“…Similar work was done by El Nemer [36] on sediments from Lake Burullus (MPI = 162.5) and comparing with those done it was found that in the current work the MPI is less than calculated by [36]. The MPI was calculated for the studied elements from different work and MPI for Upper Continental Crust UCC content of the 6 elements as shown in Table 7.…”

“…It could be explained by existence of the studied area in the west of Nile Delta near to Sadat City. MPI has a significance value from the work done in [36] which is higher three times than the MPI in the present work because of Lake of Burullus is a closed aquatic system and the disposal rate of waste from industry and sewage is high. …”

“…The plotted spatial distribution of heavy metals in soil showed a noticeable increase of their content upwards the direction of the Mediterranean Sea. MPI parameter was calculated to study the overall content of heavy metals which ranged from 32 to 78 with an average value of 55 ±15, and it is less than that calculated by El Nemer [36] for the sediments from Lake Burullus (MPI = 162.5). It was shown that As moderately enriched in the study area: 5 < EF > 10.…”

Assessment of the environmental impact of El Sadat City, a Cairo satellite, known for its clustered enterprises, on the neighbourhood water supply El Manashi Tawfikia Canal was undertaken through soil analysis. A total of 20 agricultural soil samples were collected along the El Manashi Tawfikia Canal. Neutron activation analysis was implemented to determine heavy metal contents of such elements as As, Ba, Co, Cr, Ni, and Zn. Multivariate statistical analysis was applied to the results obtained. The metal pollution index and enrichment factor were calculated. It was shown that the content of toxic heavy metals in soil samples does not exceed the worldwide-published values, except arsenic which considerably exceeds normalized to the content of the same element in the Upper Continental Crust. The metal pollution index is high compared with the calculated ones for similar soil samples from the Nile Delta, and the enrichment factor varied from moderate to high enrichment (5 < EF > 10).

“…An aliquot of 0.5 g of dry sediment (mud or sand) was shaken with 1N HCl (40 ml) at room temperature for two hours (El Nemr, 2003;Villares et al, 2003). The suspension was filtered on the nuclepore 0.4 μm polycarbonate filters, previously treated with 6M HCl and Ultra-pure water, then with 1M CH 3 COONH 4 and finally with 100 ml ultra-pure water (triplicate extractions were made for each sample).…”

“…Analysis of the leachable (labile) metal fraction of the sediment may be more useful, in terms of discovering its biological significance and the new inputs, than analysis of the total metal fraction (Lacerda et al, 1992;Puente et al, 1996;El Nemr, 2003). However, sediment analysis is more indicative than water analysis for evaluating the degree of contamination in the aquatic medium.…”

The concentrations of nine heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pd and Zn) in the labile and total fractions of muddy and sandy sediment samples collected from twelve sites in Suez Gulf during April 1999 were studied to evaluate the pollution status of the Suez Gulf. The enrichment factors (EF) for each element were calculated. There are extremely high concentrations of Cd, Ni, Pb and slightly concentration of Cr and Cu in both muddy and sandy sediments. The concentration of Zn was moderately high and can be considered as seriously contaminate Metal pollution index (MPI) shows high values ranged between 46 to 156 and 40 to 232 for both sandy and muddy sediments, respectively. Concentrations of heavy metals were normalized against iron for total fraction in both of sandy and muddy sediments. Principal component analysis (PCA) was studied on the data matrix obtained and represented three-factor model explaining 92.22% for labile and 88.82% for total fractions of muddy sediment. The main source of contamination is the offshore oil fields and industrial wastes. This is largely a result of ineffective and inefficient operation equipment, illegal discharge of dirty ballast water from tankers and lack of supervision and prosecution of offenders.

Acid leachable trace metals in sediment cores from Sunderban Mangrove Wetland, India: an approach towards regular monitoring

et al. 2009

The paper presents the first document to identify the enrichment pattern of acid leachable trace metals (ALTMs) such as Fe, Mn, Cr, Cu, Ni, Pb, Cd, Co, Mo, Ag, As and Ba and their relationship with sediment quality parameters (pH, organic carbon, carbonates and texture) in core sediments (<63 microm particle size) from Indian Sunderban mangrove wetland, formed at the estuarine phase of the river Hugli (Ganges). Textural analysis reveals an overall predominance of mud. The results indicate that the change in pH values causes coagulation and precipitation of ALTMs. Fe and Mn have fairly close distribution patterns of enrichment in surface layers which might be ascribed to early diagnetic processes. The most prominent feature of ALTMs is the enrichment of Fe, Mn, Cr, Cu, Ni, Pb, and Ba in the surface-subsurface layers in the sediment cores, which is mainly attributed to the intense industrial and agricultural activities as well as drainage of untreated domestic sewage to this coastal region. The ALTMs also indicate their association with organic carbon and Fe-Mn oxyhydroxides. The enrichment is well--supported by the correlation, grouping and clustering of ALTMs in statistical analyses. Anthropogenic Factor values indicated ALTMs enrichment for all trace metals due to intense anthropogenic activities. Overall higher values of ALTMs in sediments in comparison to other Indian coastal regions indicate that they are mainly due to the uncontrolled anthropogenic activities in this mangrove estuarine complex. Statistical analyses suggest that five ALTMs (Cu, Pb, As, Mo, Ba) are attached to the organic particles and the clustering of elements separately also indicates that they are from external source. The result of the present study suggests the need for a regular monitoring program which will help to improve the quality of this potential wetland.
