It was expected that at the existing pollution levels, embryonic losses caused by direct toxic effect of Cd shouldn’t exceed 7%; however actual losses significantly exceeded extrapolation results. Distinctions observed are caused by impact of external and internal factors influencing reproductive potential on fulfillment of reproduction of animals in natural populations.</p></abstract><trans-abstract xml:lang="ru"><p>На основе исследований репродуктивных параметров мелких млекопитающих из природных популяций (на примере рыжей полевки), обитающих в зоне действия крупного предприятия цветной металлургии, и сопоставления полученных данных с результатами токсикологических экспериментов (хроническая затравка самок крыс Cd), сделана попытка оценить величину прямых эффектов токсического действия Сd. Ожидалось, что при существующих уровнях загрязнения, эмбриональные потери, вызванные прямым токсическим действием Cd, не должны превышать 7 %, однако, фактические потери существенно превышали результаты экстраполяции. Наблюдаемые различия обусловлены действием на репродукцию животных из природных популяций внешних и внутренних факторов, влияющих на реализацию репродуктивного потенциала.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pollution of the environment</kwd><kwd>cadmium</kwd><kwd>natural populations</kwd><kwd>red –backed vole</kwd><kwd>embryonic losses</kwd><kwd>toxicological experiment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>загрязнение среды</kwd><kwd>кадмий</kwd><kwd>природные популяции</kwd><kwd>рыжая полевка</kwd><kwd>эмбриональные потери</kwd><kwd>токсикологический эксперимент</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Talmage S.S., Walton B.T.
