“…It is also important to identify the sources of this pollution in order to establish an effective program of measures. In many previous studies, successful results have been obtained using multivariate analyses, which are known to be effective tools for determining the sources of heavy metal pollution in sediment [62][63][64][65] .…”

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...

“…Wind easily transfers the polluted sediment particles as dust storms and the pollution emission occurs naturally. Hence, analysis of the surface sediments on the playa can reasonably reflect the composition, toxicity and the pollution rate of dust storms 20,21 . Although, some studies have been reported in this respect, to the best of our knowledge, there are currently no published papers discussing the heavy metal analysis of the sediment of Jazmurian playa, This is the first study to examine the contamination of sediments of a basin dried due to climatic variations and human activities.…”

Jazmurian playa was an ephemeral lake with a large catchment in southeast iran, which dried up over the last 10 years as a result of prolonged drought. As the lake was recipient of incoming industrial water with trace metals deposited to the sediment, the dust is the cause of environmental concern of the region and requires evaluation and better management. The aim of this study was to evaluate the environmental and ecological pollution of Jazmurian playa. Hence, 24 collected surface sedimentary samples were analyzed with ICP-OES. The environmental pollution indices including degree of contamination (cd), geoaccumulation index (igeo), enrichment factor (ef), pollution load index (PLI) and potential ecological risk (PER) were determined. The study revealed moderately to strongly pollution levels of pb, ni and Al, while Dy, pb, Y, Yb, Sm, te, U, cu, Mn, Sc represented moderate pollution. The EF values indicated four sites were highly enriched with Dy, Pb and Ni. The PER results showed high risk for four sites and considerable risk for others. Cluster analysis illustrated interconnection between the contaminants and the sites with major pollution at six sites. Obviously, climate change has considerable complex environmental impacts through transformation of local water and sediment pollution problem.

“…Pencemaran lingkungan, terutama di ekosistem perairan, adalah salah satu masalah lingkungan terpenting pada saat ini. Pencemaran dalam ekosistem perairan disebabkan oleh berbagai polutan seperti logam berat termasuk Cr(VI) (Duruibe et al, 2007;Kyzas et al, 2014;Guan et al, 2018). Pencemaran pada ekosistem perairan menyebabkan degradasi ekosistem perairan secara bertahap.…”

One of the most severe environmental problems is heavy metal pollution such as Cr(VI) in aquatic ecosystems. Cr(VI) is toxic and carcinogenic heavy metals pollutants that persistent and easily accumulated through the food web. Accumulation of Cr(VI) concentration in the aquatic ecosystem gradually increases with the increases of industrial activity. Therefore, Cr(VI) concentration in aquatic ecosystems should be monitored continuously, and thus, suitable and accuracy monitoring technologies are necessary. This study analyzed the utilization of biofilm as a biomonitoring agent of Cr(VI) in the Badek River, Malang City. The concentration of Cr(VI) inside the biofilm and the surrounding water of biofilm were investigated. The results revealed that the concentrations of Cr(VI) inside the biofilms were hundred times higher than the surrounding water. The biofilm may accumulate Cr(VI) from the surrounding water resulting in the Cr(VI)-rich microenvironment inside the biofilm. The adsorbed Cr(VI) is retained mostly in the interstitial water of the biofilm matrices. The findings in this study suggested that the biofilm can be used as a potential biological agent to monitor of Cr(VI) pollutant in the river ecosystems.
