Field study of pollutants discharged from non-point sources to a natural water channel. A characteristics of discharge of non-point source was tested using data from natural streams in rainfall runoff. Rainfall run-off samples were collected from river. The water surface, water velocity, discharge, COD and SS were measured. COD and SS loads were determined for rural areas of watershed using measured concentration and runoff volumes estimated by the load of non-point source. The run-off of hydrological and pollutants from non-point source were tested on the study site of I-sa River and its major tributaries. The results of the field study were analyzed and presented in this paper.

Kinetics of pyrolysis of polyethylene, polypropylene, and a mixture of polyethylene and polypropylene(1:1) was studied in the range of 10~90% conversion. Reaction order of them was first order, and activation energies were 255.2, 211.3, 232.5kJ/mol, respectively. Liquid effluent rate of polypropylene was superior to it of polyethylene and a polyethylene - polypropylene mixture(1:1).

Kwangyang Bay is a semi-enclosed coastal basin and one of quickly developing areas in Korea. Many industrial complexes have been established along the bay, producing iron steel, fertilizer and particularly petroleum chemicals. In this study source and occurrence of volatile organic compounds(VOC) were studied at streams, wastewater treatment works and surface water of the bay during July 1996 and April 1997. The principal fate processes of VOC are advection-diffusion, volatilisation and adsorption onto sediments. A mathematical model is developed to investigate the fate of benzene as a target VOC, Simulation resulted in good agreement with measurements.
