Plastic has been an environmental pollutant far longer than claimed by the first reports surfacing in 1979, meaning some plastic materials have decaying nature for decades. Nevertheless, threat posed to biota is not fully understood, especially from aged microplastic. The question considered this study was whether adverse effects of new differ those old material. Therefore, morphological and physiological on Lepidium sativum with exposure both polycarbonate were against a known stressor leaching time, bisphenol-A. Exposure short-term (up 80 days) elicited most severe such as germination inhibition, reduced seedling growth, decreased chlorophyll concentrations, increased catalase activity. These L. associated function ageing time applied polycarbonate. chemical substances that lend material its toxicity likely leached during process. Based results obtained, temperature humidity based artificial significantly phytotoxicity microplastic particles.
