 as tools for use in monitoring and environmental impact assessment, such biomarkers being indicative of contaminant exposure and/or impact. This study was designed to determine the concentration of Cadmium (Cd), Chromium (Cr), and Nickel (Ni) in whole blood of free ranging white Fulani cattle (<i>Bos primigenius indicus</i>) and red Sokoto goats (<i>Capra aegagrus hircus</i>) as biomarker to provide sensitive indexes, or early warning signals of potential degradation of Zaria ecological geochemical environment as well as possible health risk posed by the consumption of this major source of animal protein from the area. The assessment was carried out by Atomic Absorption Spectrophotometry using Shimadzu Atomic Absorption Spectrophotometer (model AA-6800, Japan) after wet digestion. Results indicates that the blood cadmium, chromium and nickel levels ranged from 0.321 mg/l to 1.421 mg/l, 2.171 to 4.856 mg/l and 3.158- 7.135 respectively for <i>Bos primigenius indicus</i> and from 0.321 to 1.421 mg/l, 2.171 to 4.856 mg/l and 3.158 to 7.135mg/l respectively for <i>Capra aegagrus hircus</i>. Since the observed levels of the metals were significantly (p < 0.05) higher than the control and the maximum permissible limits, pollution of the environment where the animals feed could be inferred. Consumption of edible tissues of these animals could pose serious toxicological risk. Implication of findings to public health is fully discussed.&picture=http://www.aascit.org/aascit/decorators/img/journal/904.jpg)

Recent years have seen the development of biological measurements (biomarkers) as tools for use in monitoring and environmental impact assessment, such biomarkers being indicative of contaminant exposure and/or impact. This study was designed to determine the concentration of Cadmium (Cd), Chromium (Cr), and Nickel (Ni) in whole blood of free ranging white Fulani cattle (Bos primigenius indicus) and red Sokoto goats (Capra aegagrus hircus) as biomarker to provide sensitive indexes, or early warning signals of potential degradation of Zaria ecological geochemical environment as well as possible health risk posed by the consumption of this major source of animal protein from the area. The assessment was carried out by Atomic Absorption Spectrophotometry using Shimadzu Atomic Absorption Spectrophotometer (model AA-6800, Japan) after wet digestion. Results indicates that the blood cadmium, chromium and nickel levels ranged from 0.321 mg/l to 1.421 mg/l, 2.171 to 4.856 mg/l and 3.158- 7.135 respectively for Bos primigenius indicus and from 0.321 to 1.421 mg/l, 2.171 to 4.856 mg/l and 3.158 to 7.135mg/l respectively for Capra aegagrus hircus. Since the observed levels of the metals were significantly (p < 0.05) higher than the control and the maximum permissible limits, pollution of the environment where the animals feed could be inferred. Consumption of edible tissues of these animals could pose serious toxicological risk. Implication of findings to public health is fully discussed.
