Abstract

Lead (Pb) is a substance that can cause serious damage to the brain and kidneys, soften bones, adverse effect to the reproductive system, and can be fatal. Long-term exposure to the substance can damage not only children, but also adults' nervous systems. Lead does not belong into the category of toxic substances due to its effects on the human body. It is considered as a harmful substance. In this study, we analyzed lead concentration in liver and kidney of cattle, horse, sheep, and goat from the mining areas located in the Ulaanbadrakh, Zuunbayan, and Airag soums of Dornogovi province. As a result, the level of lead in the liver of sheep and goat Zuunbayan soum of Dornogovi province was slightly higher than in other soums. The content of heavy metals in water and soil samples did not exceed the international standard average.

Highlights

Mongolian nomadic pastoral animal husbandry has a long history and tradition of managing the health and productivity of livestock suited to soil, water, feed supply, and plant compositions through the rotational use of pasturelands
This research was conducted under the goal to ensure food safety and quality assurance, bring the food control system to the international level, and develop measures and recommendations to protect livestock from technopathic diseases caused by mining industry wastes
As part of the study, the lead, a heavy metal, content was determined in the soil and water as well as in the some internal organs of animals grazing near mining area

Summary

Introduction

Mongolian nomadic pastoral animal husbandry has a long history and tradition of managing the health and productivity of livestock suited to soil, water, feed supply, and plant compositions through the rotational use of pasturelands. Results of the testing revealed that approximately 55% of fruits do not ensure toxicological and bacteriological safety and heavy metal [2]. Research in this area has become one of the actual problems. This research was conducted under the goal to ensure food safety and quality assurance, bring the food control system to the international level, and develop measures and recommendations to protect livestock from technopathic diseases caused by mining industry wastes. As part of the study, the lead, a heavy metal, content was determined in the soil and water as well as in the some internal organs of animals grazing near mining area
