Background Plastic contamination is one of the concerns of our age. With more than 150 million tons of plastic floating in the oceans, and a further 8 million tons arriving to the water each year, in recent times the scientific community has been studying the effects these plastics have on sea life both in the field and with experimental approaches. Laboratory based studies have been using both natural sea water and artificial sea water for testing various aspects of plastic contamination, including the study of chemicals leached from the plastic particles to the water.

Plastic pollution has become one of the most serious environmental issues worldwide. Plastics can contain high amount of additives (e.g., phthalate, bisphenol A, trace metals), and they could be leached out of plastics, enter the aquatic environment and cause toxic effects to aquatic organisms (including microcrustacean). In this study, we investigated chronic effects of plastic leachates from two popular plastic materials (garbage bag and disposable raincoat) on the survival, maturation and reproduction of the microcrustcean Daphnia magna.

The broad use of plastics and the persistence of the material results in plastic residues being found practically everywhere in the environment. If plastics remain in the (aquatic) environment, natural weathering leads to degradation processes and compounds may leach from plastic into the environment. To investigate the impact of degradation process on toxicity of leachates, different types of UV irradiation (UV-C, UV-A/B) were used to simulate weathering processes of different plastic material containing virgin as well as recyclate material and biodegradable polymers.

Plastic consumables, used universally in bioscience laboratories, are presumed inert with respect to bioassay outcomes. However, it is clear that many pipette tips, microfuge tubes, and other plastic disposables leach bioactive compounds into assay solutions, profoundly affecting data and experimental interpretation. In this paper we discuss the nature and sources of leachates and review several examples of compromised bioassay data that speak to the probable widespread nature of this largely unrecognised source of error. Strategies for minimizing leachate interferences are discussed.

Polyethylene terephthalate (PET) is one of the most frequently used synthetic polymers and it plays a major role in plastic pollution in aquatic environments. As PET undergoes environmental degradation, it sheds microplastics and chemical leachates, which have an effect on microbial communities, including benthic cyanobacteria. This review focuses on the molecular processes by which PET microplastics and their associated leachate affect the growth, physiological performance, and ecological performance of benthic cyanobacteria. We explore how PET-derived compounds serve as carbon and energy sou

Different methods were used for determining mechanical properties, while ecotoxicity tests with two types of plants were performed for the assessment of the ecotoxicological potential of mortars. Results of strength tests revealed that PET in mortars increased 28-day compressive strength by up to 3% and decreased flexural strength by up to 14% compared to conventional mor

Mikroplaster definieras ofta som plastpartiklar mindre än fem millimeter och kan härstamma från olika mänskliga aktiviteter. Majoriteten av all plast som har producerats finns idag i deponier eller i naturen. Eftersom flera studier funnit att plastadditiver lakas ut ur deponier tros lakvatten från deponier vara en potentiell källa till mikroplastutsläpp. I denna studie undersöktes förekomsten av mikroplaster ≥ 100 mikrometer i beh

Plastic contamination has become a major scientific and societal concern. While research on this issue has been flourishing over the last decade, several aspects remain insufficiently explored, including the chemical impact of plastic leachates (i.e., a complex mix of chemical compounds released by plastic particles). Furthermore, essential biological factors, such as the reproductive cycle and sex, are still largely overlooked, particularly in marine invertebrates, further limiting our ability to fully assess the ecotoxicological risks posed by pollutants.

Abstract Radioactive wastes containing Iodine-129 are to be disposed of in Japan in an underground facility together with TRU wastes. Iodine-129 has a long half-life (1.6 × 107 y) and it is strongly adsorbed in the thyroid gland when it intrudes into the human body. The main chemical formulae of iodine in an alkaline solution are I− and IO3−, and these anion species are absorbed only to a very small extent on silicate minerals. Iodine-129, therefore, is one of the key nuclides to be studied in the geological disposal of radioactive wastes. Recently, a new inorganic ion-exchanger, BiPbO2NO3, ha
