Summary: The study focused on investigating groundwater and subsoil contamination within the coastal aquifers of Arogbo in Ondo State, Nigeria. The results showed that the aquifer is shallow with water table depths ranging from 0.37 to 1.20 m, and the water quality has been greatly impaired by contaminants such as iron, manganese, and brackish water. The study concluded that terrestrial sources of iron and manganese were the major contaminants responsible for the high level of coloration of surface water and groundwater in the area, posing serious health hazards to residents.

Summary: This paper comprehensively studied the distribution patterns, key controlling factors, potential ecological risks, and fluxes to the ocean of trace metals (As, Ba, Cr, Cd, Fe, Mn, Pb, and Zn) in a coastal deep sandy aquifer. The results showed clear zonation of trace metals in relation to the mixing extent between seawater and terrestrial freshwater. Seawater-groundwater interactions significantly affected the concentrations of trace metals, and the tide-driven saline water zone was vulnerable to enrichment of trace metals due to oceanic environments and anthropogenic activities. Trace metal fluxes via submarine groundwater discharge (SGD) significantly contributed to the total input into the sea, with potential impacts on coastal environments. Our study highlights the importance of seawater-groundwater interactions in trace element cycling in coastal sandy aquifers.

Summary: In this study, thirty sediment samples were collected from the Gohar Rood River in Iran to evaluate the levels of different elements and their potential environmental risks. Using ICP-MS analysis, fifteen elements were measured, and it was found that chromium concentrations exceeded the Severe Effect Level (SEL) at all sampling sites. Zinc, manganese, cobalt, and chromium showed moderate contamination based on pollution index, modified pollution index, and enrichment factor. The modified hazard quotient indicated varying degrees of pollution severity for some elements. Regression analysis revealed that agricultural runoff, domestic, and municipal sewage were the main sources of zinc, copper, lead, antimony, and molybdenum in the riverine sediment. Additionally, the BCR fractionation scheme indicated medium to high risks to the local environment from manganese, cobalt, and zinc.

Summary: Tides and storm surges have significant effects on groundwater circulation and fluxes in coastal aquifers, however, few studies have investigated the response of coastal aquifers to both forces. This study uses three years of hydraulic head observations in a barrier island to analyze the inland propagation of fluctuations caused by tidal changes and storm-induced surge and wave-driven setup. The study finds that the amplitude attenuation rate of hydraulic head fluctuations is higher than the inland increase in phase lag for tidally-driven fluctuations, and tidal fluctuations deeper in the aquifer lead those nearer the surface, while storm surges have similar rates of amplitude attenuation and phase lag increase and result in depth uniform hydraulic head fluctuations.

Summary: This study developed a steady-state analytical solution using the single potential approach to quantify the maximum safe pumping rate in sloping unconfined coastal aquifers. It found that coastal aquifers with a higher aquifer bed towards inland yield a higher maximum safe pumping rate compared to those with a horizontal aquifer base. Neglecting the aquifer base slope can lead to significant errors in estimating the maximum safe pumping rate. The results provide valuable insights into the effect of the aquifer base slope on pumping-induced seawater intrusion in coastal aquifers and offer a useful tool for quick assessment.

Summary: The study investigated the concentration of total dissolved mercury (Hg-T) in groundwater in the coastal parts of Urmia aquifer in Iran, identifying geological weathering as a main source of mercury. One sample exceeded the maximum contaminant level recommended by WHO. The distribution of water samples on the Piper diagram indicated Ca-Mg-HCO3 facies predominance, while the positive correlation of Hg-T with various elements suggested geological formations as a significant source of mercury. Water samples in Eh-pH regions showed potential microbial activity related to mercury methylation and mineralization, indicating sulfate reduction processes and limited anaerobic conditions. The study also found some Hg-bearing species in nonequilibrium geochemical conditions and speculated on the role of Fe-bearing minerals in reducing Hg(II) to Hg(0).

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
