Method 2, cleaning painted. Walls 1, remove marks or stains first. Test your product on an inconspicuous area of the wall first before cleaning the stain off, to make sure that the stain remover won't lift the paintwork. Make sure to read the directions first and apply carefully. 2, wash the walls. For most painted walls, warm, soapy water will work just fine.

You want to be able to get at dust thats built up behind dressers, appliances, and other etiquette types of furniture. You can clean these often-neglected areas now that the furniture is out of the way. 3, dust the walls. Use either a broom, a dusting brush, or a vacuum cleaner to do this. Run the broom, brush, or vacuum up and down the walls in a vertical motion. Use a ladder to get into high corners, or enlist a tall friend to help. 1, if the broom or brush has strong bristles, tie an old t-shirt or other cleaning rag over it to prevent the sharpness of the bristles from scratching against the wall. Rinse out the shirt or rag or grab a new one when it gets too dirty, since you dont want to spread the dirt from one wall to the next! 4, start at the top of the wall when washing. Then, move up gradually, drying as you go, so you dont leave behind any streaks or drip marks.

Analysis of samples of his hair revealed significant amounts of arsenic. Helena has a rather damp climate, it is likely that fungus grew on the walls.

13 Under wet conditions, the loyalty mold Scopulariopsis brevicaulis produced significant amounts of methyl arsines via methylation 14 of arsenic-containing inorganic pigments, especially paris green and Scheele's Green. In these compounds, the arsenic is for either pentavalent or trivalent (arsenic is in group 15 depending on the compound. In humans, arsenic of these valences is readily absorbed by the gastrointestinal tract, which accounts for its high toxicity. Pentavalent arsenic tends to be reduced to trivalent arsenic and trivalent arsenic tends to proceed via oxidative methylation in which the trivalent arsenic is made into mono, di and trimethylated products by methyltransferases and an s-adenosyl-methionine methyl donating cofactor. 15 16 However, newer studies indicate that trimethylarsine has a low toxicity, and could therefore not account for the death and the severe health problems observed in the 19th century. 17 18 Arsenic is not only toxic, but it also has carcinogenic effects. 16 Role in Napoleon's death edit during Napoleon's exile. Helena, he resided in a house in which the rooms were painted bright green, his favorite color. The cause of his death is generally believed to be stomach cancer, and arsenic exposure has been linked to an increased risk of gastric carcinoma.
Nineteenth-century journals contained reports of belly children wasting away in bright green rooms, of ladies in green dresses swooning and newspaper printers being overcome by arsenic vapors. There is one example of an acute poisoning of children attending a christmas party where dyed candles were burned. 10 Two main theories on the cause of wallpaper poisoning events have been proposed: dust particles caused by pigment and paper flaking, and toxic gas production. Tiny particles of the pigment can flake off and become airborne, and then are absorbed by the lungs. Alternatively, toxic gas can be released from compounds containing arsenic following certain chemical processes, such as heating, or metabolism by an organism. When the wallpaper becomes damp and moldy, the pigment may be metabolised, causing the release of poisonous arsine gas (AsH 3). Fungi genera such as Scopulariopsis or paecilomyces release arsine gas, when they are growing on a substance containing arsenic. 11 12 The Italian physician Bartolomeo gosio published in 1893 his results on "Gosio gas that was subsequently shown to contain trimethylarsine.
in the form of atmospheric hydrogen sulfide or in pigment mixtures based on or containing sulfur. Emerald green, also known as Paris Green, was developed later in an attempt to improve scheele's Green. It had the same tendency to blacken, but was more durable. By the end of the 19th century, both greens were made obsolete by cobalt green, also known as zinc green, which is far less toxic. Scheele's Green was used as an insecticide in the 1930s, together with Paris Green. 5 6 7 Despite evidence of its high toxicity, scheele's Green was also used as a food dye for sweets such as green blancmange, 8 a fondness of traders in 19th-century Greenock ; this led to a long-standing Scottish prejudice against green sweets. 9 Toxicity edit In the 19th century, the toxicity of arsenic compounds was not readily known.
Added to a copper sulfate solution, it produced a green precipitate of effectively insoluble plan copper arsenite. After filtration the product was dried at about. To enhance the color, the salt was subsequently heated to 6070. The intensity of the color depends on the copper : arsenic ratio, which in turn was affected by the ratio of the starting materials, as well as the temperature. It has been found that Scheele's green was composed of a variety of different compounds, including copper metaarsenite (cuoas 2O 3 copper arsenite salt (cuhasO 3 and Cu(AsO 3) 23H 2O neutral copper orthoarsenite (3cuoas 2O 32H 2O copper arsenate (CuAsO 2 and Cu(AsO 2). 3 Scheele's Green was used as a color for paper,. For wallpapers and paper hangings, and in paints, wax candles, and even on some children's toys.

Not to be confused with copper arsenate. Scheele's, green, also called, schloss, green, is chemically a cupric hydrogen arsenite teresa (also called copper arsenite or acidic copper arsenite cuhasO. It is chemically related. It is a yellowish- green pigment which in the past was used in some paints, but has since fallen out of use because of its toxicity and the instability of its color in the presence of sulfides and various chemical pollutants. Scheele's, green was invented in 1775 by, carl Wilhelm Scheele. By the end of the 19th century, it had virtually replaced the older green pigments based on copper carbonate. Contents, preparation edit, the pigment was originally prepared by making a solution of sodium carbonate at a temperature of around 90 C, then slowly adding arsenious oxide, while constantly stirring until everything had dissolved. This produced a sodium arsenite solution.
