“…The observed temperature and hydration effects on adsorption are of practical importance. Adsorption of phosphate groups, , pharmaceutical substances, , and DNA − on silica, removal of impurities from polluted water, − and environmental safety of sediments , are humidity-sensitive. Another potentially important type of guests are molecules, which exhibit self-assembling ability in aqueous solutions. − Such molecules have remained outside the scope of this work.…”

Thermal and hydration effects on the mobility of compact and branched organic molecules and a bulky pharmaceutical substance loaded in submonolayer amounts onto mesoporous silica have been elucidated using 1 H and 31 P solid-state NMR. In all cases, the ambient hydration has a stronger effect than an increase in temperature to 370 K for water-free silica. The effect of hydration depends on the guest and ranges from complete solvation to a silica−water−guest sandwich structure to a silica−guest/silica−water pattern. The mobility of the guests under different conditions has been described. The specific structure of the MCM-41 surface allows one to study very slow surface diffusion, a diffusivity of about 10 −15 −10 −16 m 2 /s. The data reported are relevant to any nonfunctionalized silica, while the method used is applicable to any phosphor-containing guest on any host.

“…Fluctuations in concentration with depth are observed, although an irregular trend is observed among the four core sediments as soil depth increases. The spatial distribution of heavy metals in coastal sediments is in uenced by both natural factors and human activities, such as agriculture, transportation e uents, domestic waste, and industrial wastewater, as discussed by Yakovlev et al (2020).…”

Coastal regions are especially susceptible to both natural and human-induced pressures, and it is crucial to evaluate these pressures. This research aims to investigate the monitoring of human activities through river discharges in order to identify potential ecological risks and examine the long-term changes in metallic contamination in Monastir-Sayada. To accomplish this, four sediment samples were collected from various locations along the Monastir coast, specifically near the source of pollution, to analyse the concentrations of heavy metals like Zinc (Zn), Cadmium (Cd), Copper (Cu), Lead (Pb), Manganese (Mn), Nickel (Ni), and Iron (Fe). The findings indicate that the average concentrations of these metals in the sediment cores followed a descending order of Fe > Zn > Mn > Cu > Cd in front of the Monastir effluent, Fe > Mn > Zn > Pb > Cd > Cu > Ni in the effluent at Frina region, Fe > Mn > Zn > Cd > Ni > Pb > Cu in the Melah stream, and Fe > Mn > Cd > Zn > Cu in front of the Essouk stream at Lamta. Based on the enrichment factor (EF) and contamination factor (CF), the long-term evolution of the Monastir-Sayada coast is considered highly polluted for Pb and Cd, posing a relatively high potential ecological risk. The heavy metals are believed to originate from similar human activities, as indicated by the principal component analysis (PCA) and cluster analysis (CA). Pollution from heavy metals can have long-lasting effects on coastal sediments, emphasizing the importance of preventing such pollution in the first place.

“…The heavy metal concentrations are compared with the standard limits for coastal sediments based on the Sediment Quality Guidelines (SQG) established by USEPA [15]. The distribution of heavy metals in coastal sediments is greatly influenced by natural and anthropogenic factors [29], [30]. Any contaminants are transported via drainage system into coastal and marine environment that serve as natural sink for the accumulation of heavy metal burden.…”

This article discusses the geophysical investigation of sediment and the status of heavy metals pollution in the coastal sediment from Usukan Beach, Kota Belud Sabah Malaysia. Study area is located at the northwest coast of Sabah which is bounded by the South China Sea and made up of Crocker Formation which age from Late Eocene to Early Miocene, Wariu Formation with Middle Miocene age and Quaternary Alluvium. This study using geoelectrical method namely electrical resistivity (IR) and induced polarization (IP) to measure the thickness of sediment and the parent rock lithology respectively. Whereas the heavy metal contents were measured using the Inductively Coupled Plasma-Optical Emission Spectrometry (ICP- OES). Three sets of subsurface cross-sections were conducted for the geophysical survey and covered the depth around 37 meters for all the survey line. The result of geophysical survey shows that the alluvium quaternary deposits in the low-lying flat area have a thickness up to 13 metres and overlie the mudstone dominated rock of the Crocker Formation. The geochemical analysis shows a decreasing ranking order of elemental concentrations Fe>Mn>Zn>Cu>Pb>Cr>As. The analyses show all elements are within the background values and acceptable standard limits of the Sediment Quality Guidelines (SQG) by USEPA for coastal sediments. The assessment of heavy metals revealed only minimal degree of pollution in the coastal sediments.
