Research methods in the public and environmental health

When we are talking about Health Ecology, we must first emphasize that it is science that in its methodological approaches and methods encompasses professional and scientific research focused on certain aspects of human health, including quality of life, determined by the interaction of physical, chemical, biological and social factors in the environment. It also refers to the theory and practice of assessing, correcting, controlling and preventing environmental factors that may affect the health of the present and more importantly to emphasize future generations. In its complexity, health ecology is a multidisciplinary science that encompasses a wide range of professional and scientific co- operation with many physical and natural sciences. It should be emphasized that there are basic three objectives in approaching the use of many methods in health-ecological researches, primarily scientific where our aim is to gather the knowledge of destiny and the effects of polluting into the biosphere, then the technology in which we need to develop and apply methods to better understand the fate and effects of polluting the biosphere and practical in which the results of all our methods and procedures must be used for the practical application of acquired knowledge and procedures to solve a particular environmental problem. Modern professional and scientific research in which teams of experts in the sanitary profession work with their knowledge and experience, focusing on discovering changes in the human body at very low levels of biological integration such as biomolecules. This level of biological integration sufficiently early suggests the possibility of developing irreversible molecular changes on our molecules as a result of some of the environmental factors. So we can say that the main objective of public health research and environmental health research in the future is to detect changes to the lower levels of biological integration, so that all public health preventative actions based on such research will in time prevent the adverse effects on human health and the possibility of developing a diseases.
