October 2023
Marine debris accumulation and contamination have become escalating yet disastrous environmental impacts in marine ecosystems at present Sri Lanka context. Thus, we conducted this study to assess the marine debris abundance and density in randomly selected sites (n = 6) of Kandakuliya beach, Negombo, Sri Lanka. Marine debris density was used to explore the extent of beach pollution from marine debris.

- The study investigates sociocultural factors contributing to the rise of leptospirosis in rural Sri Lanka and their impact on health promotion efforts.
- Insights were gathered through interviews with public health officials and infected patients, revealing key themes such as lack of knowledge, misconceptions about the disease, and economic challenges.
- The findings underscore the importance of awareness programs to address misunderstandings around leptospirosis to improve community health interventions.
Article Synopsis
- The study highlights the severe impact of marine debris on mangrove ecosystems in Negombo lagoon, Sri Lanka, where approximately 9.83% of the substrate is covered by debris, primarily single-use plastics.
- Higher levels of debris were found at Kadolkele (18.80%) compared to Molekadolwetiya (0.85%), indicating significant pollution in these areas.
- The research demonstrates that marine debris correlates with physical damage to mangrove roots and seedlings, suggesting urgent need for remedial actions to reduce and remove debris to protect these crucial coastal habitats.
Global climate change scenarios such as frequent and extreme floods disturb the river basins by destructing the vegetation resulting in rehabilitation procedures being more costly. Thus, understanding the recovery and regeneration of vegetation followed by extreme flood events is critical for a successful rehabilitation process. Spatial and temporal variation of biochemical and biophysical features derived from remote sensing technology in vegetation can be incorporated to understand the recovery and regeneration of vegetation.

Therefore, this study aimed to screen synthetic polymers having MPs favoring chemical properties in PCCPs while estimating the theoretical emission into the environment and the level of awareness on the availability of MPs in PCCPs. A questionnaire survey was conducted via Google form using a complete random sampling method (n = 312).
