In a world increasingly driven by fast fashion and global trade, the clothes we wear often come at a hidden cost—one paid not only by exploited garment workers and the environment but by the wearers themselves. Mounting evidence reveals that many low-cost and second-hand garments, especially those exported to African countries, contain harmful chemicals that pose serious health and environmental risks. From skin irritations and hormonal disruptions to the pollution of rivers and soil, the consequences of toxic textiles are deeply alarming. As millions rely on second-hand clothing for affordability and style, the question arises: are we sacrificing our safety in the name of fashion?
Fast fashion garments are frequently treated with hazardous chemicals such as formaldehyde, azo dyes, phthalates, and heavy metals—used to preserve fabrics, enhance colours, or improve texture. These substances have been linked to severe health issues including cancer, respiratory problems, and endocrine disruption. A 2012 Greenpeace report, Toxic Threads: The Big Fashion Stitch-Up, found that many garments sold globally contained nonylphenol ethoxylates (NPEs), which degrade into toxic pollutants. The 2018 Changing Markets Foundation’s Dirty Fashion report and a 2021 Water Witness International study further underscored the prevalence of chemical pollution linked to textile production and waste, particularly in African regions.
Africa, a major recipient of second-hand clothing, finds itself at the frontline of this toxic influx. Millions of tonnes of used garments are imported annually, supporting vast resale markets. However, some of these clothes—rejected in their countries of origin for failing safety standards—contain dangerous levels of chemicals. A 2022 investigation by Kenya’s Centre for Environment Justice and Development (CEJAD) uncovered imported clothing with high concentrations of lead and formaldehyde. In Ghana’s Kantamanto market, traders have raised the alarm over increasing shipments of chemically treated, poor-quality clothing, as highlighted by The Or Foundation in 2021.
The effects on human health are becoming ever more evident. Wearers of contaminated clothing often experience rashes, allergic reactions, and chronic health problems. Environmental repercussions are equally dire; when these garments are washed, toxic chemicals leach into water sources, polluting rivers and farmlands. As most of these textiles are non-biodegradable, they contribute heavily to Africa’s growing waste crisis.
Environmentalists are calling for urgent reform, advocating for strict regulations on chemical use in textile production and comprehensive quality checks on clothing exports. While new garments often carry certifications like Oeko-Tex to assure chemical safety, extending such oversight to second-hand clothing remains a challenge. A multi-pronged approach is needed: establishing national testing programmes, forming partnerships with certified laboratories, enforcing import accountability, and investing in detoxification centres for used garments.
Public awareness is equally critical. Education campaigns can help consumers identify potentially hazardous clothing and shift demand toward ethical, sustainable fashion brands committed to non-toxic materials and fair production practices.
The fashion industry’s toxic legacy is a global concern with local consequences. Unless governments, brands, and consumers unite to tackle the hidden dangers in our clothing, millions will continue to be exposed to substances that endanger health and devastate the environment. It is time for the global fashion system to prioritise safety, sustainability, and accountability—because fashion should never come at the cost of human wellbeing.
