Metagenomic insights into microbial communities and antibiotic resistance in treated wastewater for urban irrigation.

ABSTRACT:

Background

The increasing reuse of treated wastewater for urban irrigation globally has raised ecological and public health concerns associated with microbial contaminations, antibiotic resistance genes (ARGs), and pathogen dissemination.

Methods

Using a metagenomic approach, we analyzed microbial communities, ARGs, and pathogen profiles in three types of treated wastewater (W1, W2, W3) used for urban irrigation. Physicochemical properties, including nutrients and heavy metals, were also assessed to identify potential drivers of microbial and resistance patterns.

Results

Significant variations in water quality and microbial community were observed across wastewater treatments. W2 showed the highest nutrient and organic pollution levels, while W3 exhibited elevated hea
