The present study was undertaken to investigate the toxic effect of ground water fluoride (F) on motility, abnormality, and antioxidant status of spermatozoa. Treatment of ground water F with epididymal sperm suspension caused complete loss of sperm motility and decrease in the activities of superoxide dismutase (SOD) and catalase (CAT) and increase in the concentration of malondialdehyde (MDA) and abnormality of spermatozoa at 15 and 30 min time intervals. Further, incubation of spermatozoa with ground water F for 5, 10, and 15 min time intervals significantly reduced the sperm motility and activities of SOD and CAT and increased the concentration of MDA and abnormality of spermatozoa. The study revealed that F-induced effect on sperm motility and antioxidant status is time dependent. Increase in oxidative stress and concomitant decrease in motility of spermatozoa in ground water F clearly indicates that F-induced oxidative stress affected the sperm motility. The present study for the first time demonstrated the toxic effect of ground water F on spermatozoa at shorter duration of exposure, which affects the capability of spermatozoa in fertilization.

Both over-exploitation and exploitation reduction of groundwater can alter the conditions of groundwater recharge and discharge, thereby impacting the overall quality of groundwater. This study utilizes hydrogeochemical methods and statistical analysis to explore the spatial and temporal evolution characteristics and influencing factors of groundwater chemistry in the saline-freshwater funnel area of Hengshui City under exploitation reduction. The results showed that: With the exception of the deep freshwater funnel area in the western region, which exhibits a trend of water quality deterioration (Cl accounted for more than 25%), groundwater quality in the other funnel areas demonstrates an improving trend (HCO[Formula: see text] accounted for more than 25%).

The presence of lead ion (Pb) in groundwater poses a serious risk to human health, even at low levels. Therefore, it is essential to develop a new strategy for both selective detection and effective removal of Pb in groundwater, which has been rarely reported. Here, we developed a multi-functional chitosan-based fluorescent sensing membrane (CM-L/CG) by using a casting method for the sensitive/selective detection and removal of Pb in groundwater.

The present study evaluates for the first time the seasonal performance of an innovative green groundwater treatment. The pilot plant combines microalgae-bacteria treatment and a cork-wood biofilter to reduce nitrates, pesticides, antibiotics (ABs), and antibiotic resistance genes (ARGs) from groundwater. Groundwater had nitrate concentrations ranging from 220 to 410 mg/L, while ABs (sulfonamides and fluoroquinolones) and pesticides (triazines) were detected at concentrations ranging from a few ng/L to 150 ng/L.

Vanadium oxides nanoparticles (VO-NPs) as emerging functional materials are widely applied in high-technology industries. However, their environmental behaviors remain largely known. In this study, the migration of three common VO-NPs (VO VO, and VO) in saturated porous media has been investigated.

Groundwater-dependent ecosystems in areas with industrial land use are at risk of exposure to a PFAS chemicals. We investigated one such system with several known PFAS source areas, where high and low permeability sediments (glacial) coupled with groundwater-lake and groundwater/surface-water interactions created complex 'source to seep' dynamics. Using heat-tracing and chemical methods, numerous preferential groundwater discharge zones were identified and sampled across the upper Quashnet River stream-wetland system in Mashpee, MA, USA, downgradient of Joint Base Cape Cod (JBCC).
