Recreational Parks (RP) of the city Poznan were investigated in October 2009 in order to evaluate contamination state of their soils by lead and cadmium. From the Recreational Park Marcinkowski – RPM, Recreational Park Solacki – RPS, Recreational Park Wodziczko – RPW and Recreational Park Piatkowo – RPP the soil samples were collected at two depths, ie 0–10 and 10–20 cm, in the quantity of 36, 52, 32 and 34, respectively. The total content of Pb and Cd was determined in these samples, as well as some their selected physical and chemical properties. Detailed assessment of the soil contamination state was undertaken on the basis of different indices such as geochemical accumulation index (Igeo), factor (C f i ) and degree (Cdeg) of contamination. The evaluation of soils made by applying Pb-Igeo has shown that parks may be ranged as follows: RP Piatkowo < RP Solacki < RP Wodziczko < RP Marcinkowski. The concern and threat related to the impact of Pb on humans requires more restrictive limits of content, hence geochemical background (GB) values as reported by Czarnowska [20] may be considered as more adapted for protecting from potential health hazards. In the case of cadmium, the Cd-Igeo based contamination assessment allowed to organize parks accordingly: RP Piatkowo < RP Marcinkowski < RP Solacki < RP Wodziczko. Cadmium contribution in the overall contamination (Cdeg) changed as did the Cd-Igeo indices. This was mostly reflected in the RPs Wodziczko and Solacki and intermediately in the RP Marcinkowski. On the basis of the performed geochemical evaluation of soil Recreational Park Piatkowo is the sole to be classified as free from Pb and Cd contamination threat.
Rekreacyjne Parki (RP) miasta Poznań zbadano w październiku 2009 r. w celu oceny stanu zanieczyszczenia ich gleb ołowiem i kadmem. Z Parku Marcinkowskiego - RPM, Parku Sołackiego - RPS, Parku Wodziczki - RPW i Parku Piątkowo - RPP pobrano próbki gleby z dwóch głębokości (0-10 10-20 cm) w ilości odpowiednio: 36, 32, 52 i 34. Oznaczono całkowitą zawartość Pb i Cd oraz wybrane właściwości fizyczne i chemiczne tych próbek gleby. Szczegółową ocenę stanu zanieczyszczenia gleb rzeprowadzono na podstawie różnych wskaźników, takich jak: geochemiczny indeks akumulacji (Igeo) oraz spółczynnik (C współczynnik ) i stopień (Cdeg) zanieczyszczenia. - Źródło:
