Synergetic effects with other anthropogenic pollutants

SYNERGETIC EFFECTS WITH OTHER ANTHROPOGENIC POLLUTANTS 

As we have discussed in Chapter 4, acid rains are of great environmental concern in the Southeast Asian sub-region and the pH of rainwater drops often below 4.5 in many countries of question. Over the last 10 years, a number of authors have suggested that forest fires in the tropics may have an acidifying effect on rainwater with potential consequences to tropical ecosystems (see, for instance, Levine J. S., Global Biomass Burning, 1991, in the list of further reading). 

Biomass fires are inversely related to precipitation they generally occur during dry seasons when the precipitation amounts are very lowornon-existent since heavy rains tend to put the fires out. Therefore, one would anticipate that even if the acidity 

Here we will consider the appearance of synergetic effects of acid rain and haze in some places of Southeast Asia. The example will be shown from a case study in Brunei Darussalam (Radojevic and Tan, 2000). 

The Volume Weighted Mean (VWM) pH of rainfall determined during periods unaffected by biomass fires and baze is shown as a line for comparison. The data does
