Comments on: Harvesting Toxins http://www.damninteresting.com/harvesting-toxins A collection of Damn Interesting things Wed, 17 Mar 2010 00:31:54 -0700 http://wordpress.org/?v=2.9.1 hourly 1 By: peace http://www.damninteresting.com/harvesting-toxins#comment-25721 peace Tue, 02 Feb 2010 21:19:24 +0000 http://www.damninteresting.com/?p=430#comment-25721 I didnt understand if phytoremediation using agricultural crops is suitable for removing heavy metals from the contaminated soil or not because all the metals are accumulated in crop. but still many reserchers are using them in phytoremediation. If agricultural crops can be used for phytoremediation then what will be done for disposal of harvested plant parts. Please experts in this field answer my query… I didnt understand if phytoremediation using agricultural crops is suitable for removing heavy metals from the contaminated soil or not because all the metals are accumulated in crop. but still many reserchers are using them in phytoremediation.

It’s more useful to render the contaminants harmless, but being able to recover useful soil is in and of itself a tremendous accomplishment. Don’t underestimate the value of a more convenient vessel when you’re talking about things as toxic as radioactives and heavy metals."[/quote] I didnt understand if phytoremediation using agricultural crops is suitable for removing heavy metals from the contaminated soil or not because all the metals are accumulated in crop. but still many reserchers are using them in phytoremediation.

I'm thinking that a large portion of that 30,000 are in the nevada/utah/AZ deserts. Good lukc growing trees or mushroom in the environment. [quote]Mirage_GSM said: “Actually… No.
