Reproductive toxicity in boron exposed workers in Bandirma, Turkey.

I did come across two articles from Thammasat University that I wanted to get your feedback on:
Effect of borax on immune cell proliferation and sister chromatid exchange in human chromosomes
www.ncbi.nlm.nih.gov/pmc/articles/PMC2776007/
Genotoxic effects of borax on cultured lymphocytes.
www.ncbi.nlm.nih.gov/pubmed/19323026
On the flip side, other studies have shown that borax guards against genetic damage in human lymphocytes:
In vitro studies on chemoprotective effect of borax against aflatoxin B1-induced genetic damage in human lymphocytes.
www.ncbi.nlm.nih.gov/pubmed/22526492
Boron compounds reduce vanadium tetraoxide genotoxicity in human lymphocytes.
www.ncbi.nlm.nih.gov/pubmed/21791386
I would imagine that if boron leads to genotoxic effects, then birth defects or negative health consequences would have been noted in the studies listed above on occupational exposure and fertility.
I am curious on what you might have to say about the fact that genetic alterations and apoptosis have been observed in the very same cells that borax has been shown to exert protective effects.
