For the first time, a mycological analysis of outdoor urban environment (air, leaves, sealed surfaces) was carried in cities subarctic (Murmansk) and temperate (Moscow) climatic zones. The chemical composition dust deposited on leaves dominant tree species taken as an indicator air quality. Assessment complex impact factors (climate zone, type substrate, anthropogenic load) quantitative qualita...

Abstract Nowadays, many sites are considered waste, due to high potentially toxic metal (PTM) concentration. Recycling of globally critical metals requires development environmentally friendly processes for recovery. To study plants response elevated Zn and Cu concentration in soil, a greenhouse experiment was designed using hyperaccumulator Brassica juncea. Plants were irrigated daily with PTM...

Smoking remains the leading cause of preventable disease in the United States. Exposure to tobacco smoke leads to cancer, heart and lung disease, and addiction. The origin of the tobacco and cigarette manufacturing practices of counterfeit cigarettes are unknown. Because toxic metals are incorporated into the tobacco lamina during cultivation, the ambient metal content of the soil could produce...

background: milk is regarded as a unique source of food for all ages. when milk is exposed to various contaminants, including lead and cadmium, it is considered a risk to humans. the presence of some metal pollutants, especially cd and pb, facilitates their entry into the food chain and thus increases the possibility of their toxic effects on humans and animals. therefore, we decided to check l...

background: the removal of toxic metals from sewage and wastewaters is one of the most important concerns in the twenty first century. the removal of poisonous cr(vi) from aqueous solution by different low-cost available nanoporous adsorbents was investigated in the present study.  methods: fumed silica, bentonite (bn), hydrotalcite (ht), mcm-41, na-y, mordenite (mor) and sapo-34 were used at d...
