Purpose Plastic pollution in the world has led to an abundance of microplastics (MPs) and has been identified as a potential factor that can lead to serious environmental problems, especially in oceans and seas. Information on the current status of MPs pollution along the Montenegrin coast is insufficiently investigated. This study monitors the abundance, distribution, and sources of MPs, and identifies present polymers in the surface sediment of the Montenegrin coast, as well as comparison with previous research. Materials and methods Ten sampling sites along the Montenegrin coast were selected to collect surface sediment samples. The upper layer of sediment (0–5 cm) was collected by a Petite ponar grab. The samples were dried, and density separation was performed using a NaCl solution. The abundance and morphological characteristics of MPs were determined using an optical microscope (DP-Soft software), while FT-IR analysis was done to identify the polymer type. Results and discussion Microplastics were identified in all sediment samples with an average abundance of 307 ± 133 (SD) MPs/kg in dry sediment. The highest abundance of MPs was found in locations in the vicinity of highly populated areas, near wastewater discharges, and areas with high fishing and tourist activities. The most dominant shape types of MPs in all samples were filaments and fragments. The most common colors of MPs were blue and red, while the dominant MPs sizes were 0.1–0.5 mm and 0.5–1.0 mm. Of the eight identified polymers, PP, PE, and PET were the most common. Conclusion This study reveals MPs characteristics (abundance, distribution, shape type, colors, size, polymers type) in surface sediment along the Montenegrin coast, as well as the most significant sources of MPs pollution, and provides important data for further research on MPs to identify the effects of MPs pollution on the quality, health, and functionality of the marine environment.

Considering that microplastics are widespread in the marine environment, in this study we evaluated the presence, identify distribution, abundance, shape type, and color of microplastics in surface sediment along the Montenegrin coast, on the Adriatic Sea. These preliminary results provide the first published record of microplastics found in the surface sediment of this area and highlight the importance of microplastics as a component of marine debris. We documented the presence of microplastics at all sampling locations. The identification of polymer types was performed using Fourier-transform infrared (FTIR) spectroscopy, whereby the presence of three polymer types became evident: polypropylene (54.5%), polyethylene (9.7%), and acrylate copolymer (2.0%). Another 22.2% of particles were unidentified polymers, and the remaining 11.5% were non-synthetic materials. The most common shape type of microplastics was filaments (55.5%), followed by granules (26.3%), fragments (14.9%), and films (3.3%). The dominant colors of microplastics followed the order: blue > yellow > red > clear > black > green > blue-white > white. The average abundance of microplastics in all sampling locations was 609 pieces of microplastic/kg of dry sediment. Compared with other studies, the surface sediment of the Montenegrin coast is moderately to highly polluted with microplastics, depending on the examined location.

“…This is due to the fact that the metal ion in the basic medium forms gelatinous compounds that precipitate In the form of metal hydroxides, but in the acidic medium, metal ions separate from the surface of the adsorbent material, and this leads to a decrease in the value of (Q) and the reason for this decrease is the competition between hydrogen ions, which increases with the increase in acidity and metal ions in the solution, for the binding sites in polyhydroxamic acid present in the polymer and this leads to a decrease in the adsorption capacity with an increase in acidity [19] , as shown table (5,6) -fig (8,9) Measuring temperature of adsorption of Metal Ions' PHA : as shown table (9,10) the studied ion adsorption heat values before and after adding nano carbon, the temperature of adsorption (He) is calculated using the Clausius-Clapeyron equation for chemical adsorption . It is possible to measure the adsorption temperature as an equilibrium process by obtaining the value of the adsorption capacity for metallic ions at various temperature degrees, for example, (T1 and T2), and obtaining the (Ce1, C e2) for achieving the same breakage that is related to the covered surface by using the equation below [20]…”

The research includes, the preparation of Polymer methyl methacrylate by free radical polymerization at a temperature of (70-80oC) and using the initiator benzoyl peroxide with a conversion rate of 10%.Then characterize the resulting polymer using infrared spectroscopy (FT-IR) and nuclear magnetic resonance spectroscopy (HNMR). The ester group in the resulting methyl metha acrylate polymer was converted to poly hydroxamic acid by neutralizing the polymer with hydroxyl amine hydro chloride in a base medium pH = 12-13 using potassium hydroxide with thermal escalation 120 hours, the resulting compound was diagnosed by infrared spectroscopy. A certain amount of nano carbon was added to the same amount of poly hydroxamic acid and mixed well. The adsorption capacity of poly(methyl metha acrylate) hydroxamic acid was determined for the ferric and ferrous ions before and after adding nano carbon to poly hydroxaic acid. The factors that affect the adsorption capacity such as time, acidity function and temperature were studied, Where the adsorption capacity increases with increasing time, and the highest adsorption capacity is at pH = 6, where the adsorption rate decreases when the acidity increases and decreases from pH equal six, as well as the heat of adsorption was calcution at two different temperatures.
