What is it about?
The research team inspected the spatial distribution, ecological hazards, and identified the sources evaluation of health risks posed by polycyclic aromatic hydrocarbons in the Ramsar coastal wetland near an urbanized area .The research team surveyed the spatial distribution, ecological hazards, and sources during the study.

Why is it important?
The investigation revealed that nearly all sediment samples contaminated by PAHs exceed the USEPA’s proposed ingestion route threshold (10⁻⁶), showing substantial cancer risks. The non-carcinogenic hazard index (HI) evaluation suggests that ingesting sediments from the wetland can lead to non-cancer risks for both adults and children.
Perspectives
This study comprehensively evaluates the contamination of polycyclic aromatic hydrocarbons (PAHs) in sediment from the Ramsar wetland in Ashtamudi, detailing their concentrations, spatial distribution, composition profiles, ecological and human health risks, and source apportionment.
