• Industry
• Transportation
• Domestic,
• Others Waste open burning Transboundary, etc.

9
Acid deposition driving forces and emissions
the situation in 2030

• Industry
• Transportation
• Others Waste open burning Transboundary, etc.

10
Acid deposition driving forces and emissions
the evidence

• Statistical data
• Projection (National monitoring network
  Research)
• (National and international)

11
Acid deposition deposition rates the situation
now

• DRY DEPOSITION
• SO2 0.20-0.60mg/m3
• NO2 0.15-0.30mg/m3
• CO 15-60mg/m3
• WET DEPOSITION
• SO42- Max. 550umol/L 30-60mmol/m2
• NO3- 40mmol/m2

12
Acid deposition deposition rates the situation
in 2030

• DRY DEPOSITION
• SO2 24391 ton/y (Indus. 16067 Trans 6362
  Domes 1962)
• NOx 58886ton/y (Indus. 10886 Trans 47550
  Domes 450)
• CO 511051 ton/y (Indus. 2812 Trans 495108

14
Acid deposition impacts the situation now

• In the North, the lowest pH value of found in Hoa
  Binh of 3.82, where is rich eco systems like
  lakes, rivers, forest that acid rain may cause
  effect on
• Magnitude of acid rain in South of Vietnam and
  its impacts on shrimp farming are one of the
  early studies

15
Acid deposition impacts the situation now

• Acid rain has appeared in the central province of
  Quang Nam over the last few days, damaging crops
  in several areas in Dien Ban District, including
  123 ha of cotton trees.
• Gas emission from more than 120 ceramic and 1100
  bricks enterprises in Vinh Long with more than
  2300 chimneys has significantly effect on the
  growth of coconut garden and some other trees
  like mango, jackfruit reduce the productivity of
  longan

16
Acid deposition impacts the situation now

• Gas emission of around 50 brick kilns in Long
  Bien Hanoi has damage on crops. The come from
  farm production (in 2000m2 field) significantly
  reduced to 300,000VND/year, in compared to
  2,000,000VND/year in 2003-2004
• Acid rain causes the productivity reduction of
  20-60 for vegetables in the field scale
  experiments.

17
Acid deposition impacts the situation now

• In Viet Tri industrial zone, Lam Thao, Phu Tho,
  the bananas gardens were affected by air
  pollution which is majority SO2 from Lam Thao
  Super phosphates factory.
• In 1997 gas emission due to factorys break down
  damaged all farms and trees in surrounding areas
  (Factory compensated 80mil.VND)
• Shrimp farmed in Binh Khanh, Can Gio was shocked
  by acid rain during two days 12-13 of May, 2003
  at high ratio, especially in improved extensive
  farming ponds.

18
Acid deposition impacts the situation in 2030

• 1. Eco system including crops/forestry
• 2. Public health (direct and indirect)
• 3. Material, infrastructure
• 4. Others
