Clustering micropollutants and estimating rate constants of sorption and biodegradation using machine learning approaches

open access: yesnpj Clean Water, 2023
Effluent from wastewater treatment plants is considered an important source of micropollutants (MPs) in aquatic environments. However, monitoring MPs in effluents is often inefficient owing to the variety in their types.
