Abstract. Riverine transport of particulate organic carbon (POC) associated with terrigenous solids to the ocean has an important role in global cycle. To advance our understanding source, transport, and fate fluvial POC from regional scales, databases riverine are needed, including elemental isotope composition data contrasted river basins terms geomorphology, lithology, climate, anthropogenic...

Tianjin urban/industrial complex is highly polluted by some persistent organic pollutants. In this study, the levels of 16 priority polycyclic aromatic hydrocarbons (PAHs) were tested in sediment, water, and suspended particulate matter (SPM) samples in 10 rivers in Tianjin. The total concentration of 16 PAHs varied from 0.787 to 1943 microg/g dry weight in sediment, from 45.81 to 1272 ng/L in ...

The occurrence of microcystins (MC) during aquatic blooms of cyanobacteria in eutrophicated freshwater body has increasingly become an environmental and health concern worldwide. An experimental study was conducted to investigate the adsorption of two common variants of microcystins, MCLR and MCLW, onto SPM at different pH values. The results showed that most microcystins spiked into an SPM sol...

Fireworks display during festive celebrations can cause acute short term air pollution. Deepawali –the festival of light– is celebrated in India, every year during October or November with great fireworks display. Concentration of air pollutants such as SPM (suspended particulate matter), PM 10 , PM 2.5 , SO 2 and NO 2 were monitored for six consecutive days during Deepawali in Salkia, a densel...

Highly mutagenic compounds such as some PAHs have been identified in surface waters and sediments of the Seine river estuary. Suspended particulate matter (SPM) represents a dynamic medium that may contribute to the exposure of aquatic organisms to toxic compounds in the water column of the estuary. In order to investigate major sources of mutagenic contaminants along the estuary, water samples...

The understanding of the sedimentary dynamics is important in characterization impacts caused by dredging and this knowledge becomes decisive for their discernment. aim article was to analyze plume dispersion sediments Port Maceió. analyzes were carried out three sampling campaigns, before, during after port works, which collection points discard areas plotted. suspended particulate material (S...

Abstract The aim of this paper is the presentation current state-of-the-art about determination polycyclic aromatic hydrocarbons (PAHs) and their oxidized forms originating from Suspended Particulate Matter (SPM) samples. influence SPM on health twofold. SPM, as composed small particles, dangerous for respiratory system. Additionally, a carrier many hazardous compounds, particularly PAHs. Recen...

Airborne suspended particulate matter (SPM) is a serious worldwide concern since it is linked with adverse health effects. Several epidemiological studies have been made across the world revealing the association of SPM in air with acute and chronic respiratory disorders, lung cancer, morbidity and mortality. Odds ratio estimated by several studies of the dose–response relationship for particul...
