Biochemical Effects of Toxic Chemicals on Plants,human,animal,soil,and water

Biochemical Effects of Toxic Chemicals on Plants :

 Toxic chemicals have a profound effect on trees - plants.  Since the beginning, human beings have been taking many measures to increase the yield of food items, to keep food grains safe in stores, to protect the crop from animals, but these old measures have not been as useful as the toxic chemical substances. 
biochemical effect

 (1) The increasing effect of SO2 in the atmosphere is particularly harmful to plants.  It is especially fatal for apple, cotton, mango, grapes, juicy fruit leaves, flowers, and fruits.

 (2) The immediate impact has been observed on the productivity of groves and flora of urban areas in case of very small pollutants found in the soil and polluted rainfall.  The reason for this is that these pollutants react with the nutrients of the soil either in an inaccessible state or destroy them.


(3) There is a possibility of occasional fire in the forests by pollutants.

 (4) A mixture of H2S and SO2 causes special damage to juicy and seasonal crops.


 (5) Due to the excessive amounts of NO2, the growth of trees and plants is suspended and the excessive amounts can destroy them.


(6) Gases like CO2, SO2, etc. have a bearing on fruitful trees near industrial cities, especially moss.  Therefore, moss is also considered an indicator of pollution.  In the clean environment, the growth of moss on the land is completed in 7 - 8 months while its growth in the polluted environment is reduced quickly.

 (7) In the event of a lack of moisture in the soil, plants are destroyed by burning due to the over-use of agricultural chemicals.


(8) Due to excess of nitrate and phosphate elements in the aquatic system of ponds, lakes, weeds begin to grow and grow rapidly resulting in a clean water pond or lake converted into shallow, weed polluted water resources.

 Biochemical Effect of Toxic Chemicals on Animals and Human 

Many types of minerals, organic or inorganic substances and gases in water are polluted due to the dissolution of more than a certain proportion or dissolution of many unnecessary and harmful substances. 

 Many types of diseases of animals and animals arise due to the use of polluted water.  There are many types of substances in water pollutants.  


There may be bacteria, viruses, herbicides, insecticides, fungicides, chemical fertilizers, organic materials, waste materials obtained from industrial institutions, sewage, and many other substances.  

Toxins have the following biochemical effects on organisms and humans.

 (1) Many types of toxic chemicals affect the respiratory tract in many ways, as a result, many types of respiratory diseases occur. 
 Other body parts;  For example, lungs, kidneys, pulse system, etc. are also affected.  Animals may also die slowly due to excessive pollution.

 (
2) Organic or inorganic compounds of lead, mercury, etc., which are often obtained by industrial institutions, reach humans and animals through flora and fauna of reservoirs, rivers, and the sea, which has a bad effect on eyes and brain.


(3) Disinfectants, fungicides, herbicides, and chemical fertilizers used in agriculture and other works greatly affect the aquatic flora, which provides about 70% oxygen for respiration.

 (4) Oil falling on the earth by various means, oil transported by oil carriers, many types of evaporating substances such as petrol, tetrachlorethylene, which are liquefied by the atmosphere and come into the water, pollute the water.  


Oil spreads to the surface of water and damages organisms. Fish or other types of aquatic animals die in large numbers due to a lack of oxygen.  Different types of hydrogen get collected in animals and cause diseases in them.


 (5) Many types of radioactive materials produced by nuclear explosions, etc.;  Such as C14 Sn90 Ca37 and I131, etc. reach the water stream and pollute it, causing many diseases like cancer, leukemia, disability, etc.

 (6) Water polluted by feces and urine is responsible for various diseases in organisms.  Among these diseases, jaundice, typhoid, Kalra, diarrhea, phlegm, anthrax, etc. are prominent.


(7) Sulfur dioxide, isocyanide, nitrogen dioxide, carbon mono-oxide, various types of hydrocarbons, gaseous smoke, are most lethally affecting the eyes, lungs, and respiratory system.

Biochemical Effect of Toxic Chemicals on Soil 

Soil is a very important medium for all plants because, in this medium, plants grow and thrive.  The entire existence of trees and plants is based on soil.  Not only trees, animals - animals are also directly or indirectly based on soil. 

 Therefore, it is necessary that the soil is protected from pollution so that the crisis of living beings can be avoided.  Chemicals have the following effect on soil pollution.



Biochemical Effect

(1) Whatever chemicals are there to get more production under intense sage, they are toxic and harmful to beneficial organisms living in the soil.  Due to their death, the beneficial dissolution activities in the soil, nitrogen fixation activities stop.

 (2) The fertility and production of the land are gradually lost by using more fertilizers than necessary because the physical properties of the soil are badly affected by these chemicals.


 (3) Agricultural chemicals are converted into various chemical compounds when they are used in the soil system. 

 Under the soil, these chemicals undergo optical, chemical, and biological disintegration.  Due to being volatile and hydrological, these dissolved chemicals go into the atmosphere and water source.


 (4) Solid and aquatic effluents that come out of various types of factories - factories, factories, mills, public institutions have special types of toxic chemicals that are immersed in untreated soil, both for soil and crops.  

The properties of the soil are destroyed by it becoming deadly.

(5)  By mining and purification of radioactive minerals, by laboratories and power stations, by fertilizers (Benedum and Thorium), by nuclear tests, many types of radioactive elements reach the soil system, so that all of the soil, flora, and fauna are affected.

Biochemical Effect of Toxic Chemicals on Water 

Today, along with the lack of water, the problem of water pollution has arisen in cities and villages of almost all countries. 
 Today all water sources are in such a condition that their water has not been made drinkable.  
The water sources available in most of the villages are used to fulfill every requirement of human beings.


Biochemical Effect


(1) Water-soluble substances from the physical, chemical, and biological decomposition of many types of agricultural chemicals in the soil reach water sources and pollute them, thereby changing the physical and chemical properties of water forever.

 (2) Through many nuclear tests, by nuclear reactors, by chemical fertilizers, radioactive materials emitted by laboratories directly or through the soil and atmosphere are mixed in various water sources and cause radioactive pollution.


(3) The dead bodies of animals, birds, animals, humans, when they are directly carried in water, rotting and decomposing with the action of microorganisms, produce many toxic and unwanted chemicals. 
 Many acidic and alkaline nature chemicals are found in them.

 (4) Sewage discarded by humans, animals, birds, and other animals in water sources - through the flow of urine or sewage water released from toilets into water sources, or openly discharged sewage on soil which flows with water  Reaches sources, pollutes water by rotting or decomposing and decomposing.


  There are many types of compounds and deodorant gases in it, which changes the color, smell, taste of water, microorganisms are present in it.


(5) The source of chemical substances in water is actually soil and atmosphere, in which soil is more effective.  Several types of agrochemicals or contaminated soil chemicals or harmful bacteria or toxic compounds of the soil get into the water sources along with the running water of rain.

  The water sources present near the canals or saline soils passing through the saline soil are polluted by a variety of salts.  Saline wells, canals, ponds, and ponds are examples of these.


(6) Due to the nutrition of nitrate and phosphorus in water, aquatic plants grow at a rapid pace and the water sources are gradually depleted.

 (7) Many aquatic pollution-prone water sources include aquatic animals such as fishes, aquatic birds.
