Groundwater Nitrate Contamination in Arid Areas of Haidong

Water, Год журнала: 2023, Номер 15(23), С. 4067 - 4067

Опубликована: Ноя. 23, 2023

With the rapid development of cities in northwest China, there has been an increasing focus on groundwater pollution plateau cities, specifically common occurrence nitrate pollution. The special climatic, geological, and geomorphological characteristics river valley contribute to distinct chemical characteristics. Therefore, formation evolution process contamination differs from that plain cities. To explore these issues, we conducted analysis eight major ions various groups water samples obtained rivers, springs, Haidong. By utilizing factor correlation analysis, were able identify chemistry Our findings reveal Haidong are primarily controlled by rock weathering, mineral dissolution, evaporation, leading highly mineralized groundwater. Additionally, excessive content certain areas is a result domestic sewage discharge agricultural fertilizer use, exceeding Chinese drinking health standards. Furthermore, for located valleys, geological structure significantly impacts different regions. Areas with obstructed flow tend have higher levels, whereas regions unobstructed experience lower concentrations. Notably, shallow more vulnerable compared deep This study holds great significance understanding highland

Deciphering pollution sources and mechanisms controlling groundwater chemistry in a typical dense agricultural plain on Yungui Plateau

Water Environment Research, Год журнала: 2024, Номер 96(12)

Опубликована: Дек. 1, 2024

Groundwater is a critical resource for economic growth and livelihoods in the dense agricultural plains of plateaus. However, contaminations from various sources pose significant threats to groundwater quality. Understanding contamination mechanisms hydrochemical control essential sustainable development agriculturally intensive plains. This research utilizes 23 datasets chemical measurements apply hierarchical clustering analysis, positive matrix factorization, analysis techniques. Through these methods, study identifies deciphers within representative plain region Yungui Plateau. The finds indicate that primarily derives rainfall occurred surrounding mountains. During long underground flow process, undergoes water-rock interactions ion exchanges with lithological strata, resulting formation distinct types. As it traverses regions influenced by human activities, encounters varying levels types contamination. Consequently, there notable variation quality across different areas plain. dominated faces HCO

Changing Soil Water Content: Main Trigger of the Multi-Phase Mobilization and Transformation of Petroleum Pollution Components—Insights from the Batch Experiments

Water, Год журнала: 2024, Номер 16(13), С. 1775 - 1775

Soil moisture content continuously alters the types and forms of petroleum organic pollutants in soil through processes such as dissolution, convection, dilution, forming complex migration transformation a water–air–soil–NAPL system. Field investigations traditional indoor simulation experiments have difficulty terms accurately diagnosing state different due to influence environmental factors controlling single factors. Batch were conducted simulate mobilization differentiation under water content. The results show that (1) residual components is lowest coarse sand highest clay, which mainly affected by particles; meanwhile, saturation value octanoic acid largest, toluene smallest, determined their viscosity volatility. (2) infiltration are properties medium characteristics. Due its small particle size strong adsorption, clay has (28.8%). This can even be more than twice (13.3%). For components, saturations lowest, respectively (taking fine an example: 25.3% 13.2%), with relatively large difference, solubility. (3) As free phase migrate freely, it transformed most rapidly pores. changes dissolved each component tend gentle. volatility, viscosity, particles, pore cosmid content; degree change ordered follows: > cyclohexane hexadecane acid.
