Phthalate diesters have been shown to be developmental and reproductive toxicants in animal studies. A recent epidemiologic study showed certain phthalates to be significantly associated with reduced anogenital distance in human male infants, the first evidence of subtle developmental effects in human male infants exposed prenatally to phthalates. We used two previously published methods to estimate the daily phthalate exposures for the four phthalates whose urinary metabolites were statistically significantly associated with developmental effects in the 214 mother-infant pairs [di-n-butyl phthalate (DnBP) , diethyl phthalate (DEP) , butylbenzyl phthalate (BBzP) , diisobutyl phthalate (DiBP) ] and for another important phthalate [di-2-ethylhexyl phthalate (DEHP) ]. We estimated the median and 95th percentile of daily exposures to DBP to be 0.99 and 2.68 microg/kg/day, respectively ; for DEP, 6.64 and 112.3 microg/kg/day ; for BBzP, 0.50 and 2.47 microg/kg/day ; and for DEHP, 1.32 and 9.32 microg/kg/day. The U.S. Environmental Protection Agency (EPA) reference doses for these chemicals are 100 (DBP) , 800 (DEP) , 200 (BBzP) , and 20 (DEHP) microg/kg/day. The median and 95th percentile exposure estimates for the phthalates associated with reduced anogenital distance in the study population are substantially lower than current U.S. EPA reference doses for these chemicals and could be informative to any updates of the hazard assessments and risk assessments for these chemicals.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 24. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 September 2020.
All research outputs
#1,923,842
of 33,059,767 outputs
Outputs from Environmental Health Perspectives
#1,632
of 9,999 outputs
Outputs of similar age
#5,366
of 223,353 outputs
Outputs of similar age from Environmental Health Perspectives
#18
of 95 outputs
Altmetric has tracked 33,059,767 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 94th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 9,999 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 27.6. This one has done well, scoring higher than 83% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 223,353 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 97% of its contemporaries.
We're also able to compare this research output to 95 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 81% of its contemporaries.
