Environmental Toxicology and Bio-Remediation
In the race for economic power, many industries have proliferated and medical advancements have increased the average human life span, slowing death rates, increasing birth rates and reducing still-born birth to contribute to population growth. To keep up with growing demand, agricultural lands are enhanced for production by applying chemical fertilizers, pesticides and insecticides. Industrial waste, agricultural waste and other wastes are released unconfined into the environment in all states of matter solid, liquid, gases and sub-surface environment causing environmental degradation. The environment toxic compounds of industrial hazardous waste and agricultural wastes have adversely impacted due to their non-degradable nature and continue to impact flora, fauna and humans alike by entering food chain and cause bio-magnification. To remedy the toxins present in environment bio-remediation is considered as a cost effective eco-friendly best intervention.
Bio-remediation is a process where bio-organisms (including microscopic organisms such as fungi, algae and bacteria) remove, neutralize or make environmental pollutants less toxic through metabolic process. The organisms used are either indigenous or genetically engineered to react to the environmental pollutants. Bio-remediation affects the toxic pollutants such as agro-chemicals, pesticides, hydrocarbons, chlorinated compounds, heavy metals, xenobiotic compounds, nuclear wastes etc., by reducing, detoxifying, degrading, mineralizing or less detoxifying them. Microbes can live below zero degrees Celsius and can withstand high temperatures produced by hazardous compounds. Microbes can be classified to aerobic or anaerobic and they act when they contact the compound such as its chemical nature, physio characteristics of environment like soil, pH, temperature, oxygen and nutrients and its accessibility to other existing micro-organisms.
Bio-remediation techniques can involve both in-situ and ex-situ techniques. In Ex-situ technique the pollutant is dug out from the pollutant site and is transported to another site for treatment. Ex-situ treatment involves solid-phase and slurry-phase treatment, bio-pile technique, land farming and Bio-reactors to treat the pollutant area. In-situ technique treats the pollutants in the pollutant site and is cost-effective than Ex-situ technique although both have advantages and disadvantages of their own. In-situ technique uses bio-slurping, bio-venting, bio-sparging, permeable reactive barriers etc., in dealing the pollutants. Through bio-augmentation microbes are enhanced in the polluted site to degrade the toxic compounds. However, bio-remediation takes time as it is a natural process, moreover not all compounds are disposed and when the process is trapped in intermediate stage it further accelerates pollutants rather than curbing them. Nonetheless it has proven thus far to be a viable cost- effective efficient solution without producing other inconvenient consequences. This special issue mainly focuses on the environment sustainability through bio-remediation and its effectiveness in removing toxic compounds from environment by applying various bio-remediation techniques.
