Pharmacological Evaluation of Hydroalcoholic Extract of Herbal Drugs for Its Antidepressant Potential

The recent emergence of heavy metal poisoning of soil into limelight has been categorized as a critical environmental issue due to the persistence, toxicity, and possible effect on human health and environmental stability. In an attempt to know more about the near-control variables that mediate the behavior of contamination and its causation, hence, this paper quantitatively establishes the relationshipbetween the levels of heavymetal andimportant soil physico-chemical attributes. The atomic absorption spectroscopy (AAS) and inductively coupled plasma mass spectrometry (ICP-MS) were used to determine the amount of lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), and nickel (Ni) by analyzing the soil samples collected in the polluted areas. We also tested the pH of the soil, the percentage of the organic matter, and the soil texture. The results demonstrated that there is a negative significant correlation between the pH and the metal concentration with a high negative value showing an upward progress in the mobility of the metal in the acid environment, and organic matter and clay content is positively correlated and it insinuates that they help in the adsorption and stabilization of the metal. These findings demonstrate the relevance of soil chemical and physical properties as factors shaping the conduct of heavy metals and incorporating them as key factors in the design of successful cleanup and management protocols of soils
