Enormous amounts of seawater are desalted everyday worldwide. The total world production of fresh water from the sea is about 2621 mgd (9.92 million m(3) day(-1) 1985 figures). Desalting processes are normally associated with the rejection of high concentration waste brine from the plant itself or from the pretreatment units as well as during the cleaning period. In thermal processes, mainly mu...

The effects of five towns on river water pollution were examined along the Łyna River (southern watershed of the Baltic Sea, northern Poland). The relationships among the spatially derived indicators of urbanization, environmental variables, and physico-chemical and microbiological data (heterotrophic plate count at 22 and 37 °C, and fecal coli) obtained from longitudinal river profiling have b...

Polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) are two classes of micropollutants intensively monitored and regulated due to their toxicity, persistency and wide diffusion. Their concentrations have been investigated in sea-microlayer (SML) and sub-surface water (SSW) samples collected at two sites of the Venice Lagoon, a fragile ecosystem highly influenced by indu...

Despite management of point sources, heavy metals today remain at an elevated level in the urban environment, with diffuse sources dominating the emissions. In order to manage these pollutants, it is necessary to understand the coupling between the urban sources of heavy metals and their monitored, environmental levels, for example in aquatic sediments. In this work, we suggest a simple approac...

The level of aquatic contamination in ports and other aquatic area is increasing unceasingly. The level of security of our sea region and other aquatic area can also be increase with the use of innovative technologies. These are the main driving force behind efforts to make more advance system for WATER WORLD. In this paper an innovative approach to robotic education is described by giving the ...

Distribution of the sixteen polycyclic aromatic hydrocarbons (PAHs) indicated from USEPA as priority pollutants was studied in surface sediments of two coastal areas of the Adriatic Sea. PAHs were recovered from the sediments by solvent extraction and then analyzed by means of gas chromatography-mass spectrometry. Total concentrations of the analytes in the range 24.1-501.1 ng/g were detected. ...

The eleven nuclear power plants in operation, under construction and a well-planned plant in the east coast of China generally use seawater for reactor cooling. In this study, an oceanic dispersion assessment system based on a database of tidal harmonic constants is developed. This system can calculate the tidal current without a large computational cost, and it is possible to calculate real-ti...

A number of experiments all over the world have proven that satellite borne SAR images constitute a valuable tool to monitor oceanic environment, preventing it from overexploitation or pollution matters and it can also help to evaluate the full implications of natural or man made hazards. In fact, thanks to their capability to cover large areas, in all weather conditions, during the day as well...

The term “sea waste” generally refers to any solid, liquid, or gaseous material substance that is discarded, disposed of, abandoned in the ocean, sea, other body of salty water, such as a lagoon, etc. This includes waste generated by human activities on land makes its way into well ships and vessels at sea. Examples sea include plastic debris, chemicals toxic substances, oil spills, sewage, for...
