Due to several health benefits, milk is considered as a complete food that contains all the vital nutrients. Earlier, every person drinks the purest milk and so, extracts many nutrients from the milk. But, we cannot get the essential nutrients from the contaminated milk, whereas, drinking of pure milk is just like a dream now a day’s. Milk is lacking so many healthy nutrients and further some more nutrients are also eliminated during the processing methods in the milk dairies. Moreover, dairy cows are injected with a chemical named oxytocin, a hormone that used to increases the production of milk in cattle. Oxytocin or Pitocin injections are given to the pregnant women for inducing artificial labor, but commercially oxytocin injections are used over the cattle, two times in a day, in tabelas. After injecting the chemical hormone, the stored milk in the udder of the animal released, and giving extra liters of milk. This hormone contracts the uterus of animal causes severe pain each and every time when it is injected into the cattle’s body and its prolonged use causes neurological problems, difficulty in conception that may lead to infertility and with regular use, the cattle loses the control over udder which gets inflamed and infected with the pus and reduces the life expectancy. However, the government of India has banned the use of oxytocin injection on animals because of its several negative health issues under section 12 of Food and Drug Adulteration Act, 1960 and the Prevention of Cruelty to Animals act. But the rules and regulations exist only on the papers because the milkmen, villagers, and farmers do not follow the regulations and still grabbing the profit by getting the injections from the chemist’s shops without any prescriptions of veterinary doctor and it is quite miserable in India. The injected oxytocin reaches into the human body through the consumption of milk and causes several side effects in men, women and children, such as- Early puberty in girls, Gynecomastia (female-like features in male), Hormonal imbalance in children, cardiovascular problems, including cardiac arrhythmia, increased or decreased blood pressure, premature ventricular contraction etc., irregular monthly cycle in girls and women, loss of vision, renal diseases, memory loss, breast cancer and also impotency in males.
Milk dairies do not perform this test, however; boiling before consumption is the best option in order to reduce the traces of oxytocin. To minimize the negative effects of oxytocin boiling of even pasteurized milk is recommended.

Silver foil also known as Chandi varak, are the edible silver leaves with no flavour and are used for garnishing the sweets in South Asian cuisine. It is generally used in India for decorating sweets, confectionery, desserts, and dry fruits like almonds, cashew nuts, and dates. In the market, cardamom- coated sweets are also commonly available. These leaves are not specific to the Indian cuisine, but Japan and European countries are also used this precious metal leaf to garnish food, and as an additive in special drinks. Varak is made of pure metal such as silver for silver foil and sometimes gold is used to prepare gold foil. For the preparation of varak, intestines of the cattle/ox are used because of its great elasticity that cannot be cut after a severe beating. It can be obtained from the slaughtering houses and further, its separation is much easier from an animal tissue than to separate from any other paper technology.
The intestines are pulled, washed in the slaughtering houses in order to remove blood and other remains of the intestine and given to the varak manufacturers. These intestinal guts are cut into the smaller pieces, blocks of silver is placed in between the bound layers of the intestines and keep this in a bag of leather followed by sealing. This bag is then beaten, with the help of wooden sticks, until the silver block is flattening out and turned into silver foil. This foil is separated from the intestinal pack and will be placed on papers. The prepared extremely thin leaves are brittle and break into smaller pieces and get stuck to the hands. These are odourless and tasteless that is why these are used for garnishing purposes to enhance good appeal which shows a symbol of royalty and prosperity for the family. Gold and silver food leaves are certified by the European Union, as E175 and E174 additives respectively. These are safe with purity near to 100% with 0.1% standard deviation, but it is extremely difficult to check the purity and that is why the manufacturers are making ‘profit’ by compromising the quality of the leaves. India has the great market for vark but do not have any control regulations in order to check the quality of these edible ‘foils’. Several cases of ‘poor’ quality of silver and replacing of silver foil with aluminium foil have been reported. So, precaution must be taken while enjoying the silver coated sweets because consumption of these low-quality sweets causes severe illness in the body. The easiest way to check out the difference in between the two- aluminium leaves residue get stuck to the hands on wiping the top layer of the sweet.
Negative effects of consuming silver leaves:
The preparation process of silver foil may leave the traces of blood and flesh on the leaves.
The manufacturing process is highly unhygienic and unhealthy.
There are chances of contamination are high if the leaves prepared from the infected and diseased animal.
Consuming this causes throat and lung problems, stomach pain and several infections.

Anything which is present in the marine environment that causes harm is known as pollution. There are different types of pollution in the sea like plastic wastes, oil, chemicals, agriculture and industrial wastes and sewage waste as these pollutants can interfere with the life cycle of several aquatic lives. The largest natural water body on the Earth are oceans, which provide habitat to the various animals and plants, but due to a variety of human activities, the marine life is now adversely affected by the marine pollution. Now, it is the responsibility of each and every citizen of the world in keeping the natural water bodies neat and clean so that the aquatic life can grow and flourish well.
Pollution enters into the water bodies by different ways:-
Sewage waste: Sewage polluting waste directly enters into the ocean by sewage, rivers or drainages. This toxic waste reduced the oxygen levels in the water and so decreases the chances of survival of the marine life.
Industrial toxic waste: Disposing of the toxic liquid into the ocean, as a source of industrial and agricultural waste, create ocean pollution that adversely affects the aquatic life. As the temperature of these hazardous chemicals is high, they alleviate the ocean temperature also known as thermal pollution which directly affects the marine life. These chemicals deposit in the internal tissues of the animals, leading to infertility. Aquatic plants and animals cannot exist at elevated temperatures and ultimately collapse. It also affects the process of photosynthesis by stopping of sunlight.
Through oil spills: Oil spill is the most destructive and it is a great source of pollution in the ocean. Crude oil has existed for several years in the sea water and is highly toxic to aquatic life, marine animals died due to suffocation and it is very difficult to clean. Ships are also responsible for the noise pollution, which disturbs the life cycles of aquatic lives.
Littering: It is the huge source of water pollution in the ocean, it occurs when the garbage, including plastic debris, polythene bags, man-made waste are blown through the wind. This waste cannot degrade and remains suspended in the water for years. Small animals got confused and caught the plastic waste for the food and died slowly over a period of time and these small animals later eaten up by the big animals. Animals that died in the majority due to this plastic waste include seabirds, sea turtles, fishes, sharks, crabs, seahorse, starfish, jelly fish, dolphins, crocodiles, penguins, etc. Further, the contaminated aquatic animals are then eaten up by the humans, gets accumulated in their body that leads to cancer, infertility and birth defects. Thus, ocean pollution severely affects the entire food chain.

In our daily life colour is an important aspect as we all love to wear colourful clothing and eat rainbow diet. Dyes may be defined as substances that, when applied to a substrate gives colour. Such substances with considerable coloring capacity are widely employed in the textile, leather, carpets, pharmaceutical, food, cosmetics, plastics, photographic and paper industries. The dyes can stick to compatible surfaces through solution, by forming a covalent bond or complexes with salts or metals, by physical adsorption or by mechanical retention.
The textile dyeing industry has generated immeasurable pollution as it is one of the most chemically demanding industries and is the biggest consumer of dye substances. Textile industries expend a huge supply of water and chemicals due to which about 10-15% dyes are liberated into the environment during the dyeing process making the industrial effluents vastly coloured and aesthetically unacceptable and are frequently imported into the environment. Over exposure to these reactive dyes (especially when they are in powdered form), may cause health hazards like respiratory problems due to inhalation of dye particles; it is known as respiratory sensitization to the workers therefore, all these chemicals and dyes must be handled with care. Some other symptoms of respiratory sensitization include skin irritation, watery and sore eyes, itchy or blocked nose, sneezing and symptoms of asthma such as coughing and wheezing. Harmful chemicals include formaldehyde-based resins, ammonia, acetic acid, some shrink-resist chemicals, some optical whiteners, soda ash, caustic soda and bleach. Dyes containing anthraquinone or azo structures are familiar to cause contact dermatitis. Generally azo dyes are considered as a deadly poision, dangerous to work and greatly inflammable. Now a day’s chemical used to yield dyes are usually extremely toxic, carcinogenic, or even explosive. Such type of clothing is also hazardous for babies and kids when they are in prolonged contact with these chemicals; actually these harmful substances are absorbed through the skin, particularly, when their body is warm.
Even its small concentrations in the water disturb the photosynthetic activity of algae by absorption and reflection of light which serious influence on the food chain.
Dyes also have undesirable side effects on exposed organisms as their small concentration (less than 1 ppm) is greatly visible due to their brilliance.
Dyes can remain in the atmosphere for a long time due to its high thermal and photostability characteristics.
Dyes and their residues are carcinogenic, mutagenic or toxic to life.

Crack-Tip Opening Displacement Test is carried out to test the Fracture toughness in order to check whether a material is fit for tough working conditions or not. It measures the deformation before undergoing failure in a pre-cracked sample. Spectro has developed skills to carry out CTOD test efficiently as per BS 7448 Standard.
It is practiced on those materials which undergo plastic (irreversible) deformation before it encounters failure. The testing material resembles the original one, but the dimensions can be reduced proportionally.
The crack tip opening can be calculated from the depth of the crack and opening at the mouth of the notch. Depending on the material used, the fracture can be brittle or ductile that can be concluded from the graph.
