"Sugar maple appears uniquely sensitive to
acid rain and calcium depletion.
"Walking in
acid rain, or even swimming in a lake affected by
acid rain, is no more dangerous to humans than walking in normal rain or swimming in non-acidic lakes," environment protection agency said, (https://edition.cnn.com/2018/05/09/us/hawaii-kilauea-volcano-acid-rain/index.html) CNN reports.
Rain becomes
acid rain when its pH drops to 5.0 or below, the CNA reported.
With regard to fresh bodies of water,
acid rain can also increase the alkalinity of lakes, rivers and even those dedicated to aquaculture, she said.
The researchers find a greater level of particulate air pollution and associated premature mortality under the
Acid Rain Program than under a hypothetical no-trade scenario in which units emitted SO2 at a rate equal to 2002 allowance allocations plus observed drawdowns of their allowance banks.
The western slope of its mountains catches both dry pollution and
acid rain from the industrial Midwest.
Acid rain is a broad term referring to rain, snow, sleet, hail, fog, and deposits of particles and gases from the atmosphere.
According to the study, concentrated sulphuric
acid rains and intense ocean acidification by SO3-rich impact vapors resulted in severe damage to the global ecosystem and were probably responsible for the extinction of many species.
The ecological effects of
acid rain are most visible in the aquatic environments, such as streams, marshes and lakes.
Acid rain, we were told, would decimate our woodland trees but didn't and global warming, which promised us a Mediterranean climate, didn't either so these phrases were abandoned by our clever environmentalists in favour of climate change which is flexible and can explain any change in our weather.
The paper cited another health official, Mohammad Alavi, as saying
acid rain may have caused symptoms such as shortness of breath among those admitted to hospitals.
'It's generally accepted that
acid rain harms trees, but the value of our study is that it proves the causal link between the chronic loss of soil calcium caused by decades of acid ram and its impact on tree growth,' said John Battles of UC Berkeley, who led the study.
