Poison ivy, oak, and sumac contain an oil called urushiol which is readily absorbed through the skin and elicits dermatitis. Poison ivy, oak, and sumac are extremely common sources of dermatitis rashes that affect people from every age group; although, sensitivity can decrease with age. The reason for this is its ability to elicit an allergic reaction in the skin which is caused by the oily resin urushiol. Armstrong and Epstein state that it only takes 50 micrograms of urushiol to cause a reaction in most people. This is about the same amount as a grain of salt. Identifying Poison Ivy Poison ivy (Toxicodendron radicans) contains clusters of three distinct leaflets with the middle leaflet slightly longer than the other two. Typically these leaflets are 2-4 inches long. The leaflets are not connected at the same point on the plant but alternate at their connection point. Poison ivy usually forms as a vine but can also be found as a bush. In the spring the leaflets obtain a red coloration, turning to shiny green, and then yellow, red, or orange in the fall. Small green flowers grow in bunches at the stem near the leaflets. White drupes (drupes having only one seed while berries have …show more content…
Contrary to popular thought it is not actually secreted by the plant. This means that casual contact will not cause an allergic reaction unless the plant is damaged and the urushiol is exposed. Even small breakages of the plant can expose the urushiol contained within, so even though it doesn’t look crushed there may be an exposure hazard.Urushiol samples aged over 100 years have been known to elicit an allergic response and can easily penetrate the skin. Scratching and rubbing an area containing urushiol spreads the oil and expands the contamination. A simple test to determine if a plant contains urushiol is to crush a leaf between a sheet of white paper. The urushiol in the plant will darken due to oxidation after 10
Anacostia is a historic neighborhood in Washington DC, located east of the Anacostia River. First appearing on the oldest map of Capitan John Smith, Anacostia was once home to a Native American tribe called Nacotchtank. These natives often referred to themselves as Anaquashtanks, which means trading village in their native language, Algonquian. Anacostia once served as a prime located as a trading port for natives and settlers in the 1600’s.

The White Snakeroot is a plant that is very commonly found across the southern regions of the United States and was initially believed to be harmless. It was believed to be harmless because its appearance is very non threatening. It is a very beautiful plant with medium sized white flowers and a green stem. It wasn’t until after it had killed hundreds of people and livestock that we realized that it produced toxic chemicals, that if consumed, was cause certain death. The explanation of this plants deadly nature contributes to the author’s thesis.
The seeds themselves were not poisonous, but the mold that grew on them, was quite poisonous. The mold is a fungus named Rhizoctonia leguminicola. Rhizoctonia leguminicola produces a potent alkaloid known as swainsonine, a compound well known to ranchers and veterinarians as a killer of livestock (Krakauer 193-194). The mold theory was disproved by University of Alaska chemists Edward Treadwell and Thomas Clausen in 2007 (205). Clausen and Treadwell concluded that the amino acid L-canavanine caused his death.

They reproduce rapidly with its seeds which need pollinating. Within 24 hours after pollination, flower parts wither and ovaries swell up and 3 weeks later the seeds finally develop into Samaras. The Silver Maple species is an angiosperm as the leaves change colors with the seasons and also because the mature seed is surrounded by an
In chapter 6 titled “Carbon Monoxide (CO), Part 1” of The Poisoner’s Handbook by Deborah Blum the most interesting story developed within the chapter was the death of Anna Fredericksen after inhaling carbon monoxide. It was interesting because the way the murder was convicted, it created the impression as if Francesco Trivia had cut her into pieces, making him look like a lunatic killer. As Gettler noted in his inquiry, “In each glass vessel, each ceramic dish, the bloody solutions, instead of turning the darkish grays of normal oxygenated blood, flamed that brilliant red. Her blood was saturated with carboxyhemoglobin.” (Blum 148).
The Kudzu vine is an extremely belligerent and invasive plant that can grow out of control once established. Kudzu overtakes and covers all plants in its path which results in the elimination of native plant species. It can cover trees and block out the light needed for the photosynthesis process or damage the limbs of the tree with the intense weight of the vines. It also has the capability to leave land worthless for agriculture or forestry. This amazing and terrifying vine covers the South and is spreading throughout the country at an incredible rate.
White blotches on basement walls can be a problem in and of themselves but can also indicate a deeper problem: basement moisture. Basement moisture is not something that can be "lived with. " It is not enough to dry it up when you see it because the long-term consequences are mold damage and possibly foundation damage. The white blotches themselves are either white mold or basement efflorescence. Either could indicate a need to seal basement walls.
Form Analysis of Chapter 8 of The Poisoner’s Handbook by Deborah Blum Deborah Blum is portraying the idea that things that seem safe or even beneficial can actually be very dangerous.

Elements of form used in chapter eight to support her idea include completion, choice of form, outside sources/ flashbacks, and active details. The completion of the chapter is used by Blum to support the idea that seemingly harmless things can be very dangerous.
