This work demonstrates the efficiency of using linear statistical modelling for estimation of concentrations of various substances in lake water using remotely sensed multiand hyperspectral images together with extensive field measurements collected over Lake Erken in Sweden. A linear relationship was assumed between image data and the corresponding field measurements, and the transformation co...

Sediment, suspended matter, river water and ground water samples were collected at twelve sites in the drainage valley of the Nile River, around Sohag (Central Egypt) and close to the Aswan High Dam. Elemental composition of the river water (27 elements), ground water (eight elements), suspended matter (12 elements) and sediments (12 elements) was studied. Aswan High Dam construction, agricultu...

The hydrological conditions, suspended matter concentrations and vertical particulate matter flux were measured as the River Vistula flood wave (maximum discharge) was flowing into the southern part of the Gulf of Gdańsk on 26 May 2010. Extending offshore for several tens of kilometres, the river plume was well stratified, with the upper layer flowing away from the shore and the near-bottom wat...

polycyclic aromatic hydrocarbons (pahs) have been determined in the atmosphere of isfahan, iran. airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). extraction of pahs from airborne particulate matter has been performed using sfe system and the relationship between the extraction temperature and the recovery of pahs from airborne particulates is inve...

This study aimed to determine the variability of carbon and nitrogen elemental content, stoichiometry and diet proportions of invertebrates in two sub-tropical estuaries in South Africa experiencing seasonal changes in rainfall and river inflow. The elemental ratios and stable isotopes of abiotic sources, zooplankton and macrozoobenthos taxa were analyzed over a dry/wet seasonal cycle. Nutrient...
