Question 2: Would lead (Pb) be a imitating factor for the fungi’s ability to bioremediate the soil contamination?

Question 3 : Monitorig studies showed that several schools in Harlem and the Bronx have heavy metal contamination in the soils surrounding the school. Do you think it could be a matter of environmental justice ?

Lead is quite toxic from very low dose, in developing children but also in adults. A recent study looked at two indigenous fungal strains from mine trailings, as potential tools for bioremediation of heavy metal polluted aras. he figure below shows the reduction of Lead by the 2 fungal strain. To simplity, the reduced form is the most toxic to humans. 0 0012x+36.375 3 2 2 Y0.003x+13.949 ..?20.9724 * . 000 900 800 700 600 500 400 300 200 100 0 Question 1: How would you call this type of bioremediation? which of the 2 tested fungi seems to be the most promising in the above lab testing? 0 2

Explanation / Answer

1) With the growth of industries, there is a considerable increase in discharge of heavy metal in the environment (soil, water). This bioremediation is called mycoremidiation because fungi based technology is used to decontaminate the environment. Fungi using the absorption phenomenon to remove lead from the soil. TA is most prmomising because cause reduction at slower rate so less reduced form available whereas MC has heigher reduction rate so produced more reduced form and that is toxic to human.

3) Yes , it could be a matter of environmental injustice. heavy metal contamination surrounding the school could affect the environment surrounding the school that ultimately affect the health of school children. pregnant Female residing in that area also have exposure to this heavy metal and giving birth to the baby with developmental disorders.This particular area has disproportionate share of pollution.

2) Yes, lead act as imitating factor for the fungi ability to bioremediate the soil contamination. bioremediation depend upon type of metal and its availability in the soil.
