ENVIRONMENTAL PROBLEMS
by Karen Lab
1. Overpopulation
2. Climate change
3. Heavy metals
4. Groundwater pollution
5. Chemical element that has a relatively high density and is toxic
6. include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb).
7. The three most pollutans heavy metals are Lead, Cadmium, and Mercury.
8. In this case it is currently much lower in developing countries, consequential to poverty.
9. The simulation of climate using computer-based models.
10. The difference between the maximum and minimum temperature during a day.
11. contaminates can still reach wells and therefore households
12. This situation could have devastating effects
13. it is an extremely costly operation to remove the contaminate
14. of a species exceeds the carrying capacity of its ecological niche.
15. It can result from an increase in births
16. unsustainable biome and depletion of resources
17. Water Pollution
18. Air pollution
19. Acid deposition
20. Acid deposition is a general name for a number of phenomena, namely acid rain, acid fog and acid mist
21. Typically has a pH below 4
22. It primarily consists of two types of compounds, (H2SO4) and (HNO3).
23. The water pollution harms aquatic life
24. The death of many aquatic species
25. Bacteria, viruses, protozoa and parasitic
26. Rain can remove pollutants from air
27. Air pollutants have a negative impacts on humans, animals and plants, and on air quality.
28. sulphur oxides, nitrogen oxides, Volatile Organic Compounds
