THE IMPACT OF SOIL POLLUTION ON HUMAN HEALTH AND THE ENVIRONMENT

Abstract

The study of soil pollution has occupied the attention of a large number of researchers because of its continuity and effect on humans, animals and plants alike. Soil pollution occurs as a result of the entry of elements that change the composition and organism of the soil, and reduce its fertility, making it more vulnerable to drought, and unsuitable for agriculture. This study proposes an index system for evaluating the inherent risk level of polluting factories and introduces an integrated risk assessment method based on human health risk. This study will discuss the scientific and technical issues analysts should consider regarding the use of these methods to estimate the burden of disease attributable to outdoor fine particulate pollution in their own settings. Most of the agricultural lands are irrigated by rivers polluted with factory wastewater. Also, the research discusses the most important sources of pollution represented by pesticides and chemical fertilizers that contain toxic substances and seep into the soil to remain for a long time, and contribute to eliminate soil fertility. The research deals with the impact of logging the desertification of agricultural areas and their transformation into a vast desert that is unsuitable for agriculture, and pollutes the soil with hydrocarbons. Attention was drawn to the problem of existing inequalities in the global burden between economies with different income levels.
KEYWORDS : soil pollution, environmental factors, rivers polluted, factory wastewater, soil fertility, wastewater, human health risk.

A STUDY ON DEVELOPMENT OF A BIOMETRIC AUTHENTICATION SYSTEM

Abstract

This study covers the field of biometric systems focus on biometric authentication systems. A short and general overview of biometric authentication systems gives some insight in how the various biometric data can be used for authentication. The problems of varying biometric data, caused by noise respectively human nature and approaches to solve these problems with multi-biometric systems in combination with information fusion, are also discussed. Since there is such a vast range of variances for the usage of biometric systems, some type of statistics is determined. Biometrics is the measurement of biological data. The term biometrics is commonly used today to refer to the authentication of a person by analyzing physical characteristics, such as fingerprints, or behavioral characteristics, such as signatures. Since many physical and behavioral characteristics are unique to an individual, biometrics provides a more reliable system of authentication than ID cards, keys, passwords, or other traditional systems. The word biometrics comes from two Greek words and means life measure. To provide a comprehensive survey, we not only categorize existing biometric techniques but also present detailed of representative methods within each category. Physical characteristics commonly used in biometric authentication include face, fingerprints, handprints, eyes, and voice. Another program compares this pattern with the one representing the user that was recorded earlier and stored in the system database.
KEYWORDS : Biometric authentication, biometric systems, fingerprints, handprints, eyes, and voice, computer networks, database, ID cards, keys, passwords.
