Recent publications reporting dissolved trace metal data have highlighted the susceptibility of such determinations to contamination during sampling and analysis. Results from recent surveys using stringent anti-contamination procedures have suggested that much of the earlier data has been affected by contamination. New surveys are desirable, therefore, particularly in areas which are known to receive considerable burdens of trace metal pollution.

Host Parasite

Studies on host-parasite systems as bioindicators for monitoring trace metal pollution in marine environments are still scarce. Here, 11, 14 and 17 infrapopulations of Gyliauchen volubilis (Trematoda: Digenea), Procamallanus elatensis (Nematoda) and Sclerocollum rubrimaris (Acanthocephala), respectively, were collected from the fish Siganus rivulatus (Siganidae) in the Red Sea, from a chronically polluted small bay at Sharm El-Sheikh, South Sinai, Egypt. Water and sediment samples from the bay, tissue samples (intestines, liver, and muscle) from each fish, and samples from each parasite were taken for heavy metal analyses of cadmium and lead. Cadmium concentrations in intestines, liver and muscle of non-infected and infected fishes were much lower than those of lead, and both metal concentrations decreased in the order: liver > intestines > muscle. Cadmium and lead concentrations in the tissues of fishes infected with G. volubilis or P. elatensis were slightly lower than those in non-infected ones, while in the tissues of fishes infected with Sc. rubrimaris, they were much lower. Low concentrations of cadmium and lead in G. volubilis and P. elatensis are associated with their limited ability or capacity to accumulate trace metals. Therefore, bioconcentration factors corresponding to these species were relatively low, and both are herein considered as weak bioindicators. By contrast, high concentrations of cadmium and lead in S. rubrimaris are associated with its high ability to accumulate trace metals. Of the present three host–parasite systems, only the Siganus rivulatus–Sclerocollum rubrimaris system seems to be promising for biomonitoring of metal pollution in the Red Sea.

An understanding of trace metal pollution due to reclamation activities around Yancheng National Nature Reserve is important for the utilisation and management of the reserve and surrounding coastal and marine areas. In the present study, we evaluated the current state of Cu, Cd, Pb and Zn pollution (total concentrations and ecological risk), their potential hazard (availability index and desorption rate) and soil properties (cation exchange capacity, iron and manganese oxide content, soil organic matter, salinity and pH) in different land use types around this nature reserve. Although the current state of trace metal pollution was not severe, the potential hazards of these trace metals should not be ignored, especially for Cd because of its significantly higher availability index values in farmlands and aquaculture ponds than in natural habitats (by 33 and 32% of the total amount of Cd respectively). Thus, strict monitoring and environmentally responsible land reclamation management practices should be considered for these coastal areas.

Abstract The accumulation of trace metals in vegetable field soils is of expanding worry because of the potential health hazards and its detrimental effects on soil ecosystems. To investigate the state of trace metal pollution in vegetable field soils, 60 surface soil samples were collected from vegetable fields across the Eastern Nile Delta region, Egypt. The results explained that the concentrations of Cu, Mn and Ni were lesser than their corresponding background values, while the concentrations of Cd, Co, Pb and Zn were exceed their background values. The pollution indices showed that the study soil experienced low to moderate contamination, and the Cd and Cr contamination was serious. The hazard index values of nine trace metals signified that there no adverse non-carcinogenic risk for adults and children. The carcinogenic risk of Cd, Co, Ni and Pb for both age groups was within the acceptable limits, while Cr had critical carcinogenic hazard to children. Overall, the quality of studied soils is relative safety, although some samples impose serious pollution problems by Cd and Cr. Thus, properly monitor trace metals and soil management action should be applied to reduce further soil pollution in vegetable fields in the Eastern Nile Delta.
