| Abstract | NOTE 520 Current study was focused on coastal pollution quantification linked with its effects as initiation step for effective coastal pollution management program in eastern coast, Thailand , since inadequate reliable , scientific pollution information is avai lab le regarding those regional coasts . Field s ampling and analysis was carried out in 3 selected beaches (AngSila, Bangsaen, Samaesarn) from February – October 2015 as covering dry and monsoon period. Relatively higher coastal debris pollution rate was obser ved at mean density of 9.72 counts /m 2 , 99.91g /m 2 of weight and 936.90 cm 3 /m 2 of volume . Plastic was the dominant occupied debris category in composition, emphasizing urgent requiremen t on plastic pollution control for all si tes. Fishing gear parts, vesse l items, f ood and beverage particles were highly accumulated litter items , indicating marine fishery sector , shell - fish culture and beach - goers as main sources along these coastlines with spatial and temporal variability . Debris quantitative results have i mplied relatively increasing trend of deposition in monsoon , depended on characteristics of beach location linked with degree of anthropogenic activities and climatic factors related seasonal variation. Beach pollution has recorded significant impact on in vertebrate inter - tidal communities, reflecting micro - plastic ( 0.2 - 0.6 counts/g) and petroleum hydrocarbon ( 0.039 – 0.119 μg/g) accumulation in biotic samples. Toxic pollutants p revalence in biotic communities is associated with characteristics of contamina ted beach habitats, where they survive . Contamination of Bivalve sources reveals possible health risk in consumption of seafood sources in these regional coasts. This study recommends site specific pollution control mechanism under awareness, exclusion, re cycling, reuse and reduction. Fishery and shell - fish culture practices need to be main focus of management actions in AngSila, while tourism based recreational actions need to be prioritizing issues in pollution control program in Bangsaen and Samaesarn. R esults of this study are also useful as reference data to evaluate the success of applied activities. |
