Ocean Dumping

Eight different tissues taken from crested terns, Sterna bergii, were analysed for the metals cadmium, lead, copper, chromium, manganese, zinc and iron. Birds were taken from a breeding colony before and after the commencement of harbour dredging and ocean dumping operations in nearby Port Kembla Harbour. Levels of chromium and lead were similar in both adult and fledgling terns after dredging began, indicating that chicks acquired these metals from food brought to them by adult birds. However, these metals were found in relatively low concentrations. No conclusive evidence was found of increased assimilation of heavy metals into the trophic structure of communities in waters adjacent to the Five Islands after dredging and ocean dumping operations.

The Individual

Tissues taken from crested terns were analysed for cadmium, lead, copper, chromium, manganese, zinc and iron. The birds were taken from a breeding colony in a non-industrialized region (North Solitary I., NNE. of Coffs Harbour, N.S.W.) and from one near an industrialized region (Big I., Port Kembla, N.S.W.). The birds from the industrialized region did not show any consistent evidence of significant heavy metal contamination when compared to those of the non-industrialized region. The individual tissues were also compared to assess the distribution of the various metals, and the relative degree to which each tissue accumulates the metals. Some accumulation of chromium, copper, manganese, lead and, to a lesser degree, cadmium and zinc was found in the salt glands. The kidneys had a relatively large cadmium content.

Before And After

Investigations on the accumulation of heavy metals (Zn, Cu, Fe, Mn, Co, Pb, Cd and Ni) in water, sediments and fish (Mugil cephalus) using Atomic Absorption Spectrophotometer at Poompuhar coast, lying along the southeast coast of India was studied before and after tsunami. Accumulation of heavy metals was observed in the order of Sediments > Fish > Water. In water, the order was found to be Mn > Fe > Zn > Cu > Ni > Cd > Co > Pb; Mn recorded a maximum of 506.9µ. L-1and Pb recorded a minimum of 0.006µ. L-1. In sediments, the order was Mn > Fe > Cu > Zn > Pb ≈Co ≈Cd ≈ Ni; Mn recorded a maximum of 851.1µg.g-1and a minimum of below detectable levels were found in Pb, Co, Cd and Ni. In fish, the order was found to be Fe > Zn > Mn > Cu > Ni > Co ≈ Pb ≈ Cd; Fe recorded a maximum of 529.13 µg. g-1and a minimum of below detectable levels were found in Pb and Cd.

Abstract Background Heavy metal accumulation in the ecosystem constitutes a potential toxic effect which is hazardous to human health. Increasing environmental pollution has necessitated the use of cattle egrets to evaluate the levels of heavy metal contamination, to establish their use in biomonitoring of heavy metals and to provide data for monitoring pollution in the environment. Results The present study assessed the utilization of Bubulcus ibis in monitoring pollution in five abattoirs, namely Agege, Bariga, Kara, Itire and Idi-Araba, all situated in Lagos State. The concentration of five (5) heavy metals, cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) was determined in the liver, muscle and feather of Bubulcus ibis using the atomic absorption spectrophotometer. The trend of metal accumulation was in the order: Zn > Cu > Pb > Cd > Ni for all the sampled tissues. The mean tissue concentrations of the metals were significantly different (p < 0.05) among the sites. The highest levels of metal concentration were reported in the liver in all the locations. Mean concentration of Cd in Kara (0.003 ± 0.00058) was significantly (p < 0.05) higher than those found at Agege (0.0013 ± 0.00058) and Idi-Araba (0.001 ± 0.001). A significant difference (p < 0.05) was also observed between the mean concentrations of Cu in Bariga (0.01 ± 0.001) and Idi-Araba (0.003 ± 0.001). Conclusion All the studied heavy metals were present in the liver, muscle and feathers of the cattle egrets. The contamination levels were ascertained from the study which indicated that cattle egrets are useful in biomonitoring studies and the generated data will serve as baseline data which could be compared with data from other locations for monitoring heavy metal pollution.
