“…This is in agreement with studies done by Neuhauser et al (1995) and Pizl and Josens (1995) who concluded that copper is only moderately concentrated in earthworm body tissues, because it is a micronutrient and can be regulated.…”

“…The soil fauna of urban greens is particularly exposed to these pollutants. A number of studies have shown that species richness and diversity of earthworms decreased along a gradient of metal pollution (Pižl & Josens, 1995;Nahmani & Lavelle, 2002;Lukkari et al, 2004), and most laboratory ecotoxicity tests or fi eld studies have shown negative effects of metals on survival, growth, feeding activity and reproduction of earthworms (Cikutovic et al 1993;Khalil et al 1996;Kula & Larink, 1998). Several studies have also dealt with heavy metal (HM) effects on enchytraeids in the fi eld, usually in regard of pollution by metallurgical plants.…”

-The effect of soil contamination by polycyclic aromatic hydrocarbons (PAH) and heavy metals on earthworms and enchytraeids was studied in urban parks, in Brno, Czech Republic. In spring and autumn 2007, annelids were collected and soil samples taken in lawns along transects, at three different distances (1, 5 and 30 m) from streets with heavy traffi c. In both seasons, two parks with two transects each were sampled. Earthworms were collected using the electrical octet method. Enchytraeids were extracted by the wet funnel method from soil cores. All collected annelids were counted and identifi ed. Basic chemical parameters and concentrations of 16 PAH, Cd, Cu, Pb, and Zn were analysed from soil from each sampling point. PAH concentrations were rather low, decreasing with the distance from the street in spring but not in autumn. Heavy metal concentrations did not decrease signifi cantly with increasing distance. Annelid densities did not signifi cantly differ between distances, although there was a trend of increase in the number of earthworms with increasing distance. There were no signifi cant correlations between soil content of PAH or heavy metals and earthworm or enchytraeid densities. Earthworm density and biomass were negatively correlated with soil pH; and enchytraeid density was positively correlated with soil phosphorus.Index Terms: Enchytraeidae, Lumbricidae, soil pollution. O efeito de hidrocarbonetos aromáticos policíclicos e metais pesados em anelídeos terrestres de solos urbanosResumo -O efeito da contaminação do solo por hidrocarbonetos aromáticos policíclicos (PAH) e metais pesados em minhocas e enquitreídeos foi estudado em parques urbanos, em Brno, República Tcheca. Na primavera e outono de 2007, os anelídeos foram coletados, e amostras de solo foram retiradas de gramados ao longo de transectos, em três diferentes distâncias (1, 5 e 30 m) de ruas com muito tráfego. Nas duas estações, foram amostrados dois parques com dois transectos cada um. As minhocas com uso do método do octeto elétrico, e os enquitreídeos foram extraídos das amostras de solo pelo método do funil úmido. Todos os anelídeos coletados foram contados e identifi cados. Parâmetros químicos básicos e concentrações de 16 PAHs, Cd, Cu, Pb e Zn, de cada ponto de amostragem, foram analisados. As concentrações de PAH foram relativamente baixas, e decresceram na primavera, mas não no outono, com a distância da rua. As concentrações de metais pesados não diminuíram signifi cativamente com o aumento da distância. As densidades de anelídeos não diferiram signifi cativamente entre as distâncias, mas houve tendência de aumento no número de minhocas, com o aumento da distância. Não houve correlação signifi cativa entre o conteúdo de PAH ou metais pesados do solo com as densidades de minhocas e enquitreídeos. A densidade e a biomassa das minhocas foram negativamente correlacionadas ao pH do solo; e a densidade de enquitreídeos foi positivamente correlacionada ao conteúdo de fósforo no solo.

“…Cette observation pourrait s'expliquer par le fait que la survie des vers de terre soit négativement impactée par les fortes concentrations de substances polluantes mesurées à proximité de la chaussée. Ce résultat est en adéquation avec ceux de plusieurs auteurs (Pižl & Josens, 1995 ;Spurgeon et al, 2000 ;Nahmani et al, 2003 ;Zheng et al, 2008) qui ont montré que les ETM et les HAP réduisent la densité des vers de terre, leur croissance pondérale et leur fertilité. Par ailleurs, l'utilisation du mécanisme d'évitement des poches de pollution du sol pourrait également expliquer cette réduction des densités de vers de terre par monolithe le long des transects d'échantillonnage.…”
