Maria Call Professor Williams English 100 7 March 2013 Atrazine in Water is a Threat Dirty water is one of the world’s biggest health risks and continues to threaten quality of life. We rely on clean water to survive and key sources that we receive our water from are being tainted with a chemical called atrazine, which is an economical pesticide used on most corn, grain, sugar cane, citrus, pineapple, and sorghum to control weeds (Williams 23). Atrazine is also one of the most widely used pesticides in the world and in the United States alone, more than 80 million pounds are applied annually (Hayes et al. 1). Hayes argued, “the impacts of atrazine on amphibians and on wildlife in general are potentially devastating” (Hayes et al.
According to the Hawaii Department of Agriculture is participating in a multi agency campaign to stop the spread of the coquis in Hawaii. The reason for this is because the coqui doesn’t have a natural enemy to keep the population down, also because of the warm temperature they breathe year around. The Hawaii Agriculture department stated that “in some area’s the population of the coqui is around 10,000 frogs per acre” no wonder people in Hawaii can’t sleep It is like a law mower running all night. If someone in Hawaii is caught transporting or selling a coqui is in violation of the Hawaii state law.

It is caused by ascomycetous fungi, called Mycosphaerella musicola (2). Black Sigatoka can also be referred to as black leaf streak. Black Sigatoka could potentially be devastating to the banana species because it could yield losses of 50% or more, cause significant reductions in leaf area, premature ripening, and potentially a serious defect in fruit (3). This plant disease tends to infect banans that are used for desserts, cooking, and plantains susceptible (5). The Sigatoka disease was first found in the Sigatoka Valley in Fiji in 1963.
The production of noxious and/or toxic alkaloids from the skin glands of poison frogs has resulted in distinct ecological relationships that may prove to be an ideal example for certain complex biological interactions around the world. The distribution of poison frogs is limited to mainly the tropical habitats of Central and South America. There are over 221 species of poison frogs in the Family Dendrobatidae, in which the three genera Epipedobates, Phylobates, and Dendrobates contain the most toxic and visually brilliant species. The vertical niche range of the poison frogs occurs between ground level to about 10 feet high on trees (Darst et al. 2004).

Ricinus communis (ricin) is one of the most deadly toxins that has been discovered. It is a protein toxin extracted from the castor bean plant and a single molecule can kill an entire cell. The mechanism of action is by destroying the ribosome within a cell, which prevents protein synthesis. The toxin works as a slow poison, eventually causing a total body failure, as necessary proteins are not replaced. This common toxin can be found in gardens and wild areas around the world and is wildly grown for the oil it produces.
corinthians college inc. | Non-Native Species | Environmental Science 1001M | | Clara Negrete | 6/11/2011 | This document is based on discussing the depths of introducing invasive species in the state of California. | There are many different types of invasive species that are not native to California. Some of them are persea mites and avocado thrips that attack avocados. These are native to Mexico where the where avocados come from. Here we have some species that are native to the United States but still can be invasive if they are moved to another part of the same country.
It can be created by adding sulfuric acid and hydrogen peroxide on a variety of Copper (II) compounds. Copper (II) Sulfate has more uses in today’s society than one would think. Adding lime to copper (II) sulfate penta-hydrate it is known as Bordeaux, and kills off germs on berries such as grapes and watermelons. Pool owners add it to their chemical concoction in the summer as an algaecide. Copper (II) sulfate is toxic to fish, and must be used wisely when eradicating pesky snails and fish parasites.
