The effect of environmental contaminants on health is a major concern because over the last two decades, several studies worldwide have shown how chemicals present in our environment can profoundly affect the etiology of some chronic diseases. Indeed, pesticides toxicity has been clearly demonstrated to alter neurological functions and numerous epidemiological studies have shown a relationship between pesticides exposure and the etiology of Parkinsons disease (PD). However, epidemiological results are inconclusive because there is considerable heterogeneity in results likely due to statistical analysis, methodological differences, study design, control selection, differences in exposure assessment methods and diagnosis of patients.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
