[Ca.sup.2+] and [Mg.sup.2+], regarded as two kinds of main crustal-related ions, occupied together 32.5% of total ionic equivalents, indicating that crustal-derived elements had key contribution to the neutralization of the
acid precipitation. Nss-S[O.sub.4.sup.2-] and nss-[Ca.sup.2+] accounted for 96.1% and 98.5% of the total sulfate and total calcium, respectively.

When

Effects of
acid precipitation on embryonic mortality of Ambystoma maculatum.
With hindsight, Keller notes, heightened Congressional concern on this issue pre-dated his remarks even though the issue was not yet "institutionalized" (i.e., embedded in policy maker-scientist discourse) the way
acid precipitation was.
The wide use of acrylic clearcoats led to a new problem, noticeable etch damage due to
acid precipitation (rain, fog, or dew), particularly on new or nearly new vehicles.
On the other hand, our activities are contributing an ever-growing proportion of the total amount of
acid precipitation. In addition, some transfer of acid from the atmosphere to ground level occurs without the help of precipitation.
They are vulnerable to invasive species, pollution, and other threats attributed to global climate change, such as changes in precipitation, drought, increased UVB radiation, and
acid precipitation. However, loss of wetland habitat is the largest contributor to amphibian declines throughout the United States.
The past management of
acid precipitation and smog show that scrubbing technology is always a last-resort option.
From "
acid precipitation" to "zionism", the approximately 800 entries of this three-volume encyclopedia, ranging in length from 500 to 5000 words each, seek to provide understanding of the history, economic development, and politics of the developing world from 1945 to the present day.
Acid precipitation, largely from fossil fuel burning emissions, is killing thousand of lakes as well.
Approximately 20 mL of the supernatant from the caprylic
acid precipitation was fractionated at 4 [degrees]C with stepwise addition of 100% saturated ammonium sulfate to give 20%, 30%, 40%, 50%, or 60% saturation.
