Abstract

This contribution is focused on worldwide commonly used synthetic musk compounds and their occurrence in water biota, specifically in fish muscle. Method of maximum likelihood considering doubly left-censored samples is used for statistical evaluation of musk compound concentration. As for model distributions, the exponential and Weibull distributions are considered. Moreover, using the asymptotic properties of maximum likelihood estimates, concentrations of musk compounds extracted from the fish samples caught in front of and behind a wastewater treatment plant are compared.

Keywords

Musk compounds, maximum likelihood, doubly left-censored sample, Weibull distribution, exponential distribution, Lagrange multiplier test
