Biological pollutants are one of the main reasons for environmental pollution. They move in the air or hide under the objects’ faces. Various factors produce biological pollutants. Their harms to the health are significant if you don’t have suitable treating methods. 

These pollutants contribute to the development of biological pollution. It reduces the air quality and causes dangerous diseases for humans and animals.  

This article will help you learn about the biological pollutants to avoid their bad impacts.  

Scroll down for more details and read them carefully!

Definition Of Biological Pollutants

What are biological contaminants? They are living organisms. They can grow and reproduce, such as plants, protists, animals, bacteria, or fungi. They exist in the air, water, soil, dust mites, pollen, animal dander, or spoiled food. 

Biological pollutants are the main factor in biological contamination. What is a biological contamination? It is a harmful process that occurs in the food, water, and environment by microorganisms. 

The bacteria, viruses, parasites, or fungi develop inside the food, animals, or environment. They cause dangerous effects. Biological contaminants are present everywhere in different forms.   

What are biological contaminants

What is the best example of biological contamination? It is clear when a restaurant staff coughs into food for the customer. This can spread infectious viruses through the air and cause biological contamination. 

Sources Of Biological Pollutants

According to the biological contaminants definition, various sources produce biological pollutants. They are natural factors or living agents. 

The bacteria and viruses, which is a biological contaminant? Both of them are major components of biological contaminants. The viruses are alive in the human or animal body. The bacteria exist in the plant debris, soil, human, and animals.  

Besides, pollen and mold are the main sources of biological contaminants. Most of them come from natural plant species in many places.  If you inhale them, they pose health risks such as allergy, cough, or itchiness.  

The biological pollutants also originate from the household pets’ dander or saliva. 

Classification Of Biological Pollutants

The biological pollutants include different types depending on their position and sources. They have various effects. Which of the following is considered a biological human health hazard? 

The first type is water biological contaminants. It occurs when water includes decomposed organic substances or pathogenic microorganisms. These pollutants often exist in domestic, industrial, or agricultural wastewater. 

Biological air pollutants are the second type present everywhere, indoor or outdoor. The viruses and bacteria from animals or humans can transfer to other people or animals. Poor ventilation or high humidity contribute to the growth of these biological pollutants.  

Domestic sewage, rubbish, or breeding by-products in the soil produce harmful living microorganisms. They can multiply in big quantities and pollute the soil resource. This type is soil biological pollutants. 

Biological contaminants can affect food safety and quality. They alter food’s ingredients, flavors, or textures  that affect our health.

Health Effects Of Biological Pollutants

Allergic Symptom

What is one possible effect in humans of microbiological pollution? It is an allergic symptom. The indoor allergens include dust mites, house pets, insects, or living agents. They travel through many places and distribute biological pollution. 

When you inhale or contact them, you can face a lot of allergic signs. Apart from indoor allergens, pollen or mold is a natural biological pollutant.  They can result in your allergic issue. Some symptoms such as itchiness, itch, sneezing, or cough show the allergy.  

The biological pollutant allergy is relevant to dangerous diseases.  They are rhinitis, tracheitis, asthma, conjunctivitis.  

What is one possible effect in humans of microbiological pollution


Asthma is one of the popular health problems that are from biological pollutants. This disease attacks the lungs and causes breathless conditions. It is common to most people of different ages. 

The biological pollutants have a wide presence in the air. They enter your lungs to trigger asthma. They comprise the outdoor allergens and indoor factors. The outdoor allergen is pollen. Household pets, bacteria, or cockroaches are indoor factors.   

Wheezing, chest tightness or breathlessness is one of the most visible asthmatic symptoms. An asthma attack can take place for a long or a short time. It is recurring if you keep regular contact with the biological pollutants.     


Infectious Diseases

Infectious diseases are a serious health risk that comes from biological contaminants. Living agents have widespread coverage in the environment. They are viruses, bacteria, parasites, or fungi.  

They operate in the human or animal’s organs and cause abnormal symptoms for the health. The common signs include fatigue, cough, diarrhea, muscle pain, or fever. 

Contacting a person or animal with an infection is the easiest way to capture the disease. It can spread from person to person, animal to person, or the mother to baby through direct contact. 

Food contamination or insects will cause infectious diseases with indirect contact. Influenza, tuberculosis, measles, staphylococcus are common infectious diseases.     

Poisonous Symptom

The food’s biological contaminant is the main cause of the poisonous symptom. The living organisms or toxic substances penetrate the food and multiply. They destroy the food’s texture and change its taste and ingredients. 

When the food gets spoiled, it is not safe anymore. The microbial contamination results in the poisonous food symptom when eating them.  

Microorganisms are the main factors of food-borne diseases. They include viruses, bacteria, parasites, and protozoa. The poisonous symptoms are various. The most popular are ill feelings, vomit, diarrhea, stomach pain, headache, or dizziness.  

You can catch foodborne illnesses if you preserve food in unsafe conditions. The moist, protein or starch-rich, or acidity-neutral food is a favorable environment. It contributes to the growth of biological pollutants.  

What Methods Can Prevent Biological Contamination? 

Humidity Control

The biological contaminants thrive in a humid environment. Thus, humidity control is the essential solution to restrict their growth. You can control the humidity in different ways. The moisture can go through the leakages. To control it better, you should repair these seepages. 

In moist weather, air conditioners or dehumidifiers also help balance the humidity.  If you put the carpet on the house floor, pay attention to washing and drying it. This removes the harmful biological pollutants that are alive in the humid carpet. 

Clean And Monitor Indoor Environment Quality 

This method is effective in treating indoor bacterial pollution consequences. You walk through your home to make a self-inspection of the biological pollutants. Check furniture in your homes if they are in dusty or moist condition.   

You need to remove the dust or waste from your household appliances. It can prevent the growth of biological contaminants. Regular cleaning is also a simple way to avoid fungi and harmful biological factors. 

The indoor environment quality monitoring helps reduce the potential risks from biological pollutants. You can conduct an indoor air test using an air monitor or dedicated equipment. 

This test is useful to follow the indoor air quality at different times. It also helps manage and treat the biological pollutants existing in the indoor air. 

Dust Removal

Dust Removal

Dust removal is important to restrict the allergic risks from biological pollution. The dust exists on the furniture’s surface or in various places in your home or workplace. Thus, you need to clean the furniture or equipment before using it. 

Use the hot water (about 130°F) to wash your bedding every 7-10 days. You can use rubber mattress covers or rubber pillows to avoid allergic dust mites. 

Removing the dust in the objects’ surface and in your home by using a vacuum or cleaning equipment. 


The useful information above can provide you with a thorough overview of biological pollutants. They are one of the main factors that boost increasing environmental pollution and cause serious health effects. 

The diseases of allergy, asthma, or poisoning originate from biological organisms or substances. They develop under various conditions, such as water, air, soil, or food. 

Thereby, you should make some simple solutions. They include cleaning or monitoring moisture or air quality to prevent biological pollutants. This will help you protect your health and improve the living environment better.
