Why in news
A review of 177 studies suggests that the combined impact of endocrine-disrupting chemicals (EDCs) and climate change may be a primary driver of global fertility decline.
Background
The study identified phthalates and PFAS (per- and polyfluoroalkyl substances) as key endocrine-disrupting chemicals found in consumer goods. Research indicates these chemicals, alongside climate impacts, disrupt hormones and environmental sex determination across various species.
Facts for Prelims
- S&TPhthalates and PFAS are identified as endocrine-disrupting chemicals (EDCs) linked to reproductive issues.
- FactThe study reviewed a total of 177 research papers to establish the link between toxins, climate, and fertility.
- S&TEndocrine-disrupting chemicals can impact environmental sex determination in various species.
For Mains
Q. Discuss how the synergy between chemical pollution and climate change poses a significant threat to global reproductive health and biodiversity.
Dimensions to cover in your answer
- Endocrine disruption: Chemical interference with hormonal pathways and reproductive systems
- Environmental sex determination: Climate-induced shifts in species-specific reproductive viability
- Regulatory gap: Lack of stringent oversight on PFAS and phthalates in consumer goods
Keywords: Endocrine disruptors · Reproductive health · Climate-health nexus · Bioaccumulation · Environmental toxicology
