Principal Component Analysis Applied to the Assessment of Metal Pollution from Urban Wastes in the Culiacán River Estuary.

This article presents information related to component analysis of the metal pollution from urban wastes in the Culiacán river which is located in the Pacific coastal plain province of Mexico. Sediment core was characterized by an almost homogeneous content of sands (90%) and rather low contents of organic carbon (OC) and carbonates (0.3- 3.0 % and 0.1-3.1%, respectively). Aluminium and lithium contents showed rather small variations, indicating that sediments accumulated within the core had a similar source.
