Toxicological problems of environmental protection

U uvodu se ukratko rezimiraju najvažniji izvori onečišćenja različitim toksičnim agensima koji mogu izazvati nepovoljne biološke efekte bilo putem profesionalne ekspozicije, stanovanjem odnosno boravkom u sredini s onečišćenom vanjskom atmosferom ili unošenjem u organizam putem hrane, vode za piće ili upotrebom različitih predmeta. Pored toga razmatra se problem učinka malih količina pojedinih toksičnih tvari kad se one unose u organizam ingestijom ili inhalacijom u toku dužeg razdoblja. Ističe se dalje da u proučavanju toksičnosti pojedinih onečišćenja treba obratiti pažnju i na interakciju različitih činilaca, posebno prehrane. U pogledu toksičnosti pojedinih onečišćenja okoline izdvaja se posebno vulnerabilnost fetusa i djeteta, za što se također navode primjeri. Na kraju se citiraju predloženi prioriteti za izradu zdravstvenih kriterija, kao i preporuke u odnosu na smjerove daljih istraživanja.In the introduction are briefly reviewed the most important sources of pollution with various toxic agents which may produce adverse health effects either through occupational exposure, dwelling in an environment with polluted atmosphere, through intake of food, drinking water or through the use of various objects. The problem of the biological action of small amounts of some toxic substances which enter the organism by ingestion or Inhalation over a certain period of time is also considered. It is pointed out that in the study of the toxicity of some pollutants attention should be paid to the interaction of various factors, particularly nutrition. Examples are given which prove that the fetus and child are specially vulnerable to the toxic action of environmental pollutants. In the end are quoted priority proposals for the setting up of health criteria and recommendations for further research
