Summary
This review examines the environmental risks posed by synthetic textile dyes discharged into aquatic environments, with a focus on their persistence, toxicity, and potential impacts on ecosystems and human health. It surveys the current landscape of photocatalytic materials — including semiconductor-based catalysts — being explored as sustainable alternatives for dye removal and wastewater treatment. The paper is likely to identify research gaps and propose future directions for scaling up photocatalytic approaches in industrial effluent management.
UK applicability
Whilst the paper is international in scope and not UK-specific, the findings are relevant to UK water quality policy and industrial effluent regulation, particularly given ongoing pressures on water bodies from industrial and agricultural pollution under the Water Framework Directive and its domestic successor frameworks.
Key measures
Dye toxicity profiles; photocatalytic degradation efficiency; types of photocatalytic materials assessed; environmental risk indicators
Outcomes reported
The paper reviews the environmental and health hazards associated with synthetic textile dyes released into water systems, and evaluates the current status and efficacy of photocatalytic materials as sustainable treatment technologies for dye-contaminated wastewater.
