Mercury can accumulate in the body over time, making diseases and disorders potentially linked to one’s exposure, difficult to diagnose. High mercury levels can damage major organs as well as the immune system. The main adverse effect of the inorganic mercury contained in skin lightening soaps and creams is kidney damage.9 Mercury in skin lightening products may also cause skin rashes, skin discoloration and scarring, as well as a reduction in the skin’s resistance to bacterial and fungal infections.1,3 Other effects include anxiety, depression or psychosis and peripheral neuropathy.1–3
1% hydrocortisone cream is a local steroid that can inhibit mild disease, and tar-containing preparations are effective in treating plaque psoriasis. Scalp psoriasis Scalp psoriasis is a common
Chemical properties Pyridine is miscible with water and virtually all organic solvents. It is weakly basic, and with hydrochloric acid it forms a crystalline hydrochloride salt that melts at 145–147 ° C. Most chemical properties of pyridine are typical of aheteroaromatic compound Molecular properties Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. In contrast to benzene, the electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom.
1.Chemical properties Elemental mercury (Hg) has an atomic weight of 200.59 u, oxidation states 0, +1 and +2. Is a liquid and volatile metal soluble in water to some extents? In the oxidation states +1 and +2 is able to form organic compounds of type RHgX and R2Hg where R can be alkyl- or Aryl groups. The RHgX compounds properties depend on the nature of the X rest; If the organic compound contents hologenides the result is a highly lipophilic compound whereas If the rest is oxygen anion, chemically stable, thermally labile and light sensitive compounds are formed. Nevertheless, away from the properties differences, both kind of compounds are crystalline.
The principle involved in this test is the precipitation of phosphate which bores a yellow-colored solution and yellow precipitate. In the sample, neither a yellow-colored solution nor a yellow precipitate appeared which indicates the absence of phosphate in the sample. In the test for Purines, or Murexide test, the standard solution used was solid guanine. The reagents used were concentrated HNO3 and 10% KOH.
*Antiseptic and disinfectant in insecticides, preservatives, and batteries. *Antibacterial. * Obsolete substance. Preparation: Mercuric chloride can be obtained by the addition of hydrochloric acid to a hot, to concentrated solution of mercury (I) nitrate: HgNO3 + 2 HCl → HgCl2 + H2O + NO2 Mercury is one of the few liquid elements.
Yashmakova, Alexandra 9/3 21 February, 2016 RESEARCH PARAGRAPHS ALUMINUM OXIDE Aluminum oxide is a chemical compound with the chemical formula Al2O3 which consists of oxygen and aluminium. It is found in the nature as the mineral corundum which is colourless and very hard substance used as an abrasive. Aluminum oxide is characterised with its colour, insolubility in water and its melting point which is 2030 oC. The boiling point of this compound is 2977oC. Its density is 3.97 g/cm³.
Escherichia Coli aka E. Coli, has the ability to absorb and contain uranium. Although there are strains of it that can cause disease, this can handle nuclear waste. While it would be good if this bacteria did disappear, nuclear waste spills could get out of hand. For example, if a spill had gone into the ocean, this could potentially get into our water supply and harm marine animals. By harming the marine animals, they could eventually mutate or become harmful to us when consumed.
Medical Marijuana Medical Marijuana is a marijuana plant used to treat health problems. Medical Marijuana can be beneficial but controversial. Medical marijuana serves as a medicine to treat health problems, it has many side effects short and long term, and there are different ways to take marijuana. A chemical called Cannabinoids are put in some pills to help with treating health problems.
Deeper approach of natural science such as biomedicine is important related to marine contamination. Biomedicine knowledge particularly in anatomical, physiological, genetic and biochemical models are proven to be very useful to explain the impact of contamination in life organisms in marine ecosystem. Furthermore, it can also develop explanation about what kind of disease that might be created because of the toxic compound entering the food chain (Hansen, 2007). For example is the case of Minamata in Niigata prefecture, Japan, where heavy metals produced by chemical factories pollute marine area can enter the food chain and accumulate in marine organism and even human
Ibuprofen can be brought over the counter and it can also be prescribed by a doctor. Ibuprofen is normally in tablet form. The chemical formula for Ibuprofen is C13H1802. Ibuprofen contains more hydrogen out of the three. The side effects of Ibuprofen are as followed: blistering, peeling, swelling in the hands or ankles, nausea, and sever stomach pain.
Water Pollution: Harming the Human Health The release of chemicals affects water pollution in the Chesapeake Bay, affecting the health of the human population. There are several chemicals which are more common in the Chesapeake Bay than others. A growing concern for the Bay is the amount of nitrogen and phosphorus there is since it continues to grow each year.
