Impressions of chromium sludge.
Impressions of chromium sludge at a chromium recovery plant in Jajmau in Kanpur, India. Kanpur is one of the most polluted cities in India and has been the hub for leather production since the British established tanneries in the 19th century. More than half of the tanneries in Kanpur are illegal and operate outside the pollution control regulations. They release chromium toxins as a waste by-product.
