Chemical Leaching from Tire Wear Particles with Various Treadwear Ratings
International Journal of Environmental Research and Public Health, 2022 Physical friction between a tire and the road surface generates tire wear particles (TWPs), which are a source of microplastics and particulate matter. This study investigated the trends of chemical leaching from TWPs depending on the treadwear rating of the tire.

Comparison of nitrification inhibitors to restrict nitrate leaching in a maize crop irrigated under mediterranean conditions [PDF]
, 2010 The aim of this paper was to compare dicyandiamide (DCD) and 3,4 dimethylpyrazole phosphate (DMPP) as inhibitors of ammonium oxidation and nitrate leaching after applying fertilizer to a maize (Zea mays L.) crop grown under Mediterranean conditions.

Temperature Effect on Plutonium Leach Rate of Nuclear Waste Glass [PDF]
Journal of Nuclear Science and Technology, 1989 The two kinds of nuclear waste glass with similar composition, a 238Pu-doped and non-radioactive waste glass, were leached under the ISO-test conditions at temperature between 23 and 90°C. An activation energy of 22±10 kJ/mole was obtained from the initial leach rates of Pu, which was much lower than the 78±9 kJ/mole obtained from those of Si, Na, Sr ...

Review of key causes and sources for N2O emmisions and NO3-leaching from organic arable crop rotations [PDF]
, 2018 . The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) have considerable negative impacts on climate and the environment. Although these environmental burdens are on average less per unit area in organic than in non-organic production, they
