ABSTRACTThe study of Pb, Cd, Cu, Hg, and As and Fe in Natuna coastal waters, Riau Islands was conducted in November 2012. Water and sediment samples were collected from 35 stations by purposive sampling method and those heavy metals were analysed using Atomic Absorption Spectrophotometer, flame type (FAAS). The results showed that concentrations of total Pb, Cd, Cu, Hg, and As in surface water were below instrument detection limit (2 µg/L for Pb, Cd, and Cu; 0.02 µg/L for Hg and As). Moreover, the concentration of metal Fe in surface water was 0.021-0.054 mg/L. Concentrations of Pb and Cu in sediment were 0.05-22.67 mg/kg and 3.77-11.00 mg/kg, respectively, at which the highest concentrations were found near Binjai Estuary. Those concentrations were significantly below the standard levels set by CCME (2002) and ANZECC/ARMCANZ (2000). Concentration of Fe in sediment varied from 751.13-2309.12 mg/kg and showed similar spatial distribution to Cu-in-sediment. No standard level for Fe in waters was available. Generally, it can be concluded that Natuna coastal water was still uncontaminated.  Keywords: heavy metals, iron metal, Natuna coastal waters.

The country of India is the unique where different cultural heritage as well as festivals were found. Mainly the West Bengal state is known as various religious festivals, but Durga Puja is one of the biggest and end of this festival idol are immersed in the water bodies. Sainthia town found in the district of Birbhun, West Bengal, India which is present in the south bank of the Mayurakshi river. The idol immersion mainly effect on water as well as sediment quality of this river Mayurakshi near railway bridge at Sainthia. The study will be discussed for immersion effect of this sampling station, because in this point totally Sainthia town Durga idols were immersed. The water and sediment samples were collected at 7:30 am on 9th October 2019 during pre-immersion (before immersion) and 7:30am on 10th October 2019 during the post immersion (after immersion) in this time of periods. Mainly, the Durga idols are been made up by non-biodegrable substances such as clay, plaster of paris, cloths, paper woods, thermocols, jutes and synthetic paints etc. these are mainly toxic substances. Over all the used materials in making of idol, the thermocol is nonbiodegradable while paints contained highly toxic heavy metals like Cr, Cd and Pb. In this study has been made to analysis the physicochemical parameters like temperature, pH, TS, TDS, TSS, EC and three heavy metals like Cr, Cd and Pb on the collected water and sediment samples of the Mayurakshi river on before and after idol immersion periods of near railway bridge sampling station. The analysed results by based on various physicochemical parameters showed that the after immersion in the river Mayurakshi increases concentration of heavy metals and changes other physicochemical parameters of the both water and sediment samples. Finally concluded that, these changes of different parameters are harmful for aquatic life and human beings as well as the level of water pollution highly increases in this Mayurakshi river. So, the huge religious activities mainly causes of the water pollution where huge disturbing aquatic ecosystem.

The Impact

SummaryPersian Gulf hosting ca. 48% of the world’s oil reserves; has been chronically exposed to natural oil seepage. Oil spill events have been studied over the last decade; however, the influence of chronic oil exposure on the microbial community of the Persian Gulf has remained unknown. We performed genome-resolved comparative analyses of the water and sediment’s prokaryotic community along the Gulf’s pollution continuum (Strait of Hormuz, Asalouyeh and Khark Island). The continuous exposure to trace amounts of pollution has shifted the microbial profile toward the dominance of Oceanospirillales, Flavobacteriales, Alteromonadales, and Rhodobacterales in Asalouyeh and Khark samples. Intrinsic oil-degrading microbes present in low abundances in marine habitats; experience a bloom in response to oil pollution. Comparative analysis of the Persian Gulf samples with 106 oil-polluted marine samples reveals the pollutant’s hydrocarbon content, exposure time and sediment depth as main determinants of microbial response to pollution. High aliphatic content enriches for Oceanospirillales, Alteromonadales and Pseudomonadales whereas, Alteromonadales, Cellvibrionales, Flavobacteriales and Rhodobacterales dominate polyaromatic polluted samples. In sediment samples, Deltaproteobacteria and Gammaproteobacteria had the highest abundance. In chronic exposure and oil spill events, the community composition converges towards higher dominance of oil-degrading constituents while promoting the division of labor for successful bioremediation.Originality-Significance StatementThe impact of anthropogenic oil pollution on the microbial community has been studied for oil spill events; while the influence of long-term chronic exposure to oil derivatives on The microbes has remained unknown. Persian Gulf hosts ca. 48% of the world’s oil reserves and has been chronically exposed to natural and accidental oil pollutions. Different pollutant profilesin different locations and the recurrent pollution events; make Persian Gulf an ideal model system to analyse the impact of oil hydrocarbon on the microbial community and the recovery potential of marine ecosystems after pollution. In this study we perform an extensive analysis of thhe Persian Gulf’s water and sediment samples along the water circulation and pollution continuum for the first time. Our results show that these long-standing trace exposure to oil has imposed a consistent selection pressure on the Gulf’s microbes; developing unique and distinct communities along the pollution continuum. Our extensive genome-resolved analysis of the metabolic capabilities of the reconstructed MAGs shows an intricate division of labor among different microbes for oil degradation and determine the major drivers of each degradation step. Intrinsic oil-degrading microbes (e.g., Immundisolibacter, Roseovarius and Lutimaribacter) bloom along the Persian Gulf’s pollution continuum and function as the main oil degraders. Comparative study of PG datasets with 106 oil-polluted marine samples (water and sediment) reveals similar community compositions in the Persian Gulf’s water and sediment samples to those of oil spill events and suggests hydrocarbon type and exposure time as the main determinants of the microbial response to oil pollution.

Cau River, one of the major rivers of Thai Binh River Systems, has been under pressure from discharge from the economic and social development activities of the region. Water and sediment samples will be collected along Cau River to determine the spatial variability of metal in Cau River. Sediments collected from Cau River were extracted sequentially to investigate the distribution and fractionation of metal in Cau River. Results showed that the presence of certain metals in water and sediment with the concentrations ranged in a wide variation. In water Cu (58-181 μg/L), Pb (0.6-1.85 μg/L), Zn (18.1-32.5 μg/L), Cd (0-0.02 μg/L), Ni (3.04-4.41 μg/L), Cr (2.72-5.07 μg/L); in sediment Cu (27.6-401 mg/kg), Pb (0-282 mg/kg), Zn (3.9-71.9 mg/kg), Cd (0.01-2.44 mg/kg), Ni (2.24-5.89 mg/kg), Cr (4.08-11.5 mg/kg). Sequential extraction for study the distribution of metal species in sediment showed that metal mainly concentrated immobile form of residues fraction, organic compound bound fraction and Fe-Mn oxide associated fraction. This dominant existence of metal result in the tendency of metal assimilation in sediment and low bioavailability. However, some toxic metals such as Cd, Cr found moderated soluble form must be studied more for their release to water phase and and bioaccumulation.

Human activities on environmental resources have negatively affected floras and faunas in maintaining fair balance. In this research study, selected heavy metals (Al, As, Cd, Cr, Cu, Fe, Hg, Pb, Ni, Zn) concentration in three fish species (Clarias gariepinus, Heterotis niloticus and Anguilla labiate), surface water and sediment samples in Ogbaru axis of River Niger, Anambra State, Nigeria. We evaluated the samples using atomic absorption spectrophotometer (AAS). The result of heavy metals (Cu, Fe, Zn, Ni, Pb, Cd, Al, Cd) analysis in fish samples showed that Cr was detected in Clarias garipinus and Anguilla labiate with a concentration of 0.001mg/kg in both species but was not detected in Heterotis niloticus. Hg and Al were not detected in Anguilla labiate but both metals were detected in the other fish species with a mean concentration of 0.311mg/kg and 0.019mg/kg respectively for Clarias garipinus and 0.001mg/kg and 0.005mg/kg respectively for Heterotis niloticus. In decreasing order, the heavy metal concentration in Clarias garipinus in increasing order of Cu >Fe > Ni > Hg > Pb > Zn > As > Cd > Al > Cr, while Heterotis niloticus followed the order Cu > Zn > Fe > Ni > Pb > Cd > Al > As > Hg > Cr, and  Anguilla labiate followed the pattern of Cu > Fe > Zn > Ni > Pb > Cd > Cr > As > Hg > Al. For surface water, As (0.005mg/l), Cd (0.032 mg/l), Cr (0.099 mg/l), Cu (0.186 mg/l), Fe (2.308 mg/l), Hg (1.501 mg/l) and Pb (0.724 mg/l) showed high concentration for the raining season compared to dry season, as Al (0.246 mg/l), Ni (0.773 mg/l) and Zn (2.903 mg/l) were dominant during dry season, while sediment samples of Cr (0.112 mg/kg), Cu (0.029 mg/kg), Ni (0.945 mg/kg) and Pb (0.039 mg/kg) concentration in raining season were higher than dry season and vice versa for other As, Cd, Fe, Hg, Zn. Correlation matrices showed positive value showing that heavy metals were from a similar source with migration route and vice versa for negative correlation. Health and exposure risk assessment was conducted for carcinogenic and non-carcinogenic exposure in adults and children, where the cumulative cancer risk was within USEPA regulatory standard (1.0E-6 – 1.0E-04) and cumulative hazard index were above 1 for adults (2.02) and children (4.93), implying that children are at risk of having adverse health issues compared to adults. Therefore, there is a need for regulatory advocacy and special care to mitigate anthropogenic release and safeguard the environment.
