Environmental Pollution, Journal Year: 2024, Volume and Issue: 361, P. 124863 - 124863

The weight of marine litter has been marginally considered in comparison to counting and categorizing items. However, determines dynamics on water coasts, it is an essential parameter for planning optimizing clean-up activities. This work reviewed 80 publications that reported both the number beached macro-litter worldwide. On average, a item weighed 19.5 ± 20.3 g, with median 13.4 g. Plastics composed 80% by 51% global bulk. A plastic 12.9 13.8 g 9 analysis based continents bodies returned similar values, which can be used estimate beaches from past future visual census surveys, remote sensing imagery. Overall, this improve monitoring reports support modelling, thereby contributing environmental protection mitigation efforts.

Spatiotemporal variation in marine litter distribution along the Bulgarian Black Sea sandy beaches: amount, composition, plastic pollution, and cleanliness evaluation

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: June 18, 2024

The threat of anthropogenic marine litter, particularly plastic pollution, to ecosystems and human health, has spurred mitigation initiatives global scientific research. Following the Marine Strategy Framework Directive guidelines, this study evaluated litter distribution, cleanliness, pollution indices along Bulgarian Black Sea beaches in 2023. survey integrates visual assessment, manual sampling, drone mapping, distributing coastline encompass a broader range, totaling 45, including 28 remote/natural, 10 semi-urban, 7 urban beaches. Results indicate 48% decrease distribution on from 1462 ± 147 items/100 m 2021 753 97 2023, with Artificial polymer materials/plastic materials constituting 88.62% total amount. A comprehensive macro assessment was carried out using PAI for first time. In average cleanliness status classified as “ moderate ” (CCI: 7.61 1.00), clean northern central contrasting dirty southern Urbanized were assessed highest level (PAI AV,23 : 5.51; CCI 18.16). long term, maintain values AV,18-23 8.81 0.89, 2.35 0.32, persisting throughout period, necessitating ongoing monitoring intervention strategies. Despite identifying significant number beaches, none meet EU threshold value 20 m. This highlights urgent need effective interventions combat accumulation or semi-urban emphasizing multi-stakeholder collaboration sustainable solutions coastal ecosystem preservation.

A baseline assessment of anthropogenic macrolitter on dunes along the Bulgarian Black Sea Coast using visual census and Unmanned Aerial Systems

Beach-dune systems are among the most dynamic and sensitive elements of coastal ecosystems in world. They represent an intersection between human activities, flora, fauna economic interests tourism. The Bulgarian Black Sea shoreline spans 518.7 km comprises 131 (25%) depositional coast, including beaches 46 dune systems. Over past three decades, heavy anthropogenic impacts have been observed, significantly altering cleanliness beach-dune along Coast (BBSC). research initially began as initial assessment macrolitter on dunes (MLD) using Unmanned Aerial Systems (UAS). However, due to concerning data obtained first year, it transitioned into a mid-term monitoring program conducted 2018 2022. baseline is based visual census, UAS mapping manual image screening procedure GIS environment for litter 40 areas (ALMs) Coast. Throughout five-year period, abundant type MLD was “Artificial polymer materials,” accounting 83.4% total number, followed by “Paper/Cardboard” (6.2%), “Glass/Ceramics” (2.8%), “Metal” “Processed/Worked wood” (1.83%), “Rubber” (1.29%), “Cloth/Textile” (1.17%). Generally, 95% amount assessed from Land-based sources 5% Sea-based sources. COVID-19 pandemic indirectly affected restrictions foreign travel, which increased domestic tourist pressure beaches, resulting more significant waste accumulating dunes. abundance experienced increase 39% 2021.

Abstract Plastic and marine litter is one of the current growing issues worldwide, affecting unique Black Sea ecosystem as well. Litter yearly monitored for assessing ecological status across Romanian beaches. We tested aerial drone-inspection or UAV method versus visual census efficiency monitoring on two beaches, located in Danube Delta area. The detection probability varied between size-category items, with 71 – 100% accuracy screening drone images. Our pilot study showed successful combination traditional new emerging techniques selected areas. To best our knowledge, this first evaluating fast-screening not-easily accessible sites at coast Sea.
