Qualitative Analysis of Plastic Debris on Beaches of Brunei Darussalam
Authors
Abstract:
Plastic debris is one of the major environmental concerns for the coastal area of Brunei Darussalam. It reduces the aesthetic appeals of the beaches in the country. The current study investigates marine debris on six different beaches of Brunei Darussalam along the South China Sea. Plastic was found the most abundant among whole debris by number (90.02%) and by weight (39.12%). It was classified by size (micro (<5 mm), meso (5-20 mm), macro (21-100), and mega (>100 mm)), colour (transparent, coloured, white and black). Fourier Transform Infrared Spectroscopy (FT-IR) was used to investigate the types of plastics and additives present in it. Statistical analysis using Minitab 17 and Kruskal-Wallis test was performed for comparison of data at different study sites. All major types of plastics were found in different forms with varying quantities from which toxic chemicals may leach out during degradation. The highest abundance by the number of plastic debris was found on Muara beach with a mean value 74.428 n/m2 ± 34.33 n/m2, while the lowest abundance was found on Lumut beach 53 n/m2 ± 20.9 n/m2. The study shows beaches used for recreational facilities are likely to have more debris as compared to other beaches.

Quantitative analysis of small-plastic debris on beaches in the Hawaiian Archipelago.
Small-plastic beach debris from nine coastal locations throughout the Hawaiian Archipelago was analyzed. At each beach, replicate 20 l samples of sediment were collected, sieved for debris between 1 and 15 mm in size, sorted by type, counted and weighed. Small-plastic debris occurred on all of the beaches, but the greatest quantity was found at three of the most remote beaches on Midway Atoll a...

INTRODUCTION Tuberculosis peritonitis (TBP) is uncommon and symptoms can be non-specific. Local data are lacking and our aim is to review our local experience with TBP. MATERIALS AND METHODS Between the period of 1996 to 2004, there were 10 [male: 6; mean age, 48 +/- 18.5 years (range, 26 to 73)] cases of histologically documented TBP. Comparisons were made with pulmonary tuberculosis (PTB) p...

One thousand consecutive Brunei Darussalam patients referred with low Hb, and/or low MCV and MCH (Hb < 12.5g/dl, MCV < 76fl, MCH < 27pg) were studied in the laboratory for underlying haemoglobinopathies. 30.0% of such patients were proved to have either beta-thalassaemia trait, beta-thalassaemia major, Hb AE, Hb EE, Hb E beta-thalassaemia or Hb H disease. In some, the haemoglobin abnormality wa...

Introduction: A pterygium is an elevated, superficial, external ocular mass that usually forms over the peri-limbal conjunctiva and extends onto the corneal surface. It is more common in the tropics secondary to higher exposure to ultraviolet light. This study compares the various techniques of pterygium surgery including bare sclera, conjunctival autograft, and conjunctival mini-graft (with or...
