Why Pcb have lasting effect than nitrate in the aquatic habitat.
PCB bind to soil and other particles in the water but only small amounts will dissolve in water. Small concentrations of PCBs can also evaporate and be carried long distances in the air. PCB stay longer in the soil and sediments more than nitrate.
When PCB is inside the ocean or aquatic environment,the fish or water organisms will absorb it from the water and sediments in their habitat. Too much accumulation of it can lead to their death and when such aquatic organisms are consumed, it will prone bad health to humans and even foetus.
