Opis:
The purpose of the study undertaken between May 2018 and April 2019 is to determine the effect of rain water intensity on the value of macrozoobenthos structures in Ciletuh Bay. The data used in this research and directly taken from the research site are seawater quality parameters, analysis of sample granulometry and identification of the sample macrzoobenthos, while all data processing was conducted in the laboratory. The method used in this study was purposive sampling. The result of this research in sand type sediment texture brought a count of 96 macrozoobenthos individuals. In contrast, the count was only 7 in silt type sediments. The study concluded that the effect of varied rainfall intensity impacts the water quality parameters that caused the difference types of sediment in Ciletuh Bay.

Opis:
This study aims to prove the type and abundance of macrozoobenthos are affected by the physico-chemical condition of the habitat so that it can be used as a bioindicator in assessing river water quality with a case study in the Upstream of Citarum River. The method used in this study consists of two stages, namely determining the status of river quality with pollution index and determining the components to see the relationship of the water quality parameters to the abundance of macrozoobenthos with principal component analysis. On the basis of these studies, the results were that at the location of the study status of the river quality is slightly polluted and mildly polluted. For the slightly polluted status Corbicula sp. was used as the dominant macrozoobenthos parameter with the parameters of dissolved oxygen, organic carbon and N-O in the clay-dominated sediments. In turn, for the river areas with mild pollution, Enallagma sp., Tubifex sp., and Chironomous sp. were used as bioindicators and they have a relationship with the parameters of nitrate, TSS, and P-total.

Opis:
Tunda Island has underwater beauty that has the potential to be developed into a marine tourism object. One important part of this is the fringing reef around the island. Unfortunately, this has been severely degraded. This study aims to determine if reef rubble and split rock artificial reefs have the ability to be a living space for macrozoobenthos and to measure the potential community structure. The research was conducted in August 2018 - November 2018 in the eastern part of Tunda Island, and included monitoring the initial conditions, artificial reef creating and positioning, gathering and analyzing macrozoobenthos data. The macrozoobenthos data collection was carried out from September to November 2018 as 4 observations, and was obtained using the Belt Transect method. In the analysis, the community structure data retrieved was divided into 3 categories: diversity, abundance and dominance. The diversity index obtained ranged from 0.43 – 7.65, meaning that it is of low to moderate diversity. The abundance of macrozoobenthos ranged from 1 - 18 individuals /m2 on the rubble type artificial reef and 2.13 – 4.26 individuals /m2 on the split type artificial reefs, with the most common class being gastropods. On rubble type artificial reefs, 14 macrozoobenthos genera were found to be common, while 13 genera were observed in the split type. The genus found was Culcita sp., Chicoreus sp., Diadema sp., Chelidonura sp., Thrombus sp., Chromodoris sp., Cymatium sp., Trochus sp., Terebra sp., Dardanus sp., Malea sp., Oliva sp., Opheodosoma sp., Actinopyga sp., Conus sp., Enoplometopus sp., Cypracea sp., Lambis sp., and Phylidia sp. The dominance index value was in the range of 0.18-1.00 or low to high on both rubble and split types.

Opis:
Cijulang River, Pangandaran is a river that is used for agriculture, fisheries, industry, household activities and even as a tourist attraction. Macrozoobenthos is a bioindicator that can show changes in the quality of river waters due to these activities. The purpose of this study was to determine the macrozoobenthos community structure found on the Cijulang River, Pangandaran. The research method used is Purposive Sampling. The study was conducted at 4 stations along the Cijulang River from upstream to downstream in September - November 2018. The results of the research on the Cijulang River found 27 species of 5 classes included in 3 fillum namely Mollusca (23 species), Arthropoda (3 species) and Annelida (1 species). The value of macrozoobenthos density in the Cijulang River ranges from 29.7 - 416.3 ind/m2. Diversity index ranges from 1.48 - 2.24. The uniformity index ranges from 0.49 - 0.80. The range of water quality and substrate showed variations and dynamics that were still within the tolerance limits of macrozoobenthos life and water salinity is the main causes of variations in the macrozoobenthos community structure on the Cijulang River.

The study was conducted in July - August 2018 with the aim of analyzing the concentration of lead heavy metals (Pb) in water, sediment and macrozoobenthos in the Karangsong waters area, Indramayu Regency. The research method used is a survey method with purposive sampling technique that is the determination of location based on the existence of certain objectives and in accordance with various considerations, then observed the content of lead metal (Pb) in the Central Laboratory of Padjadjaran University. The research was conducted in situ and exsitu. Parameters of insitu research include temperature, pH and DO carried out in Karangsong waters, Indramayu Regency. Exsitu research parameters include testing of lead metal (Pb) on water, sediment and macrozoobenthos conducted at the Central Laboratory of Padjadjaran University. The results showed that the Pb concentration in the Karangsong waters had exceeded the threshold, which ranged between 1,05 – 1,33 mg/l, while the Pb concentration in sediment was higher than the Pb concentration in water. Lead metal in sediment has not exceeded the threshold. The ability of macrozoobenthos to accumulate lead metal in water and sediment (Bioconcentration Factor / BCF) is included in the low accumulative category because BCF is less than 100.

Opis:
W październiku 2017 roku pobrano próby makrozoobentosu na sześciu stanowiskach w górnych partiach rzeki Wisłoki. Na ich podstawie dokonano oceny jakości wody i przypisano im klasy posługując się metodą BMWP-PL oraz indeksem Margalef’a. Jakość wód Wisłoki jest niezadowalająca – najczęstszym wynikiem oszacowania jakości jest III i IV klasa. Wynik ten jest znacznie gorszy niż oszacowanie tą samą metodą jakości wody górnych partii rzeki Jasiołki i rzeki Ropy. Rzeki te są podobne fizjograficznie i usytuowane w pobliżu Wisłoki.
In October 2017, macrozoobenthos samples were collected on six positions in the upper parts of the Wisłoka River. Based on them, the quality of water purity was assessed and the purity classes were assigned to them using the BMWP-PL method and the Margalef index. The quality of waters in Wisłoka is unsatisfactory - the most common result of the quality assessment is the 3rd and 4th water purity class. This result is much worse than the assessment of the water quality of the upper parts of the Jasiołka River and the Ropa River using the same water quality method. These rivers are similar physiographically and situated near Wisłoka.

Na tej podstawie określono strukturę taksonomiczną fauny makrobentosowej. Badaną rzekę charakteryzowała zróżnicowana struktura jakościowa i ilościowa poszczególnych taksonów, a bioróżnorodność była niska. Różnica w ilości osobników tworzących zespół bentosu w analizowanych okresach była duża, jednak pod względem jakościowym grupa ta obejmowała prawie takie same pod względem taksonomicznym organizmy.
The study results presented include an analysis of the biological material collected in May 2007 and 2012 from the Mała Ina river located in the Ina River basin. These served as the basis for determining the taxonomic structure of macrobenthos. The river studied varied with regard to the qualitative and quantitative structures of individual taxa, and the biodiversity in the streams was very low. Despite a significant difference in the number of individuals making up the benthos in the analyzed periods, in terms of quality, this group consisted of almost the same in terms of taxonomic organisms.

Opis:
The aim of this study was to develop methodological assumptions of the biotic typology and, based on these assumptions, determine the biotic types in the Polish Marine Areas. The biotic typology proposed in this paper is based on the analysis of the structure and the classification of macrozoobenthos. This group of organisms can be regarded as the main component structuring the biotic types due to their sedentary way of life and less susceptibility to spatial and seasonal changes compared with pelagic biota. Soft and hard bottom sediments occurring in the Polish Marine Areas were taken into consideration. The basic criterion of the biotic typology was to identify the predominant components of the seabed zoocoenoses – animal species and communities, from which the biotic type takes its name. As a result of the classification process the Polish Marine Areas were divided into six sub-areas of different environmental characteristics (a type of sediment, salinity and water dynamics); each of them inhabited by different macrozoobenthos communities. Consequently, the following biotic types were determined: I) Chironomidae-Oligochaeta, II) Macoma balthica-Marenzelleria sp., III) Bylgides sarsi-Macoma balthica, IV) Hydrobiidae-Cerastoderma glaucum, V) Pygospio elegans-Hydrobiidae, VI) Mytilus trossulus-Gammaridae. The proposed typology is the first comprehensive attempt at classification of the Polish Marine Areas taking into account both biotic and abiotic elements of the marine environment.
Celem pracy było przygotowanie założeń metodycznych typologii biotycznej oraz, na podstawie tych założeń, wyznaczenie typów biotycznych w polskich obszarach morskich. Proponowaną w niniejszej pracy typologię biotyczną oparto na wynikach analizy struktury i klasyfikacji zbiorowisk makrozoobentosu będących głównym składnikiem nadającym charakter typom biotycznym ze względu na trwałe związanie z miejscem występowania i nie podleganie zmianom przestrzennym i sezonowym w takim stopniu, jak biocenozy toni wodnej (pelagialu). Analizą objęto dno miękkie (piaszczyste i muliste) oraz twarde (kamieniste) polskich obszarów morskich. Podstawowym kryterium zaproponowanej typologii biotycznej było określenie dominujących składników zoocenoz dna morskiego – gatunków i zbiorowisk, od których dany typ biotyczny bierze swą nazwę. W wyniku przeprowadzonej klasyfikacji dokonano podziału polskich obszarów morskich w oparciu o te składniki środowiska, które w głównym stopniu kształtują biotop (siedlisko) i wpływają istotnie na strukturę gatunkową zamieszkujących go zbiorowisk makrozoobentosu (tj. rodzaj osadu, zasolenie i dynamika wód). W rezultacie wyróżniono następujące typy biotyczne: I) Chironomidae-Oligochaeta, II) Macoma balthica-Marenzelleria sp., III) Bylgides sarsi-Macoma balthica, IV) Hydrobiidae- -Cerastoderma glaucum, V) Pygospio elegans-Hydrobiidae, VI) Mytilus trossulus-Gammaridae. Zaproponowana w niniejszej pracy typologia jest pierwszą kompleksową próbą klasyfikacji polskich obszarów morskich uwzględniającą zarówno elementy ożywione, jak i nieożywione środowiska morskiego.

We carried out a detailed study of the kinetics of oxidation of N'-ferrocenylmethyl-N'-phenylbenzohydrazide (FcX) to ferrocenium ion (FcX+) in aqueous and organic mediums. This study using cyclic (CV) and rotating disk electrode (RDE) voltammetry showed that the FcX/FcX+ redox couple is reversible. The N'-ferrocenylmethyl-N'-phenylbenzohydrazide and ferrocenium ion diffusion coefficients (D) were calculated from these results. In addition, the electron transfer rate constant and the exchange current density for the oxidation of ferrocene were determined. A comparison of the kinetic data obtained from the two electrochemical techniques appears to show that the data from the RDE experiments are more reliable because they are collected under strict mass transport control. Have studied lake close to neutral pH - 7.67 to 7.73. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. The concentration in the surface layer of Ptot. Lake is little differentiated, is at level II quality class according to the classification of the European Union Water Framework Directive. Tested water lakes were changing the concentration of the PO43-diss - these concentrations correspond to water quality from III. The increase of the concentrations of phosphorus in the Lake may indicate a decrease in the amount of oxygen in the waters of the shallow and changes their status to release phosphorus compounds accumulated redox in sediment bottom. In the case of nitrogen-compounds nitrates and nitrites values for these indicators were at level I and II class in all the surveyed lakes in accordance with the classification of the European Union Water Framework Directive. Indicator, which indicates the high productivity of Lake is the biochemical oxygen demand (BOD5). The level of this indicator values on the studied Lake was on level III class. In the remaining Lake oxygen concentration was similar (continued in I class). Fauna of the Resko Lake bottom during summer stagnation was poor in terms of quality, which proves its considerable biological degradation. In terms of the concentration in the test macrozoobenthos Lake dominated, and Oligochaeta, Diptera larvae.

Opis:
In the summer of 2008–2009 species composition and quantity of macrozoobenthos in deposits samples collected with Ekman gripping device at 4 points of Starzyc Lake was studied. Lake Starzyc also called Chociwel is located in West Pomeranian Voivodeship and is adjacent to the town of Chociwel from South and South East of the city. In the collected material of the analysed lake macrozoobenthos organisms from the following classes were found: Oligochaeta, Hirudinea, Crustacea, Insecta and Bivalvia. The Insecta class was the most numerous one in respect of species found, including larvae of the following orders: Ephemeroptera (Leptophlebia sp., Ephemera sp., Caenis macrura (Stephens)), Trichoptera (Limnephilidae, Leptoceridae, Cyrnus sp.) Diptera and Megaloptera (Sialis lutaria L.). The density and biomass distribution in the analysed Starzyc Lake demonstrates the occurrence of unfavourable changes which may lead to eutrophication in the shallowest layers of the body reservoir and in the zone at the depth of 4.9 m. The littoral zone of the studied lake features high density and significant benthic fauna biomass with low values of PIE biodiversity index.
