Environmental quality assessment in central Andean Rivers: Using the ecological thresholds concept, environmental quality standards, and biotic indexes [PDF]

River Research and Applications, 2021
AbstractAs in many other countries, Peru has the Water Quality Standard (WQS) as the primary tool for managing and diagnosing water resources. An analysis of variable by variable was applied to define water quality as poor or good by setting concentration limits.

The enhancement of infrared light on degradation of trimethoprim

Catalysis Communications, 2021
In this study, hydrogenated tungsten oxide(WO3-x) was synthesized. Through experiments, it was found that the material could effectively use infrared light to generate free radicals and effectively remove trimethoprim(TMP).

Urban Flood Analysis in Ungauged Drainage Basin Using Short-Term and High-Resolution Remotely Sensed Rainfall Records

Remote Sensing, 2021
Analyzing flooding in urban areas is a great challenge due to the lack of long-term rainfall records. This study hereby seeks to propose a modeling framework for urban flood analysis in ungauged drainage basins. A platform called “RainyDay” combined with

Remote sensing-based spatiotemporal variation and driving factor assessment of chlorophyll-a concentrations in China’s Pearl River Estuary

Frontiers in Marine Science, 2023
Climate change and intensive anthropogenic activities have severely challenged the water quality of China’s Pearl River Estuary (PRE). Further investigations into long-term water quality variation and associated driving mechanisms are therefore necessary
