Total maximum daily loads (TMDLs) are used to protect water bodies based on their assimilative ability and are transferred as a maximum allowable load, which is the sum of all pollution emissions in a watershed that cannot be exceeded. This allowable load... see more

The paper reflects the analysis of Cd impact on the total activity (nM pyruvic acid/ml s) of alanine aminotransferase (ALT, EC 2.6.1.2) nitrogen metabolism and the content (mg/ml) of water-soluble protein fraction (albumin) in Glechoma hederacea L. leaves... see more

The paper includes analysis of research of Cd impact on the activity of the enzyme of aspartate aminotransferase (AST) nitrogen metabolism and the content of water-soluble protein fraction (albumin) in Glechoma hederacea L. leaves, which dominated in the ... see more

The ground level concentration of an air pollutant is obtained using the Gaussian plume model. However, the effective height H of the pollutant has been considered as a function of the ground level coordinates x and y. Extreme radius of the stack is d... see more

This study aims to determine if there is variation in precipitation concentrations in Chile. We analyzed daily and monthly records from 89 pluviometric stations in the period 1970–2016 and distributed between 29°12' S and 39°30' S. This area was divided i... see more

Safety of milk can decline because of high concentrations of steroid hormones like 17ß-estradiol, which is associated with the development of some oncological diseases and reproductive disorders. We studied the effects of thermal processing of raw milk an... see more
