Assalamualaikum..(Peace be upon you)
I hope you all are fine and safe.because of little business I am less active here. But try to continue writing my articles through the business. So today i'am gonna write about some chemicals which has impact on our health and environment. So let's start.
There are different types of acids, strong alkalis, salts of various metals harmful to health, various organic solvents are used in chemical laboratories. Excessive use of them in the laboratory results in them spreading to the environment in some way and entering plants and animals. Its harmful effects are long term. There is a need to be aware of their excessive use in the laboratory.When heavy metal ions Pb2 +, Hg2 +, Cd2 + enter the body, the function of enzymes in the body is lost and poisoning occurs in the body. In various heavy industrial factories such as leather industry, dyeing industry, paper, rayon, fertilizer, etc., the use of harmful substances on the environment is used. It is impossible to imagine how harmful the excessive use of these chemicals is to the environment.The use of these chemicals should be kept to a minimum and under control. Therefore, prior permission from the Department of Environment is required before setting up these factories.
Let's know about the chemical's effect one by one
Hydrochloric acid (HCl)
Health response: HCI is as deadly as gas and corrosive as acid. Causes inflammation in the mouth, throat, trachea. Taking too much as HCI can lead to death.
Response to the environment: HCI acid is a potent acid. It is fully ionized in water and rapidly reduces the pH value of water. This causes severe damage to aquatic plant and animal ecosystems
Sulfuric acid (H2SO4)
Health Response:As it is a deadly corrosive, highly corrosive and intensely dehydrating, it causes infections in the eyes, mouth, respiratory tract and inflammation of the skin. Even the lungs are affected.
Response to the environment:When it is mixed with water, the pH quality of water decreases rapidly. Disruption of aquatic ecosystems. Mixing with the soil reduces the pH of the soil. Proliferates soil microorganisms. As a result, plants can no longer grow in that soil.
Nitric Acid (HNO3)
Health response:NO2 gas in HNO3 causes severe respiratory distress due to severe corrosion and severe oxidation, skin inflammation, eye-mouth irritation; It can even lead to death.
Response to the environment :It mixes with water to reduce the pH quality of the water. Fishing and breeding of fish and other aquatic animals is disrupted. As it is corrosive, it mixes with the soil and destroys the mineral content of the soil.
Baking powder (NaOH)
Health Response:A corrosive chemical element. Only 10% W / V) Aqueous solution of baking Soda can blind the eyes in 30 seconds. If it enters the mouth in any way, it causes serious infection in the throat, trachea and stomach.
Response to the environment :It mixes with water and causes water pollution.
Ammonium hydroxide (NH4OH)
Health response:Intense pungent odor gas enters with the breath. Severe respiratory distress, sore throat and trachea. The eye burns and within moments the eyes turn purple.
Response to the environment :It dissolves in water and causes adverse reactions. Other aquatic animals, including fish, die within moments. Animals also die if they drink water dissolved in ammonia. When NH 3 is released into the air as a gas, plants burn, birds die, people suffer from shortness of breath, and even death.
Sodium bi-carbonate (NaHCO3)
Health response:when it enters the body with shortness of breath, the airways become infected. Wounds are caused by falling on the skin or eyes.
Response to the environment :It increases the pH quality of water by mixing with water. Destroys microorganisms in the soil (interferes with the decomposition of soil minerals).
Chloroform (CHCl3)
Health response: It causes severe damage to the central nervous system of animals. Severe damage to the airways and lungs in the case of respiratory infections. Death is inevitable if too much enters the lungs.
Response to the environment :It dissolves in water and destroys the micro-organisms present in the water resulting in DO. The balance of BOD and COD is lost.Here, DO means Dissolve Oxygen, BOD means Biological Oxygen Demand and COD means Chemical Oxygen demand in the water.
Soap and detergent
Health and environmental response:Both compounds are organic contaminants. Excessive use damages the skin of the body. They can not be thrown directly into the environment. They cause serious environmental disasters.

So we should use chamicals very carefully. Some chemical are less effective but it you should be careful of all chemicals. Make a well managed life with the help of chemistry and please don’t' abuse the Knowledge of chemistry.
