Popis: The bark of neem tree (Azadirachta indica) is used in this study as bio-indicator to monitor heavy metal pollution in Katsina township. Plants can take-up heavy metals from the soil and water via their roots and from the atmosphere via the leaves. The uptake, accumulation and translocation of heavy metals in plants may vary in different species due to anatomical and physiological differences. Barks are sampled from four sites in Katsina township, which include; Katsina Steel Rolling Company Round-about (Site A), Kofar Kwaya Round-about (Site B), Kofar Yandaka Round-about (Site C) and neem tree plantation opposite Nigeria Army Barrack, Natsinta (Site D). The samples are analyzed for Iron, Manganese, Copper, Lead, Cobalt, Chromium, Nickel and Zinc using atomic absorption spectrophotometry (AAS). The results obtained reveal heavy metal levels (µgg– 1) ranging from 52.50 – 196.25 (Fe), 19.50 – 34.25 (Mn), 2.41 – 8.43(Zn)
