The ancient town of Korkai near present-day Thoothukudi has been a centre for maritime trade and pearl fishery for more than 2000 years. Ptolemy's geography refers to Korkai as a centre of pearl fishery while describing commercial relations between western India and Alexandria, the chief eastern emporium of the Roman Empire. The Periplus says that the Pandyan kingdom extended from Comari towards the north, including Korkai, where the pearl fisheries were.
Thoothukudi was the seat of Portuguese during the 16th century, and the Dutch occupied in the 17th century as evidenced by Pagoda coins. During the 18th century the British overpowered and occupied the town. Being a port town, the town received attention from the rulers for improving their trade, and so it was brought to Municipal status in 1866. Rao Bahadur Cruz Fernandez and J. L. P. Roche Victoria as the chairmen of municipal corporation made significant contributions, laying the foundations for a modern Thoothukudi.
On 20 October 1986, a new district, carved out of the erstwhile Tirunelveli district was born in Tamil Nadu and named after V. O. Chidambaranar, a prominent national leader hailing from Ottapidaram who led the Swadeshi Movement in the south. Since 1997, as is the case in other districts of Tamil Nadu, this district has been named after its headquarters town, Thoothukudi.
Thoothukudi became the citadel of freedom struggles in the early of the 20th century.

Respondents of the study had various health issues like skin diseases, eye irritation, Asthma, Allergy, Respiratory problems, Cancer & Hypertension. . The study also observed that Industrial disposals and other chemical contaminates that enter waterways through agricultural runoff, storm water drains, and industrial discharges may persist in the environment for long periods and be transported by water or air over long distances. They disturbed the function of the endocrine system, resulting in reproductive, developmental, and behavioral problems. The endocrine disrupters reduced the fertility and increased the occurrence of still births, birth defects, and hormonally dependent Cancers such as breast, testicular, and prostate cancers. The effects on the developing nervous system can include impaired mental and psychomotor development, as well as cognitive impairment and behavior abnormalities.
