium (Cd), which hinders root development, disrupts water balance, and impedes nutrient absorption. Higher concentrations of HMs, especially Cd, naturally accumulate in tobacco leaves due to complex interactions within the plant-soil continuum.
