BOD5 AND TOC AT RIVER CROSSINGS, EAST-COAST HIGHWAY, PENINSULAR MALAYSIA
This paper evaluates the Biochemical Oxygen Demand (BOD5) and Total Organic Carbon (TOC) levels at river crossings due to East-Coast highway development. High concentrations of organic contents in the aquatic environment contribute to river water pollution. Thirty three samples were collected at the selected river crossings along the East-Coast Highway. Results showed that there was no significant linear relationship between BOD5 and TOC. Results from the t-test indicated that the construction of the East-Coast Highway has a negative impact as shown by BOD5. The results suggested that more samples should be collected over a longer duration to establish a more reliable relationship between the two parameters.
