Abstract Lead inhibits respiration and photosynthesis in Phaeodactylum. In cells treated for 24 h with PbCl2 (10 mg 1−1), photosynthesis is completely suppressed, while respiration is reduced to 25%. A lower concentration, 1.0 mg 1−1, permits photosynthesis at 75% of the control rate, respiration being virtually unaffected. The vital activities of cells treated for 48 h or 72 h are progressively more inhibited: concentrations of PbCl2 as low as 0.1 mg 1−1 reduce photosynthesis and respiration by 25 to 50%.
