Abstract Large branchiopod crustaceans are among the most threatened freshwater invertebrates of the world. They are regarded as a flagship group in the conservation of temporary waters, and knowledge of their ecology and conservation has developed rapidly in recent years, especially in the Mediterranean region. Little is known, however, about population functioning in species associated with vernal pools in cooler temperate areas, despite recent data showing a significant decline in their localities. The present study was conducted in western Poland, on a cluster of vernal pools known to host a Central European diversity hotspot of large branchiopods. We collected data on water and sediment quality, as well as hydroperiod length, to determine their effect on the occurrence of four large branchiopod species present in the ponds during our samplings: Eubranchipus grubii (Anostraca), Lynceus brachyurus (Laevicaudata), Cyzicus tetracerus (Spinicaudata) and Lepidurus apus (Notostraca). According to the statistical analyses, the presence or absence of particular species was affected by hydroperiod length, heavy metal content in the sediments of the marginal zone of the pond, total water phosphorus content, and pH value. Since previous studies show that deep and relatively small kettle-hole ponds seem to be the most vulnerable to human-induced changes in water nutrient contents and acidification, large branchiopod populations of this type of pools should be the first target for monitoring and active forms of protection, with the aim of maintaining the good water quality. Shallow shore-bursting type ponds are subject to increased heavy metal contamination and require activities reducing the influx of these elements from their agricultural catchment. Possible forms of protection are suggested, and the use of large branchiopods as an umbrella group in temporary waters of temperate climate is also discussed.

The present study was conducted to figure out the heavy metals (Cd, Co, Cu, Fe, Hg, Mn, Mo, Ni, Pb and Zn) concentrations in water, sediments and fish species from the Rupsha River, Khulna, Bangladesh to spot the heavy metal contamination level. Heavy metals are dangerous because they're non-biodegradable and having an extended half-life period. The heavy metal contamination could also be an excellent concern, especially for aquatic life. The metal concentration within the water sample from the Rupsha River was significantly above the rule values of WHO and USEPA respectively. Moreover, the concentration of metal within the sediments was also greater than the respective probable effect concentrations of the sediment quality guidelines. Furthermore, consistent with the fish standards, these studied fish species weren't found to be contaminated by heavy metals. It’s concluded that each of the heavy metals from the whole sample didn't exceed the standard maximum level. This study demonstrated that water of Rupsha River isn't safe for aquatic organisms also like humans in terms of Pb, Cd and Cr contents as accumulated through consumption.

The Impact

AbstractThe impact of anthropogenic activities such as mining, agriculture and urbanization is causing heavy metal contamination in many freshwater ecosystems. The concentrations of eight elements (As, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the Spekboom River, South Africa, were studied using enrichment factor (EF) and geo-accumulation index (Igeo) to assess the extent of pollution in the river. Sediment samples were collected and analyzed using sequential inductively coupled plasma—optical emission spectrometry. The results showed deterioration of the sediment quality with high concentration of Cr and Ni at all the sites, this is a reflection of contamination from the various anthropogenic activities in the area. The current levels of Cr and Ni could be detrimental to the river and may pose a serious threat to the aquatic organisms and humans, as the sediment could act as a secondary source of metal pollution in the water. It is therefore recommended that urgent action should be taken to control effluents from anthropogenic activities to the river in order to prevent further pollution.

This study concerns the distribution and potential sources of elevated heavy metal concentrations (Cu, Zn, Pb, Cd, As) in surface sediments of the Dongzhai Harbor, Hainan Island,a national important mangrove ecosystem protection area.It was found that the pollution of As may occur occasional biological effect by numerical Sediment Quality Guidelines. Further, Geoaccumulation indices (Igeo) suggest there are serious pollution levels of As at all five stations. Spatial distribution of ecotoxicological index and pollution load index suggested that most of the surface sediments have a 9% probability of being toxic and the potential ecological risk zone appear in northern and southern of Dongzhai Harbor. Correlation analysis, principal component analysis, and cluster analysis showed that these metals primarily originate from natural sources. As and Pb resulted primarily from aquaculture, and combustion of gasoline and diesel fuel by ships. The present study provides a baseline record of heavy metals in mangrove surface sediments on the Dongzhai Harbor, and provide a useful aid for sustainable marine management in this region.

By the river, mercury waste from the processing of trommel is transported through estuary which will ultimately pollute the waters of the Kayeli Bay. Polymesoda erosa shells are one type of shellfish that is often used in monitoring heavy metals of mercury, especially in the estuary region. This study aims to analyze the concentration of heavy metal mercury (Hg) in water, sediments and Polymesoda erosa shells in the Waelata River and Anahoni River in Buru Regency. The results showed that the concentration of mercury heavy metals in water in the Waelata River and Anahoni River were not detected at all research stations and were below sea water quality standard for marine biota based on Minister of Environment Decree No. 51 of 2004 which is 0.001 ppm. The concentration of mercury heavy metals in sediments has an average range of 0.1340.887 ppm and is below the sediment quality standard based on ANZECC/AMRCANZ (2000) of 1.0 ppm. The concentration of mercury heavy metals in Polymesoda erosa shells has an average range of 0.1230.206 mg/kg and under the Maximum Limit of Heavy Metal Contamination in Food refers to the Indonesian National Standard (SNI) No. 7387 of 2009 which is 1.0 ppm.

Nowadays, contamination monitoring in Indonesia still focused on traditional method like only depend on measurement of chemical and physical parameter.  In addition, the use of organism, known as bioindicator brings some advantages such as knowing about habitat alteration and relationship between organism and environment. Fish from genus Oryzias had been known in Malaysia and Japan as a sensitive bioindicator. One of species, O. javanicus, was found in Kramat Kebo estuary, West Java, Indonesia. This preliminary study aims to determine metal distribution in water and sediment in Kramat kebo estuary, as a habitat of O. javanicus. It is also a preliminary study to assess possibility of O. javanicus as a bioindicator of heavy metal contamination in coastal area.  Sampling was conducted on March and September, 2014 and analysis of total metal was done by Atomic Absorbance Spectrophotometry. Result showed that metal in water still below the threshold value by Ministry of Environment. Metal in sediment analyzed by Sediment Quality Guidelines Quetiont (SQG-Q) index, showed that all stations has SQG-Q value < 0.1, which is means that Kramat Kebo estuary is unimpacted area. We conclude for this preliminary study that existence of O. javanicus were related to less polluted of heavy metal in estuary and it suitable for bioindicator of uncontaminated heavy metal area.

The water column and the sediment in the S. Domingos Mine area and the associated drainage stream are heavily contaminated by heavy metals. The Chanca Reservoir, into which this stream flows, shows a localized area where the sediment is contaminated by heavy metals, but in general the water column does not show any contamination. Both water column and sediment quality were analysed, including determination of total heavy metal concentration as well as acid volatile sulfide (AVS) and simultaneously extracted metal (SEM). The ratio between SEM and AVS is less then 1 for almost all sampling sites, showing that the Chanca Reservoir appears to be protected in most areas with respect to both sediment and water column toxity.

This area, which is located near the Banten Bay, is quite active with anthropogenic activities such as industry, fisheries, settlements, and shipyards that have the potential to pollute the environment with heavy metals. This study aims to determine the chemical environmental conditions of the waters and the concentration of heavy metals in the sediments of Banten Bay. Sediment samples were taken at five stations consisting of river and bay sections in April, May, July, August, and September 2019. Heavy metal content in sediments was analyzed according to APHA 2012 using hydrochloric acid and nitric acid destruction methods. The results of heavy metal concentrations in sediments were compared with ANZECC 2000 regulations and sediment quality was determined using the Geo-accumulation Index. The sediment at the observation site is dominated by the silt fraction. The concentration of heavy metals in this study was obtained in the form of lead (Pb) ranging from <0.05 to 6.408 mg / Kg, copper (Cu) ranging from 0.059 to 8.791 mg / Kg, and cadmium (Cd) ranging from 0.042 to 0.605 mg / K. While based on The level of heavy metal contamination in sediments using the Geo-accumulation index (I Geo), the value of all metal types in each month has a value <0.000 at all observation stations. Thus it is concluded that the concentration of heavy metals in the sediment is lower than the threshold determined during the observation. So that the metal concentration weight in the sediment has no significant effect on the environment.
