The onset of non-communicable disease has been attributed in large part to environmental exposure to toxic chemicals, including persistent organic pollutants, volatile and semi-volatile organic compounds and transition metals. This review summarizes recent research into the causes and mechanisms of environmental disease onset and examines the role of oxidative stress as well as steps that can be taken to predict and lower the incidences of environmental diseases.
Introduction
Environmental diseases (ENVDs) are non-communicable diseases that result when people are chronically exposed to toxic environmental chemicals. Other contributory causes of ENVDs include radiation, pathogens, allergens and psychological stress. These other causative agents, however, are minor compared with the chemical ones, which are the primary focus of this review. ENVDs are generally late-onset, appearing only after numerous toxic exposures. In recent years, however, the age of onset has been trending lower [1]. For all the ENVDs discussed, it is appreciated that genetic as well as environmental factors contribute to the onset of these diseases. It has been shown, however, that incidences of ENVDs are greatly enhanced by exposures to toxic environmental chemicals, and that more than one exogenous agent may trigger any given disease. The World Health Organization estimates that as much as 24% of global disease is caused by environmental exposures . It has also been shown that 40% of cancers world wide can be prevented by lifestyle choices
Answer:
Lameness is not a single disease but a symptom associated with a range of different conditions. Herd prevalence rates can vary hugely between farms because many factors can predispose clinical lameness and because of differences in stockmanship and farm environments
