Lorax Environmental Services Ltd.

Lorax Environmental Services Ltd.

Lorax Environmental Services Limited (Lorax) is a privately-owned, environmental consulting company that provides leading-edge environmental and project management services to the mining industry. Our corporate goal is to provide the highest calibre environmental services in the most cost-effective and timely manner and, where appropriate, implement innovative techniques and approaches to addressing environmental issues faced by our clients.


Lorax hosts a team of highly qualified and experienced professionals capable of conducting and managing environmental projects during all phases of mine development. Lorax's expertise, which is both highly technical and grounded in practicality, has been utilized on projects worldwide in Canada, Per, Chile, Bolivia, Suriname, Guyana, Panama, Venezuela, Philippines, Indonesia and the U.S. These have included:


feasibility and baseline studies in support of marine and terrestrial Environmental Impact Assessments (EIA) for mine permitting, subaqueous tailings discharge and development of closure plans;
acid rock drainage prediction and assessment;
the development of waste management strategies;
operational monitoring for compliance and
the design and operation of treatment systems.


The practical mining experience of Lorax scientists is supplemented by our close association with academic institutions and the private sector. Our academic associates are internationally respected scientists from the fields of oceanography, geochemistry and biology and provide high-end scientific input to our projects. This enables us to design and implement studies with a solid scientific foundation, which will in turn benefit our clients in gaining regulatory approval for their environmental studies by establishing a high degree of credibility.

Diffuse Gradient In Thin-film (dgt) Technology Directly Measures Biologically-available Metal Concentrations In Natural Waters And Effluents.
Lorax Environmental Services Ltd. is using and marketing the new water sampling technology known as DGT (Diffusive Gradients in Thin-films) or the 'gel-sampler' for the in situ determination of biologically-available metals in aquatic systems. Trace metal biological availability is poorly represented by conventional water sampling approaches. It is now well known that metal toxicity is strongly influenced by complexation reactions that occur in all natural aquatic systems. Thus, in many instances, trace metal availability to aquatic organisms is significantly different from either the total or dissolved metal concentration. The gel-sampler accumulates biologically-available metals (i.e., that fraction that is both dissolved and uncomplexed) onto an ion-specific resin. Particulate and strongly complexed metals are excluded in the same way that they are unavailable to biota. The behaviour of the sampler has been 'calibrated' in the field and laboratory and has demonstrated a very strong correlation to biological-availability as determined through bioassays on several test organisms. The sampler is very easy to use and deploy, and obviates many of the classic problems encountered by conventional water sampling technologies. Advantages of the gel-sampler include: direct measurement of trace metal biological availability; preservation and direct determination of metal speciation; elimination of the need for sample filtration; elimination of contamination during sample collection; elimination of the need to ship water samples; ability to easily archive samples for comparatively long periods of time; preconcentration of metals thereby improving detection limits; removal of metals from the sample matrix for improved analysis; integration of biologically-available metal concentration with time; insensitivity to changes in salinity from fresh water through seawater. A synopsis of the current status of the gel-sampler technology and a more detailed overview of the technology is presently available from Lorax.
