a study of the atmospheric particulate size distribution of total suspended particulate matter(tspm) and associated heavy metals concentrations has been carried out for the urban part of sarajevo city,bosnia and herzegovina. urban particles (n=150) were collected using a high volume air sampler equippedwith a 6-stage impactor. apart from fe which has been determined by flame atomic absorption s...

Suspended solids or sediments can be pollutants in rivers, but they are also an important component of lotic food webs. Suspended sediment data for rivers were obtained from a United States-wide water quality database for 622 stations. Data for particulate nitrogen, suspended carbon, discharge, watershed area, land use, and population were also used. Stations were classified by United States En...

Abstract. Amino acids (AAs) mainly bound in proteins are major constituents of living biomass and non-living organic material the oceanic particulate dissolved matter pool. Uptake cycling by heterotrophic organisms lead to characteristic changes AA composition so that AA-based biogeochemical indicators often used elucidate processes degradation. We analyzed a large sample set collected various ...

The surface layer of the urban atmosphere significantly affects human health. Its quality depends on level air pollution. aim was to determine size distribution suspended particulate matters (SPMs) in atmospheric Vladivostok city and assess response blood immune metabolic parameters population with bronchopulmonary pathology. Sampling SPMs conducted continental zone a high technogenic pollution...

Vertical profiles of suspended particulate trace metals were measured in the Sargasso Sea near Bermuda and in the California Current, northwest Pacific. Using a new in situ pump, sufficiently large samples of particulate matter (order 10mg) were collected to allow measurement of a suite of trace metals as well as major component elements, using several different leaching techniques on separate ...

The suspended particle assemblage in complex coastal waters is a mixture of living phytoplankton, other autochthonous matter, and materials of terrestrial origin. The characterization of suspended particles is important for understanding regional primary productivity and rates of carbon sequestration, the fate of anthropogenic materials released to the coastal environment, as well as its effect...

Hong Kong International Airport (HKIA) is an important sea airdrome in China. The aim of this study to evaluate the impacts reclamation on water quality Northwestern Bay (NWBHK). In all, 117 Landsat 5 TM and 44 8 OLI images were preprocessed matched with marine data 18 situ monitoring points, acquiring 458 119 sets data, respectively. This adopted BPNN Machine Learning methods establish retriev...

Satellite imaging, a form of remote sensing, can be used to analyse water quality, which must monitored for proper and sustainable environmental management. This paper studies the effect sea traffic reduction in Alboran Sea (Spain), analysing changes quality before (from February 3rd, 2020) during (until June 22nd, confinement period. was an unprecedented event modern times brought interesting ...
