Biological pollution, or biopollution, refers to the introduction of exotic species, which can have adverse effects on indigenous communities and ecosystems. It can be caused by human activities such as industrialization, urbanization, and the opening of polar sea routes, or it can occur naturally through the spread of invasive species. Biological pollutants include bacteria, viruses, mold, pollen, and animal dander, which can cause allergic reactions and spread infectious diseases. These pollutants can contaminate water bodies, leading to serious health hazards, and also impact indoor air quality, particularly in damp environments. The magnitude of biopollution can be assessed using tools like BINPAS, which translates data on invasive species impacts into uniform measurement units. Understanding and addressing biological pollution are crucial for mitigating its ecological, economic, and public health consequences.

Biological pollutants include bacteria, mould, pollen, viruses, and animal dander
Biological pollution, or biopollution, refers to the invasion of an ecosystem by an alien species, and the subsequent changes to that ecosystem. The impact of biological pollution can be quantified using the Biopollution Level (BPL), which ranges from "no impact" to "strong". Biological pollutants can contaminate drinking water and the air we breathe, causing adverse effects on human health.
Mould, also known as mildew, can grow in damp conditions, often as a result of water damage. It can be challenging to completely rid a home of mould, but controlling the relative humidity between 30-50% can help to minimise its growth. Mould and mildew release disease-causing toxins and can trigger allergic reactions in individuals, including asthma.
Bacteria, such as Salmonella and Vibrio cholerae, can contaminate water sources, leading to serious health hazards if the polluted water is consumed. Viruses, including influenza, measles, and chickenpox, can be transmitted through the air and cause infectious illnesses.
Animal dander, or pet dander, is another common biological pollutant that can trigger asthma and cause allergic reactions in individuals. Good housekeeping practices, such as regular cleaning and vacuuming, can help to reduce the presence of animal dander, pollen, and other allergens in the home.

Biological pollution causes adverse economic consequences and impacts on human health
Biological pollution, or biopollution, is the impact of human activities on the quality of aquatic and terrestrial environments. It specifically refers to the introduction of invasive alien species (IAS) that are non-indigenous to the environment. These species can cause adverse effects at various levels of biological organization, from individual organisms to entire ecosystems. For instance, when introduced to an aquatic environment, biological pollution contributes to water pollution.
Biological pollution has significant economic and health consequences. Economically, biological pollution can lead to a decline in the naturalness of nature conservation areas. This can have a ripple effect on industries such as tourism and recreation that depend on the ecological integrity of these areas. The introduction of IAS can also cause genetic changes in native species, impacting the stability of local ecosystems that many economies rely on for resources and income.
The health impacts of biological pollution are equally concerning. Biological contaminants, including bacteria, viruses, fungi, and pollen, can trigger allergic reactions such as hypersensitivity pneumonitis, allergic rhinitis, and asthma. These contaminants are often found in indoor environments like residential areas, hospitals, and offices, and their effects can be aggravated by heating or inadequate ventilation. Infectious illnesses such as influenza, measles, and chickenpox can be transmitted through the air, and molds and mildews release disease-causing toxins that can lead to respiratory and digestive problems.
Additionally, biological pollution can contribute to the spread of pathogenic microorganisms in healthcare settings, affecting patients, staff, and visitors. Studies have also shown a relationship between particulate matter (PM) and adverse health effects. Fine particles with diameters of 2.5 micrometers or smaller, known as PM2.5, can be inhaled and cause serious health issues. These particles can reach the lungs and even enter the bloodstream, leading to potential cardiovascular and respiratory issues.
The impact of biological pollution on human health is not limited to physical ailments but also extends to mental health. Environmental noise, often associated with pollution, is an independent public health risk that can have significant effects on cardiovascular health. The consequences of climate change, such as food safety issues, ice and iceberg melting, and damage to plants, can also contribute to psychological distress and impact human well-being.

Indoor air quality is affected by biological pollutants, triggering allergies and infections
Biological pollutants, or contaminants, are a major cause of concern for indoor air quality. These contaminants include bacteria, moulds, mildew, viruses, animal dander, pollen, house dust, mites, cockroaches, and pest droppings. They can trigger allergies and infections, with symptoms such as sneezing, watery eyes, coughing, shortness of breath, dizziness, lethargy, fever, and digestive problems. Allergic reactions may occur after repeated exposure to a specific allergen, and people with prior mild reactions can suddenly become very sensitive.
Mould, dust mites, pet dander, and pest droppings are common triggers of asthma. Additionally, contaminated central air handling systems can become breeding grounds for mould, mildew, and other biological contaminants, which are then distributed throughout the home. Controlling relative humidity levels between 30-50% can help minimise the growth of these biological contaminants.
Some specific allergic reactions caused by biological pollutants include hypersensitivity pneumonitis, allergic rhinitis, and certain types of asthma. Infectious illnesses transmitted through the air include influenza, measles, chickenpox, tuberculosis, staphylococcus infections, Legionella, and measles.
The rise in allergic diseases has been linked to modern Westernised lifestyles, characterised by increased urbanisation, more time spent indoors, and antibiotic usage. Children, the elderly, and those with breathing problems, allergies, or lung diseases are particularly susceptible to disease-causing biological agents in indoor air.
To mitigate the impact of biological pollutants, allergic individuals should use allergen-proof mattress covers, wash bedding in hot water, and avoid furnishings that accumulate dust. Regular cleaning and disinfection of basement floor drains are also recommended, as well as operating a dehumidifier to maintain optimal humidity levels.

Water bodies are polluted by wastewater, causing serious health effects when consumed
Biological pollution refers to the contamination of ecosystems by non-native species, which can have adverse effects on the environment, economy, and human health. Water bodies are particularly susceptible to pollution from wastewater, which can have severe health consequences when consumed.
Wastewater is produced by various human activities, including agricultural, industrial, and domestic sources. Agricultural wastewater contains pesticides, fertilizers, and animal waste, which can contaminate water bodies through runoff during rainfall or irrigation. Industrial wastewater often contains toxic chemicals, which can pollute rivers, streams, and oceans if not properly treated. Domestic sewage, released into water bodies without treatment, contributes to environmental pollution and the spread of diseases.
When wastewater enters water bodies, it introduces harmful microorganisms, chemicals, and pathogens. These contaminants can breed diseases and cause health issues in both humans and animals. The consumption of polluted water can lead to the spread of diseases such as typhoid, cholera, giardia, and various other viral, bacterial, and protozoan infections. Prolonged exposure to contaminated water and the consumption of crops irrigated with wastewater can also result in skin diseases, digestive problems, and other adverse health effects.
The use of wastewater in agriculture is driven by factors such as water scarcity, economic benefits, and climate change adaptation. While it provides a consistent water source for irrigation, the presence of pollutants poses significant risks to the environment and human health. In developing regions, the use of untreated or partially treated wastewater for irrigation is common, contributing to a high burden of water-related diseases.
The impact of wastewater pollution on human health is significant, with more than 80% of diseases and 50% of child deaths worldwide associated with poor water quality. Additionally, the long-term consumption of contaminated water and crops can lead to adverse health effects, including increased medical disability and impaired physical and cognitive development.
To address the issue of water bodies being polluted by wastewater and the resulting health effects, proper wastewater treatment and disposal practices are essential. This includes treating industrial waste effectively and ensuring that sewage is treated before being released into water bodies. Additionally, promoting hygienic practices, such as washing vegetables with clean water, and providing education on the risks associated with wastewater use can help mitigate health risks for consumers.

The presence of invasive species impacts indigenous communities and ecosystems
Biological pollution, or biopollution, refers to the invasion of an ecosystem by an alien species, which causes harm to the environment, economy, or human health. The presence of invasive species has detrimental effects on indigenous communities and ecosystems.
Invasive species are often introduced to new environments accidentally or intentionally, and they can spread aggressively due to their ability to reproduce quickly. These species can be any living organism, including amphibians, plants, insects, fish, fungi, bacteria, or even seeds or eggs. They are typically considered invasive when they cause harm to their new environment, either ecologically, environmentally, or economically.
The impact of invasive species on indigenous communities and ecosystems can be both direct and indirect. Directly, they can prey on native species, outcompete them for food and resources, transmit diseases, and prevent native species' reproduction. For example, the brown tree snake (Boiga irregularis) caused the extinction of nine bird species in Guam. Additionally, the hemlock woolly adelgid (Adelges tsugae) has caused significant damage to eastern hemlock trees by feeding on their sap.
Indirectly, invasive species can alter the food web within an ecosystem. They can destroy or replace native food sources, impacting the abundance and diversity of species that native wildlife relies on. For instance, plant invasions have been shown to modify carbon and nitrogen cycles and fire regimes in invaded ecosystems. The invasion of downy brome in Western U.S. grasslands has led to more frequent and intense wildfires.
Invasive species can also change the conditions of an ecosystem, such as soil chemistry or wildfire intensity. Aggressive plant species like kudzu can rapidly replace diverse ecosystems with a monoculture of their own. Furthermore, some invasive species carry diseases that can spread to both wildlife and humans. The introduction of new diseases can have significant impacts on indigenous communities, as seen with the spread of exotic diseases like HIV to wider populations.
The presence of invasive species has substantial economic implications as well. Globally, the management and control of invasive species cost approximately $1.4 trillion annually. These costs have been increasing, quadrupling every decade since 1970. The economic impact of invasive alien species was estimated at over $423 billion annually in 2019. These financial burdens arise from the need to control the spread, mitigate impacts, and restore affected ecosystems.
