TL;DR: High acidity caused by nitric acid and relatively low ion strength are observed in the fogwater at high elevation sites in the Tanzawa Mountains of Japan.

TL;DR: Fogwater chemistry has been observed at Mt. Oyama abutting on the Kanto Plain in Japan as discussed by the authors, and the concentrations of fogwater components were dominated by the absorbing rates of air pollutants into the fog droplets and were not inversely proportional to the LWC.

TL;DR: The amount of microcapsules accumulated in Japanese paddy fields, as estimated from the results, and the amount applied to the fields, were almost equivalent, suggesting that most of the micro Capsules that have already been applied to paddy field may continue to accumulate.

TL;DR: Temporal and spatial variations in concentrations of particle-associated polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives (nitro-PAHS and oxy-PAHSs) were investigated to assess the influence of secondary formation on atmospheric occurrences of oxy PAHs associated with particulate matter in downtown Tokyo, Japan as discussed by the authors.

TL;DR: In this paper, the degradation of concrete structures caused by acid deposition was investigated by laboratory and field exposure of portland cement mortar specimens to acid deposition, and the acid neutralization progressed more deeply in mortar specimens sheltered from rainwater than in those washed by rainwater.
