Article Synopsis
- The study analyzes the state of curative mud deposits in Estonia as of 2022, focusing on changes over the past decade and the quality of the mud.
- A total of 64 samples were taken to investigate hazardous substances, with 1649 measurements conducted on various factors like organic content, microbiology, and heavy metals.
- Results showed stable organic matter levels, low microbiological contamination, fluctuating petroleum concentrations, minimal pesticide presence, and a decrease in heavy metal levels since 2013-2014, providing vital information for curative mud-related business adherence to new regulations.
This paper provides a methodological protocol for measuring diameter and other properties of mineral sand grains using an image analysis technique. The aeolian sand influx (ASI) from coastal bogs has been used to reconstruct changes in the past storminess. However, concentrations of sand grains in peat deposits, from which the ASI is calculated, tend to be low, and sieving and laser diffractometry cannot be applied.

In the current study, we used a combination of GIS-based methods (satellite, orthophoto, ground validation) to evaluate regional estimates of standing water body (SWB) inventories in two geographically different parts of Europe - France, and Estonia. In our study the SWBs surface area threshold limit was 0.
