为解决再生塑料中潜在致癌物多环芳烃(PAH)污染问题，研究人员系统评估了LDPE、HDPE、PET和PP等常见再生塑料的PAH含量。通过优化提取方法，发现PET样品PAH含量最低(<120 ng/g)，而黑色LDPE样品高达2200 ng/g，毒性当量达68 ng TEQ/g。该研究揭示了工业清洗工艺对持久性 ...

微塑料污染对土壤微生物群落及降解能力的影响研究。通过分析LDPE和HDPE微塑料在土壤中的微生物群落多样性、组成及降解潜力，发现LDPE初期微生物多样性较低但随时间显著增加，而HDPE保持较高且稳定的多样性。关键降解菌包括Stenotrophomonas maltophilia和Bacillus ...
