     The aim of this tesearch was to analyzed the arnount of heavy metals in the water of Songkhla lirke. Nine samples of water were collected lrom nine communities and industrial plants. The samples were analyzed for the quantity of heavy nretals using atomic absorption spcctrophotonletry method, ie.direct aspiration technique for determination of copper, lead, zinc and n)anganese, cold vapour tcchnique tbr dererminarion of melculy, andhydridc generation teclrnique for derermination of selenrum.
       The findings revcaled that tlrer e were copper, leld, zinc, mangancse. rnercury and selenium rangtng between 0.003-0.020. 0-0.10, 0.03-0.06, 0.05-0.51, 0-0.005 rnd 0.01 l-0.02? ppm. rcspcctrvely.
