1] in the treatment with higher content of potassium fluoride in the simulated rain (20 mg [L.
The analysis of the chlorophyll a fluorescence showed that before the beginning of the simulations (day 1), there was no effect of potassium fluoride concentration on fluoresce parameters (qN: F = 0.
has potential to be used as a biosensor of air pollution by fluoride, since it presented no visual symptoms when exposed to potassium fluoride and the pollutant accumulation was relatively low and just occurred for the higher concentrations of KF.
Leaflets of Vitex polygama exposed to different concentrations of potassium fluoride in the simulated rain, during 10 days.
1] MS) in plants of Vitex polygama exposed to different concentrations of potassium fluoride (0, 5, 10, 15 and 20 mg [L.
They were noted with Sulfamic Acid, Sodium Nitrite and Sodium Palmitate only at the high concentration, but at both temperatures, while with Potassium Fluoride and Sodium Gluconate, they were noted at both concentrations but only at the high temperature.
5 at low concentration with both aging temperatures), Potassium Fluoride, Sulfamic Acid, Sodium Nitrite and Triethanolamine Borate had TAN between 0.
Potassium Fluoride had TOA > 1000 ppm at the low concentration and high temperature.
For chemicals such as Potassium Fluoride at the high temperature and both initial concentrations, Sulfamic Acid and N-Nitrosodiphenylamine at the high concentration and both temperatures, and Sodium Palmitate at low concentration and low temperature, extraneous peaks (different from the peaks belonging to the chemicals) were detected after aging, indicative of the formation of reaction products.
