Nanoscale zero-valent iron (nZVI) shows an excellent degradation effect on chlorinated contaminants in soil. but poses a threat to plants in combination with phytoremediation. Arbuscular mycorrhizal (AM) fungus can reduce the phyototoxicity of nZVI. but their combined impacts on polychlorinated biphenyls (PCBs) degradation and plant growth remain unclear. https://pipingrockers.shop/product-category/brewers-yeast/
