Impact of heavy metals on the food web in the Mediterranean lagoon, Lake Burullus, Egypt
Research on the impact of heavy metals and their accumulation in ecosystem elements of Lake Burullus is still scarce. Therefore, this study focuses on the relationship between the levels of heavy metals in the lake
Distribution of cyclopoid copepods in different subterranean habitats (southern Poland)
The majority of Polish studies on freshwater cyclopoids focused on surface water fauna. There are relatively few data on copepods of subterranean waters. Thus, in our research, copepods were collected from 37 different, mostly groundwater-dependent
Development of an extraction procedure and analysis of electrostatically stabilized silanates from aqueous solutions
The analyzed organosilicon derivatives of electrostatically stabilized silanates belong to a group of pentacoordinated compounds. These derivatives are:1-(N-morpholiniomethyl)spirobi(1-sila-2,5-dioxacyclopentan-3-on)at,1-(N-morpholiniomethyl)spirobi(1-sila-2,5-dioxa-4-methylcyclopentan-3-on)at,1-(N-morpholiniomethyl)spirobi(1-sila-2,5-dioxa-4-(i-propyl)cyclopentan-3-on)at. In the course of the work, the extraction process and optimization of conditions for separation and determination
Biodiversity of benthic diatom flora in the coastal zone of Puck Bay (southern Baltic Sea): a case study of the Hel Peninsula
The paper presents the results of the analysis of diatoms from surface sediments (stones, sands) and macroflora (seagrass, macroalgae) collected at 16 sampling sites located along the inner coastal zone of Puck Bay (southern Baltic
