The level of activity of eight extracellular hydrolytic enzymes responsible for biodegradation of high molecular weight polymers in the water-sediment interface in the coastal river estuary was determined. The ranking order of the mean enzyme activity rates in the sediment-water interface was as follows: lipase > aminopeptidase > phosphatase > β-glucosidase > α-glucosidase > xylanase > chitinase > cellulase. The activity of the studied enzymes differed between various parts of the estuary. Each enzyme had its characteristic horizontal activity profile. Extracellular enzymatic activities were strongly influenced by the season. As a rule, tested enzymes showed their maximum hydrolytic activity during the vegetation period.

“…The sea-surface microlayer (SSM) is a single hydrated gelatinous layer at the air-sea interface, which has unique physical, chemical, and biological properties differing from surface water [113][114][115]. Total Cu was enriched by factors of 2.8 and 16 in the SSMs of Lake Dołgie Wielkie [116] and the Mediterranean Sea [113] compared to underlying waters, and dissolved Cu showed enrichment factors of 3 and 20 in the SSMs of Bay of Villefranche [113] and the Mediterranean Sea [117], respectively. The active interactions between organics and Cu within the SSM have been observed near the Mediterranean coast and north Norwegian fjords, and the complexing capacity of ligands with Cu in the SSM vary from 230 nM to 1790 nM in the subarctic region [118], 280 nM to 940 nM in the northwest Mediterranean [119], and 52 nM to 680 nM in the eastern Mediterranean [120].…”

Impacts of Aerosol Copper on Marine Phytoplankton: A Review

et al. 2019

View full text Add to dashboard Cite

Atmospheric deposition brings both nutrients and toxic components to the surface ocean, resulting in important impacts on phytoplankton. Field and lab studies have been done on the iron (Fe) fertilization on marine phytoplankton. However, studies on other trace metals are limited. Both bioassay experiments and field observations have suggested that aerosols with high copper (Cu) concentrations can negatively affect the primary productivity and change phytoplankton community structure. Note that with increasing human activities and global environmental changes (e.g., ocean acidification, warming, deoxygenation, etc.), the input of aerosol Cu could exceed toxicity thresholds at certain times or in some sensitive oceanic regions. Here, we provide a comprehensive review on aerosol Cu and marine phytoplankton studies by summarizing (1) physiological effects and toxicity thresholds of Cu to various phytoplankton taxa, (2) interactions between Cu and other metals and major nutrients, and (3) global distribution of surface seawater Cu and atmospheric Cu. We suggest that studies on aerosols, seawater chemistry, and phytoplankton should be integrated for understanding the impacts of aerosol Cu on marine phytoplankton, and thereafter the air–sea interaction via biogeochemical processes.

“…It is a habitat for neustonic organisms. It exhibits specific physical, chemical and biological properties (Hillbricht-Ilkowska and Kostrzewska-Szlakowska 2004;Cunliffe and Murrell 2009;Antonowicz et al 2015). The presence of the surface film and surface tension properties means that the seasurface microlayer is a unique habitat that is often referred to as the neuston (Liss and Duce 2005).…”

Analyses were conducted concerning the accumulation of four metals representing the group of macroelements, i.e. sodium, potassium, calcium and magnesium in two ponds located in the city of Słupsk. Water samples for chemical analyses were collected from the surface microlayer using a Garrett net. At the same time subsurface water samples were collected. Concentrations of metals were determined using a mass spectrometer. Generally, amounts of sodium, potassium, calcium and magnesium were similar in surface microlayer and subsurface water. Only in the case of potassium and calcium was low enrichment observed in the surface microlayer in one pond, while the greatest extent for magnesium enrichment was observed in the spring period.
