Cadmium binding by fractions of dissolved organic matter and humic substances from municipal solid waste compost.
The agricultural practice of amending soils with composted municipal solid waste (MSW) adds significant amounts of organic matter and trace metals, including Cd. Under these conditions, soluble organic complexes of Cd formed in the compost may be more significant than previously thought, due to Cd bioavailability and mobility in the soil environment. To study the relative importance of differen...

متن کاملDissolved humic substances of vascular plant origin in a coastal marine environment
Bacterial decomposition of vascular plant detritus in coastal wetlands results in the conversion of particulate organic matter to dissolved form and causes the release of humic substances into the bulk dissolved organic carbon (DOC) pool. WC found that 34% of the DOC accumulating during degradation of salt marsh grass (Spartina alternif7oru) from coastal wetlands of the southeastern U.S. fits t...
متن کاملNatural carbon-based dots from humic substances
For the first time, abundant natural carbon-based dots were found and studied in humic substances (HS). Four soluble HS including three humic acids (HA) from different sources and one fulvic acids (FA) were synthetically studied. Investigation results indicate that all the four HS contain large quantities of Carbon-based dots. Carbon-based dots are mainly small-sized graphene oxide nano-sheets ...
