For instance the general knowledge with regards to toxic impacts on freshwater organisms is mostly restricted to average temporary toxicity. Again there is limited information on factors influencing these toxic substances and how they are manifested within an organism (Dabrunz, et al. , 2011). The most important recent as well as near-term issues of medicine is toxicity in organism or ecological systems, particularly because there is no concrete experimental that on unintended  and adverse  effects of toxicity as well as how these can be detected. In spite of the issues  of health and  safety dangers linked to toxicity, there is  a  no important quantit ative analysis  and  empirical data  on risk assessments. A great deal of this is as a result of scientific ambiguity over permanent medical  reactions. If toxicological issues  are to be tackled, the question is how  we tackle these issues in light of no concrete empirical information (Jaipreet, 2008). This paper highlights some of the factors associated with toxicity as well as their manifestation within an organism. Toxicology and ToxicityToxicology can be defined as “the study of the adverse effects of chemical, physical or biological agents on living organisms and the ecosystem, including the prevention and amelioration of such adverse effects” (Society of Toxicology, 2005). Toxicity (or hazard) on the other hand, is the inborn ability of an agent to bring about damage. This property will only change if the agent is changed in some way. It will not change with changes in conditions of use or exposure. Factors that influence the toxicity of a substanceOne of the factors is duration of exposure. This can be categorized under three, acute, subacute, sub chronic and chronic. Severe toxicity refers to a cause and an impact that is apparent in terms of days and weeks. Exposure to the chemical substance can either be severe or chronic in a poisoning condition. Severe poisoning usually takes place when a particular exposure causes a direct impact while chronic poisoning refers to impacts found to be following any constant permanent exposure to moderately low levels of the chemicals (Nweke and Okpokwasili2010). Apart from the duration, exposure routes are also very significant in influencing the toxicity of a substance in an organism. The impacts of exposure are significantly determined by the exposure routes usually considered to be air and water pollution, contaminated food, and contact with toxins in both the normal and work surroundings. Some chemical substances, e.g. parathion, are similarly toxic by all three routes of exposure although the most of th em are not similarly toxic by all the three routes of exposure, regardless of the period of exposure. Routes of exposure to direct include contaminated air, water, soil, food, and customers productsFurther, types of an organism/animal or physiology of the organism is very vital. The brutality of a substance's toxicity is the function of its association with the bodily processes of a specific living being. For instance, chocolate is relatively toxic to canines although modestly to other animals. Consumed in very big portions, vitamins too may cause toxicity in humans. Theobromine, a chemical that originates from chocolate, is poisonous to dogs although not to rodents.
