Initial Analysis of Plastic Debris Accumulation in the Estuary of Wonorejo River, Surabaya, Indonesia
AI summary Read the abstract
Researchers investigated the accumulation of plastic debris in the intertidal zone of the Wonorejo River estuary in Surabaya, Indonesia, finding that the amount of plastic varied significantly between sampling stations. Statistical analysis showed that proximity to human settlement was a key factor in debris accumulation. The study provides baseline data on plastic pollution in an Indonesian urban estuary.
The purpose of this research was to investigate the accumulation of plastic debris in the Wonorejo River Estuary, Surabaya, Indonesia. Visible plastic debris were collected from three (3) sampling points along the intertidal area of Wonorejo River Estuary. The correlation between sampling points (SPs) and the amount of the collected plastic debris (CPD) was analysed using one-way ANOVA. Result of one-way ANOVA showed that the sampling point was significantly affect the amount of the collected plastic debris (p<0.05). A further analysis using Tukey’s Significance Honest Test indicating a significantly higher CPD on SP2 compared to the SP1 and SP3 ( p <0.05). The amount of CPD were 126.07±12.00 g dry weight/m 2 from SP1, 375.97±16.72 g dry weight/m 2 from SP2, and 291.13±36.28 g dry weight/m 2 from SP3. The highest percentage of collected debris item was plastic bags (up to 57.90%), followed by bottle caps (up to 16.65%). The most identified plastic types were Low-Density Polyethylene (LDPE) (up to 73.13%), followed by Polypropylene (PP) (up to 17.22%). Understanding the accumulation of plastic debris in estuary is a fundamental requirement to conduct an advance research related to the marine plastic pollution and to determine further actions to solve this problem.

Microplastic abundance in Surabaya mangrove areas during the wet season
AI summary Read the abstract
Researchers assessed microplastic abundance in water and sediment samples from Wonorejo mangrove areas in Surabaya, Indonesia during the wet season in December 2021, examining both high-tide water samples and low-tide sediment samples to characterize microplastic accumulation in this urban mangrove ecosystem. The study provided wet-season baseline data on microplastic pollution in a mangrove system known to trap suspended particles and debris.

Microplastic occurrence and distribution were characterized for the first time in sediments from 16 sites along urban and mangrove coastal areas of East Surabaya, Indonesia. Microplastic abundances ranged from undetected to 598 items per kilogram, with higher contamination in urban areas and characteristics reflecting mixed local plastic waste sources.
