Microplastic pollution in Surabaya River Water and Aquatic Biota, Indonesia

Meia Ponte River supplies water for two million people in Goiás State, Brazil. Despite its importance, the Meia Ponte River faces serious environmental problems such as the disposal of domestic and industrial effluents, what could impact the aquatic biota and the health of people who consumes its water. In this sense, here we aimed to evaluate the environmental quality and toxicity of surface water along the course of this river. Physicochemical analyses of water at Goiânia urban perimeter were higher than the limits of Brazil environmental regulations for fresh water. In relation to the diversity of species, phytoplankton classes associated to polluted environments were detected closer to urban perimeter. Allium cepa bioassay suggested that this river may contain substances with mitogenic activity. This result is in accordance with genotoxic analysis, because it was observed a significant increase in chromosomal aberrations. This data reveal the genotoxic potential of Meia Ponte River water. This genotoxicity represents a risk for aquatic biota and humans, once the genotoxic agents in water samples might cause the loss of DNA integrity, inducing damages and DNA breaks. In this context, the water utilization from Meia Ponte River without any treatment should be avoided and public policies need to be formulated and implemented to depollute this important river for Goiás State.

Abstract Lead (Pb) has been recognized as hazardous metal because it is commonly found as contaminant, interfere the survival of aquatic organisms, and cause bioaccumulation process in aquatic biota at the waters. Bioaccumulation refers to the accumulation of substances in organism that can trough the food chain reaction of aquatic tissue. Bioaccumulation may occur in milkfish cultivated in fishponds around the Buntung river, Sidoarjo, because there are a lot of factories or industrial activities operating and disposing the waste along the river. The purposes of this study are to measure the lead (Pb) content in milkfish at pond around Buntung river, Sidoarjo, and to determine concentration of water and sediment river, water and sediment of fishponds, klekap, and milkfish meat from fishponds, and also to has exceeded specified maximum limit. Design of this study is descriptive study. The samples were collected from 4 stations that located in Buntung river, Sidoarjo, include water and sediment of river, water and sediment of fishponds, klekap, meats and gills from milkfish. Analyze the lead (Pb) content of water, sediment, and biota used Atomic Absorption Spectrophotometry (AAS). The histopathology slide was made by Haematoxylin-Eosin coloration. Cells of controls are the gill filaments at magnification up to 1000 times. The results showed concentration of lead (Pb) in the river water was about 0,018–0,028 ppm, the sediment of river (2,664–3,072 ppm), the water of fishponds (0,000-0,011 ppm), the sediment of fishponds (2,974-3,220 ppm), klekap (0,176-0,192 ppm), and milkfish meat (0,175-0,190 ppm). The lead concentration of each objects have lower than standardization of quality. The injuries found on the gill filaments of milkfish sample histopathologicaly are cell necrosis, rupture of secondary lamella, and congestion.

Lake Aur has many aquatic biota as well as become one of the mainstay attractions in Musi Rawas Regency. Community activities and lack of awareness of tourists on the cleanliness and importance of maintaining the lake environment have an impact on water pollution. One of the organisms that can be used as an indicator of river water quality is microalgae. The purpose of this study is to determine the types of microalgae Bacillariophyta divisions that exist in the lake Aur, Musi Rawas.The type of research used is survey research. Bacillariophyta Division consists of two classes, 6 orders, 7 families, 8 genera and 11 species. Observed environmental factors: temperature: 290C, pH: 6.7, Brightness: 115 cm and dissolved oxygen amount of: 38 mg / L. Based on the results of research and discussion, we can conclude that: the type of microalgae division bacillariophyta were found in Lake Aur namely: Cylotella sp, Eunotia sp, Eunotia pectinalis, Fragilaria croronensis, Synedra acus, Nitzschia sp, Nitzschia acicularis, Surirella sp, Surirella elegans, Pinnularia sp and Stauroneis sp.

High Nutrient

Laundry wastewater is dangerous if it is immediately disposed into a river without treating it first. One of the chemicals contained in laundry wastewater is a phosphate compound. If laundry wastewater is discharged directly into the river it will increase the phosphate content as a nutrient in river water which can be dangerous for living creatures. The high nutrient in the river will cause eutrophication in the river which will adversely affect aquatic biota. One treatment that can be done is the process of adsorption with activated carbon made from bintaro fruit shells.

Jet fuels such as JP-4 can be introduced into the environment and come in contact with aquatic biota in several ways. Studies in this laboratory have demonstrated JP-4 toxicity to fish. Benzene is the major constituent of the water soluble fraction of JP-4. The normal surface morphology of bluegill olfactory lamellae was examined in conjunction with electrophysiology experiments. There was no information regarding the ultrastructural and physiological responses of the olfactory epithelium of bluegills to acute benzene exposure.The purpose of this investigation was to determine the effects of benzene on the surface morphology of the nasal rosettes of the bluegill sunfish (Lepomis macrochirus). Bluegills were exposed to a sublethal concentration of 7.7±0.2ppm (+S.E.M.) benzene for five, ten or fourteen days. Nasal rosettes were fixed in 2.5% glutaraldehyde and 2.0% paraformaldehyde in 0.1M cacodylate buffer (pH 7.4) containing 1.25mM calcium chloride. Specimens were processed for scanning electron microscopy.

Fingernail Clams

Fingernail clams (Muscu1ium transversum) are dominant bottom-dwelling animals in some waters of the midwest U.S. These organisms are key links in food chains leading from nutrients in water and mud to fish and ducks which are utilized by man. In the mid-1950’s, fingernail clams disappeared from a 100-mile section of the Illinois R., a tributary of the Mississippi R. Some factor(s) in the river and/or sediment currently prevent clams from recolonizing areas where they were formerly abundant. Recently, clams developed shell deformities and died without reproducing. The greatest mortality and highest incidence of shell deformities appeared in test chambers containing the highest proportion of river water to well water. The molluscan shell consists of CaCO3, and the tissue concerned in its secretion is the mantle. The source of the carbonate is probably from metabolic CO2 and the maintenance of ionized Ca concentration in the mantle is controlled by carbonic anhydrase. The Ca is stored in extracellular concentric spherical granules(0.6-5.5μm) which represent a large amount of inertCa in the mantle. The purpose of this investigation was to examine the role of raw river water and well water on shell formation in the fingernail clam.
