“…PCA has been used extensively for various applications related to water quality. As examples, Wunderlin et al (2001) used PCA for the evaluation of spatial and temporal variations in river water quality and Marengo et al (1995) to characterise water collected from a lagoon as a function of seasonality and sampling site and for the identification of significant discriminatory factors. Hamers et al (2003) employed PCA to study pesticide composition and toxic potency of the mix of pollutants in rainwater and Librando et al (1995), for the analysis of micropollutants in marine waters.…”

“…4), 1-r Pearson distance was used. All data were initially standardized through z-score transformation (Marengo et al 1995), and then statistical and mathematical calculations were performed using version 8.0 of the Statistica software (StatSoft Inc., Cracow, Poland) and Microsoft Office Excel 2003 spreadsheet (Microsoft Corporation, Warsaw, Poland). For dendrograms shown in Fig.…”

“…Samples collected from one watercourse can be grouped into two-clean and polluted, or three-clean, highly and medium polluted clusters representing similar water properties (Brogueira and Cabeçadas 2006;Chang 2005;Kannel et al 2007;Reghunath et al 2002). Marengo et al (1995) mentions application of CA for samples from Lagoon of Venice collected from various sites and at different seasons of the year. In this instance, it was concluded that location of sampling point rather than a season of sample collection determines clustering of the results.…”

“…La dependencia estacional de la composición de aniones inorgánicos del agua de la laguna de Venecia fue investigada por Marengo et al (1995) a lo largo del periodo junio-noviembre de 1993. Desafortunadamente en este periodo el clima se comportó de forma atípica en lo que concierne tanto en lluvias como en temperatura y los datos obtenidos para las variables consideradas no permitieron correlacionarlas directamente con la temporada.…”

“…El PCA se usa como un procedimiento matemático que transforma un conjunto de variables correlacionadas en un nuevo conjunto de variables no correlacionadas (las componentes principales) (Johnson, 1992). Esta técnica está siendo cada vez más popular en la modelación ecológica y ambiental (Marengo et al, 1995;Vega et al, 1998;Wunderlin et al, 2000;Petersen et al, 2001;Brodnjak-Vončina et al, 2002;Simeonov et al, 2002;Montes-Botella et al, 2003;Mendiguchía et al, 2004;Singh et al, 2004;De Carlo et al, 2004;Parinet et al, 2004;Çamdevýren et al, 2005;Singh et al, 2005;Giussani et al, 2006;Kowalkowski et al, 2006;Terrado et al, 2006;Castañé et al, 2006;Felipe-Sotelo, 2007;Terrado et al, 2007;Shrestha et al, 2007;Kannel et al, 2007).…”
