Environmental compartments and health risk assessment
In order to deal with the diversity of natural systems, we think that they are composed of compartments. These are defined as part of the physical environment, defined by spatial boundaries, which distinguish them from the rest of the world, such as the atmosphere, soil, surface water, and even biota.
When a chemical is released into the environment, it is distributed into four main environmental compartments: (1) air, (2) water, (3) soil, and (4) flora and fauna, that is, living things. The four main routes of entry are inhalation, ingestion, injection, and absorption through the skin and eyes. The main types of pollution include: air, water, soil, light and noise. Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites. The variety of environmental pressures that have been shown to cause greater asymmetry may not be unique. Many other types of stress can have similar effects.
Environmental receptors refer to natural areas, such as national or state parks, forests, or monuments; officially designated sanctuaries, sanctuaries, refuges or wildlife areas; and federal wilderness areas, which can be exposed to toxic concentrations and radiation at any time. or equal to. Pollution can cause littering of the landscape, poison the soil and waterways, or kill plants and animals. For example, long-term exposure to air pollution can lead to chronic respiratory diseases, lung cancer and other diseases. The accumulation of toxic chemicals in top predators can make certain species unsafe for consumption.
The health risk assessment includes questionnaires, health status assessments, and personalized feedback on actions that can be taken to reduce risks, maintain health, and prevent disease. Risk assessment has four steps: hazard identification, exposure assessment, dose response assessment and risk characterization.
