the concentrations and sources of heavy metals in shallow sediments in Lake Bafa were investigated. the concentrations of nine heavy metals and the total organic carbon content in sediment samples were determined for between Summer 2015 and Spring 2016. The mean contents of heavy metals were in decreasing order fe > Mn > ni > cr > Zn > cu > co > pb > cd. Sediment quality guidelines indicate that Cr, Cu, and Ni pose a considerable threat to the aquatic ecosystem in Lake Bafa. Site L3 was found to be contaminated with cd, cr, and ni, and the pollution load indices suggest that these metals had anthropogenic sources. the sediment samples were notably enriched with cd and ni. there is no consistent trend for seasonal effect in terms of the sample locations. However, at all sampling points, an increase in heavy metal concentrations was observed in the autumn. the results of a multivariate analysis indicate that the sources of co, cu, fe, Mn, pb, and Zn were all natural, the sources of cd were anthropogenic, and the sources of ni and cr were both anthropogenic and natural. these results highlight that cd, cr, and particularly ni represent the most serious threat in terms of heavy metal pollution in the ecosystem of the lake. Heavy metals mainly enter aquatic environments as a result of a variety of human activities (e.g., agriculture, combustion, corroded underground pipes, industrial plants, sewage, smelting, and vehicles) 1-3. Exposure to heavy metals has been linked to various negative health effects, including cancer, behavioural problems, impaired intelligence, developmental problems, kidney damage, and miscarriage or stillbirth 4. Heavy metals are not readily degraded in the environment, and those that enter a water body can remain there for some time. They are usually found in low concentrations in aquatic systems 5 , and high concentrations of heavy metals in sediments can indicate anthropogenic rather than natural sources 6,7. Heavy metals are poorly soluble in water, so predominantly sorb to suspended particles that then settle as sediment 8. Heavy metals can thus enter the food chain in the aquatic environment, and become available for accumulation in biota 9. Fish, which are at the top of the food chain and are an important food source for humans, can accumulate heavy metals in their tissues 10 , and this characteristic makes them an effective indicator of pollution 11. Accordingly, assessment of pollution from heavy metals in sediments in the environment is very important in terms of its effects on aquatic organisms and human health 12. Lake sediments are a sink for heavy metals 13,14 , and heavy metal concentrations are generally higher in sediment than in water 15. Indeed, concentrations of heavy metals in water are sometimes lower than detection limits, meaning that sediment should be analysed to assess levels of contamination by heavy metals in the aquatic system 16-18. Lake sediments mostly act as a sink for heavy metals; on the other hand, they can also act as a source to the overlying water 19,20. C...

“…on the bottom of the water as sediment [Yang et al, 2014; Baran et al, 2019]. Hence, sediments are a place for accumulation of various pollutants that reach the aquatic environment from various sources [Ridgway and Shimmield, 2002;Luna et al, 2016], as well as a source of endogenous contaminants in the aquatic environment [Ciutat et al, 2007].…”

This study aimed to analyze the heavy metal contamination in sediments and their potential ecological risks. The sediment samples were collected using PVC pipes and grab samplers at nine study sites in Youtefa Bay, namely five sites in the mangrove ecosystem, two sites in the estuary, and two sites in the middle of the bay. The heavy metal content was analyzed using Atomic Absorption Spectrophotometry. The results of the analysis of the heavy metal content in the sediment were in the following order:

“…Metals have great ecological significance due to pose significant toxicity to consumers at the top of the food chains and tendency to accumulate in both sediment and biota Bat, 2017;Bat et al, 2021). Metals absorb suspended particles and settle as sediment because they are weakly soluble in water (Bat and Özkan, 2019;Algül and Beyhan, 2020;Yang et al, 2014). Metals released from sediments into the overlying water generate secondary pollution, which can harm the aquatic system's biological status (Bat and Kurt, 2020;Varol and En, 2012;Niu et al 2015).…”

This study aimed to investigate the ecological risk level of İzmir Inner Gulf. Based on the findings, port, industry, settlement and transportation activities generated Mo, Pb, Cu, Cd, Zn enrichment. Modified hazard quotient (MHQ) point to a high level of pollution and toxic effects for Ni and Cr; significant pollution and toxic effects for As and Hg, and moderate pollution and toxic effects for Pb, Zn, Cu. According to the ecological contamination index (ECI), the inner gulf is significantly-highly polluted. Toxic risk index (TRI) and potantial ecological risk index (PERI) are also consistent with these data. According to the ECI, the inner gulf is significantly/highly polluted. TRI and the PERI are also consistent with these data. Cd has created a significant ecological risk in all seasons due to its high toxicity. Cu and Pb have caused moderate ecological risk in local areas near the port. A moderate potential ecological risk has been identified in all seasons throughout the inner gulf.
