“…Previous research in the Damietta region indicated that soil, fish, and plants have a high concentration of Pb due to urban pollution (Mandour et al, 2021;Ebeid et al, 2022). In our study, the lead accumulation in different organs showed variations between males and females in the same species.…”

Anthropogenic contamination is spreading through every environment on the planet that affects the whole biota. Negative effects have been observed recently in a number of taxa, including birds. Birds are crucial as bioindicators as one of the best studied groups of organisms because they are noticeable, relatively simple to observe, and the subject of public interest and concern. Therefore, evaluation of lead (Pb) levels in the liver, muscle, kidney, and feathers of laughing dove (Streptopelia senegalensis), Egyptian barn swallow (Hirundo rustica savignii), and house sparrow (Passer domesticus niloticus) was done. These bird species, which live in the coastal region of Damietta, have various feeding routines, habitat preferences, and mating strategies. In both the breeding and nonbreeding seasons, these wild birds were collected. Measurement of the levels of lead (Pb) in their liver, kidney, muscle, and feathers were evaluated. The results showed that females of laughing doves and barn swallows had significantly higher Pb concentrations than males, while males of house sparrows accumulated significantly higher Pb concentrations than females. This could be attributed to the active food search in both female laughing doves and swallows, and male sparrows. House sparrows, with the widest range of distribution near main roads, showed the highest concentration of Pb, especially in the liver, kidney, and feather than laughing doves and swallows, which prefer the wild rural areas. Histological examination of the gonads revealed unhealthy testes and ovaries. The ovarian tissue was less impacted than the testicular tissue, especially during the nonbreeding season. Compared to the dove and swallow, the sparrow's gonadal architectural histopathological findings were more noticeable. It seems that testes are more affected and more related to the results of lead measurements, and can be used as a bioindicator for heavy metal pollution. The findings offer also some proof of the house sparrow's potential as a biomonitor for urban heavy metal pollution. This research emphasises the significance of using biomonitors from various habitat types and feeding guilds.

“…These differences might be explained by the activity in both harbours, with five times more mooring capacity in PC harbour relative to C harbour. Ebeid et al [40] also observed strong Cu contamination in Egyptian harbours, with concentrations above 1000 mg kg −1 , similar to those measured in PC harbour in the technical zone. The copper concentrations measured in the two studied ports are higher than those measured in the marina at Monastir.…”

“…As measured for Fe and Al, terrigenous elements (Cs, Li, and Rb) were significantly (p < 0.05) greatest in C harbour. Both harbours exhibited distinct sediment characteristics, suggesting differences in hydrodynamic regimes and connections with their respective watersheds [39,40]. The dominance of fine fractions in C harbour might favour contaminant accumulation in the sediment [31,32], bearing in mind that sediment contamination is also controlled by the supply of contaminants from the water column.…”

Marinas are semi-enclosed environments characterised by reduced hydrodynamic energy, high sedimentation rates, and reduced oxygen levels. The ongoing development of activities and infrastructure construction are leading to deterioration in the quality of coastal aquatic environments, creating environmental risks. Trace metal elements (TMEs) and organotins are significant contaminants, prompting this study to evaluate the added value of spatiotemporal monitoring compared to one-time sediment assessments. Two Mediterranean harbours, Port Camargue (PC) and Port Carnon (C), differing in morphology and size, were monitored for a year with regular water sampling, focusing on TMEs and organotins. Sediment contamination, notably in the technical zone, revealed concentrations of Cu (309 and 1210 mg kg−1 for C and PC, respectively), Zn (242 and 425 mg kg−1 for C and PC, respectively), and tributyltin (TBT) (198 and 4678 µg (Sn) kg−1 for C and PC, respectively) surpassing the effect range medium (ERM), while other marina stations generally stayed below this threshold. Spatiotemporal water monitoring highlighted concentrations above environmental quality standards (EQS) at all stations of the larger marina. This exceedance was systematic for Cu and Zn in all samples, ranging respectively between 2.54 and 37.56 µg (Sn) L−1 and 0.63 and 33.48 µg (Sn) L−1. A notable temporal dynamic for TBT and Cu was also observed. Conversely, the open marina, connected to the open sea, rarely exhibited concentrations above EQS in water, despite sediment concentrations occasionally exceeding ERM values. This underscores that risk assessment in these ecosystems cannot rely solely on sediment characterisation.

“…Accreting aquatic sediments can be extremely important sources of information, mostly because they have the potential to behave as natural archives through the retention of significant information about the surrounding environment at the time of their deposition and accumulation [6,[9][10][11][12][13][14]. Specifically, their role as recorders of past chemical signatures makes them ideal matrices for the reconstruction of relatively recent anthropogenic impacts [15][16][17][18][19][20][21]. Indeed, the comparison with historical information allows the attribution of observed changes along the core profile to specific activities/management choices.…”

The coupling of scientific evidence from sediment cores with historical information represents an effective way to reconstruct and quantify recent anthropogenic impacts in transitional and marine-coastal areas. These are both key points pertaining to studies that aim at establishing the responsibility for envi ronmental pollution. Good practices for the selection of sampling sites and specific survey techniques are fundamental to understand pollution histories and dynamics, together with reliable dating methods and analytical procedures. In addition, a certain degree of flexibility and willingness to explore different research pathways is necessary, particularly when unexpected questions arise from scientific data or from requests posed by authorities in charge of preliminary investigations or court debates. In this paper, two different study cases are reviewed, and the approaches developed to tackle with specific issues are presented. Its main purpose is both to explain study paths undertaken to answer challenging scientific-legal questions and to provide examples for developing countries that present similar risks of uncontrolled industrialization. Results were used in preliminary investigations or court debates for the attribution of responsibility for environmental pollution to past or present industrial managements. In addition, they were fundamental for other studies aiming at implementing models that simulate the fate and distribution of contaminants and human exposure. In the Augusta Harbor, an integrated approach merged archive information, bathymetry, and high-resolution seismic profiles with the results of an independent tracer (hexachlorobenzene, HCB). This approach helped attribute the presence of high surficial Hg concentrations to resuspension and redistribution of deep sediments caused by dredging and maritime traffic and not to active outfalls. In the Venice Lagoon, an extensive literature search supported analytical results for the correct identification of industrial processes responsible for the contamination by polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) in the canals of the Porto Marghera Industrial Area. In addition, sedimentary profiles of PCDD/Fs in local salt marshes (“barene”) recorded well the events relative to the industrial development and management of the area reported by historical documents, confirming their potential for this kind of investigation.
