This computer-generated nanoscale view of liquid water is from the lab of Gene Stanley of Boston University .
2.3 To what extent do PCBs break down or persist in the environment? Some PCBs tend to be more persistent in the environment than others. The extent to which a PCB molecule can be broken down or transformed depends on the number of chlorine atoms it contains and where they are located. PCBs are mainly broken down either by the effect (direct or indirect) of sunlight or by microorganisms.
