This study investigated how polypropylene microplastics affect carbon dioxide dynamics in mangrove sediments. Researchers found that microplastic contamination altered organic carbon content and microbial communities, influencing CO2 release patterns differently depending on tidal elevation and microplastic concentration.
Microplastics (MPs) in soil can influence CO dynamics by altering organic carbon (OC) and microbial composition. Nevertheless, the fluctuation of CO response attributed to MPs in mangrove sediments is unclear. This study explores the impact of micro-sized polypropylene (mPP) particles on the carbon dynamics of intertidal mangrove sediments. In the high-tide level sediment, after 28 days, the cumulative CO levels for varying mPP dosages were as follows: 496.86 ± 2.07, 430.38 ± 3.84 and 447.09 ± 1.72 mg kg for 0.1%, 1% and 10% (w/w) mPP, respectively. The CO emissions were found to be increased with a 0.1% (w/w) mPP level and decreased with 1% and 10% (w/w) mPP at high-tide level sediment, suggesting a tide level-specific dose dependence of the CO emission pattern in mangrove sediments. Overall, results indicated that the presence of mPP in mangrove sediments would potentially affect intertidal total CO storage under given experimental conditions.
