Article Synopsis
- - This study examines sedimentation patterns in four high-altitude lakes in Southern Carpathians, Romania, over the past 200 years, using a unique method to identify whether changes are due to human activity or natural processes.
- - High-resolution chronologies were created using Pb dating and supported by Cs markers, revealing short periods of increased sedimentation, up to five times the average rate, mainly linked to human actions like road construction and significant natural events.
- - The analysis highlighted significant deviations from expected natural sedimentation trends, using a first-order derivative equation to compare changes in sedimentation rates to a baseline from an isolated peat bog, offering insights into the causes of intense sedimentation episodes.
Recent carbon sequestration dynamics in four temperate SE European peatlands using Pb dating.

The last two centuries' anthropogenically-accelerated climatic changes and elevated atmospheric levels of CO are influencing the recent carbon sequestration dynamics of peatlands, resulting in high variations of growth rates, and a general ascending trend in apparent carbon accumulation rates. In the present work, Pb high-resolution chronologies and Cs alternative markers were employed to study the recent carbon-related peat properties and their evolution throughout the last two centuries in four Sphagnum-dominated bogs in SE Europe (Romania). The results revealed a recent apparent carbon accumulation rate ranging from 9.

Integrated study of both water and sediment in lakes provides important information regarding the human impact on the environment. The current work is focused on the correlation between age, source, composition, and degree of human intervention over the last 178 years and health impact of sediments from Lacu Sărat Lake (Romania), one of the most important balneo-climateric resorts in the country. The novelty relies on the fact that this is the first time the temporal patterns of metal contamination and the human health effects associated with the metal exposure from sediment core samples have been assessed.

Aspects related to soil erosion and its relation to changes in land use as well as anthropogenic influence constitute a topic of great interest. The current study is focused on a soil erosion assessment in relation to land use activities in the Pănăzii Lake catchment area.
