Solid waste composition and COVID-19-induced changes in an inland water ecosystem in Turkey

Abstract

The composition and abundance of solid waste and the effect of COVID-19 measures were studied in an inland water ecosystem in Turkey. Solid waste items were collected annually for 5 years from 2017 to 2021 from seven stations located in Borçka Dam Lake (B1–B4) and Murgul Stream (M1–M3) in the Artvin Province. The highest densities by number and weight were recorded at M3 in 2020 (5.72 items/m 2 ) and M1 in 2020 (0.39 kg/m 2 ), respectively. However, no significant difference in density was recorded ( p < 0.05) between the years. Plastic was the most abundant waste material by number of items in all the stations with a percentage contribution varying between 25.47 and 88.89%. There was a considerable increase in medical items during the COVID-19 pandemic in 2020–2021. Nonmetric multidimensional scaling (NMDS) and ANOSIM results revealed visually and statistically significant differences in solid waste composition between the years and stations. The dissimilarity between the years was driven by plastic and medical waste. The main sources of solid waste were river transportation (22.93%), improper disposal (20.74%), aquaculture activities (16.42%), and recreational and tourism activities (14.72%). The results of our study can be a baseline for transportation models, local administrations, and non-governmental organizations. Besides, the current waste management measures in Turkey are not effective in preventing waste accumulation in inland aquatic systems such as the Borçka Dam Lake and Murgul Stream. Furthermore, these findings indicate that the COVID-19 pandemic influenced solid waste composition and increased its abundance in the study area.

Disposable Face-Mask Waste Management and Assessment Through Willingness to Pay and SWOT Framework in Post COVID-19 Pandemic

“…Indonesia ranks first in producing plastic waste with a contribution of 17.46% [29]. A significant amount of mask waste is found in waterways, and it can cause water pollution [30,31]. This is because disposable mask waste contains chemical compounds that can interfere with polluting the environment [32] so that the existence of marine biota is threatened, even the diversity of plants in the sea is also threatened, and in the end all aspects of the environment are disturbed in balance, meaning that the disposal of mask waste by the community is not disposed of in its place.…”
