“…Since Al has relative stability in sedimentation, it has been used as the conservative element (Hyun, Lee, Lee, & Choi, 2007;Yao & Xue, 2016;Yuan et al, 2011) that aids in differentiating the natural and anthropogenic sources input in the investigated heavy metals. In this study, the procedure followed in normalization was adopted from Al-Mur et al (2017) and Bhuiyan et al (2015).…”

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.

“…Under the assumption that there is a constant sediment supply rate over a period of isotope emission, more detailed chronologies can be constructed (Diaz-Assencio et al, 2014;Yao and Xue, 2016). These conditions, with sufficient rapid accumulation and constant sediment supply rates, commonly occur in water reservoirs like shelf seas, harbors or dam reservoirs (Frignani and Bellucci, 2004;Baeza et al, 2009), whereas the periodical nature of overbank sediment accumulation makes detailed dating of fluvial sediments much more difficult.…”

The periodical nature of overbank sediment accumulation makes their detailed dating much more difficult than dating sediments in water reservoirs. To improve the commonly used dating with 137Cs, we combined this method with Pu isotopes and heavy metals in order to date sediments of the Chechło River (southern Poland), which was polluted by a lead-zinc mine. We analyzed 137Cs, Pu isotopes and heavy metal concentrations in three profiles of overbank sediments and in two profiles of subsidence basins in the lower river reach. The results indicate a lower accuracy and higher uncertainty of the overbank than the dating of reservoir sediments. The application of plutonium isotopes provided very important information validating caesium peaks or providing the principal information regarding horizons dated with heavy metals. The obtained dates give the earliest possible age of particular horizons with the actual sediment deposition delayed by several to a dozen years. This investigation shows that using plutonium radioisotopes can be a useful tool for dating, particularly of the youngest overbank sediments where numerous sedimentation gaps cause uncertainties in the application of other methods, e.g. radiocaesium and heavy metals.

Sediment records of the metal pollution at Chihu Lake near a copper mine at the middle Yangtze River in China

Abstract: Two short sedimentary cores were collected in 2012 from Chihu Lake in the middle Yangtze River Basin using a gravity corer. Heavy metals, including Pb, Cu, Zn, Cd, Cr, Co, Ni and Mn, and major elements, including Al, Fe, K, Mg and Ti, were
