چکیده
Paris green or Schweinfurt's green is a cheniical compound of arsenic, copper and acetic acidIts chemical name is copper aceto-arsenite, its f?r" mula being 3 Cu H As 03 -jCu (C2 H3 Os)r It is therefore a double salt of copper arsenite and acetate. It is a microcrystalline powder 01 emerald green colour. It is practically insoluble in water. It is perfectly soluble in ammonia a11 concentrated acids. In the pure state it contain5 58.6 per cent, of arsenious anhydride (As2 O*)' Paris green is often adulterated. The percentage content of arsenious anhydride should thereto1^ be ascertained from the dealer when ordering

Frequent use of synthetic larvicides has led to the development of resistance in many species of mosquitoes as well as risk of environmental pollution. Recently, encapsulating essential oils (EOs) in surfactants or polymers is being employed as an approach to control the volatility of EOs as green larvicides. In this research, components of tarragon (Artemisia dracunculus) essential oil were id...
