Influence of external environmental factors on human health

It is a given general principle of the influence of ecological factors on human’s and animal’s organisms that the effect or intensiveness of its influence depends on the nature of the factor itself and on its quantity (for chemical factors) or dose (for physical factors). Those dependencies of the influence of concentration or dose of the certain ecological factor on this or that vital indicator (in the long run it could be the quantity of population) are non monotonous and are generalised on the figure 6.2.

Interrelation between the state of the environment and people’s health has become unique and indisputable. High quality of the environment does not guarantee 100% health of the population but its influence would not become aggravating for the people’s health. At the same time deterioration of the environment resulting from human activity inevitably increases risks for human health. It should be known and remembered, at the least. At the most, people’s life strategies should be designed in such a way so that it minimises negative impact on the environment, the environment, which we are living in.
