Associations of prenatal exposure to bisphenols with BMI growth trajectories in offspring within the first two years: evidence from a birth cohort study in China.

Background: Prenatal bisphenol exposure has been reported to be associated with lower birth weight and obesity-related indicators in early childhood. These findings warrant an investigation of the relationship between prenatal bisphenol exposure and the dynamic growth of offspring. This study aimed to evaluate the relationship of maternal bisphenol concentration in urine with the body mass index (BMI) growth trajectory of children aged up to two years and to identify the critical exposure periods.

[Intra- and inter-annual variabilities of particulate organic matter in the Mirs Bay from 2000 to 2010].

Based on the data obtained from monthly cruises from 2000 to 2010, temporal and spatial distributions of the particulate organic matter (POM) in the Mirs Bay were briefly presented and discussed. The POM composition and residence time were approached by combining with the chlorophyll a (Chl-a) measurements. It has been shown that the hydrodynamics in the Mirs Bay only pose a weak impact on the POM distributions.
