Pesticide Remediation/Removal

Baking Soda Washes Pesticides from Apples (By Janet Pelley, for C&EN, 15 NOv. 2017)  'The scientists compared the efficacy of the germicidal bleach to rinsing with tap water or a sodium bicarbonate solution, which is alkaline. “Most pesticides are not stable at an alkaline pH, which breaks down the compounds and helps to wash them away,” she explains.'  The researchers applied two common pesticides, the fungicide thiabendazole and the insecticide phosmet, at concentrations used by farmers. 'Immersing the apples in a sodium bicarbonate solution for 15 minutes followed by a freshwater rinse removed all pesticide residues from the surface of the apples, whereas the tap water and bleach treatments removed some, but not all. Sodium bicarbonate degrades the pesticides, boosting the physical removal force of washing, He says.' However some residue had penetrated the peel and could not be removed.

Oregon Group Uses Mushrooms for Bioremediation (Beyond Pesticides, January 23, 2014)  Using recycled burlap bags filled with used coffee grounds, straw, and yellow oyster mushroom spawn, the purpose of the unusual potpourri will be to harness the extremely effective filtering capabilities of mycelium. “Oyster mushrooms, for example, can digest the complex hydrocarbons in wood, so they can also be used to break down petroleum byproducts. Garden Giants use their mycelia to trap and eat bacteria, so they can filter E. coli from agricultural runoff.” 

Chlorpyrifos residues: Although bombarding chlorpyrifos-contaminated containers with gamma radiation was "efficient for removing chlorpyrifos from the plastic packing," radioactive substances create their own environmental problems from both mining and disposal. Dilute chlorine bleach is a "perfectly viable alternative" effective to degrade chlorpyrifos residuesZapping pesticides with radiation,(Susan Kegley, PANUPS Dec 6. 2007, scroll down)

Study Finds Plants Remove Golf Course Pesticides From Soil   “We have identified plant species that can reduce the amount of certain pesticides in soil by up to 94 percent in the greenhouse.” Blue flag iris reduced chlorpyrifos by 76 percent and levels of chlorothalonil by 94 percent after three months of growth. 1 pants identified including the flag iris.(Beyond Pesticides, June 20, 2008)
