The insidious world of the water footprint, or the hidden water of our consumption (Nagykanizsa)
Global water scarcity is becoming increasingly severe, making it vital that we are aware of the direct and indirect consequences of our consumption. This presentation focuses on the concept of the water footprint, which we will illustrate through interesting examples, demonstrating how much water we use in our daily activities. Alongside the scientific background, we will also provide practical advice on how to reduce our individual water footprint and how to become more conscious consumers.
Seeing while you still can – “Last Chance” tourism (Nagykanizsa)
As a result of environmental and human activity, numerous tourist attractions have come under threat, and it's conceivable that our children may no longer see these attractions. In many places, the number of tourists is already being restricted, or visits to former attractions are prohibited. What solutions exist? Can tourism even be sustainable, given that travel and transportation themselves represent a significant environmental burden [...]
Clear water in the glass, but from where? (Nagykanizsa)
Where does our clean water come from? What does clean water even mean? How can we produce it? We can get answers to these questions during the presentation. We recommend the presentation to both primary and secondary school students.
How much plastic do we consume? - or the presence of microplastics (Nagykanizsa)
These days, we hear more and more about plastics that pose a threat to our environment. Nature is under immense strain due to the fragmentation of plastics produced in ever-increasing quantities, as well as particles released from our clothing and cosmetics. Components invisible to the naked eye pose extraordinary health risks and have a significant impact on the ecosystem. Are these microplastic components really found in our drinking water? Do they pose a real danger to our lives? […]
Chemistry in Our Environment, Being a Chemist is Good – Spectacular Chemical Experiments (Nagykanizsa)
To promote chemistry and related fields, spectacular experiments will be demonstrated, such as fire tornadoes, fire extinguishing, production of intangible gases, fireproof handkerchiefs, etc. Within the framework of the presentation, attention-grabbing experiments will be shown that are suitable for sparking interest in science. The presentation is recommended for both primary and secondary school students.
Hydrochemical experiments (Nagykanizsa)
Within the scope of the presentation, we will demonstrate attention-grabbing experiments suitable for sparking interest in science. For water analysis, certain water chemistry parameters can be determined during the experiments, or the appearance of pollutants can be simulated. We recommend the presentation for both primary and secondary school students.
What methods can be used to estimate the ecological risk of pharmaceutical residues found in the environment? (Nagykanizsa)
The presentation is divided into three clearly distinguishable parts. Firstly, we discuss current research on pharmaceutical residues found in surface waters, the entry pathways and potential fate of these new types of pollutants, as well as detection possibilities, analytical difficulties, and the current state of science. All of this is concluded by a third part, which places the topic within the current European Union regulatory framework, […]
The Journey of Pharmaceutical Residues in Nature: Our Surface Waters with an Analytical Eye (Nagykanizsa)
Thanks to continuously developing analytical techniques, we are increasingly able to detect a wide range of active substances in ever smaller quantities. Furthermore, through ecotoxicological tests and environmental risk assessment methods, we can determine the impact that individual micropollutants have on the wildlife of surface waters. All of this data serves as information, firstly for lawmakers, thereby making priority pollutants appear in the European [...]
We can't see it, but it's still there – In pursuit of RNS/DNS (Nagykanizsa)
My presentation will discuss the PCR measurement, its process, usefulness, and related laboratory work in an easily understandable way for schoolchildren, as it's been frequently mentioned in recent years. Genetic material (RNA, DNA) is not visible to the naked eye, but with today's laboratory equipment and methods, its presence can be detected, and we can infer which groups of organisms may live/have lived in a given environment (e.g., a lake) […]
Hotels from the outside, inside, and what's behind them (Nagykanizsa)
Summary of the presentation: Hungarian tourism, and within it the hotel industry, has undergone significant development over the past decade. Whether we consider the expansion of hotel capacity or the increase in the number of guest nights spent in them, we can see that tourism in our country has been breaking records continuously since 20
