We report here the effects of cadmium on metabolome macroalga Gracilaria caudata. The IC50 3 mg/L (12 µM) was obtained after 48 hrs exposure and induced lower photosynthesis efficiency. Threshold concentrations determined by Brazilian Environmental Council (CONAMA) in marine waters (0.04 mg/L) effluent discharge (0.2 were also tested, latter changed photosynthetic efficiency similarly to IC50. ...

This study aimed to analyze minerals (Ca, Mg, Fe, Zn, Mn and Cu) heavy metals (Pb Cd) content of seaweeds collected from coastal waters Bangladesh using Atomic Absorption Spectrophotometer (AAS). Eight wild species in three phyla viz. Rhodophyta (Hypnea sp.), Chlorophyta (Enteromorphasp.),and Phaeophyta (Sargassumsp.,Hydroclathrusclathratus, Padinapavonica, Colpomeniasinuosa, Petalonia fascia D...
