Triclosan in the urine of Chinese youth: concentration, temporal variability, sources of exposure and predictive ability.

Triclosan (TCS) is an antimicrobial agent commonly used in personal care products. The assessment of TCS exposure in humans frequently relies on analyzing urinary TCS levels. Consequently, it is crucial to have a comprehensive understanding of the variability of TCS levels in urine.

Association between exposure to persistent organic pollutants and pubertal timing in boys and girls: A systematic review and meta-analysis.

In recent years, the phenomenon of abnormal pubertal timing in children has become increasingly common worldwide. Persistent organic pollutants (POPs) may be one of the risk factors contributing to this phenomenon, but the relationship between them is unclear based on current evidence. The purpose of this study was to determine the association of POPs exposure with pubertal timing in girls and boys by conducting a systematic review and meta-analysis.
