Characterizing the fate and transport of chemicals of emerging concern (CECs) from swine manure during waste to energy processes
Animal manure and domestic wastewater contain chemicals of emerging concern (CECs) that can threaten ecosystems and human health. For instance, estrone (E1) and 17β-estradiol (E2) can disrupt the reproductive biology of vertebrates at very low concentrations. This study investigates the effects of …
