“…They indicate that the phosphorus content in Cystoseira increased (R 2 =0.617, figure 2C) and the accumulation factors decreased (figure 2D) with an increase of the phosphorus concentration in water. The linear correlation between the accumulation coefficients and PO 4 concentration in water in logarithmic coordinates (figure 2D) showed with some certainty (R 2 =0.348) that it can be described with a power-law function that corresponds to the modified Freundlich equation [15].…”

The goal of this study was to assess the role of Cystoseira phytocenosis as a biochemical barrier to the phosphorus detrophication through the phytoplankton primary production in waters of the specially protected natural area (SPNA) “Cape Martyan” on the southern coast of Crimea. We present data on the mineral phosphorus concentration in seawater and in the brown algae Cystoseira (Cystoseira s.l.) phytocenosis in 2021 and the phytoplankton primary production in 2017 – 2019. In the SPNA sublittoral zone, wet weight of the Cystoseira phytocenosis was estimated at 1425.6 tons, the production 3136.3 tons year–1, and the phosphorus accumulation factor 20,900 – 54,500. The phosphorus pool in the Cystoseira biotope ranged from 69.6 to 78.99% of that in the sublittoral zone and decreased with the phosphate concentration increase. The primary production in the SPNA sublittoral zone was mainly phosphate-limited. With the phosphate concentration increase, the primary production can reach hypereutrophication levels (100 mg Corg m–3 day–1). The phosphorus accumulation in the Cystoseira biotope reduced the phosphorus availability for the primary production to 10.4 – 30.4%. By the example of the SPNA “Cape Martyan”, we show that Cystoseira phytocenosis is a highly efficient barrier to the phosphorus detrophication in coastal waters.

The mussel M. galloprovincialis is one of the most popular species in world's mariculture and environment pollution bioindicators. Although this mollusk was in a focus of numerous publications, the detoxifying and accumulating role of some of its body parts was insu ciently studied. In the present work, using inductively coupled plasma mass spectrometry, the distribution of Cr, Co, Ni, Cu, Zn, As, Cd, Hg, Pb in soft tissues, byssus, and shell liquor of this bivalve was studied for the rst time as a function of sampling location in the Black Sea off southwestern Crimea. Multivariate analysis showed signi cant differences in the overall distribution of the elements among the body parts and sampling sites under consideration. Human health risks from the consumption of this mollusk were shown to be unlikely. Byssus of M. galloprovincialis was characterized as an ideal indicator of marine environment pollution with Ni, Cu, Pb, Сo, and Cr as it contained the highest contents of these elements among the body parts under study (Ni up to 91%, Cu and Pb up to 79%). For the rst time, the concentrations of trace elements were determined in the shell liquor and its role as the trace element excretion system was demonstrated. In the shell liquor, the largest share among the body parts was that of Hg (up to 71%). In soft tissues, Zn, Cd and As were in largest proportions among the body parts (63, 62, and 54%, respectively). The trace element contents in soft tissues of M. galloprovincialis decreased in the following order: Zn > Cu > As > Ni > Pb > Cd > Cr > Co > Hg.
