Other toxic substances found in almost all of the dust samples include chemicals known as phthalates that are often found in vinyl flooring, food packaging, personal care products and have been linked to developmental problems in babies, hormone disruption, and are also thought to affect the reproductive system.
Pesticides have been linked to developmental problems in children, and may act as carcinogens or throw off the endocrine system, according to the U.S. Environmental Protection Agency.
#Hawaii will become the first state in the country to #BanChlorpyrifos - a chemical that has been linked to developmental delays and learning disabilities in children.
Furthermore, bats are also one of only a few groups of vertebrates to exhibit vocal learning [27], [28], a condition that might be a precursor to language, and the evolution of which has been linked to developmental and seasonal patterns of FoxP2 expression in the brains (area X) of some songbirds [9].
In addition to these environmental factors, developmental stability is also influenced by intrinsic genetic characteristics: the loss of genetic diversity has a significant effect upon the occurrence of scale anomalies in the dice snake, Natrix tessellata [10], and high homozygosity has been linked to developmental anomalies [8].
"By cutting emissions that are linked to developmental disorders and respiratory illnesses like asthma, these standards represent a major victory for clean air and public health - and especially for the health of our children," Ms. Jackson said in statement.
Carbamate pesticides were linked to developmental delay but not ASDs.
Symmetry is linked to developmental stability [16].
Similarly, the formation of a functional zygotic nucleus following fertilization, and the subsequent development from a one-cell to an eight-cell embryo, also requires extensive alterations in chromatin structure that may be linked to developmental potential.
