The pine stems were cut from three different polluted environments - I^st trees degradation degree (weak pollution), II^nd trees degradation degree (strong pollution) and III^rd trees degradation degree (connected with very strong pollution). On the basis of obtained results it was stated that ...

Lichen-green-moss pine forests represented by Scotch pine Pinus sylvestris L. of the III-IV age classes were studied under conditions of various modes of aerial technogenic environmental pollution in the central part of the Kola Peninsula. It is established that the current trends in the formation ...

Data of palynological analysis of pollen of Pinus sylvestris L. under the conditions of technogenic pollution of the cities of Monchegorsk and Murmansk are presented. A high level of polymorphism of pine pollen is revealed, 11 teratomorphs are described. In samples from Murmansk, the proportion of...

The aim of this study was to evaluate the use of various indicators in the assessment of environmental pollution and to determine the response of pine to changes of pollution levels. Mezaparks is a part of Riga that has been subject to various long-term effects of atmospheric pollution and, in...

Carbon dioxide (CO₂) is the main anthropogenic greenhouse gas contributing to global warming. In this study, a series of KOH-modified biochars derived from feedstock mixtures (i.e., S3W7 biomass consisting of 70% pine sawdust and 30% sewage sludge; S5W5 biomass consisting of 50% pine sawdust and...

In urbanized regions with expansive impervious surfaces and often low vegetation cover, air pollution due to motor vehicles and other combustion sources, is a problem. The poor air quality days in Montreal, Quebec are mainly due to fine particulate matter and ozone. Businesses using wood ovens are...

Synthesizing new composites with better efficiency and stability from abundant sources offers an appealing prospect for removal of heavy metals and organic pollutants to address water pollution concerns. In this study, iron (Fe) and nitrogen (N) doped biochar (BC) composites were investigated for...

Pine needles are employed as alternative biomonitoring agents in atmospheric studies. In this study, pine (Pinus Pinea) components (needles and branches) and air samples were collected simultaneously to monitor polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and...

This study examines the dynamics of the composition of atmospheric precipitation and soil water in coniferous forests under the influence of atmospheric emissions from the Severonickel Copper-Nickel Smelter in Russia's Murmansk region. We studied dwarf shrub-green moss spruce forests and...

Several studies show that the interaction between airborne pollutants and pollen grains can lead to greater pollen allergenicity, and thus increase and exacerbate the incidence of pollinosis, all of which represents a major public health problem. This article analyses the possible influence of...
