SCHAAF, Alejandro Alberto. Environmental impact assessment by pesticide use in the agricultural region from central province of Santa Fe, Argentina. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.6, pp.1237-1247. ISSN 2007-0934.

This paper discloses a methodology to calculate the environmental impact that pesticides cause in the environment taking into account various factors. The study area was the central region of the province of Santa Fe, in the town of San Vicente, Argentina. A formula called VIA= (ET total + TH total + CA total) x 10 was formulated. Each item has its meaning, corresponding valuation and subdivision, where the different characteristics of classification are: ecotoxicology (ET), human toxicity (TH) and environmental behavior (CA). The sum of the numerical values were included in the following categories: low - medium - high - very high, which allowed us to assess each pesticide separately. The results show that most of the pesticides used are middle toxicity (43.75%), followed by low and high toxicity (21.88%) and finally the very high toxicity (12.5%). This is a pilot study where a new tool was implemented that may be subject to changes and improvements.

Palavras-chave : chemicals; environmental monitoring; toxicity.
