Typical economic activities reveal variations in microplastic pollution and ecological risks in the environment.

Microplastic pollution and ecological risks vary significantly across economic activity environments, with landfill and Yellow River Basin areas showing higher MP abundance and risks.

• Why it matters: Understanding how economic activities influence microplastic distribution is crucial for developing targeted pollution control strategies and protecting ecosystems from emerging contaminants.
• What they did: The study analyzed microplastic occurrence in multiple media from diverse economic environments, using indices like PLI, PHI, and PERI to assess environmental risks, with over 160 particles/kg in soil and 1.61 particles/L in water.
• The result: Findings reveal that pollution levels are linked to socioeconomic factors and that urbanized areas pose higher ecological risks, especially from toxic polymers, informing better management and prevention efforts worldwide.
