Methods of using carbon nanotubes as filter media to remove aqueous heavy metals [PDF]

open access: yes, 2012
Although carbon nanotubes (CNTs) are well known to have a strong affinity to various heavy metals in aqueous solution, little research has been dedicated to exploit their use in fixed-bed water treatment systems (e.g., trickling filters).

Heavy metal deposition on plants in relation to immission and bulk precipitation.

open access: yesSilva Fennica, 1981
Monitoring of heavy metal accumulation in plants has been used to reflect the deposition of heavy metals in terrestrial ecosystems. In some cases, the accumulation rates in plants are linearly correlated to deposition measured as bulk precipitation ...
