“…The heavy metal pollution in marine sediments, beaches, and seashells along the Red Sea coast was investigated using numerous authors (Abdelkader et al, 2018 ; Attia & Ghrefat, 2013 ; El-Metwally et al, 2019 ; El-Sorogy et al, 2012 ; Madkour, 2005 ; Madkour et al, 2012 ; Mansour et al, 2011 ; Philobbos et al, 1983 ; Ramadan & Zaid, 2013 ; Redwan & Rammlmair, 2017 ; Salem et al, 2014 ; Temraz & El-Sawey, 2017 ). The overall contamination came from lithologic nature and anthropogenic activities such as land filling, oil pollution, and utilizing antifouling and anticorrosive paints from the fishing and shipping processes of phosphate ore.…”

Globally, the environmental contamination of stream sediments due to geogenic and anthropogenic sources is of growing concern. In this study, the heavy metals (Cd, Co, Cr, Cu, Ni, Pb, and Zn) in 22 superficial sediments in Wadi Asal, Red Sea, Egypt, were explored to assess sediment sources, the mobility of chemical species, and the degree of contamination in sediments. Therefore, the total heavy metal values in the fine fraction (< 63 μm), a five-step sequential extraction on selective samples, risk assessment, and principal component analysis (PCA) were applied. The mobility of heavy metals in Wadi Asal sediments, according to non-residual fraction percent, declines in the following order: Cd (90.9%) > Pb (85.2%) > Co (84.4%) > Cu (80.8%) > Zn (75.9%) > Ni (48.4%) > Cr (39.6%); indicating the high mobility of Cd, Zn, Pb, Cu, and Co. The mean metal contamination factor (CF) order is Cd (10.96) > Ni (3.91) > Cr (2.77) > Zn (2.18) > Pb (2.10) > Co (1.12) > Cu (0.70). The Geo-accumulation Index (Igeo) is decreased in the following order: Cd (2.19) > Ni (0.78) > Cr (0.55) > Zn (0.44) > Pb (0.42) > Co (0.22) > Cu (0.14). The risk assessment code (RAC) revealed very high to high risk for Cd, Co, and Pb. The results pointed out that the metals Cr, Co, Cu, and Ni are from geogenic sources, while Zn, Cd, and Pb are from anthropogenic sources due to Pb–Zn mining activities. Based on the threshold effect level (TEL), Cd, Cr, Ni, and Pb have adverse effects on living organisms. According to these findings, the area along Wadi Asal and the downstream regions on the beach are highly polluted and heavy metal monitoring in sediments and aquatic organisms is recommended.

“…Mansour et al (2013) suggested that several anthropogenic and natural disturbances influence the marine environment of the Hurghada area including pollution by: oil spills, wastewater discharge, effluents of desalination plants, and building activities along the seashore, marine traffic, and landfilling and dredging operations. In addition, several studies on marine surface sediments of the Egyptian Red Sea have been carried out (Madkour et al 2012). The marine environment of the Hurghada coastal area has suffered substantial environmental impact from anthropogenic activities due to the increasing population growth and the rapid development taking place in the tourism industry and their negative impacts on the marine environment (Mansour et al 2013).…”

The current study aims to calculate and assess the asymmetry of the two goatfish species, Yellowstripe goatfish Mulloidichthys flavolineatus (Lacepède 1801) and Red Sea goatfish, Parupeneus forsskali (Fourmanoir & Guézé 1976) collected from Hurghada fishing harbour, Egypt. The asymmetry valuation for M. flavolineatus and P. forsskali is imperative to demonstrate the impact of asymmetry on the larvae settlement in this vital fishing ground. Asymmetry was calculated for the saccular otolith (Sagittae) biometry, namely length, width, and mass. The results showed that the otolith height had a lower asymmetry value than the otolith length for the two goatfish species inspected. No relationship between the asymmetry value of otolith length and width and total fish length was observed. Both goatfish species’ calculated otolith mass asymmetry was higher than that of many teleost fish species.

“…An extended reef flat with seagrass and seaweed beds suitable for fish and shellfish breeding characterises this site. 13 Safier Hotel area is one of Hurghada resorts which is located 8 km south of Hurghada at 27° 12' 14" N, and 33° 51' 07" E, seen in Figure 1. Most of the activities taking place in the area are landfilling, dredging and reclamation of the intertidal zone.…”
