A research team came up with the findings after collecting and testing food samples from a few randomly selected capital markets. The survey report read that nearly 40% of 82 samples contained banned pesticides such as DDT, Aldrin, Chlordane and Heptachlor. The amounts of pesticides in these samples were found to be 3 to 20 times greater than the standard limits. Around 50% of vegetables and 25% of fruits were found to be contaminated with an unsafe level of pesticides. Analysing more than 30 samples of turmeric powder, the team also found that nearly 30% of the samples contained traces of Lead Chromate, which can be fatal if swallowed or inhaled. Using the HPLC method, 66 samples were analyzed for the presence of fomaldehyde, Adulteration was thereby detected in samples of coriander, mango and fresh shrimps. Samples of chicken and fish contained traces of antibiotics. High microbial populations were found in several samples of pasteurized milk, indicating poor processing procedures by the manufacturers. Samples of cucumber and street foods also showed high microbial populations, suggesting widespread contamination in the water supply. Experts suggest that instead of focusing only on the end products, the issue should be addressed at the root level. Better monitoring and supervision in the production process farmer, transport, wholesale, and retail trader - are mandatory for minimizing food adulteration. Adulterated food products are reportedly the cause behind thousands of people suffering from fatal diseases like cancer, kidney failure and heart problems.

Henson, a black man, was the only person to accompany Peary on all of the explorer's Polar expeditions. At first Peary doubted that Henson could endure the arctic climate. During the eighteen years these two attempted to reach the Pole, Henson's unfailing good humor and courage helped Peary to move on. Eskimos of Smith Sound greeted Henson as a brother, welcomed him into their stone igloos, and taught him their difficult language. Soon Henson became the most proficient of Peary's men, not only in speaking Innuit but also in handling a dog team. On later expeditions it was he who taught greenhorns how to drive a dog team and how to survive in the sub-zero climate. Beloved by the Eskimos, who called him "Miy Paluk", he persuaded them to accompany Peary into the uncharted regions where they believed evil spirits dwelled. On a nearly disastrous excursion across the ice cap in 1895, Henson twice saved Peary's life. Again and again Henson proved that he was capable of endurance and achievement, the final test coming in 1909 when he accompanied Peary and four Eskimos on the last lap of the successful dash to the pole. Greenhorns were -
