Soil profiles were collected at a depth of 30 cm in ditch wetlands (DWs), riverine wetlands (RiWs) and reclaimed wetlands (ReWs) along a 100-year chronosequence of reclamation in the Pearl River Delta. In total, 16 OCPs were measured to investigate the effects of wetland reclamation and reclamation history on OCP levels. Our results showed that average ∑DDTs, HCB, MXC, and ∑OCPs were higher in ...

The temporal distribution of organochlorine pesticides (OCPs) was examined in the (210)Pb dated sediment core from the Beibu Gulf, South China Sea. The total OCPs concentrations were in the range of 0.93-26.6 ng g(-1) dry weight. Dichlorodiphenyltrichloroethanes (DDTs) (0.17-24.8 ng g(-1)), Hexachlorocyclohexanes (HCHs) (0.04-0.51 ng g(-1)), Chlordane related compounds (CHLs) (0.22-1.72 ng g(-1...

Cele Oasis on the southern edge of Tarim Basin was used to investigate the impact of human activity on the soil environment of the oasis–desert ecotone during the oasis expansion process. Since farmland is extending into the oasis–desert ecotone during oasis expansion, reclaimed farmland and control plots within the ecotone were investigated. The variations in soil moisture, soil nutrients and ...

Land disturbance during mining results in loss of soil organic carbon (SOC). Reclamation of minelands can lead to recuperation and sequestration of SOC. The SOC thus accumulated, not only replenishes SOC losses but may also offset additional carbon di-oxide (CO2) emission. The assessment of the above was done on a chronosequence of reclaimed minesoils comprising pasture with topsoil application...

Small scale mining activities which involve surface mining is an acceptable means of mineral exploitation in Ghana but has serious environmental consequences. Although a number of laws and research papers have been written on restoration after a piece of land has been mined, not much detail is provided on the actual processes involved. This review paper attempts a look at the process of restora...
