“…Special investigations on the toxicity of several compounds of zinc can be found . The inhalation of silica nanoparticles and its effects in living organisms is subject of investigations. , For these reasons, it is of some interest to look at what will happen if a colloidal particle comes in contact with a liquid. We have studied the interaction of oxidic nanoparticles with water in recent investigations. − The solubility of the bulk oxides is commonly found to be in the region of nmol/L to mmol/L.…”

Dissolution experiments are carried out with nanoparticles of barium sulfate in water. An unusual concentration-time behavior is observed. A concentration maximum is measured at the very beginning of the dissolution process. This maximum considerably exceeds the saturation concentration of bulk material. The maximum concentration is followed in time by a decrease of the concentration until the saturation concentration of the bulk material is obtained. This behavior is called kinetic size effect and it is a characteristic of nanoscale particles in general. The colloidal system can be modeled theoretically by thermodynamic and kinetic considerations that cover all processes which may occur in the system: nucleation, particle growth, Ostwald ripening, and dissolution of particles. It has been shown that only the outer surface of the particles is responsible for the dissolution kinetics; it is suggested that the surface of micropores yields no contribution. The dissolution curves observed experimentally follow from the model considerations. It is possible by comparison of experiment and theory to estimate the saturation concentration influenced by the ionic strength in the solution. This effect can be well described by the extended Debye-H€ uckel law. The measured numerical values of the saturation concentrations are found to be in the range of 4-14 μmol L -1 and therefore in the vicinity of the solubility product of BaSO 4 . The saturation activity at infinite dilution (I f 0) is a Ba ¥ = 2.43 ( 0.12 μmol L -1 and the thermodynamic solubility product is K L ¥ = 10 -11.23 . Furthermore, the model calculations provide the possibility to estimate the interfacial tension of the system nanoparticle-solution. The numerical value of 1.1 N m -1 is obtained. The error of the estimated interfacial tension is approximately as large as about 15%. This seems to be acceptable in view of a lack of reliable data in the literature. It is possible furthermore to calculate a kinetic rate constant for any changes that may occur in the colloidal system. The error of this rate constant, however, may be as large as a factor of 10.

Particulate matter deposition on lungs is dependent on aerodynamics of particles physical-chemical characteristics, respiratory tract anatomy, and health status of host object or organ (Hoet et al 2007). …”

Nanotechnology has revolutionized the world through introduction of a unique class of materials and consumer products in many arenas. It has led to production of innovative materials and devices. Despite of their unique advantages and applications in domestic and industrial sectors, use of materials with dimensions in nanometers has raised the issue of safety for workers, consumers, and human environment. Because of their small size and other unique characteristics, nanoparticles have ability to harm human and wildlife by interacting through various mechanisms. We have reviewed the characteristics of nanoparticles which form the basis of their toxicity. This paper also reviews possible routes of exposure of nanoparticles to human body. Dermal contact, inhalation, and ingestion have been discussed in detail. As very limited data is available for long-term human exposures, there is a pressing need to develop the methods which can determine short and long-term effects of nanoparticles on human and environment. We also discuss in brief the strategies which can help to control human exposures to toxic nanoparticles. We have outlined the current status of toxicological studies dealing with nanoparticles, accomplishments, weaknesses, and future challenges.

“…Remote sensing measurements can provide valuable information on hydrological systems by mapping permanent or temporary water bodies and by providing the temporal and spatial variations in the water coverage. Satellite observations are an effective way to detect surface water over large areas with a short revisiting time, supporting operational monitoring and being a rapid as well as effective response to natural disasters, such as floods [17][18][19][20][21].…”

With the increasing availability and diversity of satellite imagery, the multisensor fusion of data can more effectively address the improved monitoring of temporary water bodies. This study supports the attempt to apply well established methods to detect spatial and temporal changes in ephemeral shallow lakes in lowland karst terrain, as well as to improve the understanding concerning the dynamics of water storage and hydrological mechanisms during extreme precipitation events. Based on the joint analysis of Copernicus Sentinel SAR and optical mission data, as well as soil moisture and EO-based rainfall observations over the period of 2015–2020, we demonstrated the control of the karst system on the ephemeral lake appearances in the broader area of Chalkida (Evvia, Greece). A connection between the prolonged and extended water coverage in the ephemeral lakes and flooding in the area is documented. Our EO-supported findings may serve as indicators for flood alerts in future extreme precipitation events, improving responses in cases of emergencies.
