We have previously discussed the role of lead on neural development and also we have addressed the issue of particulate matter in regard of public health. Consequently we have proposed that as a measure of preventive healthcare, these substances should be eliminated from the environment within space settlements.
Another well known harmful substance is arsenic. Though it has been known for centuries that arsenic is poisonous, scientists have now found a link with environment arsenic and heart disease. Therefore, consistent with our preference for preventive healthcare, we recommend that space settlements to heavily restrict the use of arsenic.
Other negative effects of exposure to arsenic are:
- increased probability of cancer, even after decades
- early puberty and obesity due to prenatal exposure
However, there seems to be an effective method to remove arsenic from water using iron-enhanced charcoal.
