Effects of polyethylene terephthalate

Effects of polyethylene terephthalate (PET) microplastics and acid rain on physiology and growth of Lepidium sativum

This study has highlighted, for the first time, that different size of polyethylene terephthalate (PET), alone and coupled with acid rain is able to negatively affect plant metabolism. The lower size of PETs, have affected, worse the biometrical plants response; while PETs coupled with acid rain have evidenced and higher production of Chl-b at expense of Chl-a, which in turn results in a lower production of this latter pigment. Always at tetrapyrroles pathway level, this latter treatment had totally inhibited aminolevulinic acid production.
