Expert Solution
Step 1
Methyl mercury levels higher than 3.00×10-4 mg/dL are toxic to central nervous system. Whether the given levels of methyl mercury are life threatening or not is to be determined-
1. 50 µg/L
- 50 cg/mL
Step 2
- Convert the unit µg/L into mg/dL
1 µg = 0.001 mg
1 L = 10 dL (decilitres)
Step 3
Thus, 2.50×10-4 mg/dL < 3.00×10-4 mg/dL.
Hence, 2.50 µg/L levels of methyl mercury is not life threatening.
