Environmental concentrations of metals (Cu and Zn) differently affect the life history traits of a model freshwater ostracod

The European Zoological Journal
Zinc (Zn) and copper (Cu) are common contaminants of inland water bodies under severe anthropogenic pressure. The main aim of this study was to test the influence of environmental aqueous concentrations of Zn and Cu on the fitness-related life history ...

Bioconcentration Factor (BCF) and Translocation Factor (TF) of Heavy Metals in Mangrove Trees of Blanakan Fish Farm

Makara Journal of Science, 2017
In the mangroves of Blanakan, Indonesia, silvofishery practices may play a role in maintaining the environmental quality of ponds. Mangroves are known as pollutant traps since their root systems absorb and accumulate materials.
