Tell us what the water concern in your country is!There are many different problems surrounding water questions in Sweden. For example the water concern that our project researched was whether aquatic organisms were affected by receipts.
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.
