Synthetic Dyes, Heavy Metals, and Other Hazardous Materials for the Environment
Summary
Researchers reviewed the environmental and human health burdens imposed by synthetic dyes, heavy metals, pesticides, and microplastics across industrial sectors, documenting how each contaminant class enters food chains and accumulates in ecosystems and human tissue through distinct but overlapping pathways.
The world is entangled in a web of toxic materials that once fueled industrial progress but now threaten the very ecosystems they rely on. In textiles, agriculture, and cosmetics, among other sectors, synthetic colors, heavy metals, pesticides, and microplastics have seeped in, causing environmental destruction and endangering human health. Though formerly appreciated for their strength and vivid hues, synthetic dyes are now associated with harmful discharge, carcinogenic degradation, and disturbance of ecosystems. It is detrimental to both the environment and humans for heavy metals to linger in soils and water, enter food chains, and accumulate. Pesticides are killing biodiversity and poisoning vital water supplies while boosting agricultural output. Oceans and marine life are contaminated by microplastics, which then enter our bodies and the food chain.
