Question

how mant times greater is the concentration of DDT in the fish then seawater? how many times greater is it in the dolphins then sea water?

here is your info: fish is 43 ppb, (parts per billion), seawater is 0.0001 ppb, dolphons is 5200 ppb.

sorry for the spelling. it is ppb not ppm

Answer 1

43 ppb / 0.0001 ppb = 430,000 times or 4,300%

5200 / 0.0001 ppb = 52,000,000 times or 520,000%
