Carryover of cadmium from feed in growing pigs.

Growing male pigs were exposed to cadmium (Cd) at levels around 1 and 10 mg kg(-1) feed for up to 12 weeks, administered as CdCl2 or Cd-cysteine (CdCys). Pigs exposed to 10 mg kg(-1) showed decreased growth during the last 3 weeks. Liver and kidney concentrations of Cd continuously increased over the entire 12-week exposure, exceeding the European Union limits of 1.

Toxicity, accumulation, and retention of zinc by carp under normoxic and hypoxic conditions.

Zinc is an essential micronutrient that becomes toxic at elevated concentrations. Under hypoxic events, i.e.

The toxicokinetics of cadmium in carp under normoxic and hypoxic conditions.

Temporal depletion of oxygen, i.e. hypoxic events, frequently occurs in natural waters.

Uptake, biotransformation, and elimination of 99Tc in duckweed.

Aquatic plants may play an important role in the environmental fate of the long-lived radioactive waste product 99Tc. Aquatic plants show a strong accumulation and retention of Tc, even after they have died. This study focuses on possible bio-organic Tc compounds formed in the water dwelling plant duckweed to possibly explain the accumulation and retention.
