    MOVEMENT PATTERNS OF RIVERINE LITTER (1997)
    Springer
    Water, air & soil pollution 98 (1997), S. 119-139

    ISSN: 1573-2932

    Notizen: Abstract Aspects of litter movement were looked at in a variety of ways. River bank clearances provided valuable information on litter accumulation and movement, showing a distinctive correlation between flood events and litter movement. Introduction of litter outside of channel deposition (diffuse sources) were limited in the study area in South Wales, UK. A rise in litter deposition occurred for some time after flood events, with the main accumulation occurring in the mid-bank zone. As only some litter types have an increased input during flood events e.g. sewage-derived material from combined sewer outfalls (CSO), accumulation of other litter types, e.g. plastic sheeting could be due to their distribution throughout the catchment. A positive correlation between litter stranding and vegetation was found. During high flows, (75.59 cumecs) litter is removed from sites with little restraining vegetation and deposited where stranding potential is high. Smaller items such as feminine hygiene products were more susceptible to stranding than larger plastic sheeting.

    Sources of Riverine Litter: The River Taff, South Wales, UK (1999)
    Springer
    Water, air & soil pollution 112 (1999), S. 197-216 
    Details
    ISSN: 1573-2932
    Schlagwort(e): fly tipping ; riverine litter ; sewage ; sources

    Thema: Energietechnik
    Notizen: Abstract 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 Taff, 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% of all items on the river Taff, large quantities of waste, especially plastic sheeting, originated from fly tipping sites.

    Analysis of the 13C and 1H spectra of mixtures of benzylidene derivatives (1994)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 32 (1994), S. 496-498 
    Details
    ISSN: 0749-1581
    Schlagwort(e): NMR ; 1H NMR ; 13C NMR ; Benzylidene derivatives ; Chemistry ; Analytical Chemistry and Spectroscopy

    Thema: Chemie und Pharmazie
    Notizen: The 1H and 13C NMR spectra of methyl (E)-2,3,-diphenylprop-2-enoate and methyl (E)-2-(2-phenylethenyl) benzoate resulting from the electrocyclic ring opening of benzocyclobutenone starting materials have been assigned. A combination of direct detection 2D NMR techniques, COSY, HETCOR and FLOCK, provided the assignments of the 1H and 13C resonances.
