For centuries the sediment of Trieste bay was deposited by the influx of the Soča river, which was mostly affected by changable human actiities, e.g. mining (Idrija, Rabelj) and inflow of local municipal and industrial waste. In this talk we presented the 'history' of sediment composition in sedimentary cores (GT1, GT2, GT3, F1, MK6, V, V3), which were dated using radiocarbon and 210 Pb dating. The following analyses were carried out: Corg., Ntot, Ptot, Porg, Siorg, Sibiog, isotopic 13Corg and 15N, analyses of metals (Fe, Mn, Ti, Cr, Ni, Cu, Zn, Pb, Hg,), PAH and black carbon. Increasing values of Corg, Ntot and Ptot and d15N towards the surface indicate increasing evtrofication. Our data also suggest that recent sediment of Trieste bay is enriched in Cu, Zn, Cd and PAH, and especially Hg, arriving by inflow of the Soča river .

COBISS.SI-ID: 27459623Aquaponics, a combination of fish and crop production, is a form of nutrient recycling and can be established at different urban sides e.g. restaurants with terrace, roofs etc. The nutrient rich water of the aquaculture is recirculated over treatment systems and special kind of hydroponic beds, where nutrients are reused for marketable products like fruits, herbs and vegetables. Aquaponics is a multi-functional integrated technology and has all the benefits of physical water treatment without any use of chemicals, while water circulation and reuse can contribute to water savings. Aquaponics is therefore a promising technology that could contribute to urban food production and towards higher sustainability by reducing the water demands, use of chemicals, and nutrient losses. It can give new economically possibilities for inland farmers in urban areas. Important component in aquaponics are also algae including diatoms, which are involved in treatment processes and nutrient uptake. Understanding the present-day ecological conditions for diatom growth is important also for the reconstruction of past ecological conditions at Mali plac wetland.
