“…A significantly elevated cumulative duration of low mobility (DLM) was also detected in medaka in the TBT-10 group ( Figure 1 D). Depending on the changing relative to the two defined thresholds of mobility [ 33 , 34 ], the locomotor activity of medaka was divided into three states (i.e., high mobility, >60%; moderate mobility, 20–60%; low mobility, <20%). Thus, the above behavioral responses suggested that oral exposure to TBT at a level of 10 ng/g-bw/d could induce hypoactivity in medaka.…”

The widely used compound tributyltin (TBT), which can be continuously detected in aquatic species and seafood, may induce diverse adverse effects on aquatic organisms. However, little is known regarding the mechanistic links between behavioral abnormality and oxidative stress in different fish tissues in response to oral TBT exposure. Herein, juvenile Japanese medaka (Oryzias latipes) were orally exposed to TBT at 1 and 10 ng/g-bw/d for four weeks. After exposure, the locomotor activity and social interaction of juvenile medaka were found to be significantly reduced in the 10 ng/g-bw/d TBT-exposed group. Furthermore, the antioxidant biomarkers in different tissues of juvenile medaka showed different levels of sensitivity to TBT exposure. The eye superoxide dismutase (SOD) activities markedly increased in both groups exposed to 1 and 10 ng/g-bw/d TBT, while the eye and brain malondialdehyde (MDA) levels increased in the higher dose group. Furthermore, the eye and brain ATPase activities markedly declined in the 1 ng/g-bw/d TBT-exposed group. A correlation analysis revealed that the decreased locomotor activity and social interaction in medaka were associated with the eye antioxidant enzyme (i.e., SOD and catalase (CAT)) activity and brain oxidative damage level. Thus, our findings suggested that there might be some mechanistic links between the behavioral abnormality induced by TBT exposure and oxidative stress in the eyes and brains of medaka. Thus, our findings indicate that the impacts of oral exposure to TBT should be considered to better assess its risk to the aquatic ecosystem and human health.

“…After a 10 min acclimation period, fish locomotion was tracked for 10 min using a Danio Vision system (Noldus, Wageningen, The Netherlands) and analyzed using the EthoVision XT software (Vison 11.5; Noldus). Parameters representing behavioral traits were measured and calculated according to the descriptions provided by Qiu et al [ 33 ].…”

“…Microplastics deposited at the bottom of water, such as rivers, were easily swallowed and absorbed by aquatic animals and then circulated in the food chain superposition step by step. As a result, bioaccumulation was constantly amplified [31], such as microplastics used as anthracene carriers in medaka [32] and polyvinyl chloride (PVC) used as carriers of heavy metals [33]. Some contaminants also exhibited competitive behavior on the surface of microplastics, as DDT interferes with the adsorption of phenylalanine plastics [34].…”

The studies on microplastics are significant in the world. According to the literature, microplastics have greatly specific surface areas, indicating high adsorption capacities for highly toxic pollutants in aquatic and soil environments, and these could be used as adsorbents. The influencing factors of microplastic adsorption, classification of microplastics, and adsorption mechanisms using microplastics for adsorbing organic, inorganic, and mixed pollutants are summarized in the paper. Furthermore, the influence of pH, temperature, functional groups, aging, and other factors related to the adsorption performances of plastics are discussed in detail. We found that microplastics have greater advantages in efficient adsorption performance and cost-effectiveness. In this paper, the adsorptions of pollutants by microplastics and their performance is proposed, which provides significant guidance for future research in this field.

“…As a matter of fact, microplastics can absorb surrounding persistent organic pollutants (POPs) and/or heavy metals, and serve as attachment media for microorganisms. Thus, microplastics may act as vectors for lipophilic toxic chemicals and microbial pathogens to organisms (Koelmans et al 2016;Besseling et al 2019;Hildebrandt et al 2020;Nobre et al 2020;Qiu et al 2020;Sharma et al 2020). Of similar relevance is that microplastics release toxic additives contained in almost all plastic materials.…”

“…It is worth noting that these compounds have been classified by the International Agency for Research on Cancer (IARC) as Group 1 carcinogens. It has, therefore, been hypothesized that ingestion of microplastics by aquatic biota increases the bioaccumulation of anthropogenic pollutants (Nobre et al 2020;Qiu et al 2020;Sharma et al 2020;Pandey et al 2021). Microplastics may further serve as transport vehicles for POPs between different contamination areas (Wang et al 2020).…”

From 2004 to 2017 he was a member and chair of the Committee of Directors. He is a fisheries biologist trained at Bochum, Hamburg and Kiel University and has worked in Antarctica, Argentina, and the Azores. Since 1991 his work has revolved around fish biology and ecology in tropical ecosystems and throughout the 1990s he was a coordinator for the bilateral co-operation in Marine Research between Brazil and Germany. His research interests lie in the wider field of "Adaptations of different life stages of fish to their environment and the consequences of climate change". This includes activities in growth and population dynamics; migration pattern of fish in coastal environments; ichthyoplankton; fisheries biology; ecology; and ecosystem responses to climate change. An important topic is his work is the ecosystem approach to fisheries management, by which he engaged for many years in the Large Marine Ecosystem community as well as the stimulation and enforcement of international cooperation and networking in marine science and governance. He is a member of the Group of Experts on Capacity Development of the Intergovernmental Oceanographic Commission of UNESCO.
