Veggies from Ya­muna flood­plains may be toxic

Consumer Voice - - In The News -

Con­sump­tion of crops grown along the Ya­muna can lead to se­ri­ous health im­pli­ca­tions due to heavy metal poi­son­ing, a study by Tox­ics Link, an en­vi­ron­men­tal re­search and ad­vo­cacy or­ga­ni­za­tion, has found. Ac­cord­ing to the study, the pres­ence of heavy met­als such as lead, chromium, ar­senic and mer­cury have been found in sed­i­ment sam­ples at the river. “All the de­tected heavy met­als are known to cause se­ri­ous health im­pli­ca­tions, so stan­dards have been pre­scribed to limit the heavy met­als con­tent in drink­ing wa­ter and food,” the study notes.

While the re­port notes that “there is no spe­cific stan­dard for heavy metal con­tent in the sed­i­ment and soil”, it ob­serves that the level of heavy met­als in the sed­i­ments of the Ya­muna is high. In­ter­est­ingly, the re­port also un­der­lines that the level of heavy metal con­tam­i­na­tion in­creases sig­nif­i­cantly af­ter Wazirabad. This may be due to the dis­charge of waste wa­ter into the river from var­i­ous canals and drains.

The study tested the ‘Tox­i­c­ity Load of Ya­muna River in Delhi’ and ex­am­ined the pH, tur­bid­ity, solids, and heavy met­als in wa­ter and sed­i­ments of the river. The sam­ples were col­lected from dif­fer­ent lo­ca­tions in Delhi (be­fore and af­ter Wazirabad) dur­ing pre- and post-mon­soon sea­son.

“The re­sults in­di­cate high con­cen­tra­tion of tur­bid­ity and to­tal solids at both be­fore and af­ter Wazirabad lo­ca­tions,” the study states. Apart from rais­ing aware­ness about the is­sue and us­ing tech­nol­ogy to de­con­tam­i­nate the river, the study also rec­om­mends map­ping out the sources of pol­lu­tion and re­me­dial mea­sures to ‘de­con­tam­i­nate the river bed’ of heavy met­als.
