Dissolved organic matter (DOM) serves as the most active and sensitive component in bay, its biogeochemical characteristics reactivity are affected by properties of terrestrial marine substances significantly. In this study, order to study distribution DOM a semi-closed 34 water samples from 19 stations were collected Zhanjiang Bay analyzed for δ 13 C dissolved inorganic carbon (DIC) fluorescen...

Abstract Three-dimensional excitation–emission matrix fluorescence spectroscopy coupled with parallel factor analysis was adopted to investigate the characteristics of dissolved organic matter (DOM) components in water samples collected from Tuojiang River Basin Chengdu, including its main stream and tributaries. Four DOM that matched three peaks were identified whole river basin tributaries; w...

Ombrotrophic peat bogs have been widely used to evaluate long-term records of atmospheric mercury (Hg) deposition. One of the major aims of these investigations is the estimation of the increase in atmospheric Hg fluxes during the industrial age compared to preindustrial fluxes. Comparability of Hg accumulation rates calculated from density, peat accumulation rates, and Hg concentrations requir...

Plant growth is highly dependent on bacteria, saprophytic, and mycorrhizal fungi which facilitate the cycling and mobilization of nutrients. Over 95% of the sulfur (S) in soil is present in an organic form. Sulfate-esters and sulfonates, the major forms of organo-S in soils, arise through deposition of biological material and are transformed through subsequent humification. Fungi and bacteria r...

Sludge stabilisation and mineralisation during periods of operation between 10 and 21 years were investigated in three different systems receiving sludge from urban wastewater treatment plants situated in Denmark. Samples were taken along the entire profiles, in order to compare the effectiveness of the sludge stabilisation process. Particular attention was given to the stabilisation process oc...

The Nhecolândia is a sub-region of the Brazilian Pantanal wetland, where saline and freshwater lakes coexist in close proximity. Measurements of dissolved organic carbon (DOC) content and analysis of fluorescence excitation-emission matrices (EEM) were conducted in an effort to characterize spatial variability in concentration and source of dissolved organic matter (DOM) and to further understa...

We performed a study of fulvic acids extracted from fresh and aged snow, and from recent and ancient ice in Antarctica. The fresh snow samples were collected in coastal and inland sites to evaluate the influence of the distance from the sea on organic matter transport. Moreover, in a site (Melbourne Mountain) samples were collected at different heights to study the influence of altitude on tran...

The biomass fraction of processed municipal and industrial wastes added to soil can 10 maintain, and in some case improve, the soil’s organic fertility. One of the main constraints in the 11 agricultural use of the sewage sludge is its content of heavy metals. In the long term, soil 12 administration of sewage sludge in agriculture could result in a risk of environmental impact. The 13 aim of t...

Abstract Later prehistoric woodland decline over most parts of Scotland is widely regarded as having been anthropogenic, via a range mechanisms, to create farmland. Climatic causes are seen only have driven the rapid expansion and then terminal Pinus sylvestris around 2000 cal BC . Here we report radiocarbon dated analyses pollen, microscopic charcoal, coprophilous fungal spores peat humificati...

The vermicomposting potential of waste biomass potato crops that are generated at the time harvesting was studied employing Eisenia fetida. experiment carried out in pots, and two treatments were applied during study. In first treatment, only plant (PPB) taken as raw materials; whereas second a mixture PPB with cow dung engaged proportion 5:1. vermicomposted materials showed reduction C/N ratio...
