“…Metal plating, battery cells, dyes and pigments, chemical fertilizers, gasoline additives are the main Lead pollution sources in an aquatic ecosystem [8], [9]. In the present study mean concentration of lead values varies between 1.55 mg/L to 9.43 mg/L were shown in Table 6.…”

Abstract:The current study was carried out for examining the heavy metal pollution profile of seven urban ponds in Chavara industrial area, south west coast of India. The study was conducted seasonally for a period of one year from January 2014 to December 2014. Results obtained from AAS analysis showed that toxic heavy metals such as copper (Cu), Manganese(Mn), zinc(Zn), Iron(Fe), lead(Pb), Cadmium(Cd), Nickel(Ni), Cobalt (Co), and Chromium(Cr) in the water samples were found to be higher than drinking water standards prescribed by WHO, BIS and FAO. This study is an attempt to compare the hydrological assessment of heavy metals in water of different ponds due to pollution from near industry-KMML, situates in Chavara, Kollam, India.

“…Lowest mean value for manganese was reported in station two (3.12 mg/L). Mean value of manganese ranged from 1.52 mg/L to 9.15 mg/L in S7 were shown in [8], [9]. In mammals, manganese exposure on embryonic stage leads to foetal-toxicity and decreased postnatal growth [7], [10].…”

“…Although Cr had the highest concentration among the heavy metals detected, its bioavailability in plants (71.5 ppm) was lower than that available to manganese (192.3 ppm). This high level of metals in sediment demands that immediate action to be initiated to implement necessary environmental mitigation measures for the lake (Jumbe and Nandini, 2009).…”

Pollution is the introduction of contaminants, which cause adverse change, into the natural environment and mainly from external inputs like sewage, waste from industries, oil spills and agricultural use of pesticides. Anthropogenic activity-reflected in the use of toxic metals and organic pollutants-has increased levels of soil contamination and damage to aquatic systems. Ecosystems maintain water quality and withstand pressure from pollution better if they are naturally equipped with biodiversity. Algae regularly develop in fresh water and seawater and some species grow in high-salt environments. Algae quickly reponds to changes in their environment as a consequence of changes in water chemistry, affecting their diversity, community composition and abundance. Recently, algae have been used in bioremediation and to cleanup wastewater due to their high efficiency in absorbing both organic and inorganic pollutants, incuding dissolved nutrients, heavy metals, pesticides, toxic compounds and even radiactive materials. Almost all freshwater ecosystems depend on phytoplankton because they are producers and participate in the aquatic food chain; they are also useful for water quality assessment. The present work is an effort to determine the range of variation among different groups of algae. Our results showed that four species dominated the microbial community in eutrophic waters, namely Euglena (Euglenophyta), Nitzschia (Bacillariophyta), Oscillatoria and Phormidium (Cyanophyta).

“…The contamination of sediment with heavy metals, may lead to serious environmental problem. Heavy metals are widespread pollutants of great environmental concern as they are nondegradable, toxic and persistent with serious ecological ramifications on aquatic ecology (Jumbe and Nandini, 2009). Partition of the total metal concentrations into non-residual and residual fractions or phases is used in sedimentary geochemistry to provide information regarding the binding sites of metals as well as their source and pathways by which they have been transported to the aquatic environment.…”

ABSTRACThe Present study with the determination of concentrations of non-residual heavy metals (Iron, Manganese, Lead, Cadmium, Chromium, Copper, Nickel and Zinc) in Lake Nasser bed sediments as compared with total heavy metals contents in order to identify their environmental risk in Lake water. The analysis involves testing of sediments collected from eight sampling sites along riverine and transtion zones of Lake Nasser. Organic matter content for each of the sediment samples was also reported to study the effect of its content on the accumulation of metals in bed sediments. It was found that, the non-residual heavy metal levels (mg kg -1 ) in bed sediments were 0.11±0. 20.4, 19.9, 25.2, 38.6, 57.6, 49.3, 41.1 and 45.8% from the total content of these metals respectively. Fe-Mn oxides and organic matter seem to be the main carrier phases for the non-residual fraction of these metals. The order of non-residual metal concentrations in sediment samples was found to be Fe>Mn>Zn, Ni>Cu>Cr>Pb>Cd. In the present study, sediment quality assessment was done by calculating sediment pollution index and metal pollution index. The results of the assessment showed that, stream sediments from Lake Nasser are categorized into SPI0 natural sediments in all sites, except one site at km 403 which show SPI1 low polluted sediment. Metal pollution index highlights concentration differences between sites. Moreover, by comparing the results with sediment quality guidelines, it can be found that the Cd, Cu, Zn, Pb and Cr levels belong to the concentration below The Effect Range Low (ERL) and the toxicity to the biota in Lake Nasser was rarely occurred. It was also observed that, non-residual heavy metals were found very low compared with the agricultural land use target. This indicates that, Lake Nasser sediment can be used in amendment of agricultural land. The results of this study recommended the use of a pilot project to evaluate the characteristics of sediment for its potential use in agricultural land and to identify how sediments affect the crop yields. Some statistical applications were applied to study the behavior of the metal contents and their correlations in bed sediments.
