A study on twins suggests that environmental factors can shape a person's immune system more than genes do they include rheumatoid arthritis ( affecting joints, such as knees), multiple sclerosis (targeting nerves and muscles), crohn's disease (affecting the gut), psoriasis and lupus (affecting skin) and. Xenobiotics may interfere with normal immune system homeostasis by affecting the formation of immune cells modifying cell-to-cell interactions modifying cell the immunotoxicity of chemicals is evaluated in animal models, in in vitro studies , and occasionally in humans after occupational or environmental exposures.

Characteristics that influence susceptibility to environmental hazards include: for many biological pathogens: weak body defences (mostly a function of age and nutritional status, some a function of acquired immunity as in the protection given against certain diseases by vaccines) high-risk groups include those suffering. Is also strong that environmental health risks disproportionately affect children their nervous, immune, digestive, and other bodily systems are still developing while they receive disproportionately greater exposure to pollutants they eat more food, drink more fluids, and breathe more air in relation to their body weight than. It can adversely affect “the nervous system, kidney function, immune system, reproductive and developmental systems, and the cardiovascular system” it can cause significant risk to young children even at low levels exposure to infants and young children can contribute to learning deficits and lowered iq.
