As nanotechnologies are developing actively, it is necessary to conduct research of potential toxicity of metal-containing nanoparticles for living organisms. Because of their specific properties, they can enter a body and lead to adverse effects.

The article presents the dynamics of the content of iron and manganese ions in the surface waters of water bodies of Brest region in the period 2008 – 2017. The study of physico-chemical forms of metals is a promising direction for the integrated assessment of the degree of pollution of water bodies.

This article provides a description of the largest chemical enterprises in the region, the main indicators of polluting substances, and also analyzes the impact of the chemical industry enterprises of the Gomel region on the air condition in the period 2010-2015.

The article presents the results of a study of soil toxicity in some roadside areas of Brest with different anthropogenic stress. The research applies a method of biotesting. Lepidium sativum L. is taken as a test object.

The ichthyofauna species diversity of the Pripyat River and its tributaries – the Goryn and Vetlitsa rivers comparative analysis was carried out. The greatest species richness for the Pripyat River (10 species) is noted. According to the fish species composition the Goryn River is close to the ...

This article shows the research results of relation between arbuscular micorrizzal fungi and photosynthesis rate at different stages of succession. These relations have been studied insufficiently so far.

The article considers phenological indicators observed in the wildlife reserve “Stolby” in the summer period from 2005 to 2016. Studying phenological phenomena of the reserve “Stolby” allows tracing the impact of global climatic changes on the landscape and its change.

The content of mobile forms of some heavy metals in sod-podzolic soils of Western Belarus was defined. It is shown that the content of lead (4.56 mg/kg) and copper (0.93 mg/kg) in natural (native) soils exceeds an average background level for the soils of Belarus.

The article shows that sewage sludge (scop) formed during the production of paper can be processed by composting with the use of intensifying preparations. The quality of the compost was determined by physicochemical and biological methods.

The article estimates geo-ecological conditions of the administrative districts of Brest region using integration of different quality indicators. Five groups of districts with different levels of environmental disturbance are identified.
