内容記述タイプ Abstract
内容記述 Toxic effects of triphenyltin (TPT) on the marine alga Eucheuma denticulatum obtained from Nain Island, North Sulawesi, Indonesia have been examined in laboratory condition. The algal samples were first acclimated in laboratory prepared seawater for three days. The algae were then divided into 12 culture chambers for treatments with different concentrations of TPT between 5-30 μgl^<-1> with 5μgl^<-1> interval, and in another container for control. After two-week experimentation, some samples of algae were obtained from each chamber for histopathological examination. The aniline blue stained tissue of alga E. denticulatum showed that at all TPT concentration tested, the cortex had morphological changes, even almost disappeared at higher concentration (>20μgl^<-1>). The medullary cells of alga exposed to 5-15μgl^<-1> have been decreasing in size compared to those in control. Cell walls of some medullary cells have damaged at 20μgl^<-1> and totally lysed in all cells of alga exposed to 25 and 30μgl^<-1>. The pattern of zonatedly dividing tetrasporangium had not occurred anymore in alga exposed to TPT even at the lowest tested concentration (5μgl^<-1>) and had totally damaged in higher concentrations, such as that of 20μgl^<-1>. The tetraspores in tetrasporangium seem to be fused or shrinkage, no more dividing process occurred as in control. Therefore, reproductive cells of alga is more sensitive than somatic cells, indicating that no further development of alga will occur in aquatic environment contaminated even with unlethal TPT levels.
