For the first time that day, Micah Hayes showed his teeth, creating a wide, tooth-brandishing display, enough to freeze anything but the uppermost animals in the food chain in their tracks.
They stay inside the tissues of living creatures, often bioaccumulating, which means they lodge in fat cells and get passed up the food chain at ever-increasing concentrations.
And the ratio of carbon-12 to carbon-14 can be used to calculate the time that has elapsed since the death of the creature cut it off from the food chain and its interchange with the atmosphere.
Biomagnification of the concentration of such chemicals in the food chain was found to be dangerous to human health.
Nonorganic poultry and meats are packed with hormones and antibiotics, not to mention often full of PCBs, mercury, and other chemicals that accumulate up the food chain in the cows, pigs, lambs, and chickens we consume.
Birds of prey are especially susceptible to DDT poisoning, since it accumulates at the top of the food chain and reduces the hatchability of eggs.
While a few well-known organochlorine insecticides that are notoriously injurious to animals—DDT, for example—have been banned in the United States, even these persist for decades in the soil in which our fruits and vegetables are grown and in our water, meanwhile accumulating up the food chain which is why traces of DDT can be found in the steaks Becky has yet to cook for dinner.
