Chemical Contamination of Water Supplies [PDF]

open access: yesEnvironmental Health Perspectives, 1985
Man-made organic chemicals have been found in drinking water for many years. Their numbers and varieties increase as our analytical capabilities improve. The identified chemicals comprise 10 to 20% of the total organic matter present. These are volatile or low molecular weight compounds which are easily identified.

Ultraviolet absorption of contaminants in water [PDF]

open access: yesScientific Reports, 2021
AbstractContaminants in water were studied using ultraviolet absorption with light emitting diode and deuterium lamp sources, and a thresholding detector. The absorption spectra of potassium hydrogen pthalate, clothianidin, tryptophan, thiamethoxam, uric acid and metaldehyde were obtained in the range 200–360 nm.
