Endocrine-disrupting chemicals in three Aquatic Germplasm Resources National Conservation Zone in the South China Sea: Distribution and Risks

Marine Protected Areas (MPAs) play a crucial role in providing ecological and socio-economic benefits, including biodiversity conservation, habitat protection, climate change resilience, sustainable fisheries, ecological tourism, and educational value. This study specifically delves into three Aquatic Germplasm Resources National Conservation Zones (AGR-NCZ) situated in the South China Sea. The primary focus within these zones encompasses the protection of species such as Panulirus stimpsoni, Ostrea rivularis, and the parent and juvenile populations of economically significant fish species. The study extensively evaluates the pollution levels of 31 endocrine-disrupting chemicals (EDCs) within the AGR-NCZ, categorizing these EDCs into four groups: estrogens, bisphenols, brominated flame retardants and chlorine flame retardants, and parabens. Furthermore, a comparative analysis of pollution levels has been carried out in coastal regions. Moreover, the research assesses the potential ecological risks posed by these EDCs and investigates the associated human health hazards, considering local populations of varying ages and genders. The study examines major exposure pathways such as accidental oral ingestion and dermal contact exposure to illuminate the potential health impacts of these EDCs. The findings of this research offer valuable insights for the management and remediation of emerging pollutants within marine protected areas, contributing to enhanced environmental protection measures.
