Water Hardness

The paper presents a comparative study of the toxicity of chromium and molybdenum, carried out in hard aquarium 0,14⁰Clark and soft natural 8,2⁰Clark waters. A decrease in water hardness leads to an increase in the acute toxicity of metals, which is expressed in a decrease in the values of semi-lethal concentrations by 3 times for molybdenum and 25 times for chromium.The results obtained show that the toxicity of metals can differ significantly in waters with different hydrochemical compositions. The data presented in the work can be used in the development of regional MPC standards.

The introduction reviews the historiographic problem of the relation between fire sacrifice (yajña) and image worship (pūjā), which have traditionally been seen as opposing ritual structures serving to undergird the distinction of “Vedic” and “Hindu.” Against such an icono- and theocentric approach, it proposes a history of the priesthood in relation to royal power, centering on the relationship between the royal chaplain (purohita) and astrologer (sāṃvatsara) as a crucial, unexplored development in early Indian religion. In order to capture these historical developments, it outlines a method for the comparative study of ritual forms over time.
