Title

TRENDS OF AMPHETAMINE TYPE STIMULANTS DTR MASS LOAD IN POZNAN BASED ON WASTEWATER ANALYSIS

Pages

  610-620

Abstract

 Background: The aim of this study was to determine the monthly DTR mass load of amphetamine-type compounds in Poland as well as an investigation of cyclical behaviour by using TIME SERIES analysis and especially trends analysis.Methods: Amphetamine, methamphetamine and MDMA (ecstasy) were detected in WASTEWATER samples collected from the main WASTEWATER Treatment Plant in the city of Poznan using liquid chromatography/tandem mass spectrometry (LC-MS-MS). Back-calculations used in the sewage epidemiology approach were applied to estimate the DTR mass load level of the drugs analyzed. Trends analysis was performed by fitting the data to a simple linear regression and then by using smoothing by means of a moving average (Mat lab 2013a). Trend analysis displays a steady tendency of increase or decrease throughout TIME SERIES. When we plot the observation against time, we may notice that a straight line can describe the increase or decrease in the series as time goes on. Simple linear regression and method of last squares to estimate parameters of a straight-line model were used. Additionally, a lagged plot (autocorrelation plot) was used to investigate an appearance of correlation between AMPHETAMINES throughout time.Results: Trends analysis showed the slight increase in consumption of amphetamine and decreasing trend in case of ecstasy and methamphetamine within the investigated period. There is also visible, strong correlation between ecstasy and methamphetamine consumption which cannot be stated in case of amphetamine.Conclusion: Trends analysis is a very useful tool to analyse the increasing or decreasing tendency in consumption of ILLICIT DRUGS based on the DTR mass load data.
