The association between maternal exposure to organophosphate pesticides and neonatal anthropometric measures: A systematic review and meta-analysis.

Background: This study aimed to evaluate the epidemiological studies on the relationship between organophosphate (OP) pesticide exposure during pregnancy and neonatal anthropometric measures.

Materials And Methods: In this systematic review and meta analyses, a comprehensive search of the literature for the association of maternal exposure to OP pesticides and birth outcome including birth weight, birth length, and head circumference was conducted from scientific databases of MEDLINE, Scopus, Web of Science, and Cochrane library until the end of April 2019. We used the following keyword to identify the relevant studies: "birth weight," "birth length," "pregnancy outcome,""birth outcome," "organophosphate pesticides," and "organophosphate metabolites.

Data on the trend of corrosivity and scale formation potential of Shiraz groundwater drinking water resources during 2001-2007.

The aim of this study was to evaluate the corrosivity and scale formation potential of groundwater drinking water resources for the time period of 2001 to 2007 in Shiraz, Iran. Chemical parameters including total alkalinity, EC, pH, temperature, and TDS of ground water resources were analyzed. Langelier saturation indices (LSI) and Ryznar stability indices (RSI) were utilized to determine the potential for corrosivity and scale formation.
