Effective river water quality monitoring is essential for sustainable water resource management. In this study, we established a comprehensive monitoring system along the Kaveri River, capturing real-time data on multiple critical water quality parameters. The parameters collected encompassed water contamination levels, turbidity, pH measurements, temperature, and total dissolved solids (TDS), providing a holistic view of river water quality.

- Fine particulate matter (PM) from gasoline-fueled vehicles is a major air pollutant that poses risks to health and urban air quality, making its chemical composition critical for understanding climate change and pollution control.
- The study focused on PM emissions from 15 vehicles, analyzing the chemical makeup, including carbon components (organic carbon and elemental carbon) and metallic elements like calcium and iron.
- Using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), researchers found that elemental and organic carbon were the most prevalent types of carbonaceous species in the PM emissions.
Article Synopsis
- * Researchers sampled fifteen different vehicles to measure concentrations of sixteen priority PAHs, considering the various Euro emission standards established by European legislation.
- * The findings revealed that the average total PAH concentration in the emissions was 0.377 ng/L-fuel, with a specific concentration for benzo[a]pyrene equivalent (BaPeq) at 0.00993 ng/L-fuel, indicating significant health risks from gasoline exhaust exposure.
This research investigates the mileage and the health risk assessment of aerosol carcinogenicity and mutagenicity emitted by ten in-use motorcycles. The total p-PAHs emission factor of ten in-use motorcycles are 676.3 μg km with average of 67.
