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.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
