 Environmental concentrations can exceed adverse @-@ effect @-@ thresholds in cadmium @-@ polluted ecosystems ( e.g. in some parts of Europe ) and pollutant cadmium can accumulate in invertebrates , earthworms , seabirds , marine mammals , plants , and some algal species ; effects in animals include kidney disorders , impairment of enzymes , disruption of calcium metabolism , and changes in cell membrane permeability ; excess Cd uptake in plants can affect growth and metabolic processes such as photosynthesis and transpiration .
