Substantial module 1. Municipal hygiene.

Concrete purposes:

· Analises hygienic, physiological and epidemiological properties of water, role of water at the epidemiology of infections desiases and helmintoses with water mechanism of transfer.

· Give hygienic estimation of organoleptic, chemical and bacteriological indicators of water from different water sources.

· Describe systems of water supply in the urbanic territories. Estimate methods of improvement water quality – organoleptic properties (sedimantation, filtration, coagulation), microbiological properties (desinfection), toxicological properties (detoxification), deactivation.

· Estimate degree of atmospheric air pollution and its dangerous for public health.

· Propose system of hygienic actions for sanitary protection of atmospheric air pollution (technological, planning, sanitary-technical, legislative).

· Give hygienic estimation of soil quality on the data of laboratory research.

· Propose plan of hygienic actions on the sanitary protection of soil to prevent diseases.

MPC - maximum permissible concentration at which action throughout life there is no direct or indirect impact on the present and future generations, not decreasing human performance without deteriorating its health and sanitary living conditions. There are 2 types of MPC: maximum single and daily.

Approximate safe level action (ASLA) - is the maximum concentration substance that is recognized at estimated safe act on man and adopted as a temporary sanitary standard allowable substances in the air of populated areas. ASLA established on the basis of short-term studies.

Maximum allowable pollution index (MAPI) air - relative integral criterion for assessing air pollution settlements, which characterizes the intensity and nature of joint action and joint action character of the totality of present therein contaminants.

The outer limits of SPZ facing the residential development, concentration and levels of pollutants do not exceed their hygiene standards (MAC, GDR), on the verge of resort and recreational area - the ratio of 0.8. In the SPZ should not allowed to build houses with gardening area, hostels, hotels, homes for visitors, kindergartens, schools, medical and health institutions of general and special purpose from the hospital, substance abuse clinics, sports facilities, gardens, parks, gardening Society equip security zones of water sources, intakes and building water distribution network.
