[Distribution Characteristics of Antibiotic Resistance Genes in PM of a Concentrated Broiler Feeding Operation].

Concentrated poultry feeding operations are an important source of antibiotic resistance genes (ARGs). Little attention has been given to PM as a mechanism for exposing ARGs to humans. In this study, PM and fecal samples from inside the broiler feeding operation and PM samples from outside the broiler feeding operation were collected.

Impacts of emerging contaminants on surrounding aquatic environment from a youth festival.

The youth festival as we refer to Spring Scream, a large-scale pop music festival, is notorious for the problems of drug abuse and addiction. The origin, temporal magnitudes, potential risks and mass inputs of emerging contaminants (ECs) were investigated. Thirty targeted ECs were analyzed by solid-phase extraction and liquid chromatography coupled to tandem mass spectrometry (SPE-LC-MS/MS).
