Multifunctional Periphytic Biofilms: Polyethylene Degradation and Cd²⁺ and Pb²⁺ Bioremediation under High Methane Scenario.

ABSTRACT: Priority pollutants such as polyethylene (PE) microplastic, lead (Pb²⁺), and cadmium (Cd²⁺) have attracted the interest of environmentalists due to their ubiquitous nature and toxicity to all forms of life. In this study, periphytic biofilms (epiphyton and epixylon) were used to bioremediate heavy metals (HMs) and to biodegrade PE under high (120,000 ppm) methane (CH₄) doses. Both periphytic biofilms were actively involved in methane oxidation, HMs accumulation and PE degradation. Epiphyton and epixylon both completely removed Pb²⁺ and Cd²⁺ at concentrations of 2 mg L^-1 and 50 mg L^-1, respectively, but only partially removed these HMs at a relatively higher concentration (100 mg L^-1).
