The Influence of Calcium Chloride on Soil Animals, Microorganisms, and Phytoplankton

Calcium chloride (CaCl2) is an inorganic chemical from the group, and it widely used as one of snow removal agents on road in winter. Laboratory experiments were conducted to examine effects salt (NaCl) soil organisms (a animal, microorganisms, plankton). The dwelling Armadillidium vulgare died high concentration calcium treatment. longer processing time A. at chloride, lower survival rate. 16% a 1 mM. In disc diffusion test, diameter inhibition zone proportionally increased with chloride. Micrococcus sp. was slightly higher inhibitory activity than those three microorganisms (Bacillus subtillus, Pseudomonas flurescens, Xanthomonas maltophilia). About 90% (phytoplanktons) when 15.0 mM solution used. this study, concentrations affected animals, water microorganisms. If dissolves flows into rivers or lakes, can cause destruction aquatic ecosystems threat small organisms.
