Anthracene phytotoxicity in the freshwater flagellate alga Euglena agilis Carter

The freshwater flagellate alga Euglena agilis Carter was exposed to the polycyclic aromatic hydrocarbon (PAH) anthracene for 96 h under optimal photosynthetically active radiation (PAR), and responses of growth, photosynthetic pigment production, and photosynthetic efficiency were assessed. Anthracene reduced the growth rate (μ) and levels of chlorophyll a (Chl a ), chlorophyll b (Chl b ), and total carotenoids. The growth rate was more...
