  • Pollution on top of the world

    Nearly one-fifth of the earth’s surface is comprised of mountains that play a role in the storage and distribution of fresh water, with one-tenth of the world’s population relying on that mountain snowpack as their sole source of fresh water. Understanding the amount of pollutants in soil and snow is critical to maintaining the quality of alpine water sources, and is the subject of a ...

  • How plants absorb pollutants

    The environmental concern is great when considering the role of toxic contaminants in the plant-soil relationship. Understanding plant’s absorption and accumulation of these contaminants from the soil would be incredibly beneficial. One highly carcinogenic contaminant commonly found in soil is called polycyclic aromatic hydrocarbons. They are the byproduct of the incomplete combustion of ...

  • Reducing runoff pollution in the US

    Over the past century, runaway development has paved over forests, fields and wetlands across the country. Along with urbanization has come the problem of 'urban stormwater' – rainwater that washes over dirty surfaces such as roads, buildings and lawns and becomes a major source of pollution in rivers, lakes and bays. While much has been achieved in the past 30 years to limit pollution from ...
