In general, EI refers to a wide range of symptoms and causes, all traceable to the rapid changes we have made to our air, water, and food over the past century through pollution, chemical proliferation, and other causes.
Chemicals can and do affect our health.
People can become supersensitive from major exposures so that small amounts of chemicals in daily life trigger symptoms. Low-dose, prolonged exposures can cause gradual, subtle but long term damage, and can be much harder to detect and prevent. People vary greatly in their response to chemical exposures. Some will hardly react while others may become very ill. Among the most vulnerable are women, unborn babies, allergy sufferers, workers in high-risk occupations, the poor, the young, the elderly, and the chronically ill.
