Abstract

Highlight Research Brown seaweed heavy metals content varies between species Risk assessment showed low health risk for heavy metal from intake of the three brown seaweed The three types of brown seaweed did not show carcinogenic properties to metal Arsenic (As) Abstract Marine brown seaweed are known as one of the potential biological agents to be developed as functional food and medicinal sectors. This study aims to examine the concentration of heavy metals (Pb, Cd, Hg, and As) in brown algae (Sargassum aquifolium, Padina australis, and Turbinaria ornata.) and the possible exposure to health risks caused by consumption.  Heavy metal concentrations were determined using Atomic Absorption Spectroscopy (AAS) on brown seaweed samples obtained from three different sites. The average concentration of heavy metals in the dry weight of brown seaweed remains within the guidelines established by The Food and Drug Supervisory Agency (BPOM) Number 32 of 2019 concerning the Safety and Quality of Traditional Medicines, which is then used to calculate the estimated daily intake (EDI), target hazard quotient (THQ and TTHQ), and target cancer risk (TCR) for arsenic associated with food exposure to potentially toxic metallic elements. Each species of brown seaweed has a THQ and TTHQ level of <1, indicating that one or more toxic metal elements in the same meal provide no significant non-carcinogenic risk. The TCR for arsenic in these seaweeds are all less than 1 x 10-4, indicating no cancer risk. There are no chronic health hazards related with the ingestion of brown seaweed harvested from the coast of Sanur Beach at Denpasar, Bali.

Abstract

This study aimed to analyze Microplastics (MPs) contamination in brown algae and sediments, and their bioaccumulation factors, and estimate the risk to human health associated with exposure to ingested MPs collected from the water of the Sanur Beach, Bali Province. The samples were collected from three beaches which were determined using a purposive sampling method. The mean number of MPs found in P. australis was the same on all beaches, namely 17 items/seaweed, higher than S. aquifolium on all beaches. Line-shaped MPs were dominantly found in all algae (98.76%). A high percentage of line-shaped MPs was   found in sediments at Mertasari and Semawang Beaches, but not at Sindhu Beach. The highest mean size of MPs in algae was found in P. australis at Semawang Beach, and sediments at Mertasari beach. The highest concentrations of MPs were also found in P. australis on the three coasts. The BAF value showed that the absorption of MPs in the sediment to brown algae was still low (<1). Values related to intake of brown algae consumption ranged from 190.58-1429.41 MPs item/week adjusted for calculation recommendations.

Abstract

This study focus on calculating the carbon footprint from the activities of the Universitas Airlangga. CO2 emission calculations were carried out using the UI GreenMetric method and the Intergovernmental Panel on Climate Change (IPCC) in two periods: before the Covid-19 pandemic and during the Covid-19 pandemic. Activities at Universitas Airlangga that produce carbon footprints are divided into two main sources, first, primary sources that come from direct combustion of fuel into energy, such as burning fuel in motorized vehicles and a secondary source that comes from an indirect source of using electricity in the campus area. The results showed that in the period before the pandemic, the total carbon emissions, based on the IPCC calculation method, were 23.830,34 tons of CO2-eq/year. Meanwhile, based on the UI GreenMetric method, a total carbon emission of 26.325,36 tons of CO2-eq/year was obtained. As for the time period during the pandemic, Universitas Airlangga's total carbon emissions obtained based on the IPCC calculation method were 20.506,69 tons of CO2-eq/year. Meanwhile, based on the UI GreenMetric method, a total carbon emission of 22.321,63 tons of CO2-eq/year was obtained. Secondary carbon footprint mapping is carried out to ascertain the distribution of secondary CO2 emissions produced by Universitas Airlangga. The secondary carbon footprint both before and during the Covid-19 pandemic was mostly generated by the Universitas Airlangga Hospital.

Abstract

Microplastics (MPs) are pollutant agents that have been absorbed and detected in aquatic ecosystems at high concentrations. This study aimed to investigate the presence of MPs pollution in green mussel (Perna viridis) products sold at the Kedonganan fish market, Badung, Bali. A total of 150 mussels with an average weight of 3,2 ± 0,71 g/mussels from three traders each composed and followed by the pre-treatment stage using 5 M NaCl solution, extraction with wet oxidation peroxidation (WPO) + Fe(II) catalyst and filtered. The highest percentage for the form of MPs was successively obtained by the Line form in Trader A at 85,42% and the lowest in Trader C at 50,00%. The highest form of fragments was obtained in Trader C at 42,86%. Film and filament forms were only obtained in Trader A. The highest MPs color was black and the lowest was gray. The highest average MPs particle size was found in the form of a filament of 1944,37 ± 88,41 μm which was found in Trader A. Estimates of MPs intake per year/capita in Indonesia showed that exposure to MPs through consumption of green mussels in this study amounted to 498,330 MPs/year/capita items. Overall, the green mussel from Trader A had the highest percentage and size of MPs, with the shape of fragment MPs being dominated by Trader C and the color of the MPs being dominated by black. MPs exposure to green mussel consumption in Indonesia is very high, but no health impact category has yet been found for this estimate.

Abstract

This research attempted to determine the abundance and characteristics, including morphology, color, and size of microplastics found in coastal sediment and seawater of Wonorejo, Surabaya, which is located on the north coast of East Java, and Popoh, Tulungagung on the south coast of East Java. Water and sediment samples were collected during the dry season with two replications. The standard method of water sample laboratory preparation and microplastic identification was carried out using NOAA Technical Memorandum NOS-OR&R-48, while the sediment sample was prepared with several modifications. The average microplastic abundance in Surabaya and Tulungagung seawater samples is equal to 2100 particles m-3 and 170 particles m-3, respectively. Meanwhile, as many as 740 particles kg-1 and 350 particles kg-1 were found consecutively in sediment samples of Surabaya and Tulungagung. Microplastics in seawater samples were dominated by 44.7% red and 80.9% fiber, while 43.1% black and 51.4% fiber microplastics were primarily found in sediment samples. The microplastic size ranges from 30—1450 μm in seawater samples and 50—3750 μm in sediment samples. Keywords: abundance, characteristics, microplastics, seawater, sediment.

Abstract

The island of Bali has become a popular tourist destination, but its impact on the coastal environment, particularly Serangan Beach in Bali is highly neglected. The method used in this research is a literature study of the distribution of microplastic and microplastic waste found on the coast of Serangan Beach Bali, through digital literacy journals such as Google Scholar, Science Mago and Science Direct. Based on some of these journals, it was found that micrometals pollutants, and microplastics that are not cleaned up can cause pollution of the flora and fauna ecosystem of Serangan Beach Bali. Although the impact of micrometals and microplastics in the present is not great, it will have a great impact in the future if there is no proper effort to overcome it.. This investigation is important to provide a better understanding of the impacts of micrometals and microplastic pollution on Bali's coastal ecosystems and to inform more effective environmental policies and management actions to protect and maintain marine resources critical to environmental sustainability and human well-being.
