A Physico Chemical Assesment on Microbial Pollution of Yamuna River: a Case Study of Delhi |

Swati Tyagi, in Journal of Advances in Science and Technology | Science & Technology


Present study manages an appraisal of some Physicochemical parameters of the Yamuna River at Mathura. The study territoryencounters a regular atmosphere and comprehensively partitioned into threeseasons as winter (November to February), Summer (March to June) and blustery(July to October). The examples were gathered and investigated for two sequentialyears 2011 and 2012. Examination of some physico-chemical aspects like, watertemperature, ph, D.o. (mg/L), BOD (mg/L), C.o.d. (mg/L), and T.d.s. (mg/L) hasbeen carried out amid the examination period. The water ph of river ran from abase 7.2 and 8.3 in summer D.o 3.0 to 10.4 in winters B.o.d. 14.0 to 52.7 insummers and C.o.d. 11.4 to 35.2 in winters while as T.d.s. 460 to 553indownpours. Customarily, the river pollution has been broadlycontemplated as to physical and chemical attributes. Then again, recentlymicrobiological nature of the river has gone under more prominent center owingto injurious impacts of pollution on human health, particularly in theconnection of Designated Best Use (DBU) of the river waters. With this purpose,the paper presents pollutional parts of river Yamuna at Delhi, the capital ofIndia, amid lean the period. Out of huge number of microbial parametersconnected with human health, some noteworthy sullying pointers, specifically,heterotrophic plate check (absolute plate number, CFU/ml), downright coliform(MPN/100 ml), Fecal Coliform (MPN/100 ml), pathogenic parasites, in particular,Helminths (eggs/l), coliphages/100 ml have been distinguished and measuredalongside the related regular parameters, specifically, disintegrated oxygen(ppm), biochemical oxygen request (ppm), chemical oxygen request (ppm), ph,temperature (0c), aggregate broke up solids (ppm) and turbidity (NTU). Sixinspecting areas (extension locales) were chosen and aggregate 24 example setswere gathered over a time of four months from March 2004 to June 2004. The high estimations of microbial pointers and pathogenslocated uncovered that the microbiological nature of Yamuna waters was poor,perilous and not adequate even for the most reduced DBU. The consequences ofthe study have uncovered the requirement for pollution decrease measures toguarantee river water quality according to the prerequisite of DBU. Further, anendeavor has been made for producing the fast technique for estimation oforganic pollution and comparing microbial pollution, amid Delhi stretch ofYamuna river, through determined connections, specifically, Chemical oxygenrequest (COD, mg/l) and Fecal Coliform (FC, MPN/100ml). The consequences ofFecal Coliform acquired by lab examination might be confirmed by looking at theresults got from different between connections explored in this study. The copyexamination or utilization of control tubes might be dodged in standardmicrobial dissection.
