Vinegar Eel Bio gp essay help Art homework help

The most toxic metals were silver, lead and iron, all killing the eels in under four minutes, with silver taking only 1 minute and 40 seconds to kill the eels, and only 13 seconds to make the eels stop forward motion. Strontium wasn’t effective as after 5 minutes of exposure to it, the eels hadn’t died or stopped forward motion. 2) a) The accepted toxicity varies from metal to metal. The accepted toxic level of lead is 0. 0012 parts per million, however it is not considered safe at any level.

The environmental protection agency says that the maximum contaminant level for cadmium In drinking eater is 0. 05 MGM/L. In soil it is said that the highest amount of cadmium that can be accepted in land is 85 MGM/keg. For Mercury the accepted toxic level in aquatic systems in IPPP b) Heavy metal pollution is a problem usually associated with areas of Intensive Industry. However, roadways and automobiles now are considered to be one of the largest sources of heavy metals. Zinc, copper, and lead are three of the most common heavy metals released from road travel, accounting for at least 90 of the total metals in road runoff. Lead concentrations, however, consistently have been decreasing since leaded gasoline as discontinued.

Smaller amounts of many other metals, such as nickel and cadmium, are also found in road runoff and exhaust. About half of the zinc and copper contribution to the environment from arbitration is from automobiles. Brakes release copper, while tire wear releases zinc. Motor oil also tends to accumulate metals as It comes Into contact with surrounding parts as the engine runs, so oil leaks become another pathway by which metals enter the environment. C) Yes, these heavy metals can fasciculate in organisms in our food chain, especially fish. This is because heavy metals are part of Earth’s crust; they can be worn away by the action of weather.When they are worn off of rock, they can collect In surface or groundwater.

Humans can sometimes eat these fish, which isn’t good because heavy metals such as lead, cadmium, cobalt, nickel, and mercury can affect blood cells. The build-up of heavy metals can cause harm to the liver, kidneys, the circulatory system and the movement of nerve signals. Some of these metals can also contribute to the development of different types of cancers. D) As stated above, these heavy metals can cause harm to the liver, kidneys, regulatory system, and nerve signals, as well as the formation of blood cells.Again, they can also contribute to the development of different types of cancers. E) A portion of harmful chemical pollutants can be removed by a process known as premeditation, a process involving microorganisms or plants that help clean up the pollutants. Reacting contaminants with certain chemicals can also make them less harmful.

Conclusion: they affect most organisms the same way they affected the vinegar eels. And because there aren’t very many ways to clean up the metals, we need to change our actions.
