✔ DCA (Dichloroacetic Acid) kya hota hai?

Ek chlorinated organic acid

Formula: CHCl₂COOH

Colorless, sharp-smelling liquid

Water me easily dissolve ho jata hai

---

✔ Kaise banta hai?

Chloroacetic acid

Dichloroacetic acid (DCA)

Trichloroacetic acid (TCA)

---

✔ Kyu harmful hai?

Carcinogenic concerns (animal studies)

Liver toxicity

Drinking water standards me HAAs ka limit rakha gaya hai

(US EPA: HAA5 < 60 µg/L)

---

✔ Water treatment me problem?

DCA persistent hota hai

Chlorinated nature ki wajah se oxidation difficult hota hai

Advanced Oxidation Processes (AOP) me iska EE/O ≈ 15 kWh/1000 gal/order hota hai

→ moderate difficulty to decompose

✔ Summary (easy language)

> DCA ek chlorinated acid hai jo drinking water me chlorine disinfection ke side-product ke roop me milta hai, aur health ke liye harmful maana jata hai.

Agar chaho to main HAAs (HAA5) ke short notes bhi bana du exam style me.
