The occurrence of microplastics into the ecosystem has become and eminent threat for environment as well gets extensive attention in recent times. Microplastic existence severely affected lakes, rivers, oceans, coastal zones, even polar zones biome. Microplastics (primary microplastics) mostly come from used products by shattering larger fragments. Through runoff, microplastic enters either aqu...

Continuous measurements of meteorological parameters, gaseous pollutants, particulate matters, and the major chemical species in PM2.5 were conducted in urban Hangzhou from 1 September to 30 November 2013 to study the potential sources and formations of PM2.5 pollution. The average PM2.5 concentration was 69 μg ̈m ́3, ~97% higher than the annual concentration limit in the national ambient air qua...

The present work aims at a detailed study and explanation of the pollution transport in the air basin over South-westem Bulgaria and Northem Greece and assessment of the air pollution exchange between Bulgaria and Greece. Some weli known specific climatic air poilution effects were studied and explained. Calculations were made ofthe S02 poilution ofthe Balkan peninsula from both Greek and Buiga...

T wo decades of research have shown that air pollution can trigger heart attacks, strokes, and irregular heart rhythms, particularly in people already at risk for these conditions. Several reviews of these studies, including 2 American Heart Association scientific statements, describe the scientific findings and conclude that air pollution poses a risk to heart health. You can help protect your...

PURPOSE OF REVIEW Current levels of air pollution are consistently associated with asthma development and morbidity among children, suggesting that current regulatory policies may be insufficient. This review will describe recent studies that have examined specific emission sources or components of pollutants that may be associated with pediatric asthma and identify subpopulations that may be p...

The sulphur isotope content, ôS, of sulphate from two potential pollution sources in Volga-Akhtuba flood plain surface waters was investigated. Isotope compositions of sulphur compound emissions from the Astrakhan Gas Condensate Complex and the Astrakhan Pulp and Paper Mill were significantly different which provided an opportunity to differentiate effects from these two emission sources on nea...

Nonpoint sources of pollution that contribute fecal bacteria to surface waters have proven difficult to identify. Knowledge of pollution sources could aid in restoration of the water quality, reduce the amounts of nutrients leaving watersheds, and reduce the danger of infectious disease resulting from exposure to contaminated waters. Patterns of antibiotic resistance in fecal streptococci were ...
