MPC and ASLA
An atmospheric air is one of the most important objects of environmental protection. That`s why as the source of oxygen is given most attention by environmental and controlling authorities. For human health protection and preventing the changes in climate, the legislation establishes the certain requirements to enterprises which conduct the industrial emissions of pollutant substances into atmospheric air. Regulation of the emissions of pollutant substances is conducted through the legislative, normative acts, collection of specific indicators and instructions. The professional competence of the specialists of MCL, LLC is to carry out the calculations of pollutant emissions into atmospheric air for protecting the environment and preventing its contamination beyond the established norms.
For identifying a possibility to conduct the emissions of pollutant substances into atmospheric air while performing business activity, the specialists carry out the calculations of the maximum permissible emissions of pollutant substances. If it is required, the specialists can carry out the laboratory measurements for determining the actual volume and structure of emissions of steam-and-gas mixtures from equipment and GTU. By calculating the maximum amount of grams of emissions per second and the maximum concentration of mg of pollutant substances in one cubic meter of steam-and-gas mixture, specialists can calculate an air pollution from each particular source of emissions or the enterprise in general.
If the maximum permissible concentration (MPC) of each substance within the sanitary-hygienic zone of enterprise or in case of its absence within the residential area or an equivalent to such development, will not be exceeded the impact on the air status, it can be considered as insignificant and permissible. You can download the MPC here.
However, the MPC are established only for more popular pollutant substance such as: greenhouse gases (nitrogen, bioxyde, methane, carbon oxide), spiritus, dust, acids. There are more than five hundred of them. But, for example, an abrasive-metal dust is although formed at many large enterprises that have their own repair and mechanical workshops, but don’t have the established MPC. However, there are established the safe levels of impact for such substances (ASLI).
Approximately safe impact level (ASLI) and approximately safe acting level (ASLA) – hygienic normative establishing a single meaning of hygienic normative (ASLI) of pollutant substances in atmospheric air of settlements. You can download the ASLI here.
Therefore, actually, the MPC and the ASLI are the similar indicators establishing the level of maximum concentration of mg of pollutant substances in one cubic meter of steam-and-gas mixture close to residential development. The difference between the MPC means that also the MPC establishes the danger class of substance, it’s the maximum exceptional and daily average concentration. So, the level of permissible (safe) concentration is established for each pollutant substance as the MPC or as ASLI (ASLA).
MCL, LLC proposes clients a full range of services for obtaining a permission for emissions of pollutant substances into atmospheric air. Regarding to long-term and successful partner collaboration with the leading laboratory centers of Ukraine and the best scientific organizations MCL, LLC guarantees you an execution all specified services in time and by the at market price.
