The effect of the organometallic compounds containing lead, (C6H5)3PbCl , and tin, (C6H5)3SnCl, on Chlorella green algae photosystem II was studied. Suspension of the algae treated with (C6H5)3SnCl at concentrations of 1.0 and 4.0 micromol 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.
研究了含铅的有机金属化合物（C6H5）3PbCl 和锡的有机金属化合物（C6H5）3SnCl 对绿藻光合作用系统 II 的影响。用浓度为 1.0 和 4.0 微摩尔/分升的（C6H5）3SnCl 处理藻类悬浮液 22 小时后，发现大多数研究的生理参数下降，特别是延迟叶绿素荧光的十秒成分、光合电子传递率和稀释氧浓度下降，这意味着光合作用电子传递以及氧释放系统受到抑制。另一方面，（C6H5）3PbCl 引起的抑制作用比（C6H5）3SnCl 更强，特别是在较高浓度下。
