Both BPA and phthalic acid esters are well known to possess oestrogenic activity albeit be it weak and have the potential for endocrine disruption due to their ability to interact with endogenous oestrogen hormone receptors.
aegypti showed potential larvicidal property which might be due to the presence of various phytochemical constituents such as propanoic acid, butanoic acid, benzene acetic acid, 4-(1,1-dimethylethyl)-methyl ester, phthalic acid, hexadecanoic acid, 1,2-benzendicarboxylic acid and 9-octadecenamide which may cause degeneration of the pupal alterations in the respiratory system of mosquito larvae, and reproductive system (28-29, 31).
phthalates metabolites, are determined because the level of monoesters is higher than the level of diesters of phthalic acid, and the contamination of the sample by ubiquitous diesters during the collection, storage and analysis itself is avoided [18].

The primary complex, metal phthalate was prepared by mixing of suspension of phthalic acid (1.66g-0.01mole) in water with sodium bicarbonate to obtain neutral solution.
The chemical structure of phthalic acid (or phthalates) is nearly identical to quinolinic acid.
Several studies of phthalic acid esters (phthalates) used as plasticizers in numerous consumer products and building materials reveal phthalate exposure among residents in industrialized countries.
