This area has an important strategic location in future, the Iraqi Government intending to establish large engineering projects such as a big Basrah port. Sediment samples have been taken at a depth of 1.25 m to study the physical, chemical, and engineering properties of this region’s sediment. The investigation results reveal that its average high natural moisture was 37.5 %, Liquid Limit LL 45.5 %, Plastic Limit PL 26.5 %, Plasticity Index PI 19%. Hence, these sediments show high clay percentages (85-65%). It can be classified as Silty Clay sediments with low plasticity. Engineering tests resulted in average Compression Strength of 206 kN/m2, Max. dry density 1.63 g/cm3 while consolidation coefficient 0.15 m2/year, consolidation index (0.28) with initial consolidation 35.5 kN/m2, and swelling index 0.071.

Grain size distribution and statistical parameters revealed that the deposits are mainly composed of silt and clay with very small portion of sand, and have mud type texture. There is a tendency of increasing in silt percentage from Sarraji toward Abul Khasib area and decreasing in clay percentage with depth. Generally, the sediments are poorly sorted, coarse to strongly coarse skewed and platykurtic to very platykurtic deposited in quiet environment and low energy conditions. Chemical analysis showed that all samples have high concentration in SiO2 and CaO in comparison with Al2O3, Fe2O3, MgO, SO3, K2O and Na2O. These results are generally in agreement with the mineral composition. Mineralogically, the sediments understudy consists of quartz, feldspar, calcite, dolomite and gypsum. Clay minerals assemblages are: chlorite-montmorillonite mixed layers 37%, Illite 20%, Chlorite 18%, Kaolinite 14% and Palygorskite 11%. Increasing in Ch-Mont. percentage could be an evidence of high intensity of diagenetic alteration processes in depositional environment. The clay mineral assemblages proved that the recent sediments of the studied samples were derived from the basic igneous and metamorphic rocks, while acidic igneous and sedimentary rocks sources are less important. The deposition environment of these minerals may be characterized by an arid to semi-arid climate in the source area.","PeriodicalId":259361,"journal":{"name":"Mesopotamian Journal of Marine Sciences","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131240925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On an average, the earthworm had lower protein content (46.57 ± 0.97%) than fishmeal had (54.97 ± 7.49 %). On the other hand, the mean lipid content (8.03 ± 0.44 %) in this earthworm was found to be higher compared to fishmeal (7.97 ± 1.60 %). The average ash content in the earthworm and fishmeal were 24.26 ± 0.68 % and 24.13 ± 8.44 %, respectively. The results of the present study indicate that this earthworm species had almost similar nutritional values to the fishmeal, and thus would be a potential source of animal protein in supplementing fishmeal.

To evaluate such kind of contamination, we undertook a research programme to analyze the concentrations of zinc, copper, lead and cadmium in muscle tissue of five commonly edible shrimp species, namely Penaeus monodon, Penaeus indicus, Penaeus semisulcatus, Penaeus marguensis and Metapenaeus brevicornis collected from the lower stretch of the River Ganga (in the Sundarbans delta complex). The heavy metals in tissue samples were estimated using a Perkin-Elmer Sciex ELAN 5000 ICP mass spectrometer. Concentrations in shrimp species ranged as follows: Zn: 4.11 ± 0.13 – 353.45 ± 2.98; Cu: 3.43 ± 0.10– 140.49 ± 1.81; Pb: BDL - 8.21 ± 0.63 and Cd: BDL – 3.66 ± 0.12 mg kg-1 dry weight. Irrespective of species, heavy metals accumulated in the shrimp muscle in the order Zn > Cu > Pb > Cd. The concentration of heavy metals in the tissues varied significantly depending upon the locations from where the species were collected. Although the concentration of selected heavy metals were within the normal range in all stations, but at station 1 (Nayachar Island) the metal level has exceeded in the muscle of shrimp species as a food source for human consumption. The shrimp samples were collected from different locations of lower Gangetic region with different degree of industrial and anthropogenic activities and station 1 is exposed to maximum stress (in terms of pollution) from the adjacent port-cum-industrial zone of Haldia and industrial discharge of multifarious industries situated in and around the city of Calcutta (upstream to station 1) along the bank of the River Ganga. \u0000 ","PeriodicalId":259361,"journal":{"name":"Mesopotamian Journal of Marine Sciences","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129494192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
