Haematological status of wintering great tits (Parus major) along a metal pollution gradient.

摘要: In the long-term biomonitoring of wild populations inhabiting polluted areas, use non-destructive biomarkers as markers condition is very important. We examined possible effects metal pollution on haematological status adult great tits (Parus major) along a well-established gradient near non-ferrous smelter in Belgium. measured blood and feather concentrations assessed (amount red cells, haemoglobin concentration, haematocrit, mean corpuscular volume haemoglobin) during winter at four study sites. Metal feathers indicated that cadmium lead were most important metals under study. Measurements parameters revealed lower from more These significantly negatively correlated with concentration. The amount however, did not differ among Our results indicate affected by may therefore be used successful biomarker for monitoring negative impact exposure wild.
