Holocene paleoenvironmental changes recorded in the sediments of the karst Krka River estuary (eastern Adriatic coast, Croatia)

Here, a reconstruction of late Quaternary sea-level fluctuations and environmental changes from Prokljan Lake is presented. Prokljan Lake is a part of the karst Krka River estuary situated in central Dalmatia (Croatia). Subbottom profiles were acquired to examine the basin geomorphology, whereas four sediment cores spanning the Holocene age were used for paleoenvironmental reconstruction. On the basis of sedimentological, geochemical, and paleontological proxies supported by 22 radiocarbon dates, a model of evolutionary progression from the fluvial calcareous tufa barrier system to salt-wedge estuarine conditions is presented. Following the subaerial erosion during the postglacial transgression, a tufa barrier system developed in Prokljan Lake, enabling tufa lake formation with fluvio-lacustrine sediment accumulation until the early Holocene. The sedimentary succession shows dynamic environmental and salinity changes as the Krka River canyon and Prokljan Lake were progressively flooded in the Holocene. Our results revealed a low salinity brackish lacustrine environment at the beginning of the Holocene (ca. > 10.9–8.4 cal kyr BP), with marine intrusion through porous tufas and karst. A further rapid sea-level rise caused an increase in the water depth and flooding of calcareous tufa barriers in the period from 8.4 to 7.5 cal kyr BP, which coincided with the Holocene pluvial period. Further sea-level rise and more arid climate conditions in the period 6.1–3.0 cal kyr BP caused the mixing of marine and freshwater layers, with the formation of a partially mixed or slightly stratified estuary. Late Holocene sediments (3.0–1.9 cal kyr BP) represent sea-level stabilization and the establishment of present-day salt-wedge estuarine conditions. Anthropogenic pressure, manifested as increased catchment-area erosion and organic matter isotopic signature changes, was detected in the last 0.6 cal kyr BP.

High-resolution seismic record of the Quaternary palaeoenvironments along a Dalmatian-type coast (Lošinj Channel, Adriatic Sea)

Here, we offer the first detailed assessment of geomorphic features and late Quaternary sedimentation dynamics in the Loˇsinj Channel in the Adriatic Sea. The present study attempts to resolve the complex evolution of the environments by applying high-resolution seismic records that build upon sediment core data. Within this coastal karst basin, a significant amount of sediment accumulated during the Quaternary. Notably, the existence of several prominent erosional and depositional environments was revealed. We distinguished recurrent episodes of fluvio-lacustrine and marine sedimentation that probably occurred since Marine Isotope Stage (MIS) 6. The preserved record consists of erosional features and subparallel and oblique reflectors attributed to glacial periods (Seismic Units SU-II, SU-IV, and SU-V). Interglacial units are acoustically semitransparent and generally reflection-free (Seismic Units SU-I and SU-III). The mutual influence of sea level and climate change, sill depth, and karst hydrology enabled environmental changes in the Loˇsinj Channel. The area proves to be important for Quaternary studies because it contains a long sediment succession spanning at least the middle and late Pleistocene and Holocene. Our study has implications for the assessment of the long-term palaeoenvironmental evolution of similar coastal settings and reconstruction of the regional palaeogeography which is in turn crucial for understanding prehistoric human occupation and/or dispersal. This is one of the few well-preserved records in the Adriatic Sea that provides insight into submerged landscapes and sea levels since the penultimate glacial.

Inventory of mercury, lead and cadmium in soil : a required prerequisite for proper assessment of large scale disastrous effects in case of war or industrial environmental accidents

Proper assessment of disastrous war effects requires a good knowledge on heavy metal inventory in soil. Anomalously high values of Pb, Cd and Hg (the most poisonous heavy metals within the ingredients of explosive components) have been recorded at all accidental sites, including the city of Zagreb. The results of the investigation are the first geochemical maps of Hg, Pb and Cd of the city of Zagreb with general localisation of the polluted areas, and loose determination of the major pollution sources and mechanism. Inventory of the present state, on the other hand, is an unavoidable prerequisite for the proper evaluation of possible war effects within an area of interest.

Spatial variability of magnetic susceptibility (χ), soil organic carbon (SOC) and total nitrogen ... more Spatial variability of magnetic susceptibility (χ), soil organic carbon (SOC) and total nitrogen (TN) concentrations were analyzed using geostatistics method in different soil horizons from farmland in the North China. Results showed that a significant difference in SOC and TN contents, while no significant difference in χ was observed at two soil horizons using the t-test. The average values of χ 93.0 × 10 -8 m 3 kg -1 , SOC 11.25 g kg -1 and TN 1.03 g kg -1 were higher at the 0-20 cm than those measured at the 20-40 cm depth, respectively. The value of frequency dependent susceptibility (χ fd ) was greater than 6% indicated the formation of superparamagnetic particles through pedogenesis and/or human activities. The isotropic semivariogram models of χ, SOC and TN were fitted to spherical model. A clear variogram of soil properties with a medium spatial dependent was observed. The range of spatial correlations was determined to be approximately12 km, which seemed to be characteristic for a regional scale. The kriging interpolated maps provided information for soil monitoring and management. Geometric and small spherical magnetic particles were identified by microscopy. Vertical distributions of soil properties proved that soil magnetic signature mainly originated from lithogenic and anthropogenic contribution.

Trace element release from two different base alloys under conditions of imitating oral saliva

Co, Fe, Zn, Ni, and Cr were released from both dental alloys and to a different extent. The manufacturer didn't declare the presence of neither Ni, Zn and Fe from Co-Cr-Mo dental alloy, nor the release of Co and Zn from Ni-Cr dental alloy. The released amounts of Fe and Zn may only improve the subjects dietary status in respect to these elements, whereas Ni, Cr and Co are potent allergens which may impede the biological compatibility of the entire protethic structure in vivo.
