My dearest brothers and sister, Mohd Faizal Muhammad Fairuz Nur Fadilah To my lovely friend, Noraziah Thank you for everthing....... iv ACKNOWLEDGEMENTS “In the name of Allah, the most gracious, the most compassionate” First and foremost, I would like to express my greatest gratitude towards my supervisor, Assoc. Prof. Dr. Mohd Ismid Mohd Said for his encouragement, guidance, advices and motivation. Without his continuous support and guidance in completing this report, it would not have been completed successfully. I would also like to express my deep gratitude to my co-supervisor, Dr. Shamila Azman for her valuable time, guidance, attention and her never waver support towards the completion of this report. I also would like to share my highest gratitude towards all staffs of Environmental Engineering Laboratory University Teknologi Malaysia, Mr Ramlee, Mr Azreen, Pak Usop, and Miss Shuhada for their help during the experiments. Without their assistance the report will not be completed. In the meantime, I would also like to express my appreciation to my family and friends who were being supportive all this while, thank you very much for your support and love your help will never be forgotten. For the name mentioned or not mentioned that have involve in completing my master project, Only Allah could pay your kindness. Last but not least, I hope this study will gave a beneficial for this field of study especially in conducting for the future study. v ABSTRACT Pen shell of the family pinnidae is a popular food source and had high commercial value in a number of Asia-Pacific countries. Pen shell is also one of the important fisheries resources and it can easily be established as important commercial species. Environmental studies on pen shells species was conducted at Merambong Island and Merambong Seagrass shoal off South Western Johor coast, Malaysia. A total of 39 samples of pen shells were collected from two different stations during low tides. From the samples, four species of pen shells were identified. Among the 4 species, 3 species belonged to the genus Pinna (P.bicolor, P.deltodes, and P.atropurapurea) and one species was Atrina (A.vexillum). Seawater samples were collected during low tide (0-0.2m height) at four stations which located at Merambong Island and Merambong Seagrass Shoal. Concentration of heavy metal arsenic (As), cadminium (Cd), chromium (Cr), cooper (Cu), lead (Pb), mercury (Hg), nickel (Ni), iron (Fe), manganese (Mn) and zinc (Zn) were measured in water and soft tissues of the pen shells. The highest concentrations of heavy metal in water were As, Cu, and Hg in ranged between 0.100-0.142, 0.142-0.189, and 0.028-0.046 mg/L respectively. The highest metals were As, Cr and Hg in both of P.bicolor, P.deltodes, P.atropurapurea and A.vexillum. The highest concentration of metal in water and pen shells were recorded at Merambong Island, while the lowest concentration was recorded at Merambong Seagrass Shoal. Land based activities and waste discharged from nearby areas which includes oil refineries and power station are main source of metal pollution in the area. vi ABSTRAK Pen shell merupakan sejenis makanan laut yang terkenal terutaman di negara- negara Asia. Kajian ke atas siput beliung meliputi kawasan pulau merambong dan kawasan hamparam rumput laut yang terletak di selatan barat Malaysia. Sejumlah 39 sampel pen shell dipungut dari dua station semasa air surut. Daripada sampel yang diperolehi, empat spesies dikenalpasti. Tiga spesies dikenalpasti dalam jenis Pinna (P.bicolor, P.deltodes, and P.atropurapurea) dan satu spesies jenis Atrina (A.vexillum). sampel ait laut diambil semasa air surut iaitu pada ketinggian 0m-0.2m di empat station. Kandungan logam As, Cd, Cr, Cu, Pb, Hg, Ni, Fe, Mn dan Zn dikenalpasti pada air dan tisu lembut siput beliung. Kandungan tertinggi logam berat pada air laut adalah As, Cu, dan Hg iaitu masing-masing mencatatkan bacaan dalam lingkungan 0.100-0.142mg/L, 0.142-0.189mg/L dan 0.028-0.046mg/L. Kandungan logam yang tertinggi dalam empat spesies pen shell adalah Fe, Mn dan Zn. Bagaimanapun, kandungan logam yang ditemui dalam siput beliung masih di bawah nilai yang dibenarkan oleh piawai pemakanan (FAO dan WHO). Kandungan logam pada air laut dan pen shell yang dicatatkan di pulau merambong lebih tinggi jika dibandingkan dengan kawasan hamparan rumput laut. Aktiviti pengerokan untuk tebusguna tanah, pelabuhan yang melibatkan memecat minyak, dan station bahan api dikenalpasti sebagai pegumbang pencemaran. vii TABLE OF CONTENTS CHAPTER TITLE PAGE DECLARATION ii DEDICATION iii ACKNOWLEDGEMENTS iv ABSTRACT v ABSTRAK vi TABLE OF CONTENTS vii LIST OF TABLES x LIST OF FIGURES xi LIST OF ABBREVIATIONS xiii 1 INTRODUCTION 1 1.1 Overview 1 1.2 Statement of Problem 2 1.3 Objective of Study 3 1.4 Scope of Study 3 1.5 Need of Study 4 2 LITERATURE REVIEW 5 2.1 Characteristics of Pen Shell 5 2.1.1 Diagnostic Characters 6 2.1.2 Habitat and Biology 7 viii 2.2 Source of Food 10 2.3 Distribution of Pen Shell 11 2.4 Physical Water Quality Parameter 14 2.4.1 Total Suspended Solid 14 2.4.2 Turbidity 15 2.4.3 Temperature 16 2.4.4 Salinity 17 2.5 Chemical Water Quality Parameter 18 2.5.1 Dissolved Oxygen 18 2.5.2 Biological Oxgyen Demand 19 2.5.3 Chemical Oxygen Demand 20 2.5.4 pH 21 2.5.5 Nutrients 23 2.5.5.1 Phosphorus 23 2.5.5.2 Ammoniacal Nitrogen 24 2.5.6 Metals 25 2.5.6.1 Arsenic 25 2.5.6.2 Cadmium 26 2.5.6.3 Chromium 27 2.5.6.4 Copper 28 2.5.6.5 Lead 29 2.5.6.6 Mercury 29 2.5.6.7 Nickel 31 2.5.6.8 Iron 32 2.5.6.9 Manganese 32 2.5.6.10Zinc 33 2.5.7 Oil and Grease 34 2.6 Marine Pollution 35 2.7 Impact of Heavy Metals in Marine System 35 2.8 Marine Water Quality Standard 37 2.8.1 Malaysian Interim Marine Water Quality Standard 37 2.8.2 Singapore Marine Water Quality Criteria 38 2.9 Marine Water Quality Standard 39 ix 2.9.1 Food and agriculture Organization and World Health Organization Standard 39 3 METHODOLOGY 41 3.1 Introduction 41 3.2 Study Area 41 3.3 Sampling Method 47 3.3.1 Specimen Collections and Identification 47 3.3.2 Pen Shell Sample 49 3.3.3 Water Sample 51 3.3.3.1 Grab Sample 52 3.3.3.2 Sample Preservation 52 3.3.3.3 Chemical Changes 53 3.3.3.4 Biological Changes 53 3.4 Chemical Analysis 53 3.4.1 Metal Testing 55 3.4.3.1 Spectrometer Analysis ICP-MS 57 3.4.3.2 Manual of ICP-MS 58 3.4.3.3 ICP-MS Advantages 58 3.5 Data Analysis 59 4 RESULT AND DISCUSSION 60 4.1 Distribution of Pen Shells 60 4.2 Species Identification 62 4.3 Water Quality Analysis 66 4.3.1 Ammoniacal Nitrogen 66 4.3.2 Salinity 67 4.3.3 Oil and Grease 67 4.3.4 Total Suspended Solid 68 4.4 Heavy Metal in Water 70 4.5 Heavy Metal in Pen Shells 73 x 5 CONCLUSION AND RECOMMENDATION 77 5.1 Conclusion 77 5.2 Recommendation 78 REFERENCES 79 1 LIST OF TABLES TABLE NO.
