Plastic bags>>

What Makes Plastic Bags Harmful to the Environment?
Plastic bags are made of various chemicals which are mainly toxic. That is certainly very harmful to the health and the environment. The chemicals used to make plastic bags are xylene, ethylene oxide and benzene. These are toxic chemicals that are sources of various diseases as well as disorders in humans. They do not only provide negative effects on the health of people and animals but also to the air. These chemicals can pollute the air too which again harm the living organisms. They will not only affect humans and animals but also plants, water and air.

How Plastic Bags Cause Danger to the Health and Environment?
There are various ways on how plastic bags can harm the health of humans and the entire environment. Two major methods that release toxic chemicals of plastic bags are by burning and throwing. Whether you burn or throw plastic bags, all the chemicals are released which can cause harm to the society.

Why is asbestos dangerous?

Asbestos still kills around 5000 workers each year, this is more than the number of people killed on the road.
Around 20 tradesman die each week as a result of past exposure
However, asbestos is not just a problem of the past. It can be present today in any building built or refurbished before the year 2000.
When materials that contain asbestos are disturbed or damaged, fibres are released into the air. When these fibres are inhaled they can cause serious diseases. These diseases will not affect you immediately; they often take a long time to develop, but once diagnosed, it is often too late to do anything. This is why it is important that you protect yourself now.

Asbestos can cause the following fatal and serious diseases:
1- Mesothelioma
2- Asbestos-related lung cancer
3- Asbestosis
4- Pleural thickening

Hydrogen Sulfide (H2S)

Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten egg” smell. It occurs naturally in crude petroleum and natural gas, and can be produced by the breakdown of organic matter and human/ animal wastes (e.g., sewage). It is heavier than air and can collect in low-lying and enclosed, poorly ventilated areas such as basements, manholes, sewer lines and underground telephone/electrical vaults.

Health Effects:

Health effects vary with how long, and at what level, you are exposed. Asthmatics may be at greater risk.

Low concentrations – irritation of eyes, nose, throat, or respiratory system; effects can be delayed.

Moderate concentrations – more severe eye and respiratory effects, headache, dizziness, nausea, coughing, vomiting and difficulty breathing.

High concentrations – shock, convulsions, unable to breathe, coma, death; effects can be extremely rapid (within a few breaths).

Why is heat a hazard to workers?

When a person works in a hot environment, the body must get rid of excess heat to maintain a stable internal temperature. It does this mainly through circulating blood to the skin and through sweating.

When the air temperature is close to or warmer than normal body temperature, cooling of the body becomes more difficult. Blood circulated to the skin cannot lose its heat. Sweating then becomes the main way the body cools off. But sweating is effective only if the humidity level is low enough to allow evaporation, and if the fluids and salts that are lost are adequately replaced.

If the body cannot get rid of excess heat, it will store it. When this happens, the body's core temperature rises and the heart rate increases. As the body continues to store heat, the person begins to lose concentration and has difficulty focusing on a task, may become irritable or sick, and often loses the desire to drink. The next stage is most often fainting and even death if the person is not cooled down.

Excessive exposure to heat can cause a range of heat-related illnesses, from heat rash and heat cramps to heat exhaustion and heat stroke. Heat stroke can result in death and requires immediate medical attention.

Exposure to heat can also increase the risk of injuries because of sweaty palms, fogged-up safety glasses, dizziness, and burns from hot surfaces or steam.

Chemical Hazards at workplace:

Harmful chemical compounds in the form of solids, liquids, gases, mists, dusts, fumes, and vapors exert toxic effects by inhalation (breathing), absorption (through direct contact with the skin), or ingestion (eating or drinking).

Airborne chemical hazards exist as concentrations of mists, vapors, gases, fumes, or solids. Some are toxic through inhalation and some of them irritate the skin on contact; some can be toxic by absorption through the skin or through ingestion, and some are corrosive to living tissue.

The degree of worker risk from exposure to any given substance depends on the nature and potency of the toxic effects and the magnitude and duration of exposure. Information on the risk to workers from chemical hazards can be obtained from the Material Safety Data Sheet (MSDS) be supplied by the manufacturer or importer to the purchaser of all hazardous materials.

The MSDS is a summary of the important health, safety, and toxicological information on the chemical or the mixture’s ingredients. Other provisions of the Hazard Communication Standard require that all containers of hazardous substances in the workplace have appropriate warning and identification labels.

أسماء بعض التحاليل الطبية:

(Complete Blood Count ) (C.B.C ) وترجمته تعني "عد الدم الكامل"..يعيجنا صوره كاملة للدم ومكوناته ...

يعني هذا التحليل يشمل قياس مكونات الدم الل تشمل : R.B.C أو Erythrocytes وتعني كرات الدم الخمراء

W.B.C أو Leukocytes وتعني كرات الدم البيضاء

Platelets وتعني الصفائح الدموية

Hgb أو Hb وتعني الهيموجلوبين

وهناك مصطلخات أخرى لكن هذه من الأهم والأبرز ..

هذه التحاليل نستفيد منها في معرفة حال دم المريض من فقر الدم..نزيف..عدوى او حساسية..حسب ارتفاع كل مكون من مكونات الدم او انخفاضه .. يستخدم كتشخيص مبدأي للطبيب وعلى أساسه يطلب الطبيب تحاليل أخري حتى يشخص بشكل صحيح..
