An environmental health specialist or environmental health technician is a professional having proper academic training and education and credentials to investigate, test, analyze, and evaluate hazardous air, water and substance wastes in different environmental media and situations; identify potential threats to health; and recommend and implement protective measures that control hazards to human health through elimination or avoidance of those risks. These professionals have a wide range of duties including evaluating the effects of exposure to hazardous substances on humans; developing methods for controlling and reducing hazardous wastes; identifying and addressing environmental issues that threaten human health; and counseling people exposed to hazardous substances. Other duties may include occupational health, cancer prevention and treatment, safety, occupational exposure, and damage cleanup.
Environmental issues are categorized into two main areas: environmental quality and environmental toxicology. The quality of an environment refers to its safe storage, transport, use, maintenance, distribution, regulation and disposal of the products within it. On the other hand, environmental toxicology describes the adverse effects of an environment on humans and animals. The most recent environmental toxicology reports on global warming, climate change, and ecosystem pollution continue to assert the importance and necessity for urgent actions to be taken to conserve the earth’s ecosystems and prevent climate change. The effects of climate change include extinctions of species, rapid climate changes, disruption of eco-systems, and increasing human conflicts over resources.
A new approach to environmental monitoring and evaluation is the concept of ecological units. These are the natural systems which interactions among living organisms and their systems dominate to create a self-sustaining ecological balance. Interactions among living organisms and their systems encompass the earth, human societies and their environments, and nature in general. There are five eco-systems namely food webs, biogeochemical cycles, ecological communities, the built environment, and the human ecology. Each of these eco-systems is dynamic but in equilibrium within the overall environment.
The food web consists of all the plants and animals which are part of our ecosystems. This web is composed of many different types of plants and animals and their life cycles and relationships with one another. Bioresigns of the food web are used as indicators for conservation and management of the natural environment. The natural resources comprise the air, land and water which together provide an important part of the Earth’s inventory of natural resources. These resources are also essential for human health and survival.
The biogeochemical cycle is the process by which the earth stores energy from the sun in the form of plant food and in the oceans for the greening of the world. The human environment is intimately connected with the natural environments because all human activities have some impact on the earth’s biogeochemical cycles and therefore on the earth’s environment. The built environment refers to the infrastructure which surrounds and protects the natural habitats of the planet. It can be broadly categorized into the following structures: the physical structure of the planet (including the ozone layer, the atmosphere, the ionosphere and the cryosphere), the biogeochemical cycles, the physical structure of the terrestrial system and the life diversity.
Global warming is one of the most prominent environmental issues around the globe today. This article looks at the main article on global warming and its possible solutions. There are many theories about the cause of global warming. Some of these theories include the greenhouse gases, solar radiation and the nuclear weapons. But the main article is concerned with the greenhouse gases.
Every living thing needs an environment favorable for its survival. However, changing the environmental conditions can prove to be disastrous for many organisms. A neha doctor is required to assess and to prescribe remedial measures to help mitigate any such changes or deterioration. This can be achieved in a variety of ways including modification of lifestyle, improving the efficiency of energy use, recycling waste and other greening practices. An environmental health professional can also help create awareness about the need for these modifications.
The health of an environment is dependent on the physical condition and the existence of living organisms within it. The analysis of these living organisms determine the overall health of the environment. An effective regulation of the population level, the acidity or alkalinity of the environment is important. With industrialization, the number of factory emissions has increased dramatically. This has significantly affected the environment. Carbon dioxide in particular has become a very powerful greenhouse gas.
