6 6 grams. The fish feed primarily on shrimp, as well as insects and other small animals. You 6.ve learned that an algae that is one of the primary food sources for shrimp in the lake is minated with Mercury. You want to know how much of this Mercury might 4 of 4 natty end up in members of the community. ,-….cunt of mercury in 1 gram of algae = 0.0002 mg Amount of algae 1 shrimp eats in its lifetime = 10 grams of algae
3.1 How much memory did the shrimp eat? 3.2 Since a shrimp weighs I gram, what is the concentration of mercury per shrimp? (hint: your answer should be in mg/g-shrimp)
4. Now, the fish in the lake eat about 1,700 g of shrimp 4.1 How much mercury did the fish eat? 4.2 Since one fish weighs 150 g, what is the concentration of mercury per fish?
5. A person from this community eats 1 fish daily 5.1 How much mercury did the person eat in 1 day? 5.2 How much mercury would the person eat in 30 years?

RISK ANALYSIS LAB
HINTS: Mercury consumed by fish = amount shrimp consumed x concentration of mercury in shrimp Mercury consumed by human = amount fish consumed x concentration of mercury in fish
6. After learning how dangerous Mercury is for the environment and you, what steps can you take to reduce Mercury in the environment?
