Examples

1. ‘They are immediately downwind of coal-burning electric plants in the Ohio and Tennessee valleys
2. and their high elevation makes them extremely susceptible to sulfates and nitrates moving through the atmosphere.’
3. ‘It occurs in all kinds of minerals
4. such as oxides
5. carbonates
6. nitrates
7. sulfates
8. and phosphates.’
9. ‘The technique can identify iron-bearing phases (such as oxides
10. silicates
11. sulfides
12. and carbonates)
13. as well as the amount of iron in each phase and the presence of iron in various oxidation states.’
14. ‘Biodiesel reduces emissions of unburned hydrocarbons
15. carbon monoxide
16. polycyclic aromatic hydrocarbons
17. nitrated polycyclic aromatic hydrocarbons and particulates.’
18. ‘The respirable portion of particulates can include acid condensates
19. and organic compounds.’
20. ‘Inorganic anions such as chloride
21. nitrate and sulphate can be separated in about five minutes.’
22. ‘Herbicides include a wide range of compounds
23. such as common salt
24. and ammonium and potassium salts.’
25. ‘Common among these are bicarbonates
26. calcium
27. chlorides
28. fluorides
29. magnesium and sulfates - all of which can cause salt stress if found in excessive amounts.’
30. ‘The Podolia ash beds consist largely of clay minerals accompanied by a variety of primary volcanogenic crystals and secondary sulphides
31. sulphates
32. oxides
33. and silicates.’
34. ‘Tiny particles of soot or chemical compounds like sulphates reflect sunlight and they also promote the formation of bigger
35. longer lasting clouds.’
36. ‘The magnesium corrosion control rod present in many hot water heaters can chemically reduce naturally occurring sulfates to hydrogen sulfide.’
37. ‘Other contaminants include arsenic
38. chromium
39. cyanides
40. phenols
41. gases and ‘combustible materials’.’
42. ‘Black smokers
43. debouching fluids at 350°C into the overlying sea water sit atop a mound of hydrothermal minerals
44. including sulphides
45. and silicates.’
46. ‘The oils are first reacted with sulfuric acid
47. which converts them into sulfates.’
48. ‘Leachate typically contains organic compounds together with metal chlorides and sulphates
49. and has a high chemical oxygen demand due to the presence of reducing species.’
50. ‘These minerals can be supplemented in the diet as inorganic oxides
51. or organic chelates with the mineral bound to an amino acid or peptide complex.’
52. ‘They have a somewhat chalky flavor
53. which is indicative of sulfates
54. but rules out regular sodium chloride.’
55. ‘Comprised primarily of soot
56. fly ash
57. and organic particles
