Wastewater-based estimation of diabetes mellitus prevalence in 237 cities: A cross-China study.

Diabetes mellitus, a metabolic disease characterized by hyperglycemia, has been witnessed as a rapidly escalating worldwide health crisis. China currently had 140.9 million diabetic population in 2021, which was the largest globally.

Estimating the prevalence of dyslipidemia by measuring fenofibrate in 33 cities in China.

Dyslipidemia, recognized as a predominant risk factor for atherosclerotic cardiovascular disease (CVD), remains a pressing health concern worldwide, particularly in China with nearly 40 % of the population adversely suffering. Fenofibrate, as one of the most commonly used drugs for dyslipidemia therapy, excreted as the format of fenofibrate-acid, which showed considerable stability in sewage samples and could be detected as WBE-biomarkers to monitor the prevalence of dyslipidemia. In this work, we reported the first research on estimating the prevalence of dyslipidemia by WBE approach.

Sensitive determination of 11-nor-9-carboxy-Δ9-tetrahydrocannabinol in wastewater by solid-phase extraction with pre-column derivatization and liquid chromatography-tandem mass spectrometry.

As the dangers of cannabis abuse draw attention worldwide, it is necessary to assess the level of consumption in the community. The analysis of 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THC-COOH) excreted in wastewater can provide information for a defined catchment area. Due to its hydrophobic nature and absence of ionizable groups, its detection is challenging.
