Abstract

Determination of heavy metal concentrations (Cd, Cu, Pb and Zn) in  different parts (muscle, bone, scale, intestine, gills and fin) of a croacker fish (S. russelli) collected from Dumai coastal waters were carried out during May to July 2009. The concentration of each metal was determined by AtomicAbsorption Spectrophotometer Perkin Elmer 3110 in the Marine Chemistry Laboratory, Marine Science Department University of Riau Pekanbaru. The results showed that Zn was found to be the highest concentrations in most of the fish body parts analyzed followed by Pb, Cu and Cd in both samples from the western and eastern regions of Dumai coastal waters. In general, the concentrations of all metals analyzed in the present study were higher in fish collected from the eastern region of Dumai coastal waters where more anthropogenic activities such as industries and human habitations along the coastal area were found. The concentration of heavy metals observed were Cd:  0.098 – 0.103, 0.189 – 0.283, 0.099 – 0.289, 0.107 – 0.302, 0.182 – 0.377 and 0.118 – 0.397; Cu: 0.130 – 0.198, 0.189 – 0.341, 0.082 – 0.073, 0.132 – 0.285, 0.520 – 0.746 and 0.175 – 0.337; Pb:  3.979 – 4.109, 4.144 – 4.601, 0.970 – 2.527, 2.853 – 4.367, 5.053 – 7.074 and 4.637 – 6.262 and Zn:  5.713 – 5.755, 7.956 – 8.558, 4.649 – 6.232, 5.730 – 7.745, 8.988 – 11.115 and 8.777 – 10.686 µg/g for muscle, bone, scale, intestine, gills and fins respectively. Concentrations of heavy metals in each body part of the fish were as follow: fin > gills > intestine > scale > bone > muscle for Cd; gills >  bone > fin > intestine > muscle > scale for Cu; gills > Fin > bone > intestine > muscle > scale for Pb and gills > fin > bone > intestine > scale > muscle for Zn. The concentrations of heavy metals in muscle were lower than other analyszed organs in the present study and this was considered to be an advantageous from the human health points of view as because muscle constitute the greatest mass of the fish that is consumed.

Abstract

The research was conducted in April 2017. The purpose was to analyze the oil content, to determined type and abundance of diatoms, and to determine the correlation between oil content and abundance of diatoms in the waters of Tanjung Balai Karimun, Riau Islands Province. Survey method used consisted of four stations with three replications. The results, the average value of oil content ranged between 0.1820-0.5413 ppm, and the abundance of diatoms were between 54-132 ind/l. The ditoms which composed of 12 species namely Bacillaria sp., Coscinodiscus sp., Fragilaria sp., Isthemia sp., Guinardia sp., Lyngbya sp., Leptocylindrus sp., Nitzschia sp., Pleurosigma sp., Rhabdonema sp., Rhizosolenia sp., and Streptotheca sp. The correlation between oil content and the abundance of diatoms was negatively strong which meant the higher the oil content the decreased the abundance of diatoms in Tanjung Balai Karimun waters. The equation regretion was y = 135.0-149.7x, and the determination coefficients (R2) = 0.561 and the coefficient correlation (r) = 0.749.Keywords: Correlation, abundance, diatoms, oil content, Tanjung Balai Karimun.

Abstract

The research was conducted in July 2014 in Air Hitam Strait of Meranti Islands Regency of Riau Province. This research aims to analyze the concentration of nitrate and phosphate and the relationship with diatom abundance. The samples were taken from 4 stations and each station was divided into 3 sampling points. The result showed the average value of nitrate and phosphate concentration were 0.122 mg/L and 0.021 mg/L. This research identified 12 genus of diatom. The highest abundance of diatom was found in Station 3 around of the floating cage locations (162.96 Ind/L) and the lowest was at Station 4 around harbor (111.11 Ind/L). The result of the simple linear regression of nitrate and phosphate concentration showed a positive relation with diatom abundance, that means if the concentration of nitrate and phosphate are raising the diatom abundance was also increasing.Keywords: Air Hitam Strait, Nitrate, Phosphate and Diatom

Abstract

A study of the relationship between oil content and the abundance of diatoms was conducted in September 2016 in the waters of Kuala Tanjung Batubara District of North Sumatra Province. Seawater samples (for oil analysis and diatoms) were collected from 4 stations. Analysis of oil content and identification of diatom was done conducted in laboratory of Chemistry and Laboratory of Marine Biology, Faculty of Fisheries and Marine Science, University of Riau. The results show that all water quality parameters measured in this study are within the tolerance range for survival of marine organisms. The oil content ranges from 0.1560 to 0.2871 ppm and diatom abundance ranges from 55 to 134 ind / l with 10 species. Based on the results of simple linear regression test, the relationship between oil content with diatomic abundance has a very strong relationship with mathematical equations y = 236,3 - 647,8x with coefficient of determination (R2) = 0,762 and correlation coefficient r = 0,873. The value of r represents a strong relationship with a negative value meaning that with increasing oil content in the waters, the abundance of diatoms in the waters will decrease.Keywords: relationship, oil content, abundance, diatoms, Kuala Tanjung.

Abstract

The research was conducted in February-March 2015 with a goal to determine the relationship between the oil content and the abundance of diatomsin Meral Karimun waters of Riau Islands Province. The survey method was applied in four stations with three sampling strata,i.e. the surface area, the middle and near the bottom. It revealed that the oil content of water ranged from 0.1797 to 0.2063 ppm and diatom abundance were between 44 to 149 cells/l, which contain of 14 species. Apparently, the oil content of seawater was not correlated (p>0.05) with diatom abundance were the coefficient correlation of (r) = 0.318. The regression equation was y = - 468.350x + 184.297 with a coefficient of determination (R2) =0.101 and a correlation coefficient (r) = 0.318. It was suggested that increasing oil content will decrease the abundance of diatoms in the Meral Karimun waters.Key Words:Meral,abundance, diatoms, oil content

Abstract

Concentration,  distribution  and  correlation  of  seven  heavy  metals  in  seawater,  sediment  and gastropod Cerithidea  obtusa from coastal waters in the proximity of abandoned tin mining in Singkep Island has been evaluated. Samples were taken from five stations and heavy metal analysis was carried out by using AAS Perkin Elmer 3110 in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science University ofRiau. The mean concentrations  ofCd, Cu, Pb, Zn, Ni, Mn and Cr were 0.0373,  0.0776,  0.1340,  0.1692,01789,  0,1205  and  0.3232  mg/1 in  seawater;  2.0445,   11.5359,  24.6859,  23.7992,  13.2925,  13.1097  and79.0821  f.lg/g in sediment and 3.03, 69.71, 14.30, 120.73,  11.62, 56.29 and 18.75  J..lg/g in C. obtusa, respec­ tively. In general, the concentrations of metals in coastal water receiving effluents from abandoned tin mining activities in Singkep Island were higher than in coastal waters with less mining activities. Concentrations  of all those metals in seawater were positively correlated with sediment and  gastropod and its concentrations   in sediment  were  also  positively  correlated  with  those  in  gastropod.  Mean  concentration   of  all  metals  in sediment were still below the ERM values, except for Cd which was exceeded the ERL but  they were all still below the ERM  values.  Continuous  environment  monitoring  programs  should  be implemented  in Singkep Island coastal waters to evaluate possible increase of heavy metal threat as some new sand and bauxit mining activities are taking place.Key words: heavy metal, seawater, sediment, Cerithidea obtusa, mining

AbstractThis research was conducted in July 2020 in Pelintung Dumai Waters. The purpose of this study was to determine the total oil concentration in the waters of the Pelintung Industrial Area. The method used is a survey method which is conducted at 4 stations. Total oil concentration samples were analyzed by gravimetric method. Based on the results of the study, the highest oil concentration was in the Pelintung Industrial Area waters (station III), namely 0.3245 ppm and the lowest concentration was in the mangrove forest area (station IV), namely 0.0738 ppm. The results of the Anova test carried out on the total oil concentration value between research stations obtained p value (0.019) <0.05. This shows that the total oil concentration between research stations is different.Keywords: Pelintung Village, Oil
