EESA10H3 Lecture Notes - Lecture 1: Passive Smoking, Environmental Health, Environmental Factor
Document Summary
Environment is everything that affects a living organism: air, water, soil, biota, manmade environment. Human health and environment health are linked: environmental hazards come because of air, water or soil pollution, loss of biota, and manmade environment (environment we create) Models of gene-environment interaction: genetic makeup increases exposure to an environment risk factor, genetic makeup increases susceptibility to an environmental risk. Health factor: genetic makeup and environmental factor are independent risk factors. Environmental health comprises those aspects of human health, disease and injuries that are determined or influenced by factors in the environment. This includes the direct and indirect pathological effects of: chemical, biological, physical (only man-made) Chemical hazards: housing, urban development, land use, transportation, e. g. pesticides, chemicals in air, water, soil, food. Biological hazards: bacteria, viruses, parasites, allergens, animals such as bees, e. g. malaria carried by mosquitoes tend to be carried by biota living things that can impact human health.
