Toxic/Heavy Metal

---

The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. These metals accumulate in the body in concentrations sufficient to cause poisoning. Heavy metal toxicity can lower energy levels and damage the functioning of the brain, lungs, kidney, liver, blood composition and other important organs. Long-term exposure can lead to gradually progressing physical, muscular, and neurological degenerative processes that imitate diseases such as multiple sclerosis, Parkinson's disease, Alzheimer's disease and muscular dystrophy.

•  Lead
Lead enters into the body system through air, water and food and cannot be removed by washing fruits and vegetables. It is a serious cumulative body poison, which can affect every organ and system in the body. Exposure to its high levels can severely damage the brain, kidneys and ultimately cause death and long-term exposure result in decreased performance in some tests that measure the functions of the nervous system; weakness in fingers, wrists, or ankles; small increases in blood pressure; and anaemia. Others are abdominal pain, anaemia, arthritis, attention deficit, back problems, blindness, cancer, constipation, convulsions, depression, diabetes, migraine headaches, thyroid imbalances and tooth decay.
•  Cadmium
Cadmium is very toxic, its long-term exposure to lower levels leads to a buildup in the kidneys and possible kidney disease, lung damage, and fragile bones. Hypertension, arthritis, diabetes, anaemia, cancer, cardiovascular disease, cirrhosis, reduced fertility, hypoglycemia, headaches, osteoporosis, kidney disease, and strokes are its some odd long term result.
•  Mercury
Mercury combines with other elements to form organicand inorganic mercury compound. Short-term exposure to high levels of metallic mercury vapors may cause lung damage, nausea, vomiting, diarrhoea, increases in blood pressure or heart rate, skin rashes, and eye irritation. Adrenal gland dysfunction, discouragement, dizziness, fatigue, headaches, hearing loss, loss of self-control, memory loss, mood swings, nervousness, numbness and tingling, pain in limbs, rashes, tremors, peripheral vision loss and muscle weakness are its long term effects.
•  Arsenic
Arsenic is regarded as human carcinogen from extremely low levels of exposure, having no possible beneficial metabolic functions for humans. Its low level exposure cause nausea and vomiting decreased production of RBCs and WBCs, abdominal pain and its long term exposure causes darkening of skin and appearance of small corns on palm soles. Other affect includes abnormal ECG, anorexia, fever, fluid loss, goitre, hair loss, headache, herpes, impaired healing, jaundice, keratosis, kidney and liver damage, muscle spasms, pallor, peripheral neuritis, sore throat, weakness and interferes with the uptake of folic acid.

Toxic elements from wastewater may contaminate agricultural soils, water supplies and environment and hence human food chain. The crops and the vegetables become contaminated either due to soil pollution or due to long exposure to polluted environment and accumulate unfavourable levels of metallic elements within them.

Rapid and high precision detection of toxic metal ions is one of the chief requirements today to combat environment pollution. Lateral flow test devices are powerful tools for on-site screening, and have attracted increasing attention in clinical diagnosis because of their simplicity, portability, long-term stability, and low cost. The CDIATM Toxic/Heavy metals test is an immediate method of screening agricultural products for heavy metals. The heavy metal testing allows the detection of free electrically active heavy metal ions in an aqueous solution by means of a simple procedure and in just a few minutes.
