Did you know that worms may remove, amongst others, heavy metals and soil pesticides?
WORMS WORK AS BIOACUMULATORS!
Pollution and soil contamination are a problem today on a global scale. A substantial fraction of arable land is currently polluted and contaminated due to mining activities, pesticide use, oil spills, deposition of toxic materials resulting from landfills closure, among others.
Learn how worms can solve this serious environmental and public health problem through its action on the removal of various chemicals products with an anthropogenic origin. Currently, remediation methods do not present themselves economically and environmentally viable, and in most cases, cause the migration of pollutant / contaminant to another location, and ultimately does not solve the problem. Other methods of remediation promotes contaminants leaching represent a inconvenient as this waste will need an appropriate treatment or final disposal.

Worms can accumulate in their tissues concentrations of various heavy metals, hydrocarbons, among others.
Vermirremediation has emerged as a low-cost technology for the removal of these elements in a practical and efficient way, promoting in soil recovery and rehabilitation.
