Soil acidification can be the result of acid rain. But overuse of certain types of nitrogen fertilizer is another cause, and this is what the researchers identify as the culprit in China.
Experiments that add iron to the sea have had mixed success, though, and may cause harmful algal blooms and ocean acidification.
If acidification kills tiny sea snails known as pteropods, as it is likely to, the Pacific salmon that feed upon these planktonic creatures may also die.
Methods After culture solution acidification, acetic acid was extracted by acetone and ether, and detected by gas chromatography.
木荷凋落物可通过增加土壤有机质 ,提高土壤和下渗液的盐基量 ,提高土壤pH值 ,降低土壤水解性总酸度等途径来缓解土壤的酸化作用
and the litter of S.supercan relieve the soil acidification effect the ways of increasing the soil organic matter,raising the salt base content of soil and infiltration liquid,enhancing the soil pH value,and reducing the total acidity of soil hydrolysis.
Application of Grey System Theory in the Prediction of Soil Acidification.
In the treatment of antibiotic wastewater, hydrolysis acidification-SBR-contact oxidation process can used to replace anaerobic digestion process for improving water quality and treatment efficiency of subsequent aerobic biochemical process, avoiding secondary pollution from sulfur-containing methane which was produced from anaerobic digestion.
The integrated hydrolytic acidification-biological aerobic filter was used to treat oil-refining wastewater.
Due to acidification the agar surrounding the colonies may become yellow.
Treatment of dyeing wastewater by hydrolytic acidification, bio contact oxidation and flotation process was described.
