Article Synopsis
- The study analyzed the chemical compositions of 201 surface and 53 deep sediment samples from Chaohu Lake, focusing mainly on sediments from 50-100 cm depth, which revealed insights into historical climate conditions.
- Results indicated weak chemical weathering in the Chaohu Lake Basin, suggesting a cold and dry palaeoclimate, with sediment deposition linked to the Little Ice Age (AD 1380-1880).
- Correlations between various chemical indices and sediment components provided information on palaeoclimate characteristics, highlighting significant positive relationships with Cr and N, while showing little correlation with heavy metals like Cd, Pb, and Hg.
