Abstract
Mammals are distributed everywhere on the territory of the Pavlodar region (North-East of Kazakhstan). The narrow-crusted vole and steppe mouse species dominate in the anthropogenic habitats. Small mammals live in the conditions of emission of large enterprises of heavy industry. There are oxides of sulfur (IV) and nitrogen (IV), carbon monoxide (II), solid fluorides, hydrogen fluoride, benz(a)pyrene; V, Cr, Mn, Fe, Ni, Cu, Zn, Pb near large factories and highways. Animals receive toxic substances from food through trophic levels and through respiration. Insectivorous mammals suffer from pollution more than rodents. Fluoride accumulates in the bone tissue. Heavy metals are present in the coat, liver, kidneys, lungs, genitals and musculoskeletal system of mammals. The most dangerous for animal health is benz (a) pyrene, which is a mutagen in small quantities. The degree of influence of toxic substances decreases with the remoteness of the habitat from the sources of pollution.

Summary
ВЛИЯНИЯ НА АРЕАЛ Заканова А.Н.1, Ержанов Н.Т.1, Литвинов Ю.Н.2, Сергазинова З.М.1. Аннотация Млекопитающие распространены повсеместно на территории Павлодарской области (СевероВосток Казахстана). Мелкие млекопитающие проживают в условиях эмиссии крупных предприятий тяжелой промышленности. Рядом с крупными заводами и автомагистралями присутствуют SO2 (IV) и N (IV), СО (II), твердые фториды, HF, бенз(а)пирен; V, Cr, Mn, Fe, Ni, Cu, Zn, Pb. Животные получают токсичные вещества с пищей через трофические уровни и при дыхании. Насекомоядные млекопитающие страдают от загрязнений больше, чем грызуны. Тяжелые металлы присутствуют в шерсти, печени, почках, легких, половых органах и опорнодвигательном аппарате млекопитающих. Самым опасным для здоровья животных является бенз(а)пирен, который в малых количествах является мутагеном. Степень влияния токсичных веществ уменьшается, по мере удаленности ареала от источников загрязнения. Ключевые слова: мелкие млекопитающие, ареал, антропогенное влияние, токсические вещества, тяжелые металлы, эмиссия
