SAND (1993), Pb is the most toxic element of the heavy metals. It is established that the consumption of Pb containing wine (150 mg/l) and beer leads to increase of its amount in blood (SHERLOCK et al., 1986). FAO/WHO (1972) recommends for the Pb content in the daily meals and drinks of people not to exceed 0.43 mg.
The air of India in the winter season was polluted with Pb at 1 μg m-3, which is many folds higher than the limit. The acceptance rate of metal absorbing types in soil and plants is supported by independent biological factors or in arrangement with geochemical factors. ... Zn, and Fe can trigger Pb absorption. There are some specific types of ...
One financial valuation statistic used to compare the current market value of a company to its book value is the Price to Book Ratio (also known as Market to Book Ratio). The book value is equal to the company's net assets and is derived from the balance sheet. In other words, the ratio is used to compare a company's available net assets to …
