“…In the analysis of the HMs fractions, the mild acido-soluble and oxidizable fractions accounted for most of the total HM concentrations, contributing 16.77–51.60% and 18.40–57.90% of the total HM concentrations, respectively (Figure S3). This is mainly attributed to the adsorption of HMs in the organic components of the biofilm. , However, the reducible and residual fractions of HMs on the MPs respectively account for 4.49–26.77% and 1.36–29.85% of the total HM concentration, which can be attributed to the binding of minerals to HMs on the MPs. As the exposure time of the MPs to the ocean increases, a large number of natural minerals are intercepted on the MPs, resulting in the coadsorption of HMs that are fixed onto the minerals .…”

The insufficient control of waste associated with personal protective equipment (PPE) resulted in a large influx of disposable face masks (DFMs) in marine environments. Herein, we investigated the biofilm colonization on three types of polypropylene microplastics (MPs, i.e., DFMs, films, and particles) as well as the potential risks of MP-associated heavy metals (HMs) in seawater. Compared to conventional MP particles and films, DFMs were conducive to colonization by microorganisms and minerals, resulting in the formation of a typical spatial network biofilm structure. This triggered more HM adsorption by the biofilm-developed DFMs through surface complexation with the organic components in the biofilm. By BCR sequential extraction analysis, we found that organic and mineral components comprised 70.2−85.6% and 14.4−29.8% of the HM concentration in the biofilm-developed DFMs, respectively. In an in vitro gastrointestinal tract model, biofilm-developed DFMs had a much higher desorption capacity for HMs than MP particles and films. Moreover, the ecological risk index of biofilm-developed DFMs was significantly higher than that of biofilm-developed films and particles. Considering the potential ecological risk of biofilm-developed DFMs, we advocate that the reasonable recycling and environmentally friendly treatment of PPE MP pollutants should be considered as a bursting challenge for sustainable coastal development.

“…Wijaya, et al (2020) reported that the anthropogenic activities that occur around the waters of Prigi Bay result in many inactive corals on the coast [4]. These inactive corals become coral skeleton waste known as coral skeletons [5]- [7], as well as analytical methods to identify heavy metal isotope ratios [8], [9]. The abundance of coral skeletons on the shoreline of Prigi Beach contains an abundant calcium up to 90% in the form of CaCO3.…”

The calcium-alginate-silica demonstrates the potential application of a membrane for clean water supply through the absorption of Cl- and Na+ ions. Calcium originated from coral skeletons, while silica was extracted from the beach sands of The Gulf of Prigi. The produced membrane was characterized using XRF, FTIR, and SEM techniques, followed by NaCl solution adsorption studies. The results show that the coral skeletons as source of Ca consist mainly of calcium oxide based on XRF analysis, ranging from 90.86% to 93.41%. Similarly, Si in the beach sands primarily consist of SiO2, ranging from 16.2% to 89.5%. FTIR analysis indicates the presence of functional groups (-OH, C=O, C-O, Si-O, and Si-OH) that facilitate the NaCl adsorption process. Additionally, SEM analysis was conducted using ImageJ, showing a particle size diameter of 16192.78 nm, which was characterized by a porous and relatively coarse structural morphology. The calcium-alginate-silica membrane showed the Na+ and Cl- ion adsorptions of 55.4% and 49.4% at the optimal contact time of 20 and 40 minutes, respectively.
