SOURCES OF RIVERINE LITTER: THE RIVER TAFF, SOUTH WALES, UK

摘要

Riverine litter occupies a spatial and temporal position in any systematic analysis of river systems and is a problem that is increasing in scale. Quantifiable source factors of litter in the river Taft; South Wales, UK, system were found to be mainly two -- sewage inputs through combined sewer overflows (CSO) and fly tipping. The greatest inputs of sewage derived solids were introduced to the river by malfunctioning CSO, the most numerous single component being sanitary towels. Whilst sewage--derived material constituted approximately 23/100 of all items on the river Tat1; large quantities of waste, especially plastic sheeting, originated from fly tipping sites.
