• Farming activities can bring detected emerging pollutants to environment and biota. • Existing farms’ wastewater treatment systems showed ineffective removal of phenols. • Higher level of 4-HAP in cultivated biota mainly came from feeds and farming water. • Consuming 4-HAP contaminated Penaeus vannamei will induce higher risks to females. • Conceptual strategic framework was proposed to mitigate ecological and health risks. Emerging contaminants are increasingly and ubiquitously found in both aquatic and terrestrial farms. However, their sources poorly understood, which results in limited capacity to manage and control the ecological and human health risks. The targeted pollutants such as hormones, antibiotics, and phenols were analyzed in farming water, surrounding rivers, feed, biota and feces in the present study. In farming water, the phenols were more prevalent contaminants in aquatic farms, whereas antibiotics were predominant in terrestrial farms, which was partially attributable to the distribution of targeted pollutants in used feed. Notably, the sewage treatment system of terrestrial farms effectively reduced hormones (removal rate: 98.38%) and antibiotics (removal rate: 91.98%), but showed poorly in removing phenols, with their concentrations actually increasing by 37%. This raised significant concerns, as phenols from treated wastewater into rivers posed a threat to aquatic organisms such as fish and daphnia. Moreover, daily pollutant exposure was higher for fem...
