identify and describe 3 environmental health hazards that cause ill health,crises,and or disasters within your community or any other community within south africa and globally.
Environmental factors: air pollution with carbon monoxide, carbon dioxide, nitrtic ans sulphuric acid fumes, methane, particulate pollutants
Water pollution: sewage and sullage outflow, inadequate effluent treatment, disposal of city garbade into rivers, fertilizers, pestisides, excreta disposal, washing of cattle in river water.
Human factors: Age: young have higher accident rates.
Ergonomic workplaces reduce accidents
Addition to alcohol and smoking
drug abuse!
That's the most I know hope it helped... at least a-little.
To identify and describe three environmental health hazards that cause ill health, crises, and/or disasters within a community in South Africa or globally, we can follow a step-by-step process.
1. Research: Start by researching environmental health hazards in South Africa or any other community globally. Look for reliable sources such as government reports, scientific studies, and reputable organizations like the World Health Organization (WHO), the Environmental Protection Agency (EPA), or local health departments.
2. Analyze: Once you have gathered the information, analyze it to identify the hazards that commonly cause ill health, crises, or disasters. Consider both natural and human-made hazards impacting the environment.
3. Select Three Hazards: Finally, choose three environmental health hazards based on their significance, prevalence, severity of health impacts, and relevance to your community. Describe each hazard, its impact on health, and potential crises or disasters it can cause.
Keep in mind that the specific hazards may vary based on the area and timeframe you are examining. However, here are three common environmental health hazards that can affect communities in South Africa or globally:
1. Air Pollution:
Description: Poor air quality caused by industrial emissions, vehicle exhaust, indoor cooking or heating fuels, and natural sources like dust and wildfires.
Impact on Health: Air pollution can cause respiratory diseases (such as asthma and bronchitis), cardiovascular problems, and even premature death.
Crises or Disasters: Excessive smog or pollution episodes can lead to public health emergencies, reduce visibility, and disrupt daily activities.
2. Water Contamination:
Description: Contamination of water sources (rivers, lakes, groundwater) due to industrial waste, agricultural runoff, inadequate wastewater treatment, or improper sanitation.
Impact on Health: Drinking contaminated water or coming into contact with it can lead to waterborne diseases like diarrhea, cholera, dysentery, and other gastrointestinal infections.
Crises or Disasters: Water contamination can cause outbreaks of diseases, including emergencies like cholera epidemics or water shortages during disasters.
3. Climate Change:
Description: Long-term changes in weather patterns caused by greenhouse gas emissions, leading to rising temperatures, extreme weather events, sea-level rise, and shifts in ecosystems.
Impact on Health: Climate change can increase heat-related illnesses, worsen air pollution, promote the spread of vector-borne diseases (such as malaria or dengue fever), and disrupt food and water systems.
Crises or Disasters: Climate change can result in natural disasters like hurricanes, floods, and droughts, leading to displacement, destruction of infrastructure, and an increased burden on healthcare systems.
Remember, conducting your research using up-to-date and accurate information will provide a more comprehensive and relevant understanding of the environmental health hazards in your chosen community.
