Barriers, removing

The adsorbent can be used in several ways for field applications. In one method, the material can be placed into a trench installed in the path of a contaminant plume. The material wiU form an in situ permeable barrier, removing contaminants as they pass through the Humasorb. Another method involves injecting or angering the adsorbent into the soil to accomplish the same task. The technology can also be applied as part of an ex situ remediation system. 

Muizzuddin et al. recently studied contact urticaria in an attempt to define sensitive skin objectively.22 Skin responsiveness was assessed using balsam of Peru, which induces NICU. They found that individuals with self-assessed sensitive skin were more susceptible to NICU. This group was also more susceptible to stinging induced by lactic acid and stratum corneum barrier removal using tape stripping.

Oil absorbers powdered polyurethane foams possess excellent hydrophobic properties and can absorb various types of mineral oils (1 kg of powder can absorb even up to 3.43 dm of oil [58]). Therefore, such reprocessed foams are used for the treatment of scenes of road accidents, in plants involved in the production and trade of petroleum derivatives, and as barriers removing pollution of inland and sea waters.
