Pre-Conference Mini – Workshops

PRE-CONFERENCE MINI-WORKSHOPS will be held at the premises of the Department of Geology and the Museum of Sciences and Technology in the campus of the University of Patras.

A minimum of 15 participants is required for any mini-workshop to be included in the final program of GSG2022. Therefore, dates and time intervals are preliminary.

Attendance of mini-workshop(s) is covered by the conference registration fee.


W1. Laboratory chemical methods for assessing environmental and health risks of Potentially Toxic Elements in earth materials

Potentially Toxic Elements (PTEs) in various earth materials such as rock, soil, sediment and dust are distributed among different fractions and forms with different solubility and reactivity in relation to plant uptake, leaching to groundwater and absorption by the human body. As such, the determination of total or pseudototal concentrations of PTEs in is of little significance for evaluating potential risks for the environment because it is assumed that 100% of the contaminant is released and subsequently involved in chemical and biological processes. As an alternative, within the trending risk based environmental management, chemical methods for evaluating the environmental availability of PHEs have been proved to be very useful tools at hands of geochemists. Such methods include single extraction procedures and in vitro digestion models that have been developed to provide a conservative measure of the relative hazard to ecological and human receptors. Prospective applicants to this mini workshop are undergraduate and postgraduate students and all geo-environmental scientists that would like to expand their knowledge on availability and use of such methods.

Workshop Goals

  • Provide an overview of currently available laboratory methods and discuss the latest practices for assessing environmental and health risks of earth materials including soil, sediment, indoor and outdoor dust etc.
  • Describe methods of measurement uncertainty estimation and how it is affected by such issues as sample preparation, sample heterogeneity and data acquisition.
  • Discuss and provide hands-on practice and guidance for data treatment and interpretation for the estimation of risks associated with ecological and human health.

Workshop Content

  • Presentation of a set of available methods commonly used by geoscientists in the chemical laboratory for assessing environmental risk of PTEs in earth materials
  • Examples of use of such methods in various environmental geochemistry studies from Greece and abroad

Practical- computer based exercises on data analysis and interpretation of geochemical data available by the organizers

W2. Current trends and future perspectives of Machine Learning applications in Geoscience and Engineering

The workshop will focus on applications of machine learning and artificial intelligence within the domains of geoscience and engineering geology. Specialists from academia and leading companies will come together to exchange insights on the pros and cons, the latest developments and new technologies and applications. For attendees, the workshop will be not only an easy way to learn about and train themselves on the latest tools and technologies related to ML, but also allows them to hear from the best minds of the industry on relevant topics. The proposed event aims to teach the attendees the practical applications of machine learning with hands-on project experience. In technical demonstrations and hands-on training participants can learn how to implement machine learning in their research.
