Polluted Water, Air: Toxic Sports Apparel?

Water and air pollution have a significant impact on sports apparel, from the manufacturing process to the health of athletes and spectators. The production of clothing often involves water pollution and the use of harmful chemicals, which can have long-lasting effects on the environment. In terms of air pollution, poor air quality can negatively affect the performance and health of athletes, referees, and spectators, with athletes being particularly vulnerable due to their increased breathing rate during exercise. Additionally, the burning of fossil fuels, agricultural work, and emissions from factories contribute to air pollution, which can have serious health consequences for individuals with respiratory conditions. Overall, the intersection of water and air pollution with sports apparel is a complex issue that requires further research and sustainable solutions.

Water pollution during the dyeing process

Water pollution is a significant issue in the sports apparel industry, and the dyeing process is a major contributor. During this stage, large volumes of water are used, and the resulting wastewater is often contaminated with harmful chemicals and dyes. This toxic soup is then discharged into nearby water bodies, causing widespread ecological damage and threatening the health of surrounding communities.

The dyeing process in the textile industry consumes vast amounts of water, with an estimated 200 tonnes of water used per tonne of fabric. However, the majority of this water is returned to nature as toxic waste. The wastewater contains residual dyes, hazardous chemicals, mordants, and microfibres, which are released into water streams without proper treatment. This issue is exacerbated by the lack of regulation and enforcement surrounding wastewater disposal, allowing big brands and factory owners to evade accountability.

One of the main culprits of water pollution during the dyeing process is the use of synthetic dyes, such as disperse, reactive, acid, and azo dyes. Azo dyes, in particular, are popular due to their ability to achieve vivid colours at lower temperatures. However, they have been listed as carcinogens, and under certain conditions, they can break down into potentially dangerous substances known as aromatic amines. These amines are harmful to humans and can pollute water systems, despite legislation prohibiting the sale of products containing these dyes in some countries.

The impact of this water pollution is devastating. Communities living near rivers in high garment-exporting countries like China and Bangladesh are unable to access clean water, as their rivers are contaminated with toxic chemicals. This has led to decreased life expectancies and increased health problems for these vulnerable populations. Additionally, the groundwater is contaminated, rendering wells unsafe for domestic use.

To address this issue, alternatives to current dyeing methods and regulations for water processing must be implemented. While natural dyes derived from plants, seeds, fruits, and insects have been suggested, they are not a simple solution. Natural dyes also require large amounts of water and often need the use of chemical mordants to fix the colour, which can lead to similar pollution problems as synthetic dyes.

The fashion industry's demand for colour shows no signs of diminishing, and with production levels continuing to rise, the pressure on water systems will only increase. It is crucial that brands take responsibility for their supply chains, invest in infrastructure to process wastewater properly, and reduce their endorsement of fast fashion to minimise their impact on the environment and the communities affected by their practices.

Air pollution from the burning of fossil fuels

The impact of air pollution from fossil fuels on the sports apparel industry is significant. Sports apparel and footwear have a heavy carbon footprint due to pollution, the consumption of non-renewable resources, and waste associated with manufacturing. The burning of fossil fuels contributes to the carbon footprint of the apparel industry, which includes the emissions produced during the manufacturing and distribution of sports clothing and gear.

The health consequences of air pollution from fossil fuels are dire, with approximately one in five deaths worldwide attributed to this type of pollution. In 2018, over 8 million people died from the health effects of fossil fuel pollution, a number that is more than double previous estimates. The vulnerable groups in society, such as children, older individuals, those on low incomes, and people of color, are disproportionately affected by the harmful impacts of air pollution.

The pollutants released from burning fossil fuels, such as ground-level ozone, particulate matter (PM2.5 or PM10), NO2, carbon monoxide, lead, and sulfur dioxide, have detrimental effects on human health. These pollutants can cause and exacerbate respiratory conditions, cardiovascular disease, cancer, tissue damage, and asthma. Athletes, due to their higher breathing rate and increased airflow velocity during exercise, are particularly vulnerable to the effects of air pollution. Research has shown that air pollution can negatively impact athlete performance and longevity, with elite sportspeople noticing a correlation between air quality and their health.

To address the issue of air pollution from the burning of fossil fuels, sports organizations, and venues can take several measures:

• Measure air quality: Sports organizers can proactively measure air quality before events and schedule matches during times of better air quality. Monitoring air quality can help identify optimal training and competition periods with lower pollution levels.
• Clean transport policy: Incentivizing the use of public transport or providing free transport for ticket holders can help reduce vehicle emissions, a significant source of air pollution around sports venues.
• Venue modifications: Transforming venues into domed facilities can reduce the impact of outdoor air pollution on athletes and spectators during matches.
• Collaboration with local authorities: Working with local governments can help improve air quality in the vicinity of sports venues, benefiting the health of players and fans.

In conclusion, air pollution from the burning of fossil fuels has far-reaching consequences for the sports apparel industry and beyond. It affects the environment, the health of individuals, and the performance of athletes. By implementing measures to reduce air pollution and transition to renewable energy sources, the sports industry can play a crucial role in mitigating the impacts of climate change and improving the well-being of those involved in sports.

Water pollution from cotton farming

Cotton is a water-intensive crop, requiring approximately 7,000 to 10,000 liters of water to produce one kilogram of cotton. This demand places immense pressure on water resources, especially in arid and semi-arid regions where cotton is often grown. Cotton farming accounts for 2.6% of the world's cultivated land but uses up to 10% of the world's agricultural water.

Cotton's high water consumption has severe environmental impacts, including water pollution. The diversion of water for cotton growing has severely impacted major ecosystems such as the Aral Sea in Central Asia, the Indus Delta in Pakistan, and the Murray Darling River in Australia. The excessive use of water in cotton cultivation frequently causes environmental problems such as waterlogging, salinization, and habitat damage.

Cotton cultivation also involves the use of agrochemicals, particularly pesticides, which contribute to water pollution. The runoff of pesticides, fertilizers, and minerals from cotton fields contaminates rivers, lakes, wetlands, and underground aquifers. These pollutants affect biodiversity directly through immediate toxicity or indirectly through long-term accumulation.

Cotton farming's water pollution has severe consequences for ecosystems and biodiversity. It threatens food security and the livelihoods of those dependent on these natural resources.

To address these issues, organizations like the World Wildlife Fund (WWF) promote sustainable cotton production and the adoption of better farming practices. The Better Cotton Initiative, supported by WWF, encourages farmers to minimize the harmful impact of crop protection practices, use water efficiently, and care for soil and water health. These efforts aim to reduce the environmental footprint of cotton farming and mitigate its negative impacts on water resources and ecosystems.

Air pollution from factories and industry

Sources of industrial air pollution include factories, power plants, and various industries such as petrochemicals, steelmaking, and waste disposal. These sources release pollutants such as carbon dioxide, methane, nitrous oxide, and fluorinated gases, which contribute to global warming and climate change. For example, the burning of fossil fuels releases carbon dioxide, a major greenhouse gas, into the atmosphere, leading to rising temperatures worldwide.

The impact of air pollution from factories and industry is far-reaching. It can cause respiratory illnesses, heart disease, lung cancer, and respiratory diseases such as emphysema. Young children, older adults, and athletes are particularly vulnerable to the effects of air pollution due to their higher breathing rates and more sensitive immune systems. Additionally, air pollution can have economic consequences, as it affects the productivity of workers, including professional sportspeople, and increases healthcare costs for treating pollution-related illnesses.

Furthermore, air pollution from factories and industry can have a direct impact on sports apparel. The manufacturing process of sports clothing and footwear contributes to air pollution, particularly through the release of greenhouse gases and the use of non-renewable resources. This pollution can also affect the performance and longevity of athletes, as they inhale harmful pollutants during training and competitions, which may impair their health and cognitive function over time.

To mitigate the effects of air pollution from factories and industry, several measures can be implemented:

• Transition to cleaner energy sources: Reducing the reliance on fossil fuels and transitioning to renewable energy sources, such as solar, wind, or hydropower, can significantly decrease air pollution levels.
• Improve waste management: Proper waste disposal and recycling practices can help reduce the amount of hazardous waste generated by industries, minimizing the release of toxic pollutants into the atmosphere.
• Implement pollution control technologies: Industries can invest in advanced technologies, such as scrubbers, electrostatic precipitators, and fabric filters, to capture and remove pollutants from industrial emissions before they are released into the atmosphere.

This includes using recycled materials, minimizing waste, and optimizing production methods to reduce energy consumption.

Air pollution affecting athlete performance

Air pollution is a serious issue that can have detrimental effects on athlete performance and health. The combination of exercise and exposure to pollutants can result in a range of negative consequences, including respiratory distress, impaired performance, and even long-term health problems.

Respiratory Distress

Athletes who train and compete in areas with high levels of air pollution are at risk of inhaling toxins and dust particles, which can lead to inflamed airways, diminished pulmonary capacity, and respiratory ailments such as coughing, wheezing, and shortness of breath. This can affect their endurance and ability to focus during training and competitions. Even on days with relatively low pollution levels, athletes can be affected due to their deep inhalation of air, forcing it into their lower respiratory system where smog particles and ozone toxins accumulate over time.

Performance Impairment

Air pollution can have a direct impact on athlete performance, as suggested by a growing body of research. For example, a study by World Athletics, the sport's international governing body, found that athletes are disproportionately affected by air pollution due to their higher breathing rate and increased airflow velocity during exercise. The combination of exercise and exposure to pollutants such as sulfur dioxide or ozone has been shown to cause bronchoconstriction and reduced ventilatory flow. In sports where milliseconds and millimeters determine success, even slight reductions in an athlete's strength and speed due to air pollution can be the difference between winning and losing.

Long-Term Health Problems

Prolonged exposure to air pollution during training and competitions can also lead to long-term health issues for athletes. Polluted environments put athletes at risk for chronic heart and lung disease. Immediate effects of pollutants like carbon monoxide include depleted oxygen to the tissues, increased heart rate, and elevated blood pressure. More severe consequences such as asthma, pulmonary hypertension, and cardiovascular disease may develop over time. Young athletes are particularly vulnerable, with research suggesting that children participating in outdoor sports in polluted communities have a higher risk of developing asthma.
