“…where, C metal is the total metal concentration and C background represents the average background value of the metal in sediment. The CF was then classified into four grades as given by Al-Mur et al (2017); El-Sayed et al (2015) and Sabo, Gani, and Ibrahim (2013). Another index that was used in determining the contamination level was I geo .…”

“…On the other hand, EF is a powerful tool that is useful in regional comparison of heavy metals in sediments (El-Amier, Elnaggar, & El-Alfy, 2017;El-Sayed et al, 2015). The EF is useful in assessing the chances of human influence on heavy metal concentrations in the sediment (Al-Mur et al, 2017). The use of EF requires a selection of a normalizing metal which is not easily affected by anthropogenic activities.…”

“…Lake sediments record a large volume of information about changes in the lakes and their catchment giving rich history of human-nature interactions with the waterbody (Al-Mur, Quicksall, & Al-Ansari, 2017;Ntakirutimana, Du, Guo, Gao, & Huang, 2013;Sahli et al, 2017;Yanhong, Sumin, Barttarbee, & Yuxin, 2004). The information, largely include; land use, climatic, and environmental changes, which can be used to reconstruct the pollution history of a lake (Al-Mur et al, 2017;Skordas, Kelepertzis, Kosmidis, Panagiotaki, & Vafidis, 2015). Further the sediment cores provide chronologies of sediment contamination in aquatic environment (Al-Mur et al, 2017).…”

“…The sediments can also be used in understanding the spatial and seasonal variation of contaminant concentration levels (Lau & Chu, 1999). According to Al-Mur et al (2017); Zanjani-Jamshidi and Saeedi (2017) and Sahli et al (2017) study of sediment core vertically provides a reliable historical natural and anthropogenic metal record together with accumulation of various elements over time. In aquatic system, most metals are predominantly associated with the deposited sediment.…”

Sediment cores hold large information on the history of human interactions with lakes and surrounding environments. Hence, this study investigated the geochronological and heavy metals characteristics of sediment from Lake Naivasha, Kenya. Geochronological characteristics were established from sediment cores, using 210 Pb and 137 Cs. On the other hand, heavy metals; Al, As, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were analyzed using Inductively Coupled Plasma -Optical Emission Spectrometer (ICP -OES). Their probable sources were predicted using Pearson's correlation and Principal Component Analysis (PCA) while heavy metal contamination levels were assessed using geoaccumulation Index (Igeo), Contamination Factor (CF) and Enrichment Factor (EF) pollution indices. Results showed that the cores were about 140 years old with an estimated average mass sedimentation rate of 0.32 g/cm 2 /yr. Vertical fluctuations of heavy metal contamination were observed along the sediment cores with high values recorded near the surface. Further, PCA and pollution indices showed that Al, Cr, Cu, Ni, and Pb were from natural sources while, Zn, Mn, Fe, and As, (in order of contamination levels), were both from natural and anthropogenic sources. Therefore, this study showed the geochronological trends of sedimentation and impacts of human activities on Lake Naivasha.

The aims of the study were to investigate the concentration of trace elements, nutrients, and ecotoxicity in bottom sediment cores collected from the silted part of the Rożnów reservoir (Southern Poland). Significant differences in the content of nutrients, trace elements, and ecotoxicity between five sediment cores were found. However, in the vertical distribution, there was no high variability of the above parameters, which means that the intensely suspended matter transported by the Dunajec river is and, at various times, has been homogeneous. Significant correlations between nutrients and trace elements (r = 0.33–0.91, at p ≤ 0.05) point to the same sources of the above-mentioned substances and similar levels of contamination in the sediment cores. However, the PCA results showed that cadmium and phosphorus in the sediment cores had different behaviors than other elements and can be associated mainly with anthropogenic sources. According to the degree of contamination factor, sediment cores fall under the category of considerable contamination of metals. Geochemical factors indicated that nickel, chromium, and cadmium (only sediment core C1) were found to be the cause of significant pollution in the sediment cores. Toxicity assessment found that most of the bottom sediment samples were classified as non-toxic or slightly toxic, only 10% of the sediment samples were toxic for Vibrio fischeri, and 6% of the samples were toxic for Sinapis alba. The two test organisms showed a different sensitivity, and higher toxic responses were recorded for V. fischeri than for S. alba. Cadmium and phosphorus were associated with toxicity for S. alba (r = 0.29–0.58, at p ≤ 0.05), whereas TOC, N, and S, and Ca for stimulation of growth this plants. Trace elements (r = 0.32–0.51, at p ≤ 0.05) and nutrients (S, K, Mg, Na, r = 0.44–0.58, at p ≤ 0.05) were positively correlated with inhibition of luminescence of V. fischeri. The studies of concentration and relation between trace elements, nutrients, and ecotoxicity are important in the ecological risk assessment and describing the quality of sediments with multiple sources contamination.
