“…the values of PLI indicated that all the soils were uncontaminated, which was in agreement with Baz and Khalil [63] in their study of 10 sites along the central zone of the Egyptian Mediterranean coast.…”

The pollution of agricultural soils, water and plants by trace elements (TEs) in the Nile Delta Region, Egypt, is of great importance. This study aimed to investigate the spatial and seasonal variation of some TEs in the agricultural area adjacent to Kitchener Drain and to evaluate the ecological risk posed by these elements using six indices. Soil and plant samples were collected from seven sites close to the drain, while water samples were collected from the corresponding sites inside the drain during three seasons (winter, spring and fall). The results showed that all studied TEs in the soil varied seasonally and spatially among the locations around the drain. Most of the studied elements in the soil were higher in the southern and middle area around the drain. All studied elements in the soil were also higher in the winter than other seasons. Nickel and lead were almost non-detected during all seasons in plant tissues, while other elements were higher in the winter than other seasons. In contrast to the soil and plant tissues, water samples demonstrated lower or non-detected levels of TEs. The results also indicated that the values for the risk assessment indices differed among the studied TEs. Therefore, there is a risk of increasing the concentration of some metals in the study area due to anthropogenic pollution from the adjacent polluted drain through irrigation with contaminated water and spreading of contaminated dredged materials on agricultural fields.

“…They found that almost all the sites were polluted by heavy metals. The anthropogenic origin of Pb contamination was also reported in the coastal sediments of the Egyptian Mediterranean coast (El Baz & Khalil, 2018). Various anthropogenic activities along the Daya Bay, South China Sea, were reported to contribute mainly to the heavy metal contamination (Liu et al, 2018).…”

Determination of heavy metals is enormously important to determine the condition of the aquatic environment in terms of chemical pollution. In this study, a preliminary determination of heavy metal concentrations in sediment, water, and some macroinvertebrates in several sampling sites along Tawi-Tawi Bay, Philippines, was undertaken to have an initial status of heavy metal pollution in the area. Results revealed that the average concentration of heavy metals followed the order of Fe > Zn > Mn > Pb > Cu > Ni > Cd for sediment, Pb > Zn > Cu > Ni > Fe > Cd > Mn for seawater, Fe > Zn > Mn > Cu > Pb > Ni > Cd for spider conch (Lambis lambis Linnaeus, 1758), and Fe> Zn > Pb > Ni > Mn > Cu > Cd for sea cucumber (Holothuria scabra, Jaeger, 1833). However, all these determined heavy metals were within the safety limits set by WHO, US (EPA and FDA), and EMA. This study suggests that despite the anthropogenic activities in the coastal areas, heavy metal contamination in Tawi-Tawi Bay has not exceeded the safety limits.

“…Significant Cd pollution in the Nile River bottom sediments between Aswan and Esna, near the phosphate shipping harbors [ 21 ]. The Nile River and its tributaries are pretentious by various human-caused activities, including the disposal of sewage sludge and wastewater, agricultural activities, industrial processes, and the use of phosphate fertilizer [ 2 , 22 , 23 , 24 ]. According to Egypt’s Nile River studies [ 25 , 26 , 27 , 28 , 29 , 30 ], hazardous metals such as Cd, Pb, and Fe have been found in important economic fish species, aquatic plants, and water.…”

Heavy metals such as cadmium (Cd) pollute the environment. Heavy metal pollution endangers the Nile River since it serves as an irrigation and freshwater source for the cities and farms that line its banks. Water and sediment samples from the Nile River were tested for Cd content. In addition, a sequential experiment analytical method was performed to determine the metal’s relative mobility. According to the data, there is an average of 0.16 mg kg−1 of Cd in sediments. The BeniSuef water treatment plant and brick factory, the iron and steel factory of Helwan, the oil and detergent factory of Sohag, and the discharge of the cement factory in Samalut had the greatest concentration of Cd in their vicinity. According to the risk assessment code, there are four categories of Cd: residual (57.91%), acid-soluble (27.11%), reducible (11.84%), and oxidizable (3.14%). Bioavailable and mobile Cd levels in sediment and water were found in Beni Suef, Aswan; Helwan; Samalut; Sohag; and Helwan. Because the other metal is highly bioavailable, its concentration is not a risk factor at the Samalut station. Cd’s toxicity and bioaccumulation make it an extra hazard to aquatic animals and human life. There should be a deterministic approach to monitoring Cd near industrial sources.
