Four studies demonstrated that NaCl spray was the primary cause of browning of Pinusresinosa Ait. along salted roads. All damaged needles had high Cl and when analyzed, high Na; the symptoms produced by spraying NaCl on forest trees appeared identical with highway symptoms; damage occurred in the spring warm-up after a winter buildup of Na and Cl; damage was greatest where use of deicing salts was greatest. Coincidence between Cl in needles and on needles indicated spray was the source of the salt. Brown needles had higher osmotic potentials (Ps) in proportion to NaCl content, but high Ps was probably incidental to damage. Still unexplained are the occasional green highway pines with high Na and Cl.

Lowbush Blueberry

The effects of deicing salt (NaCl) on buds, blossoms and yields of lowbush blueberry (Vaccinium angustifolium Ait.) were assessed over 3 yr in two commercial fields adjacent to a major Nova Scotia highway. Concentrations of road salt on exposed stems were highest next to the highway, and decreased with distance from the road. Numbers of blossoms, and subsequent fruit yields were low nearest the road, and increased with distance from the highway. Numbers of live blueberry buds and blossoms, and subsequent yields, were inversely related to concentrations of road salt on the stems. Plants under plastic shelters placed near the highway had more live buds and blossoms, as well as higher yields relative to plants exposed to deicing salt.

To maintain safety during winter, deicing salt (sodium chloride) is sprinkled over roads. Snow, mixed with highway salt, is then cleared by snowplows and usually ends up on roadsides where trees are planted. On conifers, adversely affected by deicing salt, needle shedding is accelerated. Undesirable results for the environment, caused by road maintenance chemical, are damaged vegetation, soil, polluted surface and groundwater, therefore, fauna, and people are also negatively impacted. The aim of modelling is to find a coefficient for calculating ryegrass, fescue grass and meadow‐grass length of overground part after some time, accepting that the concentration of salt in melting snow and air temperature will be the same during investgation.

ABSTRACT Intravenous infusion of isotonic magnesium chloride into young cats with a resultant mean plasma magnesium concentration of 7.7 meq./100 g protein was followed by a significant lowering of the plasma calcium concentration in 90 minutes. The rate of decrease of plasma calcium is consistent with the hypothesis that calcitonin is released by magnesium in high concentrations. There was no decrease in the plasma calcium concentration in cats of the same weight thyroparathyroidectomized 60 min before an identical magnesium chloride infusion or an infusion of isotonic sodium chloride at the same flow rate. The hypercalciuric effect of magnesium could not account for the hypocalcaemic effect of magnesium. Plasma magnesium concentration during magnesium infusion into cats with an intact thyroid-parathyroid gland complex was slightly, but not significantly higher than in acutely thyroparathyroidectomized cats.
