Sodium Azide Essay

Contaminated soil, air and water are agents for toxins and infections acquisition in exposed populations. Inappropriate disposal of hazardous (some chemicals) substances also affects the environment thus human beings. Chemicals are everywhere in the environment such as home, work, hospitals, even in food. Chemicals that are considered safe can become harmful if misused; for example, pesticides, detergents, ammonia and drugs. Unfortunately, some nuclear substances and chemicals used in healthcare also contribute in human health degradation.

Poor air quality and breathing in the dry residues from toxigenic organisms can cause multiple health concerns. This material has the potential to create havoc in many ways.

Personal Protection-Readily absorbed through skin. Very destructive of mucous membranes and upper respiratory tract, eyes and skin. Severe irritant. Sublimes at room temperature to yield dangerous levels of vapour. May cause sensitization. May cause damage to the unborn child.

For this lab, we must be sure to always wear our safety glasses whenever we are in the laboratory and wear gloves when we are conducting an experiment. Benzoic acid and sodium benzoate used in this experiment can be mild irritants to the skin. We must be careful not to get them on our skin or

Hazardous materials are defined by OSHA as “any substance to which exposure results or may result in adverse affects on health or safety”. It’s important to be able to identify hazardous material as emergency response personnel in order to properly handle any situation that arises. There are over 2,000+ hazardous materials, all separated into 9 classes, this system has been put in place to help responders formulate a plan of action. Focusing on class 2 hazardous gasses, their history, and uses.

Thiazides are diuretic that works on removing extracellular fluid from the body. It is used in heart failure and hypertensive patients. Thiazide diuretic works primarily in the distal tubular of the kidneys. Diuretics affects the electrolyte balance and reduce blood pressure in the body and therefore should be monitored closely. Thiazide diuretic works by decreasing plasma volume which reduces venous return and diminishes cardiac output causing blood pressure to fall. This change in plasma volume with a diuretic can stimulate both the sympathetic nervous system and the renin-angiotensin-aldosterone system. The degree in which these systems activate governs the magnitude of acute blood pressure decrease with both diuretic monotherapy and diuretics given in combination with

We must make sure to not mix sodium hypochlorite with ammonia because it produces toxic vapors. Inhalation of sodium hypochlorite can irritate the lungs, so if this happens seek fresh air immediately and call for medical help if needed. While low concentrations prevent skin damage, high concentrations on our skin can cause burns and irritation. Sodium hypochlorite is also an eye irritant. If skin and eyes come into contact with sodium hypochlorite, flush with water immediately and seek medical attention if this doesn’t

There are many types of chemical agents that can be used for a variety of effects. Most are not meant to be lethal, but most chemicals at high concentrations can be lethal.

Sodium hydroxide can cause skin, respiratory and eye irritation at 1 mol 〖dm〗^(-3)but at 8mol 〖dm〗^(-3) it is highly corrosive. When mixed with water it can produce a lot of heat, which could ignite combustibles

Chloroethane or monochloroethane, commonly known by its old name ethyl chloride, is a chemical compound with chemical formula C2H5Cl, once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor. Ethyl chloride is a chemical compound with chemical formula C2H5Cl, once widely used in producing tetra-ethyl lead, a gasoline additive. It is a colourless, flammable gas or refrigerated liquid with a faintly sweet odour. Ethyl chloride is produced by the reaction of ethylene and hydrogen chloride over an aluminium chloride catalyst at temperatures ranging from 130-250°C. Under these conditions, ethyl chloride is produced according to the chemical equation:

Zinc is an essential mineral that plays roles in multiple bodily functions such as participating in the transcription of DNA, translation of RNA, having multiple roles in the perpetuation of genetic material and cell division (Christine Hotz et al. 2004). A lot of these roles, although they are only a fraction of zinc does in the body, are related to the development of a child during pregnancy. A zinc deficiency causes a decrease in growth and development of the fetus, as well as errors in timing, sequencing, and efficiency of parturition, the action of giving birth (Laura E. Caulfield et. Al 1998). These consequences can lead poor health of the mother the child and increase chances of needing and operative surgery. Since zinc is an essential nutrient, humans only obtain zinc through the absorption of

AZT is interfering with the inhibition of DNA replication because it has to do with genome replication which is reverse transcriptase as I said earlier. Human DNA is polymerases so AZT can act as substrate.

HCN is extremely toxic to humans and environment, has potential to explode. HCN can access via all exposure routes including inhalation, skin absorption, ingestion, skin and/or eye contact. Prolonged exposure to low concentrations or short-term exposure to high concentrations may result in adverse health effects. HCN becomes unstable with water, heat and alkaline materials. It reacts with calcium hydroxide, caustic substances, acids, sodium hydroxide, amines, ammonia and oxidants. It can polymerise between 50°C to 60°C in presence of moisture, heat and alkaline

The active component of film is silver nitrate halide crystals that is coated on a transparent material, such as photo paper. As the film is exposed to light, the sensitive components in Silver Nitrate cause it to darken when exposed to the light. The exposure creates a latent image, where there seems to be no visible change on the photo paper or film. As time went on and photographic film became more complex. Different compounds to make colors and faster and finer quality crystals were discovered to make sharper images were. Although with all the new discoveries photography still relied on silver salts. These salts were almost constantly prepared from silver nitrate. Silver nitrates solubility and lower sensitivity to light makes it ideal

The odor invades homes and some days mist will hit cars and homes (Wing S, 2002). As previously noted, the waste contains pathogens and antibiotic-resistant bacteria. As this spray is impacting residents’ homes it is reaching public water sources. The mist contains hydrogen sulfide and ammonia which cause irritation of the eyes and respiratory system (Wilson SM, Serre ML, 2007). Research indicates these spray fields cause mental stress, decreased quality of life, and raised blood pressure on nearby residents.
