Soil-biodegradable plastic films do not decompose in a lake sediment over 9 months of incubation

Dataset with the article 'Soil-biodegradable plastic films do not decompose in a lake sediment over 9 months of incubation', containing CO2 and CH4 data of sediment core incubations in a laboratory setting. Time is in days. Group identifiers: PC = control, PE = PE plastics (traditional), PR = Biodegradable plastics type 1, PS = biodegradable plastics type 2.本数据集配套学术论文《土壤可生物降解塑料薄膜在湖泊沉积物中历经9个月培养仍未降解》，包含实验室环境下沉积物岩芯培养实验的二氧化碳（CO₂）与甲烷（CH₄）检测数据，实验时长单位为天。分组标识符定义如下：PC为对照组，PE为传统PE塑料组，PR为1型生物降解塑料组，PS为2型生物降解塑料组。
