- Below is a graph on the fate of bifenthrin within the aquatic environment with various sediments. i. State a hypothesisThe organophosphate Azinphos-methyl has a96-hour LC50 value of 3 ppb for rainbow trout. Inan unfortunate incident, 200 g of this pesticidewas sprayed on a field, and a subsequent heavyrainfall washed 35% of it into a nearby lakehaving a surface area of 30,000 m2and anaverage depth of 0.5 m. Would the pesticideconcentration in the lake water have beensufficient to kill a significant fraction of therainbow trout in the lake?The American Heart Association and other health organizations have concluded that consumers should get their antioxidants from foods rather than supplements. They add that taking supplements may even be harmful. Supplement manufacturers claim that such statements are unfair and that their natural botanical extracts provide numerous health benefits. In fact, some suggest that beneficial effects can only be achieved by taking high-dose supplements. Given that there are currently no DRI defining the kinds of antioxidants or the daily quantities needed, how might you ensure a healthy intake of antioxidants? If you decide to take an antioxidant supplement, how might you research the product to determine its safety and effectiveness?
