Tribal fishermen in Tamil Nadu suffer dangerous lead exposure, study finds

By Jag Jivan

A new peer-reviewed study published in the Journal of Trace Elements in Medicine and Biology has revealed alarmingly high levels of toxic metals, particularly lead, among tribal fishermen in the Pichavaram mangrove region of Tamil Nadu.

The research, titled “Elevated blood lead and metal levels among occupationally exposed tribal fishermen in Tamil Nadu, India”, was conducted by Dhananjayan Venugopal, Ravichandran Beerappa, Panjakumar Karunamoorthy, Jawahar Salavath, Mala Ambikabathy, Shridhar Kondhalkar, Gopalakrishnan Ayyaru, and Thamaraikannan Mohankumar.

Analyzing blood samples from 53 fishermen, the researchers found concentrations of chromium, copper, manganese, nickel, lead, and zinc that far exceeded international reference values. Of particular concern were the blood lead levels: 74 percent of participants had levels above the US Centers for Disease Control and Prevention’s (CDC) reference of 5 μg/dL, 55 percent surpassed the American Conference of Governmental Industrial Hygienists’ (ACGIH) biological exposure index of 20 μg/dL, and 15 percent exceeded the Occupational Safety and Health Administration’s (OSHA) threshold of 40 μg/dL. Fishnet makers, who directly handle lead-based sinkers, recorded the highest mean blood lead levels at 269 μg/L.

“This study is the first to document blood lead levels among Indian tribal fishermen,” the authors wrote. “Our findings indicate significant occupational exposure to toxic metals, with concentrations notably exceeding international reference values. Immediate interventions, such as promoting personal protective equipment (PPE), stricter regulations, and educational programs, are essential to safeguard this vulnerable population.”

The researchers further warned that the absence of protective measures has exacerbated the risks. “Non-users of PPE exhibited higher metal burdens,” they observed, adding that urgent policy action is required to reduce exposure in one of India’s most marginalized fishing communities.

By highlighting the occupational hazards of lead and metal exposure in the Pichavaram region, the study provides critical evidence for policymakers and public health officials. As the authors concluded, “Tribal fishermen in Pichavaram face significant health risks from elevated toxic trace metal exposure, especially lead. This pioneering study underscores the need for effective public health policies to safeguard fishing communities.”

Plastic burning in homes threatens food, water and air across Global South: Study

By Jag Jivan In a groundbreaking study spanning 26 countries across the Global South , researchers have uncovered the widespread and concerning practice of households burning plastic waste as a fuel for cooking, heating, and other domestic needs. The research, published in Nature Communications , reveals that this hazardous method of managing both waste and energy poverty is driven by systemic failures in municipal services and the unaffordability of clean alternatives, posing severe risks to human health and the environment.

Economic superpower’s social failure? Inequality, malnutrition and crisis of India's democracy

By Vikas Meshram India may be celebrated as one of the world’s fastest-growing economies, but a closer look at who benefits from that growth tells a starkly different story. The recently released World Inequality Report 2026 lays bare a country sharply divided by wealth, privilege and power. According to the report, nearly 65 percent of India’s total wealth is owned by the richest 10 percent of its population, while the bottom half of the country controls barely 6.4 percent. The top one percent—around 14 million people—holds more than 40 percent, the highest concentration since 1961. Meanwhile, the female labour force participation rate is a dismal 15.7 percent.

Swami Vivekananda's views on caste and sexuality were 'painfully' regressive

By Bhaskar Sur* Swami Vivekananda now belongs more to the modern Hindu mythology than reality.

History, culture and literature of Fatehpur, UP, from where Maulana Hasrat Mohani hailed

By Vidya Bhushan Rawat* Maulana Hasrat Mohani was a member of the Constituent Assembly and an extremely important leader of our freedom movement. Born in Unnao district of Uttar Pradesh, Hasrat Mohani's relationship with nearby district of Fatehpur is interesting and not explored much by biographers and historians. Dr Mohammad Ismail Azad Fatehpuri has written a book on Maulana Hasrat Mohani and Fatehpur. The book is in Urdu. He has just come out with another important book, 'Hindi kee Pratham Rachna: Chandayan' authored by Mulla Daud Dalmai.' During my recent visit to Fatehpur town, I had an opportunity to meet Dr Mohammad Ismail Azad Fatehpuri and recorded a conversation with him on issues of history, culture and literature of Fatehpur.

UP tribal woman human rights defender Sokalo released on bail

By A Representative After almost five months in jail, Adivasi human rights defender and forest worker Sokalo Gond has been finally released on bail.Despite being granted bail on October 4, technical and procedural issues kept Sokalo behind bars until November 1.

Sokalo's release follows the earlier releases of Kismatiya and Sukhdev Gond in September. "All three forest workers and human rights defenders were illegally incarcerated under false charges, in what is the State's way of punishing those who are active in their fight for the proper implementation of the Forest Rights Act (2006)", said a CJP statement.

Would breaking idols, burning books annihilate caste? Recalling a 1972 Dalit protest

By Rajiv Shah A few days ago, I received an email alert from a veteran human rights leader who has fought many battles in Gujarat for the Dalit cause — both through ground-level campaigns and courtroom struggles.
