Poisoning, Toxicology, Environmental HealthToday’s level of poisons humans have to face is a lot more than it was maybe 50 years back.
Humans and animals as well are being poisoned through several different means. Though not intentional it is harming the way healthy humans live, also giving way to new and varied types of diseases each day.
Poisoning can be through foods, air inhaled, water, toxins, many different ways.
Air pollution is known to be one of the major contributors to poisoning, air due to industrialization and burning of fossil fuels has become harmful enough to give people conditions like asthma and cancer. The toxins in the air are increasing the risk of cancer among adults as well as children alike.
There is a degree of poisoning that a human body can take excessive exposure to toxins and pollutants results into irreversible illnesses like the brain disorders, coma, and death.
Toxicology is a science that studies the relationship of a dose of toxic substance and its effect on the body.
This science considers that almost each substance is toxic under specific circumstances, even water is considered toxic, however, passive toxins do not have much effect on the body the way active toxins have, therefore these are considered more dangerous.
The most common way of poisoning other than air pollution is the food.
Not food directly but through the pesticides that are used in growing crops. Each year there is tremendous use of pesticides used to grow crops so that the human race can be properly fed through the crop that grows.
However, pesticides are proving harmful to the consumers of the food, farmers and workers that use the pesticides. Several governments throughout the world are now using techniques to screen the pesticides being used for growing crop; only those pesticides which are government approved are being used to avoid excessive damage to human and animals alike from food.
Care is also being taken by the government to help farmers induce different types of fertilizers and pesticides in growing crop, this is so that the environmental health is being taken care of, it was found that almost each lake and river in USA was polluted with the fertilizers.
Lead poisoning is another type of hazardous poisoning today, lead poisoning causes symptoms like reduced levels of brain activity, low IQ, low memory, lethargy, and gastrointestinal problems like constipation, diarrhea, weight loss, etc., are due to lead exposure. Excessive exposure to lead can also lead to learning disability among children.
