WebBOD. BOD value in the studied area varied between 1.6-3.5 mg/L. All sampling points showed BOD values within the prescribed limit by WHO. Ground water with high value of BOD is due to microbial activities related to the dumpsites. Conductivity. Electrical conductivity (EC) of water is a direct function of its total dissolved salts 23.

Linear re gression coefficients for all SIC categories except two (SIC 25 and 73) are statistically signifi cant at the 99% level. Five may prove of practical significance (SIC 26, 28, 33, 35, 36), while the r values for SIC 20, 34, and 72 indicate no linear relationship of practical value between bod and cod. In ... WebHigh COD / BOD levels also decrease the amount of dissolved oxygen available for aquatic organisms. Low (generally under 3 mg/L) levels of dissolved oxygen, or “hypoxia,” causes reduced cell functioning, disrupts circulatory fluid balance in aquatic species and can result in death of individual organisms [iii] , as well as large “dead zones” in the waterbody. traeger clock
