Hello! My name is Johanna and I am from Helsingborg, Sweden. I have a passion for science, and driven by my curiosity to understand the world I hope to contribute to its betterment.
Tell us what the water concern in your country is!The water concern in Sweden encompasses various aspects, including the presence of toxic chemicals. There has been growing awareness regarding the environmental impact of chemicals and their toxicity for aquatic organisms. The problem is that prohibited chemicals are often replaced by substitutes with similar effects.
This is what I think is one of the solutions for a sustainable future:I believe that knowledge is fundamental for a sustainable future because it empowers individuals, communities, and societies to make informed decisions and take responsible actions. Therefore knowledge serves as a compass, guiding us towards sustainable solutions.
Receipts 2022 – toxic for aquatic organisms?
Chemicals are constantly present in daily life and appear in thermal paper such as receipts. By littering chemicals frequently end up in ecosystems, namely lakes and streams. The purpose of this study was to analyze whether receipts distributed 2022 were toxic for aquatic organisms. The method studied the mortality of Daphnia magna when exposed to receipts from various stores. Additionally, the study analyzed whether the thermal papers contained phenol by performing the Molisch’s test. The result of the model study indicated a relation between mortality and exposure of receipts. Molisch’s test also confirmed the presence of phenol in all analyzed thermal papers. The conclusion that could be drawn was that further research was necessary to confirm the toxicity of receipts.
