Many pesticides and chemicals are not biodegradable, and due to bioaccumulation, can enter into food chain and ultimately affect human and animal health. Environmental exposure of pesticides to humans through ecosystems may be during cropping/ agriculture practices, consumption of food materials or air inhalation etc. Without pesticides or agricultural chemicals (herbicides, insecticides, rodenticides, fungicides and plant growth regulators), crop yield could drop by as much as a third and food prices would increase by as much as 75%. In India, 145 pesticides are registered for use at present and production has increased to approximately 85,000 metric tones. Though consumption in India is just about 0.5 kg/ha, but 51% food commodities are contaminated pesticide residues. Toxicity of pesticide is measured according to a number of indices (such as oral and dermal LD50) based on tests carried out on laboratory animals. They act mainly on receptors. In agriculture, mixing-loading step is the most contaminated task in open field accounting for two-thirds of the total daily exposure. Adverse health effects include acute and persistent injury to the nervous system, lung damage, injury to reproductive organs, and dysfunction of the immune and endocrine systems, birth defects and cancer. Even small amounts of some of these chemicals cause death; disrupt hormones and reduce the ability to successfully reproduce; and have been associated with specific cancers. Better understanding of the patterns of exposure, the underlying variability within the human population, and the links between the animal toxicology data and human health effects will improve the evaluation of the risks to human health posed by pesticides. Improving epidemiology studies and integrating this information with toxicology data will allow the human health risks of pesticide exposure to be more accurately judged by public health policy makers. There is need to educate all farmers for judicious use of pesticides, use of biotechnology and bio-pesticides, use of pesticides obtained from natural products such as Azadirachta indica (neem) via proper application of integrated pest management (IPM) programs would positively reflect on human health, agriculture, biodiversity and ecosystem management to minimize environmental problems caused by pesticides.

Antibiotics are defined as a category of natural, semi-synthetic or chemical compound with anti-microbial activity, which is extensively used to control and prevent for infectious diseases in animals and humans, and may be added in the feed as growth promoters to promote the growth and development of animals. Until recently, the main concern about inclusion of antibiotics as supplements in animal feeds is connected to antibiotic residues in products (milk, egg and meat) developed from the treated animals. These residues may cause a range of side effects such as immunopathological effects, transfer of antibiotic resistant bacteria to humans, mutagenicity, allergy, hepatotoxicity, reproductive disorders, nephropathy, bone marrow toxicity and even carcinogenicity. One of the most significant adverse effect of antibiotic residues is the transfer of antibiotic resistant bacteria to the humans due to the mobile properties of resistance. The rising use of antibiotic consumption in India is reflected through emerging drug resistance problem and regulations for the use of antibiotics in animals and human are still very poor. The unnecessary use of antibiotics in food producing animals is contributing to the antibiotic resistance development in zoonotic bacteria. Because of these detrimental effects, it is essential to regulate the antibiotic use in food animals. Farmers and veterinary practitioners should be aware of the problem through education by authorities. Now-adays there are good number of alternatives to antibiotics use; such as probiotics, prebiotics, herbal additives, organic acids, enzymes, active plant metabolites etc. which may boost production performance and immunity of the livestock and poultry without any adverse effect.

Big data as name implies that data that's in large as nature, is known as big data. Big data is used to describe a large volume of structure way. Big Data concern large-amount, complex, growing data sets with multiple, autonomous sources, networking, data storage, and data collection capacity, These data are rapidly expanding in all science and engineering stream, including physical, biological and medical sciences. Different companies use different technologies to maintain the big data. But now, new technologies make it possible to appreciate value from Big Data. For instance, retailers can follow user web clicks to recognize behavioral trends that develop campaigns, and stock age. Utilities can detain household energy convention levels to predict outages and to invent further efficient energy consumption. Government and still Google can distinguish and follow the emergence of bug outbreaks using social media signal. Gas and oil companies can receive the output of sensors in their drilling apparatus to make additional capable and safer drilling decisions. "Big Data" show data sets so huge and composite they are unreasonable to deal with conventional software tools. In this paper present an overview of big data's substance, variety, simple, procedure, advantages and security challenges and maintains the big data and discusses privacy concern on it.

The performance of Fingerprint Recognition is totally dependent on the Fingerprint Image Quality, because Fingerprint Recognition is the processing of Digital Image. The quality of fingerprint images influences by both environmental and scanner's surface. This paper analyzes the Fingerprint Recognition, Matching. The Minutiae-based matching technique is the best method to extract useful information about Minutiae and if the image is partial or affected by noise then the ROI can be use to optimize the result. Authentication using fingerprint has been implementing in many areas (like Attendance System, Bank Desktop Verification Login). UID is the recent project of Govt. India focused on Recognition of Identity by using Fingerprint and Retina.The conclusion state about how minutiae points are important to recognize fingerprint and ROI (the specified limited area) to avoid error within less time. Whereas, 'one to one matching' can quickly reply compare to 'one to many matching'. Future scope of "Fingerprint Recognition based on Minutiae" has wide range of application areas such as Mobile Computing, Bank ATM, NAREGA Identity Verification, etc.
