Air And Water Pollution: Monitoring For A Healthy Environment

Water and air pollution are pressing issues that can have detrimental effects on human health and the environment. Water pollution occurs when harmful substances contaminate bodies of water, degrading water quality and rendering it toxic. Air pollution, on the other hand, fills the air with harmful substances that can cause respiratory issues and other health problems. To address these concerns, individuals can take proactive steps to monitor and improve both air and water quality. This includes utilizing resources such as air quality indexes, investing in air purifiers and filters, and advocating for stronger environmental regulations to reduce pollution from agricultural, industrial, and commercial activities.

Understand air quality and health risks

Air pollution is defined as the presence of one or more contaminants in the atmosphere, including dust, fumes, gas, mist, odour, smoke or vapour, in quantities that can be harmful to human health. The main route of exposure is through the respiratory tract, but some pollutants are small enough to enter the bloodstream via the lungs and circulate throughout the body.

There are several ways to check air pollution levels. The Air Quality Index (AQI) provides real-time air pollution data for over 80 countries. The AQI measures levels of particulate matter (PM2.5 and PM10), Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2) and Carbon Monoxide (CO) emissions. These pollutants have been linked to a range of adverse health effects. Fine particulate matter, for example, can penetrate deep into the lungs, enter the bloodstream, and damage tissues and cells throughout the body. Short-term exposure to high levels of particulate matter can cause reduced lung function, respiratory infections and aggravated asthma, while long-term exposure increases the risk of stroke, heart disease, chronic obstructive pulmonary disease and cancer. Ozone, nitrogen dioxide and sulphur dioxide are associated with respiratory conditions, including asthma, and can have systemic effects on the body, including oxidative stress and inflammation. Carbon monoxide is a well-known health risk, interfering with the oxygen-carrying capacity of the blood and can be deadly in high concentrations.

Some groups are more vulnerable to the health impacts of air pollution. Children, for instance, are more susceptible because they breathe more per pound than adults, and their airways are narrower, so irritation or inflammation can more easily cause obstruction. They are also more likely to have asthma or other respiratory illnesses. Older adults are also more at risk, especially if they have pre-existing heart or lung disease. People with diabetes are also more vulnerable, due to their increased risk of cardiovascular disease. Low-income communities and minority populations are also disproportionately exposed to air pollution and its adverse health impacts.

Air pollution can also have adverse effects on pregnancy outcomes, with evidence suggesting links to low birth weight and increased risk of diabetes, cognitive impairment and neurological diseases. The health risks of air pollution are not limited to outdoor air. Indoor air pollution, for example from wood smoke, can also have serious health impacts, including lung disease, asthma attacks, acute bronchitis and respiratory infections.

Learn about water pollution from poor sanitation

Water pollution from poor sanitation is a pressing issue that poses significant risks to human health and the environment. Unsafe water is linked to the transmission of various diseases, including cholera, diarrhoea, dysentery, hepatitis A, typhoid, and polio. Poor sanitation exacerbates the problem by providing a pathway for pathogens and contaminants to enter water sources.

Poor sanitation practices, such as inadequate wastewater treatment and improper waste disposal, contribute to water pollution. This includes insufficient management of urban, industrial, and agricultural wastewater, which results in the contamination of drinking water sources with chemicals, pathogens, and other pollutants. Inadequate sanitation infrastructure, particularly in low- and middle-income countries, further exacerbates the issue.

The impact of water pollution from poor sanitation is far-reaching. Firstly, it poses a direct health risk to individuals who come into contact with or consume contaminated water. Vulnerable populations, such as young children, are especially susceptible to waterborne diseases, which can be fatal. Additionally, poor sanitation during menstruation, pregnancy, and childcare can force women and girls to stay at home, impacting their education and economic opportunities.

Furthermore, water pollution from poor sanitation has economic implications. Diseases and infections caused by contaminated water can lead to income loss due to an inability to work or attend school. The costs of medical care and transportation can be burdensome, particularly for low-income households. Additionally, food shortages can occur when there is insufficient clean water for agriculture.

To address water pollution from poor sanitation, several interventions can be implemented:

• Improve sanitation infrastructure: Invest in building and upgrading sanitation facilities, ensuring that all communities have access to safe and adequate sanitation services.
• Promote proper waste management: Implement measures to reduce the discharge of untreated wastewater and minimize the release of hazardous chemicals and materials into water bodies.
• Enhance wastewater treatment: Prioritize the treatment and safe reuse of wastewater to prevent the spread of contaminants and reduce the volume of untreated wastewater discharged into the environment.
• Educate communities: Raise awareness about the importance of sanitation and hygiene practices, including handwashing, to prevent the spread of waterborne diseases.
• Implement integrated water resource management: Adopt a holistic approach to water management, including cross-sectoral coordination and cooperation, to address the complex nature of water pollution effectively.

Identify the sources of air pollutants

Air pollution is a serious issue that has existed since humans started burning materials for fuel, and it continues to kill millions of people prematurely every year. The main sources of air pollution can be divided into human-made and natural sources.

Human-made sources, which are responsible for most air pollution, include mobile sources such as cars, trucks, buses, and other vehicles, as well as stationary sources like factories, refineries, and power plants. These sources emit pollutants through smokestacks, stacks, and vents, with vehicles being the primary mobile source of air pollution in the United States. The federal government has played a significant role in reducing vehicle emissions by regulating car manufacturing and fuel production, such as removing lead from gasoline and reducing sulfur in diesel fuel.

In addition to these large-scale sources, there are also neighbourhood sources that contribute significantly to air pollution. These include local businesses, heating and cooling equipment, wood fires, and gas-powered yard and recreational equipment. Residential wood burning, in particular, has been increasing over time, with 55% of Minnesota's direct fine particle emissions attributed to this source.

Indoor air pollution is also a concern and can be caused by various factors such as new carpets, cleaning solvents, and even pets. An air quality monitor can help identify specific sources of indoor air pollution by measuring pollutants like PM 2.5 and VOCs.

Natural sources of air pollution include volcanic eruptions, forest fires, and wildfires, which can have both local and long-range impacts. While these sources may not create ongoing pollution problems, they can still have significant effects on air quality and human health.

To effectively tackle air pollution, it is crucial to identify the sources and focus on interventions that will have the biggest impact. By understanding the sources, we can implement measures to reduce emissions and improve air quality, ultimately reducing the health risks associated with air pollution.

Recognise the signs of water pollution

Water pollution is a widespread problem that jeopardizes our health and the environment. It is important to be able to recognize the signs of water pollution to ensure the health and well-being of the environment and communities that depend on these water sources. Here are some key indicators to look out for:

Unusual Water Colour and Odour

Changes in water colour, such as brown or green hues, or murky water, are common indicators of pollution. Additionally, any strong, unusual, or unpleasant odours emanating from the water could signal contamination. Some common smells that might indicate an issue include sewage, chemicals, sulfur, metallic, or chlorine-like odours.

Debris and Film on the Water Surface

An unusual amount of debris, such as trash, oil slicks, foam, or scum floating on the water's surface, can indicate pollution sources nearby. An oily film on the water is also a clear sign of pollution.

Dead or Dying Aquatic Life

While it is not uncommon to see an occasional dead fish in a local waterway, a sudden increase in dead fish or other aquatic life could indicate pollution affecting the food chain of the local ecosystem. A significant reduction in fish or other aquatic wildlife populations can also signal water pollution.

Unauthorized Discharges

Observe if there are any pipes or outlets discharging suspicious-looking substances directly into the water. Unauthorized dumping or industrial discharges of toxic chemicals can be a significant source of water pollution and should be reported immediately.

Sewage Incidents

In some cases, water pollution may be due to sewage overflows or leaks. Keep an eye out for toilet paper, wipes, tissues, sanitary products, or faecal matter in the water, which indicate a sewage incident.

If you suspect water pollution, it is important to avoid contact with the water and report your observations to the relevant environmental authorities or local water management agencies. You can also utilize resources such as the Surfers Against Sewage app or email saferseasservice@sas.org.uk to report pollution incidents.
