The widespread presence of microplastics in the ocean is a significant threat to marine life and humans. A study was conducted investigate extent microplastic contamination coastal waters Langkawi Penang, situated on northern coast Peninsular Malaysia. Rock oysters ( Saccostrea cucullata ) were utilized as bioindicators due its availability all sampling sites evaluate microplastics,by considering abundance, types, polymer composition, potential health risks related consumption. Soft tissues digested with 10% KOH, resulting examined using stereo microscope identified through ATR-FTIR. Kok Beach Penarak exhibited notably higher mainly form filaments predominant black red colours. most common types cellulose triacetate (CTA) polycyclohexanedimethylene terephthalate (PCT).

First evidence of microplastic pollution in mangrove sediments and its ingestion by coral reef fish: Case study in Biawak Island, Indonesia

Open Agriculture, Год журнала: 2024, Номер 9(1)

Опубликована: Янв. 1, 2024

Abstract Introduction Microplastics (MPs) have emerged as one of the global principal marine environmental problems in many countries, including Indonesia. However, fewer studies been conducted on MP impact aquatic organisms. Thus, present case study aimed to investigate presence MPs mangrove sediments and coral reef fish Biawak Island, West Java, Materials methods The used a which samples were collected at specific locations time. Fish (15 individuals three family taxa) from sampling stations (A, B, C) Java Province, Indonesia, February 2023. types numbers investigated under monocular microscope. Results found all digestive tract fish. In sediments, abundances recorded 1,422 particles kg −1 dw sediment station A, 1,185 59.8 C. tracts 726.17 827.99 1670.42 Conclusion contaminated with higher areas greater coverage. Also, families ingesting MPs, Lutjanidae was identified largest amount their tract.

South Konawe Regency experienced a decrease in water supply and an increase demand, due the changes land use caused by ongoing exploitation, which increases runoff decreases infiltration capacity. As result, more is lost to ocean, threatening from Laeya River. River raw not only utilized for PDAM sources, but also used meet domestic needs of community, agricultural irrigation plantations, so it important know its sustainability status. This research aims carrying out activities that control quality River, as well serve information regarding status model management, raise environmental awareness. study was carried Regency.

Pollution that occurs in lake waters needs special attention from various parties the management of future. The activities occurring around result an increased inflow pollution into lake. aim this study is to assess condition Lake Aneuk Laot Sabang by utilizing indicators such as index, CCME WQI (Canadian Council Ministers Environment Water Quality Index), and saprobic index. investigation took place both September 2019 June 2021, employing stratified random sampling method with four designated observation stations for process. Parameter measurements analyzed index include temperature, depth, current, TDS, TSS, BOD, COD, DO, phosphate, nitrate, ammonia, sulfide, iron, lead, oil fat, detergent, pH, e-coliform, parameters used phytoplankton data. Based on analysis Index it determined status heavily polluted Class I, moderately Classes 1 2, falls under good category 4. results show beta-mesosaprobic a 2.3 (moderately loaded).
