Secondary pollutants found in photochemical smog can damage and weaken crops and decrease yield, making them more susceptible to insects.

光化中的二次污染物损害并削弱农作物， 减少产，使其更易受虫害袭。

The infrared radiation emitted from a mammalian body has low quantum energy, which makes any photochemical effect on a pigment extremely unlikely.

哺乳动物身体发出的红外辐射具有较低的，这使得对颜料产生任何光化效应的可性极小。
