Research into environmental health hazards is obstructed by the general public's - and medical community's - lack of access to information on toxic substances. Unlike general health research, environmental health research is also limited by the lack of centralized mechanisms to articulate concerns over environmental threats from members of affected communities. Often those directly affected by environmental health hazards are the poor, the young, the elderly and the marginalised.
Environmental health research is hampered by environmental and health officials who continue to develop policies including children as "little adults" disregarding their unique multiple exposures to toxic substances. Officials also fail to differentiate between the adverse health consequences of toxic substance exposures between children in affluent and low-income communities, and fail to distinguish the disparate cultural, nutritional, and other factors among different ethnic groups.
Current guidelines and procedures that govern testing and risk assessment of industrial chemicals are based on a chemical-by-chemical approach, looking for one specific chemical's adverse health effects in a single exposure. Such an approach does not take into account the possible adverse effects of both cumulative exposures and simultaneous exposures to different chemicals. Current workplace policies regarding exposures - main source of general public policy - do not adequately protect the general public.
