The acceleration of urbanization and rapid development of economy led to making surface water pollution problem becoming more critical. Water treatment technologies can be generally classified as insitu or ex-situ. In this paper, a comprehensive review describing the latest surface water remediation developments and technologies that can be suitable for in-situ applications. The review covers t...
Physiological integration can enhance the performance of clonal plants in aquatic and terrestrial heterogeneous habitats and associated ecotones. Similar to nutrients, pollutants may be transported among connected ramets via physiological integration. Few studies have examined the expansion of amphibious clonal plants from terrestrial to aquatic environments, particularly when the local water s...
Biochemical markers are measurable responses to the exposure of an organism to xenobiotics as well as very suitable biosensors of aquatic pollutants. Aquatic pollution can easily be detected through biomarkers, as enzymes provide one of the most reliable means of assessing the degree of exposure of animals to pollutants. Some of the biochemical alteration occurring in the body gives the first i...
In this paper we present an expert system that monitors sea water quality and pollution in Northern Greece, through a sensor network called "Andromeda". The expert system monitors sensor data collected by Local Monitoring Stations and reasons about the current level of water suitability for various aquatic uses, such as swimming and piscicultures. The aim of the expert system is to help the aut...
This investigation was aimed to evaluate water pollution with heavy metals using three biomarkers, as well as the study of the aquatic insects-seasons interaction. Three species of aquatic insects collected from El-Mansouriya stream (Dakahlia, Egypt), during the different seasons from spring 2014 to winter 2015. Water samples, sediments and whole body of the three aquatic insects were analyzed ...
Sound travels very efficiently underwater, so the potential area impacted can be thousands of square kilometers or more. Anthropogenic activities such as commercial shipping, recreational activities, drilling, seismic exploration or energy production (hydroelectric power plants), have made underwater noise pollution an increasing and perhaps dominant factor in the aquatic environment. Nowadays,...
Agriculture and urban activities are major sources of phosphorus and nitrogen to aquatic ecosystems. Atmospheric deposition further contributes as a source of N. These nonpoint inputs of nutrients are difficult to measure and regulate because they derive from activities dispersed over wide areas of land and are variable in time due to effects of weather. In aquatic ecosystems, these nutrients c...
