A recent study has highlighted a concerning link between Di(2-ethylhexyl) Phthalate (DEHP) exposure and increased risk of heart disease-related deaths. As this compound is found in many everyday items, this raises public health and regulatory concerns.
What is DEHP?
Also known as: Bis(2-ethylhexyl) phthalate.
Nature: It is a colorless, nearly odorless liquid that doesn't evaporate easily.
Primary use: Added to plastics to make them flexible and durable.
Solubility: Dissolves more in organic materials like gasoline, paint removers, and oils, and less in water.
Where is DEHP Found?
DEHP is prevalent in a wide range of household and industrial products:
Food packaging and storage containers
Medical devices like IV bags and tubing
Personal care products such as shampoos and lotions
Children’s toys and plastic wraps
Health Concerns Linked to DEHP
Cardiovascular Impact: Studies have linked DEHP exposure to heart disease-related mortality.
Endocrine Disruption: DEHP is known to interfere with hormonal functions.
Reproductive Toxicity: It particularly affects the developing fetus and male reproductive system.
Long-term Risks: May contribute to metabolic disorders, liver toxicity, and developmental abnormalities.
Relevance for UPSC
GS Paper 3 – Environment and Health: DEHP falls under the category of Endocrine Disrupting Chemicals (EDCs).
It highlights the intersection of toxicology, public health, and consumer safety regulations.
Awareness of such chemicals is important in the context of Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health) and SDG 12 (Responsible Consumption and Production).
UPSC Prelims Question
Consider the following statements regarding Di(2-ethylhexyl) Phthalate (DEHP):
It is used as a plasticizer in various consumer products.
It readily evaporates and causes air pollution in industrial areas.
DEHP exposure has been linked to cardiovascular and reproductive health issues.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 1 and 3 only
(c) 2 and 3 only
(d) 1, 2 and 3
Answer: (b) 1 and 3 only
Explanation:
Statement 1 is correct – DEHP is widely used to soften plastics.
Statement 2 is incorrect – DEHP does not evaporate easily and is less likely to pollute air.
Statement 3 is correct – Research shows adverse effects on the heart and reproductive system.
UPSC Mains Question
Examine the implications of widespread use of endocrine-disrupting chemicals like DEHP in consumer products. What measures should India adopt to regulate and reduce their impact on public health? (GS Paper 3)
