The fact “Chemical exposure effects experiences gradually over a long period of time” is never a lie when chemical exposure to certain chemicals occur. For many hazardous chemicals, the principle is that not all the agents capable of causing cancer and chronic toxicity are immediately observed in the body right after being entered. Unlike the serious repercussions of prolonged UV rays which can be seen quickly as in a few days to weeks, the harmful effects of prolonged exposure can appear as just early or late as few years or even decades. The time lags are caused by the bioaccumulation phenomena, an accumulation of toxic substances in the body over time and the disorders and the mutations that are progressive in nature, and their lagging effects accumulate in the body of the living organisms, and the disorders caused by them are discovered in the end. One should be careful and lessen chance of being in contact with hazardous substances even if short-term effects are not noticeable because it is situation of prolonged exposure, a person might get gravely diseased and even die.
