Daniel Harris has always enjoyed eating tuna fish. Unfortunately, a study of the mercury content of canned tuna in 2010 found that chunk white tuna contains 0.6 ppm Hg and chunk light tuna contains 0.14 ppm.2 The U.S. Environmental Protection Agency (EPA) recommends no more than 0.1 μg Hg/kg body weight per day. A person weighs 63 kg . How often may the person eat a can containing 6 ounces (16 oz=1 lb) of chunk white tuna so that they do not average more than 0.1 μg Hg/kg body weight per day?
А The person can consume one 6 oz can of chunk white tuna every_______ days.
If the person switches to chunk light tuna, how often can they eat one can?
The person can consume one 6 oz can of chunk light tuna every_______ days.

From the information given:

In 2010, the mercury content of:

  • The mass of chunk white tuna = 0.6 ppm
  • The mass of a chunk of light tuna = 0.14 ppm
  • weight of the body = 63 kg
  • mass of the tuna = 6 oz

It is recommended that the maximum amount of mercury consumed by the body should not be more than 0.1 micrograms per day.

To determine how often may the person eat a can containing 6 ounces of chunk white tuna, we need to go through the following processes:

First, let convert the mass of the tuna to grams

Since 1 oz = 28.3495 g

Mass of the tuna = 6 oz × 28.3495 g

= 170.097 g

The maximum amount of mercury (Hg) permitted to be consumed by a 63 kg body weight in a day = 63 × 0.1

= 6.3 micrograms/day

However, the mass of the mercury (Hg) = concentration (Hg)  × mass of tuna

= 0.6 × 10⁻⁶ × 170.097 g

= 1.0206 × 10⁻⁴ g

= 102.06 μg (micrograms)

Thus, the time required between the consumption of one 6 oz can of chunk white tuna is:

[tex]=\mathbf{ \dfrac{102.06}{6.3}}[/tex]

= 16.2 days

≅ 16 days

The time required between the consumption of one 6 oz can of chunk white tuna is approximately every 16 days.

To determine how often may the person eat a can containing 6 ounces of chunk light tuna, we need to go through the following processes:

However;

the mass of the mercury (Hg) = concentration (Hg)  × mass of tuna

= 0.14 × 10⁻⁶ × 170.097 g

= 2.4814  × 10⁻⁵ g

= 23.814 μg

Thus, the time required between the consumption of one 6 oz can of chunk white tune is:

[tex]=\mathbf{ \dfrac{23.814}{6.3}}[/tex]

= 3.78days

≅ 4 days

The time required between the consumption of one 6 oz can of chunk light tuna is approximately every 4 days.

Therefore, we can conclude that the time required between the consumption of one 6 oz can of chunk white tuna is approximately every 16 days and the time required between the consumption of one 6 oz can of chunk light tuna is approximately every 4 days.
