“…Then, these samples were filtered using 0.45-um membrane filters. All the standard precautions recommended by Kremling (1983) to reduce risks of sample contamination were followed during collection and treatment of samples. Solvent extraction was utilized using ammonium pyrrolidinedi-thiocarbamate (APDC) and methyl isobutyl ketone (MIBK).…”

Background: Burullus Lake has received a great attention because of its environmental and economic importance for connecting with the Mediterranean Sea through El Boughaz opening. Some of the chemical analyses were performed to study the potential environmental risk of Burullus Lake. The present study explores the potentiality of environmental risk of Fe, Mn, Co, Ni, Cr, Cd, Pb, Zn, and Cu for detecting most vulnerable areas to water and sediment pollution at Burullus Lake during different three periods: 2010, 2012, and 2015. The concentrations of DO, BOD, COD, and TDS during three periods 2010, 2012, and 2015 were higher than the WHO limits for the protection of fish and other aquatic life in Burullus lakes. Results: The mean concentrations of heavy metals in Burullus bottom sediments in 2010

“…Immediately after recovery the GO-FLO bottles were transferred into a clean container (ISO 5, class 100, GEOMAR). In line filtration (0.2 lm) was conducted by applying overpressure of 0.2 bar (N 2 -grade 5.5) to the GO-FLO bottle and filtering the sample into previously acid cleaned PTFE bottles (Kremling et al, 2007). Two different filter types were applied, cellulose acetate membrane filter capsules (Sartobran Ò P, Sartorius Stedim Biotech S.A.) and track-etched polycarbonate membrane disk filters (Nucleporee, 47 mm, Whatman).…”

“…Coastal water samples were collected from the ten stations using Nansen bottles at 2 m depth, and then, stored in acid-washed polyethylene bottles until analysis. All the precautions recommended by [22] to minimise risks of sample contamination were followed during collection and treatment of samples. Dissolved heavy metals were determined according to [23], as modified by [24].…”

In an attempt to evaluate the environmental quality of Marsa-Matrouh city which covered the most famous beaches in Egypt, an environmental risk assessment was performed, including a screening level ecological risk assessment. The aim of this work was to determine which metals could possibly pose toxic adverse ecological effects to marine organisms and to determine whether hot spots exist or not. To fulfill the goals of study, surfacial sediment and water samples were collected from ten different locations covering MarsaMatrouh city during four seasons (2010)(2011). The average concentrations of Cd, Cu, Fe, Ni, Pb and Zn were 2. 381 ± 3.389, 9.307 ± 14.159, 68.969 ± 9.397, 2.642 ± 1.004, 16.712 ± 8.469, 31.168 ± 15.322 μg/l in water and 0.755 ± 0.240, 5.363 ± 1.581, 962.131 ± 975.084, 3.972 ± 2.180, 15.210 ± 4.434 and 24.608 ± 7.706 μg/g dry weight in sediment respectively. The concentrations of the investigated six metals in water were within the acceptable limits except for two stations (Cleopatra and El-Obayed) which exhibited higher values than the permissible level of Cd during autumn 2010. Metal pollution assessment for both water and sediment was studied. Heavy metal pollution index indicates that water is not critically polluted with respect to the investigated metals. For sediment samples, threshold effect concentrations (TEC HQ) were lower than 1 except for Cd which showed higher value than 1, indicating the possibility of occurrence of toxic adverse ecological effects to benthic organisms for Cd, while rare adverse ecological effects are expected to occur with respect to Cu, Ni, Pb and Zn.
