Suspension of the algae treated with (C₆H₅)₃SnCl at concentrations of 1.0 and 4.0 micro mol dm^-3 for 22 h revealed a decrease in most physiological parameters studied, particularly in decasecond component of delayed chlorophyll luminescence, photosynthetic electron transport rate and diluted oxygen concentration, which implies an inhibition of photosynthetic electron transport as well as oxygen evolving system. On the other hand, (C₆H₅)₃PbCl caused stronger inhibition than (C₆H₅)₃SnCl, particularly in the higher concentration. 收起
