Abstract
In Dominican Republic exists cultive larges fields of various agricultural rubles. The largest
extensions are rice, banana and cocoa; these are located in the Cibao Valley. In the eastern,
southwestern, and a small area in the north of the country, sugar cane is cultivated. Heavy
metals are found in many of these soils that could be affecting the quality of agricultural
products or production. The levels of Cr, Ni, Zn, Cu, Cd, As, Hg and Pb, determined by
X-ray fluorescence spectroscopy, in soils collected in two cultivation areas of Rice de La
Vega and San Francisco de Macoris (SFM) have been compared with the NOAA-USEPA
Canadian Agricultural Soil and Sediment Guide (CEQGs) (SQuiRTs Table). The levels of
Cr and Ni in La Vega exceeded the threshold effects levels (TEL), and the probable effects
levels (PEL). Pb levels in the La Vega area were higher than in SFM. In general, these
metals are found in the La Vega area in higher concentrations than in SFM, exceeding PEL
and TEL.
