Megjegyzések:	Fish scales absorb different elements into the calcified matrix from surrounding waters as well as from the foods consumed. Scales microchemistry is drawing rising attention for its applicability in a wide range of fields, including environmental and ecological studies. The article represents an elemental analysis of the scales of five commercially important coastal fishes: Tenualosa ilisha, Sillaginopsis panijus, Lates calcarifer, Otolithoides pama, and Rhinomugil corsula. The concentrations of different essential and trace elements were measured using inductively coupled plasma optical emission spectrometry (ICP-OES), and their distribution on scales was mapped using micro-X-ray fluorescence (?-XRF). The detected elements were categorized into five groups based on their overall mean concentrations: the most, considerable, moderate, low, and least available. The concentration (mg kg?1) of Ca was the highest (107472.32-181002.76) followed by P (41572.43-79042.02) among the elements in the studied fish scales, independent of species. The hierarchy of the overall mean concentration of elements was Ca>P>S>Mg>Na>K>Sr>Zn>Fe>Al>Ba>Mn>Cu>Cr. Element concentrations varied across fish feeding habits and habitats. Carnivore fish were found to have higher concentrations of K, Sr, and lower Fe than that in planktivore fish. The concentrations of Cr, Fe, S, Sr, and Zn were higher in demersal fish's scales, whereas pelagic fish were found to have higher levels of Al, Ba, Ca, Cu, K, Mg, Mn, Na, and P. Element: Ca ratios, especially Sr: Ca, Mn: Ca, and Ba: Ca ratios, have potential implications as habitat signatures. Typically, fish otoliths are used for environmental and ecological purposes that involve cutting and sacrificing the sample. Employing scales instead could be a non-lethal alternative, crucial for sustainable fisheries management, especially for rare, vulnerable, or migratory fish.

Cím:	Accumulation of Microplastics and Potentially Toxic Elements in Plant Leaves Along an Urbanization Gradient in Bangladesh / Md Sohel Parvez, Herta Czédli, Imdadul Hoque, Mohammad Mizanur Rahman, Armin Anwar, Abu Hena Mohammad Mezbah Uddin, Siddiq Hasan, Dina Bibi, Béla Tóthmérész, Tibor Magura, Edina Simon

Megjegyzések:	Potentially toxic elements (PTEs) and microplastics (MPs) in the atmosphere raise widespread apprehension due to their association with the ecosystem and public health. The accumulation of airborne MPs and PTEs was analyzed in Polyalthia longifolia leaves, and the Pollution Index (PI) was calculated along an industrial, residential, and rural gradient in Bangladesh. Only polyethylene terephthalate (PET) was found in the highest concentration in industrial areas compared to other areas. In leaves, a significantly higher Cd, Pb, and Zn concentration was found in industrial regions compared to residential and rural areas. For Cd, the PI was observed to be higher than 1 in rural areas, indicating a moderate level of pollution; it was higher than 3 in residential areas, showing considerable pollution; and it was found to be more than 6 in industrial areas. The higher concentration of both MPs and PTEs with increasing urbanization reflects the influence of anthropogenic activities. The findings of the study demonstrate the fascinating potential of P. longifolia tree leaves as a promising bioindicator for air quality biomonitoring.
