Sensitive microbiological detector for air pollution.

摘要: THERE is an extensive literature on the photochemical reactions involved in production of smog, which reviewed refs. 1. and 2. Early investigations this problem3–5 revealed that at extremely low concentrations oxidative constituents could damage leaves certain plants, differences leaf plants specified stages their development be used to characterize various types smog oxidants6–8 Went9 contrasts vulnerability photosynthetic cells a leaf, must operate by gaseous diffusion very carbon dioxide gradients between free air cell contents, with relatively protected position corresponding human respiratory system. He points out advantages exploiting sensitivity plant give warning tolerance levels pollution are being exceeded.
