The shift to a green economy presents substantial barriers to sustainable economic growth. A key component of promoting a sustainable and green growth trajectory is educating the public about environmental sustainability, climate change, and the green economy. The main aim of this study is to evaluate students' understanding of green economy, and environmental concerns while highlighting the contribution of education to the green transition. The study was carried out in Kosovo using a quantitative method approach in a sample from 425 students including undergraduate, master and PhD. The analysis examined in this study are Multiple Regression Analysis, Pearson Correlations, Cronbach's Alpha, Inter item correlations, and descriptive statistics using IBM SPSS program Multiple Regression results showed that students' intention to continue their education in the green economy was significantly predicted by factors like comprehension of environmental policies, confidence in comprehending global economic challenges, and belief in the significance of government policies for the green transition. Significantly, students' willingness to participate in green economy studies was inversely connected with their comprehension of the role of law in environmental issues, indicating a possible discrepancy between perceived readiness and actual participation. The findings indicate that students possess a limited understanding of the green economy and environmental concerns in Kosovo; however, they are quite enthusiastic about expanding their knowledge, particularly via bachelor’s and master’s programs focused on these topics. Considering these results, the research proposes that to enhance awareness and preparedness for the green transition, new educational programs and vocational training efforts should be established alongside targeted conferences. These initiatives are crucial for providing professionals and students with the resources necessary for a sustainable future. Proper education can have a fundamental impact on environmental protection and sustainable economic development thus policymakers and universities must collaborate to create applicable study programs and curricula that promote a stronger focus on green and sustainable education.

Microplastics are widely present in aquatic environments and, due to their high hydrophobicity, can carry organic pollutants while affecting their accumulation and toxicity in organisms at different trophic levels. The ingestion of microplastics by organisms can be divided into direct and indirect ingestion. Direct ingestion refers to organisms directly consuming microplastics present in the environmental medium, while indirect ingestion can be understood as microplastics being ingested by organisms along the transfer of trophic levels. This study aimed to determine the distribution of microplastics in the surface water of the Yangtze River Estuary and the accumulation characteristics of microplastics in organisms at different trophic levels. In 2021, the study selected typical sampling stations in the Yangtze River Estuary and its adjacent waters for observation, analyzing the concentration and characteristics of microplastics in surface water and samples from nine different trophic level organisms (two types of gastropods and seven types of fish). The abundance of microplastics in the surface water samples collected from the Yangtze River Estuary was 661.2 ± 220.5 items/m$^3$. The average abundance of microplastics in the gills of organisms was 1.1 ± 0.4 items/g w.w., and in the gastrointestinal tract, it was 0.3 ± 0.1 items/g w.w. Based on the calculation of the bioconcentration factor of microplastics, we found that the bioconcentration factor of higher trophic level organisms (fish) (2.6 ± 0.5 m$^3$/kg w.w.) was significantly greater than that of gastropod organisms (0.87 ± 0.4 m$^3$/kg w.w.). In terms of feeding types, the bioconcentration factor of carnivorous fish organisms was significantly greater than that of omnivorous fish. This paper determined the trophic level of organisms through stable nitrogen isotopes ($\delta^{15}$N), and the biomagnification factor of microplastics was calculated to be 4.2 based on the linear regression equation of microplastic concentration and organism trophic level. Therefore, microplastic concentrations can be transferred along different trophic levels in the food chain, and the accumulation level of microplastics in organisms significantly increases with the rise of trophic levels, indicating the potential for biomagnification of microplastics in gastropods and fish organisms.
