Patos Lagoon is the largest choked coastal lagoon in world (250 km long, 40 wide and mean depth of 5 m), with banks formed by sand predominantly muddy bottom. The circulation mainly driven wind river flow, a minor contribution local microtidal regime. This one most studied water bodies Brazil. suspended particulate matter (SPM) data compendium consists over four decades (1978–2019) SPM gathered...
The circulation and transport of suspended particulate matter in the Caravelas Estuary are assessed. Nearlysynoptic hourly hydrographic, current (ADCP velocity and volume transport) and suspended particulate matter data were collected during a full semidiurnal spring tide, on the two transects Boca do Tomba and Barra Velha and on longitudinal sections at low and high tide. On the first transect...
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...
Air pollutants of concern include traffic-related air pollution, including particulate matter in respirable coarse and fine size fractions. There are no critical studies to date into associations between knowledge, awareness, and attitudes in using proper respiratory masks and prevalence of respiratory symptoms among urban street vendors in Thailand. In this study, we estimated adverse respirat...
Mining activities mainly deal with the excavation of raw material from earth’s crust. The sources of particulate matter (PM) emission in opencast coal mines include blasting and drilling operations, coal handling plant operation, loading and transport of overburden and coal by shovel-dumper combination, crushing, conveying and handling of overburden by draglines, and vehicular emission from unp...
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...
