Toxic Gases and Human Life
There are many gases produced by cars, machines, and waste that can affect the flow of the oxygen within human red blood cells.
Pick from my ordinary level there are cell that transport oxygenated and de-oxygenate blood within human body.
Today in this article I shall be talking about carbon monoxide, carbon dioxide and carcinogens and the extent to which they affect both the environment and human beings. Humans local, regional and global have been encouraged to maintain a clean environment.
Carbon is a building block of molecules which make up living cells and its essential elements for life on earth. Carbon can be found in gas, liquid, fossil fuels or in solid form and moves in the atmosphere, ocean, rivers, and landmass through chemical processes and geophysical means.
It moves through the atmosphere as carbon dioxide, carbon acids and then flows to the ocean and all these gases are harmful to human beings as they may lead to air bone diseases like turbacolosis (TB), asthma and many others.
Carbon dioxide is a gas that occurs naturally in the air and is produced when animals breathe, vegetation rots and when material containing carbon is burnt or broken down. Carborn dioxide is key component in photosynthesis, a major based source of food for organisms on earth.
Through photosynthesis carbon dioxide combines with water and sunlight energy to produce sugars which provide energy for plants to grow.
Many years ago, earth atmosphere consisted on carbon dioxide until plants removed gases by way of decomposition. Human kinds have reversed the process by reversing carbon through burning fossil fuels.
Carbon dioxide is currently termed “green house gases” and absorbs heat in the atmosphere. Carbon dioxide is absorbed back into the system physically through plants, which can be tamed if humankinds destroys many trees and reduces he absorption capacity. People especially in urban centres cut down trees for fire wood sources due to erratic electricity supply.
The newly resettled farmers in Zimbabwe disturbs carbon dioxide by unnecessary veld fires that end up destroying grass and trees in search for wild animals.
Carbon monoxide is a colourless gas produced by incomplete combustion from vehicles and cigarettes. It is a toxic which combines with haemoglobin (the red blood cells) to form pink carboxy-haemoglobin, which prevents the red blood cells from transporting oxygen to the body tissues. In Most developing countries like Zimbabwe many vehicles are not road worth and produces exhaust fumes that produce carbon monoxide.
Chain smokers have a level between 9-10% and at this level nothing much can be noticed as harm except people with heart or lungs complaints. Human being should avoid smoking, burning bushes and driving un road worth cars to curb carbon monoxide
Carcinogens is a substance that can cause cancer in animal tissues as well as human beings. Carcinogens substances such as arsenic, beryllium, cadmium, cobalt, chromium and asbestos are among the substances that form carcinogens. Carcinogens can be eliminated from work place, by encouraging workers to wear protective clothing.
In Zimbabwe most gas filling tanks are not well take care of, teachers who are still using chalk boards directly breathes the chalk dust and those in industry that manufacture cement, quarry stones, builders and many other professionals should avoid carcinogens in their everyday livelihoods.
